requirements of a Visually Impaired Person (VIP). Users of such a device may suffer
from conditions such as Macular Degeneration, Diabetes and HIV/AID’s related
disorders. Since these disorders affect a person’s vision, the device enlarges the desired
text to reduce the effects of loss of vision. Other functionality may include image
manipulation and colour modification.
A usability engineering framework is incorporated into the design as well as
accommodating user requirements in the design process. Usability principles are
implemented, hence meeting the aims of effectiveness, efficiency, learnability,
satisfaction and context of use. The device is examined via heuristic evaluation and
usability testing from specialists and end users, with comments, ratings and times
recorded. Research indicates that this device successfully implements usability
engineering techniques and provides a cost effective, highly functional device for the
VIP.
