Recently brain-computer interface (BCI) control was integrated into the commercial assistive technology product QualiWORLD (QualiLife Inc., Paradiso-Lugano, CH). Usability of the first prototype was evaluated in terms of effectiveness (accuracy), efficiency (information transfer rate and subjective workload/NASA Task Load Index) and user satisfaction (Quebec User Evaluation of Satisfaction with...

The purpose of this study was to conduct a cross-validation of the bidimensional structure of a satisfaction measure with assistive technology. Data were drawn from a follow-up study of 243 subjects who had been administered the Dutch version of the Quebec User Evaluation of Satisfaction with assistive Technology (QUEST). Ratings related to 12 satisfaction items were analysed. Factor analysis r...

The eyes play an important role both in perception and communication. Technical interfaces that make use of their versatility can bring significant improvements to those, who are unable to speak or to handle selection tasks elsewise, e.g. with their hands, feet, noses or tools handled with the mouth. Using the eyes to enter texts into a computer system, which is called gaze-typing, is the most ...

A requirements capture carried out with thirty blind and visually impaired participants has outlined many issues visually impaired people face when accessing the Web using current assistive technology. One key finding was that spatial information is not conveyed to users. An assistive multimodal interface has been developed that conveys spatial information to users via speech, audio and haptics...

Web accessibility and usability problems can make evaluation difficult for non-experts who may be unfamiliar with assistive technology. Developers often (i) lack easy access to the diversity of assistive technology employed by users, and (ii) are unaware of the different access patterns and browsing strategies that people familiar with a specific assistive technology tool might use. One way to ...

Young Mi Choi, PhD and Stephen H. Sprigle, PhD, PT Center for Assistive Technology and Environmental Access, College of Architecture, Georgia Institute of Technology, Atlanta, Georgia, USA ABSTRACT User input is an important component to help guide designers in producing a more usable product. Evaluation of prototypes is one method of obtaining this input, but methods for evaluating assistive t...

Assistive technology has become one of the most powerful tools in assisting people with disabilities fight for social equality both in Puerto Rico as well as in other cities worldwide. In spite of this, the availability of assistive technology equipment does not constitute reason enough for people with disabilities to have all the technology resources for making them independent and productive ...

This paper looks at different ways of personalising web page presentation to alleviate functional impairments in older people. The paper considers how impairments may be addressed by web design and through various personalisation instruments: accessibility features of standard browsers, proxy servers, assistive technology, application adaptors, and special purpose browsers. A pilot study of fiv...

Based on resource-oriented conceptions of successful lifespan development, we propose three principles for evaluating assistive technology: (a) net resource release; (b) person specificity, and (c) proximal versus distal frames of evaluation. We discuss how these general principles can aid the design and evaluation of assistive technology in adulthood and old age, and propose two technological ...
