In this paper a sensor fusion algorithm is developed and implemented for detecting orientation in three dimensions. Tri-axis MEMS inertial sensors and tri-axis magnetometer outputs are used as input to the fusion system. A Kalman filter is designed to compensate the inertial sensors errors by combining accelerometer and gyroscope data. A tilt compe...

Computing is now ubiquitous. Accessing the Internet is increasingly common from mobile devices through cellular networks. The Internet is now used for shopping, communicating, and for finding employment and housing. More information is readily available than at any time in human history; however, this information is often inaccessible to people wit...

This paper presents a rotation tracking system using a tri-axis MEMS accelerometer and a tri-axis magnetometer sensor that is placed on the human hand. This system recognizes the human wrist's rotation in the pronation-supination, extension-flexion and ulnar-radial movements. The proposed system also is able to measure the degrees of the rotations.

Blind and low-vision (BLV) individuals utilize systems called “Screen Readers” to navigate the World Wide Web. These systems retrieve the text information from the web pages accessed by a browser and convert this text to speech. However, typical screen readers process only one channel of audio and, therefore, convey the information from the web pag...
