Dream Beamer is a solution that keeps projector's light away from a presenter.
The system keeps track of the presenter and casts shadow on him whenever he/she is in the beam. Therefore the presenter is not blinded and there is no distorted image on his/her body.
Dream Beamer uses a pair of high speed cameras or 3d sensor for person tracking and a special software which is installed on the presentor's PC for data processing and shadowing.
