ABSTRACT:
This invention relates to the untethered multiple user interaction of large information displays using laser pointers coordinated with voice commands. A projection system projects application windows onto a large information display. One or more users may command their respective window applications using laser pointers and/or voice commands. A registration program assigns a unique identification to each user that associates a particular users's voice and a particular laser pointer pattern chosen by that user, with that particular user. Cameras scan the information display and process the composite of the application windows and any laser pointer images thereon. A sequence of computer decisions checks each laser pointer command so as to correctly associate respective users with their commands and application windows. Users may speak voice commands. The system will then perform speech recognition of the user's voice command. If the command is recognized, the system performs the speech-recognized command as a window operation.
