Publication number: 20140016113Abstract: The subject disclosure is directed towards a distance sensor that outputs one or more (e.g., infrared) light patterns from a transmitting element. Signals from any reflective entity (e.g., a surface or object) within the sensor's range are captured by a receiving element. The captured image is digitized into digital data representing each light pattern, and the digital data is processed (e.g., including using triangulation) to determine distance data of the distance sensor relative to the reflective surface.Type: ApplicationFiled: December 12, 2012Publication date: January 16, 2014Applicant: Microsoft CorporationInventors: James A.
