Abstract: This invention provides a method for registering and enrolling multiple users in a interactive information display systems where the untethered multiple users interact with large information displays using laser pointers coordinated with voice commands. A registration program assigns a unique identification to each user that associates a particular user's voice and a particular laser pointer pattern chosen by that user, with that particular user. 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.

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.

Abstract: In a system that projects application windows onto an information display, one or more users command their respective window applications using laser pointers and/or voice. A registration program assigns a unique identification to each user and associates that user's voice and a particular laser pointer pattern. A sequence of computer decisions checks each laser pointer command so as to correctly associate respective users with their commands and their application windows. Users may speak voice commands. The invention performs speech recognition of the user's voice command. If the command is recognized, the invention performs the speech-recognized command as a window operation.

Abstract: One or more users may command their respective window applications on an interactive display networked to client computers using laser pointers and/or voice commands. Users' voices are associated with a particular laser pointer pattern. A sequence of computer decisions checks each laser pointer command so as to correctly associate respective users with their commands and application windows. The invention performs speech recognition of the user's voice command. If the command is recognized, the invention performs the speech-recognized command as a window operation. The location of all unique light patterns is broadcast to all networked client computers.

Abstract: Interaction with a display occurs. A light point is transmitted towards the display. A mode of operation of the light point is established based on timing associated with illumination of the light point.
