Postcards from Ecsite 2018

Ecsite, the international non-profit whose name is the acronym of European Collaborative for Science, Industry and Technology Exhibitions, has been an event since its founding in the early 1990’s. Bringing together a European network of science centers and museums, its vision is to foster creativity and critical thinking in European society, encouraging citizens to engage with science. Ecsite’s history provides a fascinating glimpse into the evolution of an institution whose mission is to inspire organizations that engage people with science, not just in Europe, but also worldwide.

Our partners at Wezit attended Ecsite 2018, which was held at the Natural History Museum of Geneva, Switzerland, June 7 through 9.  Wezit’s Ségolène Valençot shared with us some vignettes of various gatherings she attended.  These are her postcards from this event.

The setting

We are still on an #Ecsite cloud mode!  This year’s conference took place in the beautiful city of Geneva, during the first days of June. Perfect weather, the air was filled with the energy and the great ambiance of 1,182 professionals from 58 countries, all gathered for three days to reinvent how we communicate, teach, learn, and think! After all…no wonder why this year’s theme was Creative collisions!

Great audience asking key questionsThe art of recontextualizing collections

Wezit attended the Recontextualizing Collections panel; the speakers presented real case scenarios on how museums and their collections can increase the contact with their audiences.

First, we listened to Maria João Fonseca, the Interim Executive Coordinator of the Natural History and Science Museum of the University of Porto, who shared with us how they made a priority to engage their visitors. Thus by creating stories within stories, museums within museums, using the documentation available in the collections. For example, by interpreting the 1930’s dreamy Portuguese poets, displays are used to showcase the Whale skeleton at the Museum of Porto Gallery.

A particular thought to the idea of museums within museums was taken by a scenography incorporating Cabinets of Curiosities dating from the 19th and the beginning of the 20th century. Touching the visitors’ emotions, moving their curiosity, attracting them by using a mix of stories, as well as history and literature – the idea was to give life to objects and ultimately use them as a learning tool!

Lastly, Fonseca explained how important it is to evaluate how visitors experience and understand these museography proposals and scenographies.

Starting from more or less the same principle of the “museum within museums” idea, Beat Hächler, Director of the Swiss Alpine Museum at Bern, Switzerland, gave us his insights on  “museum intimacy”. He talked to us about dropping the permanent exhibition principle and go for a kind of mini-exhibiting units, such as pop-up schemes or event venues. Moreover, he emphasized the needs of creating unique spaces that help visitors to connect to the collections, those museum objects surprising them by finding out about things they never knew about the collection – as if the exhibit and the visitor were in a conversation and they shared their stories. Swiss Alpine Museum, Bern

Bringing visitors closer to the museum and making it more available to them by revealing the “behind the scenes” aspects of the collection and its motivations, is also a priority for Grégoire Mayer, co-director at the Musée d’Ethnographie Neuchâtel.

And if you enjoyed Shawn Levy and Chris Columbus’ film “A night in the museum”… then you will agree with Hervé Groscaree, from the Natural History Museum of Geneva,  and invite visitors to sleep and do overnight museum activities , move with visitors in the nature and feel authentic experiences in relation with the collections of the Museum!Museum d'Histoire Naturelle

Balancing Renovation

Even though it does not compare the size and magnitude of a museum, if you ever went through a home or office renovation while still living at your place, you would relate to this session and be open to learn and listen about what the speakers & participants have to share!

Every once in a while, every museum, science center – no matter their size, will eventually go through a renovation. Not only construction-wise, but also concerning the updating of their presentation techniques.

Some institutions will opt to open their doors while going through these improvements; others will temporarily close, others will make key pieces of their collection available to visitors, such is the case of the Musée Lorrain. Wezit completed tactile digital tables showcasing key pieces of their collection, while the museum’s temporary closure, and those are available online for visitors to admire until they reopen their doors.

As part of a constant search to understand the challenges museums and institutions go through, we attended the Balancing construction works and visitor satisfaction Conference at the #Ecsite2018 conference. In this cooperative gathering, speakers share their experiences, strategies and results, adaptable to smaller and to significant bigger organizations.

