Assistive Technology (AT); broadly defined as specialist equipment designed to promote computer access for people with disabilities, is increasingly becoming popular among people with vision impairment as computer use becomes commonplace in society. In developing and emerging economies, however, the adoption of ATs continues to lag behind the developed countries. This study explored barriers to adoption of assistive technologies among visually impaired people in five southern states in Nigeria. A mixed method approach that employed qualitative interviews with 20 participants and structured questionnaires among 423 participants aged between 20 and 92 was employed...

Currently, virtual applications for physical exercises are highly appreciated as rehabilitation instruments. This paper presents a middleware called "MoKey" (Motion Keyboard), which converts standard off-the-shelf software into exergames (exercise games). A configurable set of gestures, captured by a motion capture camera, is translated into the key strokes required by the chosen software. The present study assessed the tool regarding usability and viability on a heterogeneous group of 11 participants, aged 5-51, with moderate to severe disabilities, and mostly bound to a wheelchair...

The impact of assistive technology (AT) services for college students with less-apparent disabilities is under-reported. Using the Canadian Occupational Performance Measure (COPM), we assessed student Performance and Satisfaction ratings of common academic tasks at the start and end of a semester during which 105 student-clients with less-apparent disabilities received AT services. We examined if COPM initial and change scores related to personal characteristics of gender, class-level (e.g., Sophomore), and STEM education; if personal characteristics predicted a student's follow-through with an AT service referral (n = 231); and if personal characteristics and initial COPM scores predicted dropout from AT services (n = 187)...

As the number of older adults living with chronic conditions continues to rise, they will require assistance with activities of daily living (ADL) and healthcare tasks to continue living independently in their homes. One proposed solution to assist with the care needs of an aging population and a shrinking healthcare workforce is robotic technology. Using a cross-sectional survey design, we purposively sampled adults (≥18 years old) to assess generational acceptance and perceived usefulness of robots to assist with ADLs, healthcare tasks, and evaluate acceptance of robotic healthcare assistance across different settings...

Joan Pahisa-Solé, Jordi Herrera-Joancomartí
In this paper, we describe a compansion system that transforms the telegraphic language that comes from the use of pictogram-based Augmentative and Alternative Communication (AAC) into natural language. The system was tested with 4 participants with severe cerebral palsy and ranging degrees of linguistic competence and intellectual disabilities. Participants had used pictogram-based AAC at least for the past 30 years each and presented a stable linguistic profile. During tests, which consisted in a total of 40 sessions, participants were able to learn new linguistic skills, such as the use of basic verb tenses, while using the compansion system, which proved a source of motivation...

Eitan Raveh, Isabella Schwartz, Naama Karniel, Sigal Portnoy
Regaining the ability to independently ambulate following a physical disability can increase functional ability and participation of patients in daily life. Gait trainers are assistive devices that enable body support and provide safety during gait. However, most conventional gait trainers are pre-configured to a constant position, therefore not suitable for practicing sit-to-stand function, and require assistance from a caregiver in order to mount the device from a sitting position. We therefore evaluated the effectiveness of a dynamically-adjusting gait trainer, designed to provide independence and safety during gait and various activities, in both lab setting and at home in four subjects (one female, three males, ages 32-79 years) with limited ambulation...

Persons with an intellectual disability (ID) are at risk of developing separation anxiety (SA) and, if left untreated, this can be a risk factor for the development of psychopathology. The effects of an intervention, namely technology assisted therapy for SA (TTSA), were examined on the SA, challenging behavior, psychosocial functioning, and quality of life (QOL) experienced by moderate to mild intellectually and visually disabled adults. This study aimed to determine whether TTSA reduces SA and challenging behavior in persons with ID and visual impairment, and if this results in increased psychosocial functioning and QOL...

Åsa Larsson Ranada, Helene Lidström
The service delivery process (SDP) of assistive technology devices (ATDs) is attracting interest, as the provision of ATDs is critical for the independence and participation in society of individuals with disabilities. The purpose of the current study was to investigate what impact the SDP has on satisfaction with ATDs in individuals with disabilities in relation to everyday activities. A systematic literature review was conducted, which resulted in 53 articles included. The results showed that there are factors in almost all the different steps of the SDP that affect the satisfaction with of the devices, which can lead to underutilization and abandonment of ATDs...

This study investigated whether a self-designed assistive listening device (ALD) that incorporates an adaptive dynamic range optimization (ADRO) amplification strategy can surpass a commercially available monaurally worn linear ALD, SM100. Both subjective and objective measurements were implemented. Mandarin Hearing-In-Noise Test (MHINT) scores were the objective measurement, whereas participant satisfaction was the subjective measurement. The comparison was performed in a mixed design (i.e., subjects' hearing status being mild or moderate, quiet versus noisy, and linear versus ADRO scheme)...

A rear mounted, powered, drive wheel has been developed to assist with mobility for manual wheelchairs. The version tested operates in two modes (indoor and outdoor). To start in the indoor mode users must initiate propulsion with sufficient force to trigger the motor. To stop users must apply a braking force through the handrims. . The objectives of this study were to compare (1) the minimum force required to start a wheelchair with and without the drive, and (2) the distances and forces needed to stop a wheelchair at different treadmill speeds with and without the device...
