Abstract: A presentation control system and method facilitates the interaction between a user and a presentation device. The user generates tangible sensible identification devices, which are linked to items to be displayed in a presentation. In use, the user places the tangible sensible identification-carrying device, in the sensible area of an identification sensing device. The identification sensing device reads a presentation element identification from the identification-carrying device and determines a presentation element identified by the presentation element identification. The presentation element is then displayed via a presentation display device.

Abstract: Tangible computing is the manipulation of real, physical objects to instruct and control computers. Computer programs can be created by manipulating physical objects that represent program language elements of a program or programming language. A tangible computing system calls for observation by a computer of a real, three-dimensional work space, where each physical object can be assigned a program language element. Assignment of attributes to, and/or movement of each real physical object results in the creation of a new program component. In this manner, a user can manipulate real, physical objects to create programs. Thus, the real world itself becomes a human-computer interface that allows a user to create programs and control digital processes.

Abstract: A computer-supported collaborative work environment allows for computer-mediated, multi-modal, asynchronous meetings in a virtual space that enables, recording, reviewing and augmenting meetings that take place in the virtual environment. Meeting participants interact via avatars, i.e., graphical representations of the participants, in a place-based, multi-dimensional graphical environment. Meeting sessions are captured for future replay and augmentation in a multi-modal document. The system utilizes multiple "tracks" in the multi-modal document, such as text discussion, audio commands, graphics, and documents, which are combined into the multi-modal document to preserve a recording of the meeting for future participants. The multi-modal document of this meeting can then be replayed and augmented by future participants ad infinitum to create a single, synchronous meeting.