Speakers from centers located in Amsterdam, Belgium and Germany, pointed out in a TO DO LIST presentation general tips, ideas ranging from financial planning, visitor communication as well as content development.

The real case scenarios presented included the following museums, which were there as participants to this session:

The Jaermuseet in Norway: They mastered in getting feedback from their visitors with customizable surveys, and open-ended questionnaires.

The Jaermuseet obtained an average of 80% responses from families and teachers. The results had a satisfactory rate, which motivated the staff, and uncovers ways to improve. Moreover, surveys referring to open and recreational spaces echoed the museum’s presentation and how it is perceived by its visitors. Overall the Jaermusset focused their visitors as the best museum’s ambassadors!Balancing renovation

On the other hand, more interesting real case examples discussed were: The Eureka Science Center which has been conducting visitors analysis since the 1980’s, enabling them to have a good knowledge of what they offer in their cultural and scientific presentation.

Visitors identify the Center as a place to do family activities; furthermore, the tracking of their visitors’ behavior from the moment they buy their ticket online for the duration of the tour, and lastly the rise of the website and social media as a medium to obtain what motivates and interests their audience.

Maarten Okkersen talked to us about the Internet component in the museum sphere and the power of blogging moms that follow the museum’s latest happenings. How they can be a good pairing with these institutions, which leads to the importance of knowing the basic of SEO and the interpretation of google analytics.

Furthermore, how it can attract those that are considered visitors and non-visitors, hence, the museum becomes not only a cultural place but also perceived a place of fun and entertainment.

Finally, the Copernicus Center in Warsaw shared their views on balancing between data and intuitions.. Now you should be in route towards your institution’s customer satisfaction journey!

Oxford Street project: big data and virtual reality in urban design

As we know, urban planning concerns itself with the design and regulation of the uses of space in the urban environment, and on the location of human activities within it.  Regarding existing urban settings, a key concern is understanding how the space is currently used, and how it would be affected by change, both from redesign, or simply from increased use over time.

This story, shared by Senior Transport Consultant Francesco Angelelli, highlights how Atkins, a leading international consulting company, used an innovative approach leveraging the latest technologies to study human behavior and use patterns at an iconic place: Oxford Street in the City of Westminster, one of the most famous destinations in London.Oxford Circus

The Urban Setting and its Challenges

Originally part of the Via Trinobantina, a Roman road between Essex and Hampshire, Oxford Street has existed for over 2,000 years.  It became Oxford Street in the 18th century, when it began to change from residential to commercial.  Today, it is Europe’s busiest shopping street, with half a million daily visitors.

Because of its popularity among tourists and shoppers, the street’s capacity is under increasing pressure. Businesses compete to secure a high-profile presence in the area.  As a result, there are growing concerns about traffic pollution, general accessibility and pedestrian safety.  In addition, the opening of the Elizabeth Line, the railway route built by Crossrail, under construction since 2009, due to open in December 2018, is expected to increase footfall and exacerbate existing problems.  All of this has prompted a much needed discussion about the need to reshape the area’s public use.

The Crown Estate appointed a multi-disciplinary team to develop proposals for Oxford Circus and its surrounding streets.  Atkins’ pedestrian modeling team was involved in the proposal’s assessment to accommodate the increased demand, improving accessibility while providing visitors with a world-class experience.

The Solution

Key project challenges were the size of the area to be assessed and the large number of pedestrians involved.  Developing a model capable of simulating existing conditions in such an environment demanded innovative data collection methods supported by traditional survey data. After evaluating several survey technologies, the Atkins team opted for WiFi Survey: monitoring the movement of active WiFi- enabled devices throughout the study area. WiFi survey provides relatively clean samples with high sample rates.  In addition, it enables relatively straightforward long-term comparison between different monitored areas, which would be difficult, if not impossible using traditional sampling methods.

