In the second version of my physical-cube-interface prototype you can not see the video stream. I tried to make the tracking more stable and also implemented some of my initial ideas for viewing actual radiology data. This is still a very early prototype but I have the feeling that I am on the right track here. While playing around with the prototype I become more familiar with the advantages and problems. It already feels really natural to view a 3D model. But I think the other ideas I’ve implemented (pressure sensor, move cube left/right to change transparency) need some more consideration. At this stage there is too much things happening at the same time.
