Stockx IT is proud to have worked with Kunstmaan | Accenture Interactive to make sure Memorial Day in Belgium still took place in 2020.

For nearly 100 years, the American Overseas Memorial Day Association in Belgium has ensured that public ceremonies are held to honor America’s fallen. Yet with current regulations prohibiting public gatherings, more than 20 Memorial Day ceremonies in Belgium were cancelled this year, most for the first time since 1923. Resolute that COVID-19 would not get in the way of the 75th anniversary of the Battle of the Bulge and the end of WWII, the Association turned to interactive technology to remember America’s fallen. More than 3,700 people attended the interactive ceremony.

This year’s public Memorial Day ceremony took place as a unique live and interactive “.commemoration” on Monday, May 25, 2020 at 18.00 (GMT+1) on a dedicated platform: www.memorialdayonline.com. U.S. Ambassador Ronald Gidwitz opened the ceremony live from Belgium. Additional speakers included Belgian Prime Minister Sophie Wilmès, General John Love, United States Military Representative to NATO, mayors, WWII veterans, and many others.

The online occasion developed by Accenture Interactive Belux and Stockx IT is unique for its combined livestream and social interaction experience. The public were not only able to watch the event live but could be a part of it in real time. As the ceremony unfolded, viewers could choose to watch the livestream alone, or to invite up to eight people in a virtual ‘seating area’ in order to experience the ceremony together as they would at the actual events. More than 3,700 people attended the ceremony.

Participants were also invited to lay a virtual rose in honor of all men and women who have died in military service for the United States. Of the more than 500,000 American service members who died during World Wars I and II, more than 14,000 are buried in Belgium.

CityGlow - Marche-en-Famenne

• Clients: Kunstmaan, Accenture Interactive, engie, Marche-en-Famenne
• Date: March 2019 - May 2019
• Service: Lead and Sole Mobile Developer (Flutter)
• Where to find it: Marche-en-Famenne Tourist Centre (French), Engie website (Dutch),

Project Achievements:

• First tourist app to combine Bluetooth and LiFi for optimal localisation and power usage.
• Fully offline app using Lifi for unlocking content.
• Syncable with Firebase backend and Sentry environment for content input, analytics and bug/crash reporting.

For Engie, a client of Kunstmaan | Accenture Interactive, Stockx IT built a unique mobile app for dedicated Android tablets in Flutter.

The application, CityGlow, allows for data to be transferred much faster and safer via LiFi than through regular wifi. As a pilot, it will be used in the cultural scene to give people a unique and interactive experience.

The procedure is simple: visitors use the CityGlow tablet to navigate throughout the city, where Engie installed a series of LiFi lamps that pick up on the tablet’s signal and automatically turn on. When a visitor walks up to a statue, the light from the Lifi lamp automatically gets recognised by the tablet. In a split second, the app unlocks a certain piece of content: introductory text notes giving the visitor insights about the artist, images of his workshop or of other related works, videos with artist interviews and even games.

Feel free to visit Marche-en-Famenne at any time to experience CityGlow for yourself!

• Geofencing for awarding points near the azuleo showroom.

Together with Kunstmaan | Accenture Interactive, a new mobile app was created for azuleo, subsidiary of Steylaerts. Azuleo was looking for a way to increase loyalty of partners who install tiles and products in the homes of consumers. In addition to existing initiatives, azuleo wanted to give away champaign to its partners in a fun and engaging way at the end of the year.

Together with Kunstmaan the concept was created to use a mobile app as a way to collect points when partners visit or pass by the showroom. Points are also rewarded for each sale and for events such as birthdays.

We made this happen using the latest innovations in mobile technology including Flutter and Firebase. Part of our solution includes geofencing to automatically reward points to partners who happen to pass by or visit the showroom.

The app was successfully launched with a high adoption rate at an azuleo partner event. In December the first rewards period will end, and auzelo’s partners will be able to enjoy the holidays with champaign. Cheers!

• Date: April 2018 - May 2018
• Service: Senior Mobile Developer (Flutter), Backend Development (Firebase)
• Download: Google Play, App Store

Project Details:

• Developed with Flutter, Google's new mobile UI framework.
• Cross-platform, shared codebase for Android and iOS.
• Serverless architecture with Firebase backend.
• Bluetooth beacons ranging for locating mobile devices inside of the Kunstmaan offices.

As a first experiment with Flutter, Google's new mobile UI framework, an internal app for the Kunstmaan | Accenture Interactive offices was developed. It includes Slack sign-in, user generated content, and localisation features using Bluetooth beacons.

