I work with Aframe, AR.js and Three.js for developing a range of POCs and demo applications providing AR experiences for various use cases. I have also developed in Unity for Hololens for educational purposes (STEM education).
Bellow is a Web AR demo for Cosmote stores in order to engage customers while shopping. The demo bellow provides information on offers through AR markers displayed in devices' screens. It also containes a game whereby the user collects virtual objects and participates in a lotery if all virtual objects are found
Something like pocemon go ;) The final version is currently developed in ARCore for Android and IOs having similar functionalities: Customers will be able to view information on personalized offers on their screens, and participate into AR games to win products.
Scan the QRs to open the game web app. Then scan some of the markers bellow ... and enjoy :)
