Abstract: This disclosure involves proximity sensing of eye gestures using a machine-learned model. An illustrative method comprises receiving training data that includes proximity-sensor data. The data is generated by at least one proximity sensor of a head-mountable device (HMD). The data is indicative of light received by the proximity sensor(s). The light is received by the proximity sensor(s) after a reflection of the light from an eye area. The reflection occurs while an eye gesture is being performed at the eye area. The light is generated by at least one light source of the HMD. The method further comprises applying a machine-learning process to the training data to generate at least one classifier for the eye gesture. The method further comprises generating an eye-gesture model that includes the at least one classifier for the eye gesture. The model is applicable to subsequent proximity-sensor data for detection of the eye gesture.

Abstract: Systems and methods for processing spatial gestures are provided. In some aspects, depth data is received from one or more depth cameras. Positions of a plurality of body parts of a person in a field of view of the one or more depth cameras are determined based on the received depth data. A spatial gesture made by the person is determined based on the positions of the plurality of body parts. The spatial gesture is translated into an event. The event is provided, via a two-way socket, to a web client for executing a function in response to the event.

Abstract: Systems and techniques are disclosed for visually rendering a requested scene based on a virtual camera perspective request as well as a projection of two or more video streams. The video streams can be captured using two dimensional cameras or three dimensional depth cameras and may capture different perspectives. The projection may be an internal projection that maps out the scene in three dimensions based on the two or more video streams. An object internal or external to the scene may be identified and the scene may be visually rendered based on a property of the object. For example, a scene may be visually rendered based on where an mobile object is located within the scene.

Abstract: Example methods and devices are disclosed for generating life-logs with point-of-view images. An example method may involve: receiving image-related data based on electromagnetic radiation reflected from a human eye, generating an eye reflection image based on the image-related data, generating a point-of-view image by filtering the eye reflection image, and storing the point-of-view image. The electromagnetic radiation reflected from a human eye can be captured using one or more video or still cameras associated with a suitably-configured computing device, such as a wearable computing device.