Following their standard approach, the Atkins team developed a base-year model which simulates existing conditions to a reasonable level of validation. The methodology has been successful in the calibration of the base model (R-Squared of above 0.96 and GEH < 5 for most measured flows).  They used this as a basis for the development of future year scenarios for the assessment of design alternatives.  The 2018 demand level has also been increased to develop 2019 models.Oxford Street in VR

All models were rendered in a 3D Virtual Reality environment, so the team could literally experience walking through the base model. This proved to be an incredibly useful aid in refining and visually validating modeling assumptions, thus solving a common problem in the pedestrian modeling sector, as standard software only allows modelers to visualize simulated crowds from a distance. The 3D Virtual Reality environment also enabled exploring spatial improvements with the design team in a seamless and highly effective manner.

The setup

The Atkins team deployed 21 WiFi devices (“nodes”) on building cornices. The nodes were attached to the building’s floodlight mains and used 3G/4G connections to stream data in real-time.  Behind the scenes, Accuware’s WiFi Location Monitor system determined the approximate location of all WiFi devices by triangulating their positions based on their signal strength.Nodes. Installations. Tracing dots.

Weekday profiles support peak-period assumptions

Data collected through WiFi Location Monitor proved essential for monitoring conditions on the ground.Volume of daily movement

One day, August 11th at 9 AM, the number of devices detected peaked and then suddenly dropped. As this trend was very unusual for this time of the day, the team worried that the system was experiencing technical problems. But just then they learned that Oxford Circus station had been evacuated because of a train on fire. With the station temporarily out of service, the overall population in the area was lower than usual. This incident revealed that the data captured will be very useful for planning emergency operations.

O/D matrices for weekdays and weekend

As the datasets were growing week by week, the team began analyzing the data and obtaining useful insights both for modeling and for stakeholder information. For example, the combination of Origin-Destination (O/D) matrices and daily profiles for both weekdays and weekends enabled them to define different areas by showing which were commuter-driven, leisure-driven, and neutral; where neutral is the configuration that maximizes public space usage throughout the week, an important indicator of the quality of public spaces.Origin-Destination (O/D) matrices

Pedestrian speeds on Regent St and Argyll St

The analysis covered sample speeds on Argyll Street, which is a pedestrian lane, and Regent St which is not.  As the speed profiles are similar it is clear that the data was not influenced by vehicular traffic. However, for some devices the detected distance is less than the actual one due to low reporting frequency.  The team expected that the resulting average speed would be overestimated. To eliminate this effect, they did not consider higher (and implausible) values. When the tails were  excluded, the profiles show a normal distribution with an average speed of 1.2 meters/sec.Pedestrian speeds

Rendering pedestrian simulation with Virtual Reality

The simulation also includes vehicular movements obtained from dynamic traffic modeling of the area.VR Oxford Street visualization

Behind the scenes

To implement their solution, the Atkins team deployed Accuware’s WiFi Location Monitor, a system designed to passively detect and locate active WiFi devices, such as cell phones and tablets.

Using WiFi Location Monitor requires deploying WiFi “nodes“, which are WiFi routers set on listening mode. Nodes detect the presence and signal strength of active WiFi devices nearby, uploading their data to a cloud-based server.  The server estimates the location of each WiFi device from the signals collected by multiple nodes.  Each device is identified by its WiFi MAC address. Note that no personally identifiable information is ever collected.  All collected data is truly anonymous.  Actual location of each device is estimated within a 3-meter radius of its actual location. which is ideal for urban use surveys.

Deep Dive into Data Visualization

In an article dating from last May, The Economist argued that data was “the world’s most valuable resource.” We could not agree more. Gathering data is not enough. Finding appropriate ways to visualise it and communicate it is just as crucial.

Our partners at Wezit recently attended the Museum Computer Network Conference in Pittsburgh…MCN 2017 in Pittsburgh

… and garnered a few observations from the “Beyond the Graphing Calculator” talk.   Here is what Wezit’s Alexia Casanova shared with us.

We all take information in differently

In her “#musedata is cool” presentation, Angie Judge from DEXIBIT reminded us all that we all like to take in information in different ways. Some people respond better to raw numbers, others prefer visual representations, creative propositions, stories or text. It is essential to adapt to whoever you are trying to communicate this information to. Good data visualization should help your team make informed strategic decisions. When paired with geolocation technology, it gives you a better understanding of how visitors are progressing through space and how you can improve the visiting experience based on their habits.

