Abstract: A motion controlled handheld device includes a display having a viewable surface and operable to generate an image and a gesture database maintaining a plurality of gestures. Each gesture is defined by a motion of the device with respect to a first position of the device. The gestures comprise symbol gestures each corresponding to a character from a preexisting character set. The device includes an application database maintaining at least one application and a gesture mapping database comprising a gesture input map for the application. The gesture input map comprises mappings of the symbol gestures to corresponding inputs for the application. The device includes a motion detection module operable to detect motion of the handheld device within three dimensions and to identify components of the motion in relation to the viewable surface.

Abstract: In particular embodiments, a method includes accessing data streams from a first group of physiological sensors monitoring a person, a second group of deconfounding sensors monitoring the person, and a third group of sensors monitoring a stressor, analyzing data sets collected from the person when the person is exposed and not exposed to the stressor, and determining a current stress factor for the stressor with respect to the person based on the analysis.

Abstract: In particular embodiments, a method includes accessing one or more physiological data streams, analyzing each physiological data stream in reference to a set of control parameters, and, if a data stream deviates from its control parameters, then transmitting a query to a mood sensor or a behavioral sensor.
