基于便携式智能终端的空中鼠标技术研究
Research on technology of air mouse based on portable intelligent terminal
摘要
Abstract
In order to solve the inconvenience when human interact with large screen in some cases,using the portable intelligent terminal with MEMS sensors to solve the problem and an interactive system based on portable intelligent terminal is come up.The system overcomes the shortcoming of traditional mouse which depends on two-dimensional table.In order to overcome the drift of low accuracy gyroscope,the angle calculated from gyroscope and the angle calculated from accelerometer and magnetometer are used to perform the complementary filtering.The heuristic drift subtraction is used to deal with the error of the gyroscope,dynamically the compensation parameters of the heuristic drift subtraction are adjusted at the same time.The experimental results show that the improved algorithm can effectively overcome the drift of the gyroscope and improve the precision and stability of the air mouse system.关键词
