Abstract
The optical auxiliary input arrangement for an optical system projecting computer generated images includes an image processing unit and communication interface for detecting the speed at which two high intensity auxiliary light images flash onto the projected computer image, to interpret the images as a mouse double click feature. The optical auxiliary input arrangement accurately and reliably discriminates between user generated double click information without the need of the user being so steady of hand as to cause the auxiliary light information beam to illuminate the same precise location on the viewing surface during the double click operation. The image processing unit and communication interface cooperate together to permit both a low speed mouse and the high speed light generating device to communicate with the system.
