Air mouse: an everyday mouse for the ease of computing

There are several ways for human computer interaction in the modern era of electronics. In the present day, computers motion recognition is used very efficiently for playing games. The work done in this paper presents a simple and low-cost device for the movement of cursor on computer screen or to rotate the three-dimensional images. For the movement of cursor the data of accelerometer sensor (according to hand movement) is fed to the controller unit and after processing it is sent serially to the computer through RS 232 protocol. The developed device is used for all applications as accomplished with mouse. The proposed device senses the end user action with the help of accelerometer and push buttons. The air mouse is comfortable to wear, and does not considerably obstruct entering. It functions completely as serial mouse available in the market, and even has the feature of scrolling as the conventional mouse. This innovative approach improves the end user’s experience with day-to-day task and playing games in computer.
