Example methods and systems activate and deactivate a voice interface based on gaze directions. A computing device can define a range of voice-activation gaze directions and, in some cases, define a range of social-cue gaze directions, where the range of social-cue gaze directions overlaps the range of voice-activation gaze directions. The computing device can determine a gaze direction. The computing device determines whether the gaze direction is within the range of voice-activation gaze directions. In response to determining that the gaze direction is within the range of social-cue directions, the computing device can activate a voice interface. In response to determining that the gaze direction is not within the range of social-cue directions, the computing device can deactivate the voice interface. |

1. A method, comprising:
displaying, on a see-through display of a head-mountable device, a graphical interface; defining, using the head-mountable device, a range of social gaze that provide a social cue indicating interaction with the head-mountable device, wherein the range of social gaze directions corresponds to voice-control activation; determining a gaze direction using an electromagnetic emitter/sensor (EES) configured to emit infrared radiation, detect the infrared radiation after reflection, and communicate reflection data about detected reflected infrared radiation to the head-mountable device; determining, using the head-mountable device, that the gaze direction is within the range of social gaze directions based on the reflection data, wherein determining that the gaze direction is within the range of social gaze directions based on the reflection data does not comprise mapping gaze direction to coordinates on the see-through display; and in response to the head-mountable device determining that the gaze direction is within the range of social gaze directions, (i) the head-mountable device activating a voice interface of the head-mountable device and (ii) displaying, on the graphical interface, a voice activation indicator at a location of the see-through display that is within the range of social gaze directions, wherein the voice activation indicator is configured to indicate that the voice interface is activated. |