Data visualization is not dumbing down information

Elizabeth Bollwerk is an Archaeological analyst at the Digital Archaeological Archive of Comparative Slavery (DAACS), an initiative of the Thomas Jefferson Foundation, which happens to share all of the data regarding their archaeological collection on their website. DAACS logo In her presentation, she stressed the need to “[portray] the data meaning accurately and ethically.” She explains that presenting data in a creative way shouldn’t compromise the accuracy of the information that is being shared. Good data visualization should help you understand information quickly but also allow you to make informed strategic decisions.

The future of data visualization is bright

Jeff Steward from the Harvard Art Museums presented a series of extremely creative data visualisations including a representation of the whole museum’s collection in the form of a solar system. Harvard Art Museums“Can data be immersive?” he asked, “what if I could walk through data with virtual reality?” This would certainly be a wonderful way to weave data into a tangible and playful experience.

Jeff Steward: Applying astronomical metaphors to render the collection as a series of solar systems.

Angie Judge described what the future of data visualization looks like for DEXIBIT: machine learning models predicting what tomorrow’s data will be and friendly chat bots answering decision-makers’ questions based on the data collected. Exciting, isn’t it?

Practical SLAM for IoT is here

This is about our latest product: a computer vision-based indoor positioning system (IPS) capable of delivering a mobile device’s location with high accuracy without need for infrastructure and minimal site preparation.VPS heatmap

We asked our CEO to walk us through a demonstration of the new product.  He happily agreed.  This is what happened.

Dragonfly’s Capabilities

Accuware Dragonfly (formerly Visual Positioning System) is a SLAM-based system.  In brief: Dragonfly uses a camera to perform Simultaneous Localization And Mapping (SLAM), a technique described as “… the computational problem of constructing or updating a map of an unknown environment while simultaneously keeping track of an agent’s location within it “.  The agent in question is an autonomous mobile device, most likely a robot that moves through physical space carrying a camera hooked up to a computer.

A minimal site setup is required:  at least 3 markers must be placed throughout the site.  They encode specific location coordinates, and are used by Dragonfly to initialize its position. Markers are easily generated on a regular printer.

Dragonfly Marker

Dragonfly was designed to be thrifty in its use of available resources.  As expected, the device’s camera is the main drain of battery power, while the computational footprint, available as an SDK, has been optimized to run efficiently on a regular smartphone, and is available on other platforms.

Dragonfly uses the device’s camera to analyze its surroundings, map the environment around it, and determine its location in reference to its physical context. This data can be shared with an external system (ex. a server) to track the device’s location over time.

Putting the demo together

Our first challenge was finding a suitable autonomous mobile robot fitted with computer and camera, to run the demo.  VPS robot setupAfter some deliberation, we realized that our faithful office iRobot is an autonomous mobile platform, while a regular smartphone could provide the requisite computational power plus video camera.  A smartphone car bracket mounted on top of the iRobot completed the setup for an Android Nexus X5.VPS installing the smartphone

We installed the test mobile app on the Nexus X5.  It integrates with the Dragonfly 2.0 SDK and uses available WiFi and/or 3G or LTE to upload data to our cloud-based server, whose dashboard displays the phone’s real-time location on the floor plan we uploaded.

The advantage of this setup is that it can be easily replicated by anyone interested in testing this product to learn how it behaves, with the convenience of using everyday items.  Note also that household robots like the iRobot are designed to discover and avoid obstacles in the physical environment where they move.  This matches the practical use cases we envision.VPS demo robot

Here is the demonstration

The video gives us the highlights of this experience.  Mount the smartphone on the robot and start it.  As the robot moves about, Dragonfly maps the environment while reporting the sequence of locations reached. The server displays these on the dashboard as a moving dot.

