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.

Des applications de collaboration ou d~aide à la décision complexes réalisent des tâches de conception ou de planification complexes, bien souvent avec l~intervention de groupes importants de personnes et pendant des périodes de temps prolongées. L~effet combiné du temps et de la complexité masque souvent les actions passées, si bien qu~il est difficile de se remémorer les facteurs qui ont influencé des étapes antérieures d~une tâche de planification. Ceci vaut tout particulièrement pour une tâche faisant intervenir un grand nombre de personnes travaillant simultanément et à des moments différents. Lorsque des groupes de personnes collaborent simultanément, il est indispensable de pouvoir détecter et assurer le suivi de contacts ou mouvements simultanés multiples effectués par un utilisateur ou un outil d~utilisateur sur, ou à proximité d~une surface (par ex. sur une surface plane). Le système de détection de cibles multiples et de navigation entre des états d~applications offre un mécanisme indépendant d~une application permettant à des opérateurs d~exploiter une application en temps réel, et de retracer l~historique de l~application de façon à mieux comprendre (ou à se remémorer) des actions entreprises dans le passé et les motifs de ces actions.