The serverless architecture was achieved with Firebase, using Cloud Firestore as the database model. All data from Firestore is streamed to the device, resulting in constant real-time updates. Firebase Authentication is used together with Slack sign-in, Firebase Storage for managing user-generated content such as profile pictures and kudo's, and Firebase Functions (together with Firebase Cloud Messaging) are used for triggering push notifications and syncing our user database with Slack. Lastly, Firebase Analytics are implemented as well.

Implementing this internal app in Flutter successfully has provided Kunstmaan | Accenture Interactive with the confidence to start providing Flutter as an option for mobile apps to clients.

Custom LED Accenture Logo powered by Unity

---

• Clients: Kunstmaan, Accenture Interactive
• Date: November 2017
• Service: Senior Unity Developer (built software, assisted on hardware)

Project Achievements:

• Custom-built LED screen with over 3200 LEDs.
• Interactive animation via 5 ultrasonic range sensors.
• Software powered by Unity to allow rapid iteration and multiple animation scenes.

When Kunstmaan became a part of Accenture Interactive, a challenge was set to create a new immersive and interactive Accenture logo in the entrance hall of the Kunstmaan office in Leuven, to replace the wooden Kunstmaan logo. Instead of going for an off-the-shelf solution, it was decided to completely build it in-house. The hardware consists of 3000+ LEDs, 5 ultrasonic range sensors, and 5 USB-ISS communication modules (4 for the LED screen, 1 for the sensors). The software is built in Unity for rapid iteration and allows easy switching between several scenes.

For this project I've built the complete Unity project singlehandedly, and assisted with building the hardware.

During my time at the award-winning Boss Alien studio, where I started as a Graduate Programmer, I've been a part of the CSR Racing developer team. As both a Gameplay Programmer and Platform Specialist (Android), most of my time was spent on adding new features and improvements to the CSR franchise games, whilst making sure our games utilised the latest features provided by the Google Play Services or the Android platform in general.

Several Android specific changes that I did (moving to a Gradle pipeline, integrating Google Play Games Video Recording,...) were also ported to CSR Racing 2.

In the last few months of CSR Racing's development I was the sole engineer on the product, working together with Zynga and several 3rd parties to make sure all external SDK's were as stable as possible for the final update of the product.

XBox H2O

• Client: Hasselt University - UIST 2013 Student Innovation Contest
• Date: September 2013
• Service: Implemented the 2D game engine and gameplay in C++/Qt
  (xbox-controller and pumpspark integration by Ben Jorissen, OpenCV integration by Raf Ramakers)

Project Achievements:

• 2nd People's Choice award at UIST 2013 Student Innovation Contest.
• Presented at UIST 2013 in St. Andrews, UK.
• Unique combination of hardware and software.

Our team from Hasselt University consisting of Ben Jorissen, Raf Ramakers, and myself won the 2nd People's Choice award at the UIST 2013 Student Innovation Contest. Each team was given a state-of-the-art hardware, and are challenged to come up with interactions for the device. In 2013, the provided hardware was a kit containing 8 small waterpumps. After brainstorming we came up with an idea for a game, where you can control a ball using fluid dynamics and the 8 pumps.

As visualized in the picture above, we put a pump at each side, and six at he bottom of the setup. The ball floats on the waterjet propelled from the bottom pumps. The ball can be moved between pumps by activating the side pumps to splice the waterjets as seen in the image below. To integrate a game we used a projector and webcam, to respectively project and capture the scene. The game is controlled by an xbox-controller, hence the name of the project.

• Client: Hasselt University - ACM SIGSPATIAL 2014
• Date: November 2014
• Awards: Alcatel-Lucent Bell MSc Thesis Award 2014
• Service: Data capturing and prototype client implemented using the Android SDK
  Data analytics tool written using the Windows Store SDK

Project Achievements:

• Research awarded with Alcatel Lucent-Bell MSc Thesis Award 2014.
• Presented as short paper at ACM SIGSPATIAL 2014 in Dallas, Texas, USA.
• SubwayPS proved to be substantially better than baseline approaches.
• Proof of concept mobile application for unique smartphone positioning algorithm.

Thanks to rapid advances in technologies like GPS and Wi-Fi positioning, smartphone users are able to determine their location almost everywhere they go. This is not true, however, of people who are traveling in underground public transportation networks, one of the few types of high-traffic areas where smartphones do not have access to accurate position information.

In comes SubwayPS, an accelerometer-based positioning technique that allows smartphones to determine their location substantially better than baseline approaches, even deep beneath city streets. I've highlighted several immediate applications of positioning in subway networks in domains ranging from mobile advertising to mobile maps and present MetroNavigator, a proof-of-concept smartphone and smartwatch app that notifies users of upcoming points-of-interest and alerts them when it is time to get ready to exit the train.
