Abstract [sv]

Tillhandahållande av information med hjälp av ett tillvägagångssätt som är både icke-visuellt och icke-auditivt såsom haptisk återkoppling kan vara en framkomlig väg när det gäller webbtillgänglighet för dövblinda. Haptiska navigationssystem har visat sig vara lätt att lära och modulerad navigeringsrelaterad Information som mönster av vibrationer ses som naturliga och icke störande. För att minimera den bandbredd som krävs, kan en varierande längd kodningsschema såsom morsekod övervägas. En prototyp av ett morsekodat vibrationsmodulsystem för webbsidesnavigering utvecklades med en vanlig spelkontroll som ett medel för utmatning. Resultaten visar att simulerade dövblinda försökspersoner som använder systemet kunde navigera en webbplats med framgång i tre fall av fyra. I vissa situationer presterade versionen av systemet med en högre grad av manuell interaktion bättre.

Abstract [en]

Providing information using a modality that is both non-visual and non-auditory 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.
