摘要:
A method for sensing, in an electronic device, the presence and inferring therefrom an intent of an object includes sensing a baseline ambient spatial average temperature for a sensed field of view, monitoring the sensed field of view for a variation in the ambient spatial average temperature of the field of view relative to the baseline, characterizing any detected variation, determining whether the detected variation is a recognized variation, and causing the electronic device to take at least one predetermined action responsive to a recognized variation.
