Abstract

A touch knob which can transmit user touches above to a touch-sensitive surface below includes a base, a rotating shaft, and a rotating cap. The rotating cap defines a receiving groove facing the base, and the rotating shaft extends into the receiving groove and is connected to the rotating cap. The rotating cap is configured to rotate to transmit user touches in a bounded circular area, at least one conductive touch head is located on the rotating cap and in the receiving groove, and moves as the rotating cap moves. The disclosure avoids the need to cut or form any opening in the cover of the touch-sensitive surface or panel for buttons to be installed. A device using the above touch knob is also provided.

Abstract

A structured light depth sensor for sensing a depth of an object, comprises: a projector for projecting structured lights with different codes to the object; a camera located on one side of the projector and configured for capturing the structured lights reflected by the object; a storage device for storing parameter information of the camera and distance information between the projector and the camera; and a processor electrically connected to the projector, the camera, and the storage device. The processor controls the projector to sequentially project the structured lights with different codes to the object, controls the camera to sequentially capture the structured lights reflected by the object, and calculates the depth of the object. A sensing method adapted for the structured light depth sensor is also provided.
