Innovation for inclusive design: an approach to exploring the iDTV design space

ABSTRACT

This paper describes an approach to the elicitation of accessibility requirements both to improve the design of existing technologies and develop new DTV utilities. The approach builds on previous work in which stalking-horse prototypes were used to explore possible design enhancements to interactive TV facilities. We describe a model of interaction with iDTV facilities that can be used to isolate areas of a design where those with impairments are likely to have difficulties and need alternative of modified design features. This incorporates a model of recovery strategies deployed during interactive sequences. The later section describes a creative technique for follow-up analyses of prototype evaluations. The technique is aimed at participatory exercises in which subjects are exposed to prototype designs or scenarios and encouraged to contribute ideas for re-designs and novel applications.
