Characterization of low-cost accelerometers for use in a local positioning system

Abstract

The main goal of the project which this thesis is a part of, is to develop a system that can to track hand movements within a restricted area. The last few years has seen the development of several different relatively cheap systems with the ability to track position, velocity and heading of a device. These systems are usually based on ultrasound, electromagnetism or cameras with image recognition capabilities. The camera based systems can only function if there is a clear line of sight to all of the cameras. Ultrasonic systems also need line of sight between receiver and transmitter in order to achieve the wanted accuracy. The line-ofsight problem can to some extent be solved by integrating inertial sensor components into the system.
