“…Models of assistive technology have sought to focus more on practical solutions to overcome barriers in access to communication technology for people with disabilities. The human activity assistive technology (HAAT) model (Cook & Polgar, 2013) describes an integrated system composed of the ‘consumer’ (the person with the disability), their activities, their context (social and physical environment) and the technology itself. The HAAT Model and it is extension the comprehensive assistive technology (CAT) model (Hersh & Johnson, 2008) focuses on a holistic and simultaneous evaluation of these four interrelated components, emphasising that a focus only on the technology or the person with the disability is likely to be ineffective in enhancing communication experiences or improving health and wellbeing outcomes.…”

Background Multimedia Advocacy is the use of digital technology for people with intellectual disabilities as means of developing identities, being heard, connecting to family and care networks and, advocating for change. Methods We explore principles and theories that underpin Multimedia Advocacy, mapping disciplinary approaches that have influenced the concept and praxis. Results We describe relevant theories from cultural and media studies, personal therapeutic practices, communication, universal design, and systemic adoption of technology. We discuss new ways of achieving person‐centred working with digital technology. We aim to develop a stronger theory/practice dialogue between these disciplines. Conclusions The theories described highlight the importance of embedding access and use of digital technology within everyday settings. Long‐term implementation plans and buy‐in from all organisational levels are required for Multimedia Advocacy tools to be embraced by health and social care systems so the voice of an individual is included and genuine person‐centred practice is achieved.

“…The social context refers to the interaction with others within the environment (23), including aspects such as attitudes and the social acceptability of the AT. Interestingly, the child's attitude towards the AT was viewed as most influential factor pertaining to the social context and was ranked 13 th overall.…”

“…The institutional context refers to "larger organisations in society" (23), such as the policies of the South African Department of Health or Department of Education. The financial provision of the institutional context (through tender policy in the public sector and medical aids in the private sector) was found to be the most influential factor in the institutional context, ranked in 17 th position overall.…”

“…This model indicates that AT selection takes place as a result of the interplay between environmental factors, personal factors (of the user of the AT as well as the RP), as well as specific decision making and ATD selection factors. This model was selected as it pertinently highlights the influence of the recommending RP on the AT selection process in contrast to other frequently-used models such as the Human Activity Assistive Technology (HAAT) model (Cook & Polgar, 2008) and the Matching Person and Technology Model (Scherer, 1998). The inclusion of the RP's influence on the process is compatible with the theory on professional reasoning, a process that underlies all clinical decision-making.…”

Disability and Rehabilitation: Assistive Technology

View full text Add to dashboard Cite

Purpose: Various factors influence the selection of assistive technology for young children within a context with limited resources, such as South Africa. Rehabilitation professionals are required to weigh up different factors as part of their professional reasoning process when making AT selections. Insight into the perceived influence of different factors may assist in understanding how professionals make decisions about AT in this context. Materials and methods: An online survey with questions designed using bestworst scaling was distributed to rehabilitation professionals throughout South Africa. Factors influencing assistive technology selection included in the best-worst survey were identified in previous phases of a larger project. A total of n = 451 rehabilitation professionals completed the survey by selecting the factors that were most and least influential on their assistive technology provision.Results: Results of the survey were obtained by calculating the number of times each factor was selected as most influential across the entire sample, and across all questions, enabling the researchers to sort the items in terms of the frequency of selection. Conclusions:Even though the rehabilitation professionals that participated in the study provide services in a context with limited resources, assessment and factors pertaining to the assistive technology itself were generally perceived to be of greater influence than environmental factors. It is recommended that these factors be reflected in frameworks and models of AT selection. IMPLICATIONS FOR REHABILITATIONThe family's ability to support the implementation of AT is an important resource that is perceived to influence the selection of AT by an RP. Insight into the mind-set of professionals that are used to selecting AT within settings with limited resources may provide RPs in well-resourced contexts with guidance on how to do more, with less. RPs should aim to determine child preference and attitude towards AT during the AT selection process. RPs should be aware of their own influence on AT selection. Existing AT Selection models should be adapted to clearly reflect the influence of the recommending professional.

“…In the last two decades various alternatives to the standard mouse have been developed to enable people with MIs to access graphical user interfaces (GUIs). These assistive technologies (ATs) seek to meet the special needs of this heterogeneous group of users who cannot grip or control standard mice [4] [5]. The most commonly used ATs to overcome this issue include specific alternative pointing devices (e.g., trackball or joystick), software applications such as mouse keys that enable the use of keyboards as an alternative to a mouse, or devices to support alternative manipulation (e.g., head wands or mouth sticks).…”

Longitudinal Study of Two Virtual Cursors for People With Motor Impairments: A Performance and Satisfaction Analysis on Web Navigation

et al. 2020

The lack of dexterity in the upper limbs of people with motor impairments may prevent the use of standard pointing devices, such as mice, to access graphical user interfaces. In these cases, pointing and clicking are usually performed by means of alternative devices such as joysticks, trackballs or standard keyboards. However, target acquisition can still be challenging for this group of people due to their physical condition. Based on previous works, we developed two virtual cursors: the novel cross cursor and the standard area cursor. They are devoted to assist two different groups of users with link selection within web pages: keyboard-only users, and joystick and trackball users, respectively. Both virtual cursors have been evaluated and compared with the original unassisted cursor in a longitudinal study. Eight people with motor impairments participated in an unsupervised experiment from their own personal computers at home. For a period of six weeks, each participant used both a virtual cursor and the original unassisted cursor to freely navigate the Web, and to perform predefined target acquisition tasks. Interaction data was automatically logged throughout the study along with subjective assessments concerning the usability of the virtual cursor being tested. Results show significant improvements for both virtual cursors in six of the seven cursor parameters studied, albeit with performance variations between some participants. The virtual cursors were extensively used for free web navigation and in their subjective assessments both were positively endorsed by participants who also put forward improvement suggestions for future developments. INDEX TERMS Alternative pointing devices, human performance, longitudinal study, people with motor impairments, user satisfaction, virtual cursors, web accessibility.
