Abstract [en]

Providing information using a modality that is both non-visual and nonauditory such as haptic feedback may be a viable approach regarding web accessibility for deaf-blind. Haptic navigation systems have been shown easy to learn and modulating navigation related information as patterns of vibrations is viewed as natural and non-intrusive. To minimise the bandwidth needed, a varying length encoding scheme such as Morse code may be considered. A prototype Morse code vibration modulated system for web page navigation was developed, using a standard game controller as a means of output. Results show that simulated deaf-blind test subjects using the system were able to navigate a web site successfully in three cases out of four. In some situations a version of the system with a higher degree of manual interaction performed better.
