I think situations where the camera (or IR sensors) pick up user gestures are an important area (we will see a lot of that in the future) and could (or should) be included. Both in motion actuation and in the processing of the video input stream, the user moves to communicate an intent, and may not be able to, so alternatives are needed. I’m just saying it’s worthwhile discussing where to draw the line. > On 11 Oct 2017, at 07:56, Patrick H. Lauke <redux@splintered.co.uk> wrote: > > On 11/10/2017 06:52, Patrick H.
