BLE空中鼠标系统的优化设计与实现
OPTIMIZATION DESIGN AND IMPLEMENTATION OF BLE AIR MOUSE SYSTEM
摘要
Abstract
In recent years,the application of air mouse is more extensive,but the existing air mouse has the following problems.(A) User inadvertently moves the mouse when the cursor is in the ‘ unknown’ position.(B) The use of lowpass filter to solve the key jitter method is easy to cause the cursor movement ‘ dead zone’.In order to solve the above problems,this paper introduced the design of BLE air system,and put forward the cursor positioning and fixing method to solve the ‘ unknown’ cursor and the "dead zone" problems respectively.At the same time,the combination of angle and acceleration was proposed to increase the diversity of cursor movement.Experimental results showed that the proposed scheme and the proposed method can effectively solve the above problems,so as to improve the overall performance of the air mouse.关键词