Note the spaghetti diagram depicting the robot’s entire trajectory:

VPS spaghetti diagram

And the heatmap, which highlights the physical areas covered by the robot.  Both diagrams built using location data collected through the test. Dragonfly Heatmap

Applications Envisioned

What applications do we envision for this product?  Here’s a short list:

  • Guiding pick-and-place autonomous mobile robots in warehousesAutonomous mobile robot
  • Mobile industrial robots in “Smart Manufacturing” environments
  • Roaming security robots patrolling buildings, parking lots and garages

In other words, physical location, as provided by Dragonfly 2.0 can be a key ingredient for IoT applications in industrial settings.  It is the “location sensor” in environments variously referred to as: “Industry 4.0”, “Industrial Internet”, “Connected Enterprise”, “Smart Manufacturing”, “Smart Factory”, “Manufacturing 4.0”, “Internet of Everything” or “IoT for Manufacturing”.

Rounding it up

Accuware is a technology-driven company.  It is in our DNA.  We value technology with practical uses in mind.  We develop products that leverage different technologies, all focused on providing physical location in the real world.

Dragonfly is today’s accomplishment.  The R&D effort took many months.  The product launch follows the model from previous releases.  Provide interested parties with a chance to evaluate the new product in their environment.  Our Tech Support group will assist committed users to ensure their success.  Our Partners network will come up to speed on the new release.  Case studies will follow.

We are thrilled by the possibilities of this product.  Do you want to try this system in your environment?  Contact us for details.

Incidentally, the heatmap helped us visualize the iRobot’s coverage, so we redirected it until the office had been thoroughly swept clean and looked pristine.  We have the data to prove it.   Now, that’s quality control. VPS CEO introduction

Digital innovation in Spain’s retail sector

Based in Barcelona, Spain, Be Retail is a provider of innovative solutions in Spain’s retail market.  Part of the Be Motion group, which focuses on online marketing, Be Retail delivers solutions for bricks-and-mortar clients that combine mobile, location and analytics.  Their innovation enables new practices and methods.

Clothing store window

As we well know, retail is a fiercely competitive space that over the past few years has been transitioning from simple bricks-and-mortar to a new era that merges the physical world, online and mobile.  Responses to these challenges have included omnichannel strategies with a renewed awareness on the power of mobile, location-awareness and analytics.

Adoption of new ways of shopping throughout the world has been uneven. Price-Waterhouse Coopers’ (PwC) Total Retail 2017 describes the retail market worldwide, focusing on the Spanish market as an example to illustrate a societal transition where online shopping is gradually but firmly gaining ground on bricks-and-mortar. Major retailers, both domestic and foreign (European and American) are changing their game plans, responding with new approaches, technology and methods. BeRetail has played a key role delivering innovation into this market.  Here are some of their projects.

Major Supermarket Chain

Taking advantage of the ubiquitous mobile devices, a major chain of supermarkets is deploying an array of in-store solutions targeting their customers and their operations:

Proximity Marketing. A customer walks by a specific area of the store and receives information about an item of interest. Either a promotional offer or simply product information about an item available nearby. The information is always contextual: it may take into account the customers’ interest, the time of day, and the location inside the store: a gentle reminder that their object of interest is just down the aisle or around the corner.  This is the classical application of iBeacons paired up with a custom app.  And it is made possible by having the customer install the store’s app on their phone and, ideally, to share their shopping preferences.

Business intelligence. Through analytics, merchandising specialists and store managers can gain insights by analyzing customer behavior inside the store: Where do customers go? How long do they linger?  What are the preferred paths throughout the various sections?   How do path, speed and dwell time change throughout the day?  On different days of the week?  Does anyone linger in front of endcaps?  How many customers spend time at brand-specific exhibits?  How long are the checkout lines at various time of the day?
Father and daughter at the supermarket

These insights, and many others are possible by tracking customers’ movements throughout the store.  For instance, at a supermarket, shopping carts and baskets can be fitted with electronic tags that broadcast their location inside the store. That makes possible tracing the whereabouts of customers moving through physical space, which enables generating heat maps and traces to illustrate people’s movements over time.  Note that personal privacy is never compromised by this technique, as no personally identifiable information is ever collected.

