Henry Kautz, Craig Harman, & Joseph Modayil Richard Levinson & David Halper PEAT is a handheld cognitive aid designed for users with executive-function impairment due to Alzheimer’s disease, stroke, brain injury, and other disorders. Users are cued to start and stop activities using personalized voice recordings, digital photographs, and links to related name and note information. The system currently relies on users to self-report progress by pressing buttons on the handheld’s screen. This method of monitoring the user’s activity can be distracting and unreliable. We are enhancing PEAT with automated activity detection using RFID, GPS, and touch sensors. Data communicated wirelessly from environmental and wearable sensors is integrated on the handheld, enabling it to perform robustly indoors or outdoors, and with or without broadband connectivity. New functionality enabled by activity recognition includes the ability to include conditional compliance reminders. For example, if the system notes the user is leaving the house without taking his walker, it could reminder him to take it with him. |
