Embodiment Construction
[0020] 1 Overview
[0021] Some implementations in the present disclosure relate to detecting eye blinks and the direction the eyes are facing before, during, or after the blink. This can be implemented in a head-mountable display, such as a glasses-style wearable computer, equipped with one or more proximity sensors. In some implementations, the HMD has a proximity sensor with a receiver portion disposed on a side of the HMD. Thus, in these implementations, when the wearer is wearing the HMD, the receiver portion is arranged at an oblique angle relative to the eye region and can detect light (eg, infrared light) reflected from the eye region. Additionally, the HMD may include a light source or set of light sources capable of providing light (eg, infrared light) to the eye region.
[0022] As the wearer's eyes change orientation or close, movement of the eyelids can cause changes in the intensity of light reflected from the eye area. By tracking the intensity of reflected l...

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.
Description
[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Application No. 13 / 550,791, filed July 17, 2012, which claims the benefit of U.S. Provisional Application No. 61 / 619,336, filed April 2, 2012, which are hereby incorporated by reference in their entirety incorporated. Background technique [0003] Computing devices, such as personal computers, laptops, tablet computers, cellular telephones, and countless types of networking-capable devices, are becoming increasingly ubiquitous in many aspects of modern life. Over time, the way these devices provide information to users is becoming smarter, more efficient, more intuitive and / or less obtrusive. [0004] Trends in the miniaturization of computing hardware, peripherals, and sensors, detectors, and image and audio processors, among other technologies, have helped open up a field sometimes referred to as "wearable computing." In particular, in the field of image and vision processing ...