Online ordering with in-store pickup services. Supermarket produce sectionSupermarkets have implemented systems that enable customers to order online or via their smartphones the items in their shopping list, and have store employees gather the items, bag the order, and have it ready for pick up when the customer shows up. This can be especially convenient for hurried parents driving home from work, with children in the back seat, just picked up from school or daycare.

The store can radically increase their employees’s efficiency by using a system that analyzes the shopping lists and plots the most efficient route throughout the store so that the employee collecting the order can be guided from item to item, without missing anything.   An indoor navigation system enables the step-by-step guidance required.  Just picture a tablet attached to the shopping cart, guiding the employee, displaying the route through the shortest path.  Such a system requires a database that accurately maps items and their locations throughout the store.

Auto Mechanic Shop’s performance

A chain of auto mechanic shops that serve insurance agencies, decided to use actual performance data to differentiate itself from the competition.  Customers could now have answers to performance questions: How long does it take for a vehicle to be serviced for a given problem?  What is the estimated service time per problem type?   How many vehicles are being serviced? At what step in the service chain is a given vehicle?  What’s the estimated service completion time for each vehicle?  What’s the shop’s performance rating?

Keys at auto shop

The company decided to deploy a solution to measure the efficiency and performance of its shops. The solution tracked the location of each vehicle throughout the service stages at the shop.  An indoor location tracking tag was attached to each vehicle.  Each vehicle’s position within the shop was tracked automatically throughout the service process and its location was made available both through an online dashboard for customers to access, and through a mobile app, which also provided status alerts.

The system significantly increased the perception of transparency. No longer were customers in the dark about how service to their vehicle was progressing.  Now they could actually check where their vehicle was in the chain and get its status. There is now a performance rating.

Behind the scenes

BeRetail logoIt takes an innovative solution provider like BeRetail to bring complex applications like these to life, addressing real business needs with technology.  And it takes technology partners to provide some of the required building blocks, reducing time to market and risk.

BeRetail bridges the gap between customers’ needs and technology. Accuware provides its location platform and support to ensure a successful implementation.

Using Accuware’s products, BeRetail has access to functionality such as:

  • Proximity applications were implemented using a standard iBeacons infrastructure: Bluetooth Low Energy (BLE) iBeacons (hardware) deployed throughout a venue, to trigger branded mobile apps running on customers’ phones and tablets. When actual location, rather than mere proximity is required, Accuware Indoor Location may be the right tool.
  • Indoor tracking of objects (ex. shopping carts, cars) was enabled by Accuware Bluetooth Beacon Tracker. This product uses small form-factor BLE beacons (ex. iBeacons) attached to objects, whose signals are triangulated by a set of beacon sensors (hardware) deployed throughout the venue.  Note that tracking people may also be possible with this system.
  • Indoor navigation was implemented leveraging Accuware Indoor Navigation, which relies on apps running on tablets or smartphones that sense ambient WiFi signals augmented by signals from device sensors like gyroscopes and accelerators.

Experience shows that no single technology works best for all location-aware applications.  It depends.  That’s why solution providers like BeRetail can partner with platform providers that combine the latest technologies with worldwide coverage and support.

It is a win for everyone; especially for our common customers.

Nantes Museum of Art reborn

On June 23, 2017, the Musée d’Arts de Nantes reopened after an 88+ million Euros, six-year long renovation.  The beautiful main building was renovated and expanded.  A new building, the Cube, was dedicated to contemporary art, and a large inner space was opened for public exhibits.  In addition, digital technologies were deployed throughout the museum to make it all accessible, creating unforgettable new experiences for all visitors.Musée d'Arts de Nantes

Created in 1801 as a provincial museum, the Fine Arts Museum of Nantes, now named Musée d’Arts de Nantes, is the largest and most important institution in France’s Loire region.  Its collections contain works from all major French and European art movements, placing them among the largest public collections alongside the six largest notable Museums of Fine Arts: those of Grenoble, Lille, Lyon, Montpellier and Rouen.


