This summer I worked on a research project under the supervision of Professor E. Milios. The project was concerned with the conversion of distance readings into audible sound to potentially aid in obstacle detection and mobility for the visually impaired. For further information visit the following:  (The imgae appearing to the left was reprinted from the web page of Peter Mejeir developper of the vOICe)

BACKGROUND (including a description of several Electronic Travel Aids):

• Some past and presesnt devices to aid blind people with mobility.
• Past and present research conducted.
• Mobility Aids (much more than obstacle detectors!).
• Some related research topics.

• Introduction to Serial Communications

• Summer '97 Report (Summary)
• Summer '97 Report (Complete)

• Summer '98 Report (Summary - Submitted to ICAD 99 conference)
• Summer '98 Report (Complete)
