Abstract

Various innovations have been identified in assistive technology for the visually impaired. One of these innovations are systems that present feedback and information in a tactile format. These tactile systems have the potential to help the visually impaired, but there is little attention to how it can be combined with other assistive technology. In this research, we present a set of user requirements for tactile systems, focusing on the needs of the visually impaired. This is done by telephone, personal, and group interviews. As a result, we identify three themes related to the use of non-visual tactile assistive devices for blind persons: 1) context of use, 2) trust issues, and 3) user interaction. Our recommendations include focusing on a devices that solve very specific mobility problems, being transparent with users about system status such as battery life and accuracy, and limiting output to prevent overload
