Abstract :
This paper presents the development of a computer peripheral device. This device implements the conventional mouse functions by sensing the user´s hand movement in the air. To achieve this purpose, the device implements a modified Kalman Filter to calculate the position of the mouse in the Y-axis through the fusion of a 3-axis accelerometer and a 2-axis gyroscope. For the X-axis an integration algorithm of the horizontal movement gyroscope signal was implemented. A USB HID stack in the microcontroller is used to perform the communication with the host computer.
