Demonstrating new technologies requires always lots of money or imagination. It is extremely hard to visualize, for example, wireless network coverage, soundscape or interaction between people without actually building the space for it and taking people there in person. What if we would have a virtual showroom where these things could be visualized in metaverse-like environments and test different scenarios? This virtual showroom could be set up in different layouts and modified depending on the customer’s needs and experienced in an immersive way. In this project we want to create demonstrations of showrooms that visualize something invisible (such as wireless network coverage or acoustics). What kind of technologies (such as WebXR) should be used when creating a virtual showroom? How should the invisible elements be visualized so that the user can play around with different kinds of layouts and test different scenarios? What would be the most dazzling examples to demonstrate in the virtual showroom? This project is about highlighting what could be done with a proper virtual showroom that goes beyond just showcasing cool 3D models of the physical products. If you are interested in VR or WebXR, join the project and let’s start building cool environments!
