Digital talking books on a PC: a usability evaluation of the prototype DAISY playback software

his paper describes the design and evaluation of the first system to play digital talking books on a PC: the DAISY Playback Software. The features of the software for navigating through structured digital audio are described. A detailed usability evaluation of this prototype software was designed and conducted to assess its current usability, in which 13 blind/partially sighted participants completed a series of realistic tasks and answered detailed usability questions on the system. Recommendations for improvements are presented which might inform designers of similar systems, such as other digital talking book systems or WWW browsers.
