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.
