Conclusions:

I have learned much about serial communications, audio generation using the SUN workstation, the perception of sound by humans and Electronic Travel Aids. In addition, the information gathered and the software written during this four month period will serve as a framework for any continuation on this project. Although extensive testing was not carried out due to hardware limitations and lack of time, I believe the project was successful.

Acknowledgements:

I would like to thank Professor Milios and Greg Reid for their help with many of the problems I encountered while working on this project. I would also like to thank Antonin Pribetic,Barrister & Solicitor and Nancy Kapralos for taking time off their busy schedule to proof-read my final report.
