Abstract: A wearable computing device includes various biometric sensors for recording biometric measurements of a user wearing the wearable computing device. The wearable computing device is further configured to interpret the biometric measurements as commands to be performed. The wearable computing device also includes modules and logic that determine whether the biometric measurements were voluntary or involuntary movements by the user, which indicate whether the user intended such biometric measurements to be input to the wearable computing device. Where the biometric measurements indicate that the user's movements and/or gestures were voluntary, the wearable computing device is configured to further classify and analyze the biometric measurements. This classification and analysis yields the different types of actions and objects the user was engaged in or acting on at the time the biometric measurements were obtained.

Abstract: Visual gestures in a display device allow a user to select and activate features in a display of the display device. A sensor of the display device tracks an eye gaze of a user directed at a display of the display device. A visual gesture module identifies a predefined trigger zone in the display. A virtual object application displays a virtual object in the display based on the eye gaze of the user and the predefined trigger zone.
