Introduction: Development of a sensing device that can provide a sufficient perceptual substrate for persons with visual impairments to orient themselves and travel confidently has been a persistent rehabilitation technology goal, with the user interface posing a significant challenge. In the study presented here, we enlist the advice and ideas of…

The inability to navigate independently and interact with the wider world is one of the most significant handicaps that can be caused by blindness, second only to the inability to communicate through reading and writing. Many difficulties are encountered when visually impaired people (VIP) need to visit new and unknown places. Current speech or…

Computer-based communication has tremendous potential to support older adults. But if people are to use such systems autonomously, it is necessary to move beyond current interfaces and systems and develop devices that fit into the environment of the user. Using a Grounded Theory approach, three focus groups were held and, subsequently, 9 older…

Contextualised and ubiquitous learning are relatively new research areas that combine the latest developments in ubiquitous and context aware computing with educational approaches in order to provide structure to more situated and context aware learning. The majority of recent activities in contextualised and ubiquitous learning focus on mobile…

The concept of a community of practice (CoP) is prevalent in several venues for teachers' professional development, especially in online environments. However, there are few descriptive accounts that effectively represent a CoP in a manner that will be of use to other designers. In order to illuminate potential difficulties which may arise when…
