Distributed cognitive aid with scheduling and interactive task guidance.

A cognitive assistive technology system has been designed for use by people with memory and organizational impairments. This system will provide a distributed architec- ture for both scheduling assistance and task guidance, as well as intelligent, automatic replanning on the levels of both the schedule and individual tasks. A prototype of this architecture has been developed that focuses on interactive task guidance capabilities. Scheduling software has been developed but not fully integrated with the task guidance features. The system has been preliminarily tested through simulated trials, moni- tored use of the prototype in a clinical setting, and usability trials of the task-design interface with rehabilitation profes- sionals. Participants were able to respond appropriately to cues provided by the system and complete prescribed tasks.
