Abstract

The invention discloses an interactive pointing device capable of switching an acquisition range and a method for switching the acquisition range. The interactive pointing device comprises an image acquisition element and a processing unit, wherein the image acquisition element is used for acquiring a light signal and outputting an image signal; and the processing unit is used for judging a switching signal and responsible for processing and analyzing the image signal. According to the image signal, the switching signal is judged and coordinates are converted by a computing unit, so that the interactive pointing device capable of switching the acquisition range can be operated in hosts with different resolutions.

Description

technical field [0001] The present invention relates to an interactive pointing device and a corresponding method, in particular to an interactive pointing device capable of switching a capture range and a method for switching the capture 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 th...
