MULTIPLE TARGET DETECTION AND APPLICATION STATE NAVIGATION SYSTEM

摘要

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 often obscures past actions, making it difficult to remember factors that influenced earlier stages of the planning task. This is especially true if the task involves many people working concurrently and at different times. When groups of people collaborate concurrently, detecting and tracking multiple simultaneous touches or movements by a user or user tool, on or near a surface (e.g., on a planar surface) is an essential capability. The multiple target detection and application state navigation system provides an application- independent mechanism that allows operators to operate an application in real-time, and 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.
