The Planning and Execution Assistant Trainer (PEAT) is a cognitive aid designed for use by individuals with brain injury or cognitive or memory disabilities. This handheld computer system provides customized cueing and scheduling and offers flexibility in handling schedule changes. The system's Activity Model describes the user's activites. Different types of user activities that can be defined in PEAT include:
Standard tasks (tasks with fixed start times);
To Do tasks (scheduled for specific days, but have no specific start time); and Floating Tasks (can be scheduled anytime in a specified time window). The system also offers Activity Scripts, hierarchical task sequences that help break high-level, multi-step activities into smaller steps. The User Interface is highly flexible and can be configured many different ways to meet individual needs and capabilities. Options include the ability to remove any button that might confuse a user, and the ability to block user access to view or modify data. The user interface enables cue types to be chosen from a wide range of multimedia cueing options, including customized voice or audio recordings and personalized digital pictures. It also enables users to be locked into the Cue Card section only so they only see reminders for one event at a time, while others may have the ability to view the calendar and note info, but not modify it, and yet other users may have full access to all features. It is also possible for users to override cues by starting and stopping them early, and by delaying, skipping, rescheduling, and cancelling them, while others may have the "cue override" features turned off. After PEAT cues the user, it then monitors their response to detect problems and adust when necessary.
