To create an immersive experience both, AR and VR, require a natural and easy way of control and interaction. Todays devices are either fairly passiv (like the Cardboard or Glyph) or require an additional controler hardware (like the HTC Vive). Even if these controllers work really well, they remain bulky, require abstract interaction and power. --- The easier solution to AR and VR control would be using our hands: always available and always on. Plus, to create a truely immersive experience we need to see our hands and fingers in the virtual scene. Moritz is going to elaborate on the opportunities to create the most natural user interaction in AR and VR.
