In this paper, we introduce the Activity Compass, a cognitive aid for early-stage Alzheimer’s patients. This device has a simple user interface based on the metaphor of a traditional navigation compass. By following an arrow and an icon, users who are disoriented or forgetful are assisted in reaching their destination. A server-based AI engine learns a model of routine user behavior, predicts their most likely destinations, and then directs the compass interface. By leveraging historic behavior, the interface needs no configuration; the compass automatically improves its suggestions by observing user response over time.(local copy)
