This paper describes the development of a platform-independent implementation of " 3D Sound Icons ". When a computer user has uncorrected visual impairments, the identification and selection of icons in a GUI may become significantly more difficult than for a normally sighted user. has indicated that approximately 8.7 million Americans who are 45 or older report a severe vision impairment that cannot be corrected by wearing eyeglasses or contact lenses. While the introduction of Graphic User Interfaces (GUIs) facilitated the interaction of normally sighted users with computers, these benefits are not equally extended to partially sighted individuals that suffer from limited visual acuity. Directions for future research are discussed and prioritized. ![]() Results demonstrated that spatialization of icon sounds provides additional remote navigational information to users, enabling new strategies for task completion. Experiments were conducted with simulated visual impairments on volunteer participants to evaluate if the addition of spatial auditory feedback makes the interface more accessible to users with impaired vision. A software prototype of the design was developed to evaluate the performance of users in the search of icons within the proposed interface. As the screen cursor traversed the screen, the user heard sounds of nearby icons, spatially, according to the relative position of each icon with respect to the screen cursor. In this augmented interface, unique sounds were mapped to visual icons on the screen. This paper investigates the addition of spatial auditory feedback as a tool to assist people with visual impairments in the use of computers, specifically in tasks involving iconic visual search. ![]()