The physical renovation was commissioned to the British architectural firm Stanton Williams, and the digital implementation was entrusted to the French digital agency Mazedia.  The results were stunning.
Musée d'Arts de Nantes

Stanton Williams delivered a magnificent new and expanded physical space, transforming the 19th century complex into an “urban quarter” that encompasses the original building (“le palais”), the chapel (“l’oratoire”), the garden area now open for exhibits, and a new building. the Cube, destined to house contemporary art.  Exhibit space was enlarged by almost a third, enabling 900 new pieces of the 13,000 collection to be available for visitors.

The digital transformation was equally remarkable. Mazedia deployed Wezit, a transmedia storytelling platform for implementing interactive programs at cultural institutions using multiple media formats.  At Nantes three Wezit-enabled attractions were deployed: the Ma Visite mobile app for visitors’ smartphones and tablets, interactive kiosks and the “Under the magnifying glass” stations.


There were twin objectives for the digital transformation: enabling the content curation desired by the museum and creating a superb visitor experience.Visitors experience

Curation enabled presenting the content so as to highlight the artwork as conceived by museum curators.

Visitor experience required additional work: a key requirement was for visitors to either be able to create their own tour and operate autonomously, or to take advantage of the predefined tours designed around specific topics.

Since the renovated museum complex is quite large, passageways have been created between buildings that were formerly not present, and some spaces are now used differently than they were before the renovation. As a result, one of the museum’s big challenges was helping visitors find their way easily inside the new, larger space.  Location-awareness, both of artwork and for visitors, became a key concern to address.  Indoor location helped tackle these problems.

Ma Visite mobile app

Ma Visite (“My visit”) is an app available for both iOS and Android devices. Ma Visite mobile app It provides access to key information and functions:

  • the list of all curated museum tours, which encompass the museum’s collections, its architecture, works grouped by time period, or tours such as “looking for love” and the “literary tour”
  • tours for families
  • the “must-see” exhibits
  • the ability for visitors to build custom tours based on their personal interests, and this is possible to do even before reaching the museum grounds
  • special event announcements
  • indoor navigation, for visitors to find their way throughout this vast physical space.

Especially notable are the “must-see” exhibits (“Oeuvres incountournables“), the masterpieces that set this museum apart.  Here is a peek at the user’s experience:


The museum is large, spanning multiple levels over different buildings.
Visitor at a kisok
Complementing the Ma Visite app, the kiosks give visitors the ability to instantly find their location, and search for exhibits of their interest with the convenience of a larger screen.

All artifacts can be found through these kiosks. This way visitors can learn how to locate the specific artworks they wish to see.

Artwork search with location

“Under the magnifying glass” stations

Strategically placed in front of the major exhibits, these stations give visitors the ability to explore notable artwork in detail.
"Oeuvre a la loupe"

"Oeuvre a la loupe"The stations provide the “magnifying glass” (“Œuvre à la loupe”) that enables visitors to delve deeper into the artist, history and significance of these exhibits.

Interestingly, young visitors, accompanied by their parents, are instantly fascinated by these digital devices, rapidly mastering the ability to learn through them.

Le Deluge a la loupe

Behind the scenes

What made the digital magic possible?  Here is how it happened.

Mazedia created the graphics and designed interfaces for the various devices: the website, the mobile app, the kiosks, and the “magnifying glass” stations.  All of them are linked to Wezit, the transmedia platform that enables structuring and  personalizing the digital content published across devices.  Visitors, in particular, may use a variety of devices, such as smartphones, tablets, kiosks or the website portal.  Also, Wezit enables museum curators and administrators to manage the digital content.

Beacons placementA key element of the information displayed to visitors is their location and the location of the artwork they may see during their visit.  Artwork location is displayed as part of search results.

Technically, there are two different ways of providing location. One is using proximity, as in “I’m standing near ‘Le Déluge’ exhibit”.  There is also use for actual geographic coordinates.  For instance: “I’m on the 2nd floor, in the 3rd gallery, near the center of the room”.  This second version delivers coordinates: latitude, longitude and level.

iBeacons were deployed throughout the museum to provide location. These Bluetooth beacons deliver both proximity to specific spots, as the standard iBeacon functionality delivers, as well as indoor location using Accuware’s Indoor Navigation product, which first maps the location of each and every iBeacon, and then delivers coordinates to mobile apps based on the user’s real time location.

