![]() ![]() We also analyse the necessity and impact of a systematic guided approach using extreme-user inspired design methods that inform designers of the experiences that would enhance the usability of their PSSs design. In this thesis, we empirically test the underpinnings of extreme-user experiences and simulated extreme-user experiences for design creativity. Therefore, there is an opportunity to advance creativity in mainstream PSSs design by systemic adoption of extreme-user experiences. While simulated experiences that emulate reduced physical and cognitive abilities are adopted to improve designers’ understanding of the needs among such extreme-users, they are seldom applied beyond the realms of assistive and inclusive design solutions, especially as a tool for design creativity. Works in the past have observed this potential (as the extreme-users) among the older adult users and users with reduced physical or cognitive abilities for the products, services, or systems (PSSs) that primarily target the mainstream general population users. This shift in perception is achieved by incorporating the perspectives of extreme-users who experience the latent unmet needs among the rest of the population and have the potential to inspire design professionals. Further, it demonstrates that relying on only the TAB key for supporting keyboard-only access is comparatively inefficient, and that Web developers should be actively encouraged to use all of the available functionality from Web 2.0 technologies to produce more flexible and efficient keyboard-only support.Įxtreme-user experiences have a unique potential to enhance designer creativity by altering one’s perception of their own designs. The case study also highlights that new Web 2.0 technologies support the implementation of accessibility solutions more typically only associated with non-Web applications. #Mouseless keyboard strategy fullThe most efficient method of input was a strategy of combined keyboard shortcuts offering access to the full functionality of the UI. #Mouseless keyboard strategy seriesThe paper further describes a series of experiments that were performed to demonstrate the usability of the new interface and also compares the efficiency and effectiveness of three different input strategies developed for the new UI. ![]() ![]() This paper examines the design of a user interface (UI) for use in an airport environment and explains how the lessons learned from research into designing for users with disabilities, in particular, have been applied in this new context. However, Universal Access is also about providing access to users in all situations and circumstances, including those that place extraordinary or unusual demands on the users who might otherwise not need assistance. Universal Access is commonly interpreted as focusing on designing for users with atypical requirements-specifically users with disabilities or older adults. ![]()
