Abstract: Complex collaboration or decision support applications perform complex design or planning tasks, often with the input of large groups of people over long periods of time. The combination of time and complexity can often obscure past actions, making it difficult to remember the factors that influenced earlier stages in the planning task. This is especially true if the task involves many people and different people work at different times. The application state navigation system provides an application-independent mechanism that allows operators to walk back through the history of the application in order to better understand (or remember) the application actions that were taken in the past and the triggers for those actions.

Abstract: A system for distributed information processing and interaction includes a plurality of output devices arranged to produce a respective output portion of a system output, a plurality of application processors and a state server in data communication with the plurality of application processors. Each respective output portion is defined by context information. Each application processor is configured to process one or more respective application programs and is responsive to the context information. Each application processor is coupled with an associated respective output device for controlling the output device in producing the respective output portion. The state server provides the context information to the plurality of application processors. The architecture is extended to a more general system in which output devices produce a variety of outputs including device actuations, as well as video displays, and receive a variety of inputs.

Abstract: The shared user interface surface system is a simple and lightweight collaboration tool that is accessible simultaneously by multiple users through multiple sources. The shared user interface surface system provides a way to share a user interface surface and corresponding shared surface object, and coordinates local manipulations of respective local representations of the shared user interface surface and corresponding shared surface object, and updates the respective local representations with a group representation. The system accommodates diverse collaboration requirements including mixed written and spoken languages, utilization of the accessibility layer for physically disabled and disparate computing resources.

Abstract: A system and method for determining positions of multiple targets on a planar surface is described. The targets subject to detection may include a touch from a body part (such as a finger), a pen, or other objects. The system and method may use light sensors, such as cameras, to generate information for the multiple simultaneous targets (such as finger, pens, etc.) that are proximate to or on the planar surface. The information from the cameras may be used to generate possible targets. The possible targets include both “real” targets (a target associated with an actual touch) and “ghost” targets (a target not associated with an actual touch). Using analysis, such as a history of previous targets, the list of potential targets may then be narrowed to the multiple targets by analyzing state information for targets from a previous cycle (such as the targets determined during a previous frame).
