Abstract
A stroke detection device includes a cell phone having a sensor adapted to sense a characteristic of the user of the cell phone. An app executed by the cell phone passively monitors the characteristic to determine if the user has experienced a stroke. The app requests that the user take one or more tests using the cell phone if the presence of a stroke is possible. The tests include the user speaking a specific phrase into the cell phone that is compared to a previously recorded sound sample of the user; the user taking a picture of himself or herself with the cell phone that the app compares to a previous picture of the user; and the user attempting to hold his or her arm out straight while holding the cell phone wherein accelerometers in the phone measure the steadiness of his or her arm.
