Sensors and systems for the capture of scenes and events in space and time

摘要

Various embodiments comprise apparatuses and methods including a light sensor. The light sensor includes a first electrode, a second electrode, a third electrode, and a light-absorbing semiconductor in electrical communication with each of the first electrode, the second electrode, and the third electrode. A light-obscuring material to substantially attenuate an incidence of light onto a portion of the light-absorbing semiconductor is disposed between the second electrode and the third electrode. An electrical bias is to be applied between the second electrode, and the first and the third electrodes and a current flowing through the second electrode is related to the light incident on the light sensor. Additional methods and apparatuses are described.

主权项

1. A method of gesture recognition, the method comprising:
acquiring a stream, in time, of at least two images from each of at least one camera module; acquiring a stream, in time, of at least two signals from each of at least one light sensor; and conveying the at least two images and the at least two signals to a processor, the processor being configured to generate an estimate of a gesture's meaning, and timing, based on a combination of the at least two images and the at least two signals, the generation of the estimate of the gesture's meaning and timing including estimating both a direction of an object and a velocity of the object.
