beeing rather a proof of concept rather then a fully functional prototype this thing shows how relatively easy it is to build a picoprojector / camera plattform for the shoulder.
The possible applications for this device range from video art (projector men doing shows) and gaming (dressing up in magic armor by projecting the items animation on the user) to user interfaces (tracking geststure input and projecting accordingly, like a powerpoint2go machine).

this video shows the basic controll for this attjector moving on one axis. youtu.be/nLFocUo0tfU
this video is from early development phase, when I was trying to use geared motors instead of servos for moving the payload. youtu.be/nLFocUo0tfU
