Abstract

The invention discloses an interactive pointing device. The interactive pointing device comprises an image capturing component and a processing unit, wherein the image capturing component can be operated in a first capturing range and a second capturing range, and the image capturing component is used for capturing a light source and outputting a video signal. When a distance between the interactive pointing device and the light source is less than a reference value, the processing unit controls the image capturing component to detect the light source in the first capturing range, and converts the video signal into a first coordinate data; and when the distance is greater than the reference value, the processing unit controls the image capturing component to detect the light source in the second capturing range, and converts the video signal into a second coordinate data. Meanwhile, the invention also discloses a capturing range switching method.

Description

technical field [0001] The present invention relates to an interactive pointing device and a pointing method, in particular to an interactive pointing device capable of switching the capturing range and a method for switching the capturing range. Background technique [0002] In recent years, due to the rapid development of technology, interactive multimedia devices have become more and more popular. Interactive multimedia equipment allows users to interact with audio and video to achieve entertainment effects. [0003] Interactive multimedia equipment needs to be used with a control device. In addition to the control device can be controlled by buttons, the more advanced control device also has the technology of pointing and positioning and motion sensing. Pointing and positioning can control the cursor on the screen like a mouse, and motion sensing can detect movement and rotation in three-dimensional space. [0004] The technology of pointing and positioning requires t...
