Ambiguous keyboards for AAC

Purpose – “Ambiguous keyboards” and “disambiguation processes” are becoming universally recognised through the popularisation of “predictive text messaging” on mobile phones. As this paper shows, although originating in the AT and AAC fields, these terms and techniques no longer appear to be widely understood or adopted by practitioners or users. The purpose of this paper is to introduce these techniques, discussing the research and theory around them, and to suggest them as AT and AAC strategies to be considered by practitioners and users. Design/methodology/approach – This is a conceptual paper that describes the use of ambiguous keyboards and disambiguation. The hypothesis of the paper is that ambiguous keyboards and disambiguation processes offer potential to increase the efficiency and effectiveness of AAC and should thus be considered further in research and practice. Findings – The two broad methods for removing the ambiguity from the output of an ambiguous keyboard are presented. A summary of the literature around the use of disambiguation processes provided and the use of disambiguation processes for AAC discussed. Originality/value – This paper suggests that ambiguity should be adopted as a characteristic of an AAC keyboard as should the method of removing ambiguity – namely either coding or a disambiguation process

Acting on behalf of the concept

This paper discusses how drama process and techniques are providing alternative approaches to product concept generation. An investigation that used drama techniques for concept generation sessions observed that there appears to be an implicit response among designers to investigate functionality before, or instead of form. However, it was proposed that through practice the approach of ‘concept-acting’ would provide support for the designer’s kinaesthetic needs for touch, feel and positional experience. It was also observed that whilst an increasing number of people in the US are actively embracing this type of approach, through a variety of techniques, UK designers appear somewhat more sceptical of the value of drama to their design processes
