Wireless headset communications for vision impaired persons in multi-User environments

摘要

Wireless headsets are a great asset to Vision Impaired Persons (VIP's) as they prove to be much easier to use and reliable than wired equivalents. Radio based wireless headsets are the most common and have many favorable characteristics, however for environments where there may be numerous users with wireless headsets, radio channels easily become congested compromising audio quality and reliable operation. The research undertaken in this project attempts to sidestep the radio channel congestion problem and also produce a wireless headset tailored to the requirements of VIP's.
