Head-mounted device with feedback

Abstract:

A head-mounted device can be operated to detect and respond to a user's behavior. The head-mounted device can be regularly and frequently worn while the user performs regular daily tasks, allowing the head-mounted device to collect a large volume of data across a long duration of time so that the cognitive status of the user can be evaluated with greater confidence than may be achieved with an evaluation of short duration and/or frequency. Evaluations performed by the head-mounted device can facilitate the determinations of which disorder is present, a severity of the disorder, trends, and/or forecasts. The head-mounted device can provide feedback that can guide and direct a user to correct actions despite a tendency to do otherwise due to cognitive decline.
