Touchless interaction in VR is moving forward. With players like gestigon, Leap Motion and Sony the necessary software tools are progressing. Now, all start looking at AR ... and new challenges arise: As in AR you can see your surrounding and your hands, any tracking needs to be 110 percent accurate. But how can this work with a HMD that might be taken on and off, that will not allow a new calibration every time, where the eyes and the 3D cameras have different angles? Even at the CES none of the big players demoed a solution for this. During this session the CEO of gestigon, a market leader in touchless AR and VR interaction solutions, will elaborate on these challenges and give an inside view why even the big fish like Microsoft with their Hololense have not solved the touchless AR interaction paradigms.
