Exploration of multimodal alternative access for individuals with severe motor impairments: Proof of concept
Assist Technol. 2021 Mar 29. doi: 10.1080/10400435.2021.1910375. Online ahead of print.ABSTRACTMany individuals with complex communication needs and severe motor impairments are unable to control technologies through conventional means and require alternative access techniques to achieve accurate and efficient access. With current alternative access techniques, individuals with severe motor impairments are limited in that they can only use one access technique at a time. The purpose of this project was to test proof of concept of a new multimodal access technique which integrated eye gaze and single switch scanning selecti...

Evaluating person-centered factors associated with brain-computer interface access to a commercial augmentative and alternative communication paradigm
Assist Technol. 2021 Mar 5:1-10. doi: 10.1080/10400435.2021.1872737. Online ahead of print.ABSTRACTCurrent BCI-AAC systems largely utilize custom-made software and displays that may be unfamiliar to AAC stakeholders. Further, there is limited information available exploring the heterogenous profiles of individuals who may use BCI-AAC. Therefore, in this study, we aimed to evaluate how individuals with amyotrophic lateral sclerosis (ALS) learned to control a motor-based BCI switch in a row-column AAC scanning pattern, and person-centered factors associated with BCI-AAC performance. Four individuals with ALS completed 12 BCI...

Comprehensible Instructions from Assistive Robots for Older Adults with or without Cognitive Impairment.
CONCLUSIONS: The results imply that step-by-step instructions should be used for older people with lower levels of cognitive function, especially working memory, and repeated instructions may be required for lower attention. Types of instruction should be selected depending on cognitive characteristics. PMID: 33617400 [PubMed - as supplied by publisher] (Source: Assistive Technology)

Tablet Therapy as an Assistive Technology-Based Treatment for Anxiety in Pediatric Oncology.
Authors: Fraiser K, Burker E, Chan DV Abstract The painful interventions and invasive procedures associated with pediatric cancer treatment can result in anxiety. Anxiety can be reduced or better controlled through distraction and thought retraining. Although art therapy, non-electronic play therapy, music therapy, and traditional counseling are often used to alleviate stress and anxiety, new technology innovations are proving to be additional options to decrease stress and anxiety through distraction and attention shifting. Tablet-based interventions are emerging as an easily available and effective means of reduc...

A Computer Aided Drawing System Evaluation with Early and Late Blind Users.
Authors: Fernando S, Ohene-Djan J Abstract The present lack of suitable and efficient graphics creation techniques may place limitations on the career progression and life contentment of blind students. It is challenging for a BVI (Blind and Visually Impaired) person to draw diagrams or art, which are commonly taught in education or used in industry. The SETUP09 graphics creation system was developed to address a need for blind users to be able to create such content and consists of both navigation and computer aided drawing techniques, enabling graphics creation and manipulation through command language and intuit...

Staged treatment protocol for gait with hybrid assistive limb in the acute phase of patients with stroke.
In this study, we developed a novel staged HAL treatment protocol for patients with acute stroke. The Regain Program for Gait with HAL (RPG-HAL) was formulated in four steps, based on the severity of limb paralysis. Twenty-one patients with acute stroke received a combination treatment of RPG-HAL and conventional rehabilitation. The feasibility and safety of RPG-HAL were evaluated based on changes in physical function and activities of daily living (ADL). RPG-HAL yielded improvement in gait speed, cadence, step length, and functional ambulation category (FAC). The effect size was>0.8 in all measurements. FAC (1.90) and ...

Sunny Pointer: Designing a mouse pointer for people with peripheral vision loss.
Authors: Ambard M Abstract We introduce here a new mouse cursor designed to facilitate the use of the mouse by people with peripheral vision loss. The pointer consists of a collection of converging straight lines covering the whole screen and following the position of the mouse cursor. We measured its positive effects in a group of participants with peripheral vision loss of different kinds and found that it can reduce by a factor of seven the time required to complete a targeting task using the mouse. Using eye tracking, we show that this system makes it possible to initiate the movement towards the target without...

Visualization of user interactions with a pressure mapping mobile application for wheelchair users at risk for pressure injuries.
Authors: Goodwin BM, Olney CM, Ferguson JE, Hansen AH, Eddy B, Goldish G, Morrow MM, Vos-Draper TL Abstract Pressure injuries for individuals with spinal cord injuries (SCI) are correlated with mortality and are a leading cause for rehospitalizations. The Assisted Weight Shift (AW-Shift©) is a mobile pressure mapping application designed to provide users with a live map view and reminders to perform weight shifts. Novel visualization techniques were used to understand daily distributions of user interaction with AW-Shift©. The date and time of system interactions were recorded for six participants with SC...

Effects of domotics on cognitive, social and personal functioning in patients with Parkinson's disease: a pilot study.
This study aims to evaluate the effects of domotics on quality of life, and personal/social autonomy in PD patients. We enrolled 40 with PD undergoing neurorehabilitation, who were randomized into either the control (CG) or the experimental group (EG). Two different rehabilitative approaches were used: the CG was submitted to a traditional training, whilst the EG underwent HA training, in which the activities were carried out through the use of assistive technologies. In both the training, the exercises were performed in small samples of 3-5 patients. Results showed that both CG and EG had a significant improvement in glob...
