“…Batavia and Hammer acknowledged that the study was preliminary in nature due to the small sample (n=12) not necessarily representative of the population and that the criteria were not tested for validity and reliability. Still, their study [19] is cited regularly in the literature and has been used as part of an AT framework [57]. The sample described in this paper is not considerably larger but as it was composed of professional users rather than end-users, the similarity between the results helps to validate both pieces of research.…”

“…The morphological matrix then structures the use of these issues as stimuli for concept and solution generation. This research builds on previous AT studies [4,19,57,58,67] and frameworks [5,54,55] and has attempted to develop the associated theories into a practicable design tool. Reinforcing the cross-disciplinary and knowledge sharing culture of the AT research community, the intention of this research is that the presented method will be adapted to generate and share contemporary crucial design issues about other AT domains.…”

Purpose. To develop and demonstrate a method to involve professional users of assistive technology (AT) in the development process of customisable products. Employing the ideas of user participation and mass customisation, this research addresses the need for reduced product costs and optimised product flexibility.Method. An adaptable six-question Delphi study was developed to establish consensus among AT professionals on design issues relating to a specified AT domain requiring innovation. The study is demonstrated for the special access technology (SAT) domain. A modified morphological matrix structures the application of the study results to the product design process. 2Results. 14 Professionals from the Republic of Ireland and the UK participated. Consensus was reached on prevalent parts of SAT that malfunction, primary reasons for SAT malfunction, characteristics of clients associated with SAT selection, client needs regarding SAT use and training, desirable traits of SAT, and clinicians" frustrations with SAT.Conclusion. The study revealed a range of problems related to SAT, highlighting the complexities of successful SAT adoption. The questions led to differentiated insights and enabled design solution conceptualisation from various perspectives. The approach was found to help facilitate efficient generation and application of professional users" knowledge during the design process of customisable AT. Implications for RehabilitationHigh product costs and device abandonment negatively affect many people who use assistive technology (AT). Poor device design is a root cause of these two problems.To address this issue, a method for the practical concept generation of customisable AT is proposed and demonstrated. The method aims to support the development of new, low-cost products which satisfy a broad range of consumers' needs.The literature requests suitable methods to facilitate the involvement of different types of AT users in the product design process. This paper presents a method to first establish consensus on important design issues for a specified AT domain, and subsequently to apply these issues to the product design process. This paper describes the method"s application for a customisable special access technology (SAT) device. Crucial design issues for SAT devices are presented to assist future SAT development work in research and industry. 3This research supports and provides validation for a number of past studies about desirable criteria for AT. These studies declared that further research was required to confirm their results.

“…Usability, within the realm of AT devices, determines how effectively and efficiently AT users with disabilities can function in different contexts and environments (Arthanat et al, 2007). In fact, senior citizens use assistive devices because the functional aspects of those products meet their current needs.…”

Abstract:In this paper, we present the SHARE-it approach to the integration of agent technology with other existing technologies to build specific intelligent and semi-autonomous assistive devices for older persons and people with disabilities (both cognitive and/or motor). In particular, we explored the benefits of the concept of situated intelligence to build mobility platforms and other artefacts that enhance the autonomy of the target user group in their daily life so that they can be self-dependent enough to autonomously live in their preferred environment.

Abstract-The purposes of this article are to describe usability testing and introduce designs and methods of usability testing research as it relates to upper-limb prosthetics. This article defines usability, describes usability research, discusses research approaches to and designs for usability testing, and highlights a variety of methodological considerations, including sampling, sample size requirements, and usability metrics. Usability testing is compared with other types of study designs used in prosthetic research.
