When I did my vocational internship at the Innovation Center department at the Swedish unemployment office (Arbetsförmedlingen), our team of 3-4 developers including me, did three VR tech demos and one prototype of Platsbanken – their job advertisement platform. The goal was to try something vastly different, to explore and push the boundaries of immersive interaction with the platform.
This is the prototype – an interactive object that can be placed in any virtual environment. When you grab the object, an interface unfolds and you can start interacting with it. This type of thing could also work as a digital artifact in MR – a virtual object you can place in you actual physical bookshelf, and interact with as long as you have your MR glasses on.
