Application of novel rotation angular model for 3D mouse system based on MEMS accelerometers

Abstract

A new scheme is proposed to model 3D angular motion of a revolving regular object with miniature, low-cost micro electro mechanical systems (MEMS) accelerometers (instead of gyroscope), which is employed in 3D mouse system. To sense 3D angular motion, the static property of MEMS accelerometer, sensitive to gravity acceleration, is exploited. With the three outputs of configured accelerometers, the proposed model is implemented to get the rotary motion of the rigid object. In order to validate the effectiveness of the proposed model, an input device is developed with the configuration of the scheme. Experimental results show that a simulated 3D cube can accurately track the rotation of the input device. The result indicates the feasibility and effectiveness of the proposed model in the 3D mouse system.

Wearable inertial mouse for children with physical and cognitive impairments

“…Due to recent development in micro-machining technology, the cost of micromachined accelerometer is decreasing while the accuracy is being improved. Also, less fundamental physical constraints inhibit the precision of micro-machined accelerometer than that of gyroscope [42]. There are some head operated computer mouse that employs tilt sensors placed in a headset [11].…”

Motion sensing interface for the visualization of multidimensional data using inertial measurement

“…A 3D-mouse was discussed in [31] which uses two perpendicularly mounted planar (2-axis) accelerometers to detect the orientation (angular position) of the device much like the Wii-mote ( Our study of viable positioning systems for HCI applications led to choosing inertial systems for various reasons. One reason is that inertial systems can be made into a compact, stand-alone system.…”
