Abstract: This disclosure relates to proximity sensing for wink detection. An illustrative method includes receiving data from a receiver portion of a proximity sensor. The receiver portion is disposed at a side section of a head-mountable device (HMD). When a wearer wears the HMD, the receiver portion is arranged to receive light reflected from an eye area of the wearer, the proximity sensor detects a movement of the eye area, and the data represents the movement. The method includes determining that the data corresponds to a wink gesture. The method also includes selecting a computing action to perform, based on the wink gesture. The method further includes performing the computing action.

Abstract: The present description discloses systems and methods for changing the state of a device. One embodiment may include a device configured to provide a device in a first state, receive a signal indicative of first angular data of the device, and compare the first angular data to a first threshold. The device may then execute instructions to initiate a timer when the first angular data is greater than the first threshold, receive a signal indicative of a second angular data of the device, and compare the second angular data to a second threshold. When the second angular data is less than the second threshold and the time passed is within a pre-determined time period, the device may execute instructions to transition the device to a second state.
