Accessible Websites for People with Dementia: A Preliminary Investigation into Information Architecture

People with dementia have not traditionally been seen as a user group for website development. This paper describes the first attempts to discover some of navigation design needs when developing an information-based website for people with dementia. A card sorting methodology is described using existing information that is provided for people with dementia about their condition. Some participants with dementia found it difficult to group concepts together. This could have a profound affect on the design of good website

Voice Games: Investigation Into the Use of Non-speech Voice Input for Making Computer Games More Accessible

Part 2: Long and Short PapersInternational audienceWe conducted a quantitative experiment to determine the performance characteristics of non-speech vocalization for discrete input generation in comparison to existing speech and keyboard input methods. The results from the study validated our hypothesis that non-speech voice input can offer significantly faster discrete input compared to a speech-based input method by as much as 50%. Based on this and other promising results from the study, we built a prototype system called the Voice Game Controller that augments traditional speech-based input methods with non-speech voice input methods to make computer games originally designed for the keyboard and mouse playable using voice only. Our preliminary evaluation of the prototype indicates that the Voice Game Controller greatly expands the scope of computer games that can be played hands-free using just voice, to include games that were difficult or impractical to play using previous speech-based methods
