A method and apparatus for voice search. A voice search system for a voice-enabled device captures one or more images of a scene, detects a user in the one or more images, determines whether the position of the user satisfies an attention-based trigger condition for initiating a voice search operation, and selectively transmits a voice query to a network resource based at least in part on the determination. The voice query may include audio recorded from the scene and/or the one or more images captured of the scene. The voice search system may further determine whether the trigger condition is satisfied as a result of a false trigger and disable the voice-enabled device from transmitting the voice query to the network resource based at least in part on the trigger condition being satisfied as the result of a false trigger.

Vision-based presence-aware voice-enabled device

Disclosed is a device comprising: a light guide configured to receive incident light from one or more light sources; a cover layer with a sensing surface configured to receive an input object to be sensed; and a set of photodetectors. The light guide includes diffraction gratings configured to diffract the incident light as diffracted light, wherein the diffracted light exits the light guide and travels towards the sensing surface. The diffracted light is reflected from the sensing surface as reflected light. The reflected light is sensed by the set of photodetectors to form an image of the input object.

Systems and methods for optical imaging based on diffraction gratings

Disclosed are systems and methods for imaging an object. For example, an optical sensor for imaging an input object, comprises: a sensor substrate comprising detector pixels; a scattering layer; a cover layer including a sensing surface, wherein the scattering layer is disposed between the sensor substrate and the cover layer; and, a light source. The optical sensor is configured to: illuminate the light source causing light beams to emanate from the light source to produce an effect of a point light source at the scattering layer; and acquire image data, from one or more detector pixels, of an input object in contact with the sensing surface, wherein the image data corresponds to light from the light source that is reflected at the sensing surface of the cover layer.