With location functionality firmly embedded in Ma Visite, visitors were able to pinpoint their current location and get guidance to locate and see any artwork of their choosing, combining autonomy and flexibility for a great experience.

Early feedback from digital infrastructure users has been very positive.  Children, in particular, were wildly enthusiastic in their embrace of new technology, which instantly multiplied their interest in exploring and learning.  And that is music to the ears of all those who contributed to this remarkable transformation.Wezit at Musee d'Arts de Nantes

Accuware at ISC West 2017

Our latest solutions for 3-D positioning and video analysis

The Accuware Team will be at the International Security Conference & Exposition, ISC West,  from April 5th to the 7th.ISC West 2017 bannerAt our booth we will demonstrate the latest features of products designed to deliver high reliability and location accuracy in a variety of applications. Our latest offerings include Video Positioning System (VPS) code-named Dragonfly, and Video Location Monitor.  These products expand Accuware’s portfolio, which harness multiple technologies to provide solutions for locating, tracking and monitoring people and mobile assets in the physical world.


An early version of Dragonfly (formerly VPS) made its debut at CTIA 2016, the main trade show for the wireless industry.  At that time, Dragonfly was able to estimate the location of a camera-equipped mobile device in 3-dimensions, with an accuracy of just a few inches. It determined its position by decoding visual markers placed around a venue.  The coordinates it produces include latitude, longitude, height off the floor and level (ex. 1st floor, 2nd floor, etc.), which makes it appealing for applications of autonomous mobile robots and drones.

The latest Dragonfly has learned new tricks: by first performing a “visual fingerprinting” of a venue with a device’s camera, Dragonfly can now take a snapshot anywhere around the venue and determine its location by interpolating that image into the database of “ambient visual fingerprints”.  The new system is also self-optimizing, in that it continues “learning” the environment, causing its resolution and location accuracy to improve over time.

This video shows a demonstration of the new Dragonfly functionality as it would be seen when run on a drone:

Sentinel (formerly Video Tracker) is a new tool that delivers useful features for intelligent video analysis.  

Imagine a CCTV system displaying a video feed on multiple screens, under the watchful gaze of  several human operators.  Now imagine those operators suddenly wondering whether a person currently visible on the screen has appeared before.  Is that person currently on camera 3 the same one we saw on camera 6 about 20 minutes ago?  Have we seen this person earlier?  Perhaps earlier this morning?  At what time?  Was that same person present multiple times? When and where?

Now picture the CCTV feed been analyzed in real-time: people visible on the screen are being identified by their appearance, including body bulk, height and clothing color (face recognition is not used). Video Tracker detects individuals
Imagine a database containing small snippets of video collected over time, with annotations of who is visible on each snippet, when it was taken and where.  Incidentally, these snippets are referred to as “tracklets”, meaning “portions of a track”, a “track” being the sequence of physical positions of a given subject as it moves through physical space over time.

Once a person’s appearance is uniquely identified and categorized, this enables tracking the movement of that specific individual across multiple camera views over time.  In other words, classifying tracklets in real-time provides the ability to track individuals moving through a monitored venue over time.  Most importantly, the tracklets database enables visual search.

Visual search works as follows: knowing a specific individual’s appearance, it is possible to search the tracklets database to learn when and where that individual has appeared on screen over time.  Visual search is one of Sentinel’s key features.   Here is a demonstration.

As shown in the video, other key features of Sentinel include the ability to perform traffic analysis, definition of geofences, and the visualization of the varying density of people present in a monitored area over a period of time.

Regarding Sentinel’s search feature, it is important to emphasize that the system does not use facial recognition, given the impracticality of this technology on relatively small and low-resolution video footage. Privacy considerations should take into account that Sentinel’s features enhance video surveillance mechanisms already in place.
