TLDR
In this paper, an object detection system for capturing one or more sensor images of an object is provided that includes a touch system including a touch-sensitive screen and a display of a device.Abstract:
An object detection system for capturing one or more sensor images of an object is provided that includes a touch system including a touch-sensitive screen and a display of a device. The object detection system also includes a sensor system including a sensor array and a processing component. The sensor array is coupled to the touch-sensitive screen, and the processing component is configured to capture one or more images of an object when the object is detected by the touch-sensitive screen. At least a portion of the sensor array overlaps with at least a portion of the touch-sensitive screen.read more
