Determining Interaction Geometry with Ultrasound Sensors

Just recently I finalized my Bachelor’s Thesis in Computer Science at the Technical University of Munich. The thesis is licensed under the Creative Commons CC-BY-SA 3.0 Unported license and is now available for download.

Abstract
In this thesis I present an ultrasound tracking system, which works infrastructure less and is based on mobile phones. I present the software and hardware, which is needed for this system to work. Then I describe the experiment I conducted to collect data of the system’s performance. Afterwards, this data gets evaluated in a way that it is compared to a high precision reference data set, which was already used to determine interaction geometry. Next, I discuss the system’s and experiment’s limitations and suggest some concrete improvements. Finally I conclude on the possibilities to determine interaction geometry, using the data my ultrasonic tracking system is able to collect and propose some future work in this area.
