Low Cost AR Design Challenges

Innsbruck University, Austria publishes BSc thesis "Developing a Low-Cost Augmented Reality System" by Carsten Fischer, talking about camera design issues, among other stuff:

"The goal of this document is to give the reader a better understanding of the underlying theory of augmented reality systems and which adaptations can decrease the cost of such systems, while maintaining a good experience. The requirements on the including hardware parts will be explained, before summarizing the manufacturing process and highlighting features of the including software. Finally the system will be evaluated, by conducting a user study on depth perception."
