Abstract:
An interactive pointing device capable of switching capture ranges includes an image capturing element and a processing unit. The image capturing element is used for capturing an optical signal, and outputting an image signal. The processing unit is used for determining a switching signal, and responsible for processing and analyzing the image signal. Through the determination about the switching signal and the coordinate conversion of the image signal by an arithmetic unit, the interactive pointing device capable of switching capture ranges is enabled to be operable in hosts with different resolutions.
