Disability and Rehabilitation-Assistive Technology最新文献

Background: Existing image description methods when used as Assistive Technologies often fall short in meeting the needs of blind or low vision (BLV) individuals. They tend to either compress all visual elements into brief captions, create disjointed sentences for each image region, or provide extensive descriptions.

Purpose: To address these limitations, we introduce VIIDA, a procedure aimed at the Visually Impaired which implements an Image Description Approach, focusing on webinar scenes. We also propose InViDe, an Inclusive Visual Description metric, a novel approach for evaluating image descriptions targeting BLV people.

Methods: We reviewed existing methods and developed VIIDA by integrating a multimodal Visual Question Answering model with Natural Language Processing (NLP) filters. A scene graph-based algorithm was then applied to structure final paragraphs. By employing NLP tools, InViDe conducts a multicriteria analysis based on accessibility standards and guidelines.

Results: Experiments statistically demonstrate that VIIDA generates descriptions closely aligned with image content as well as human-written linguistic features, and that suit BLV needs. InViDe offers valuable insights into the behaviour of the compared methods - among them, state-of-the-art methods based on Large Language Models - across diverse criteria.

Conclusion: VIIDA and InViDe emerge as efficient Assistive Technologies, combining Artificial Intelligence models and computational/mathematical techniques to generate and evaluate image descriptions for the visually impaired with low computational costs. This work is anticipated to inspire further research and application development in the domain of Assistive Technologies.

Welfare technology (WT), defined as digital technology enabling individuals to live securely, actively and independently at home, is often viewed as a solution to care resource shortages. This solution discourse has increasingly been problematised, and ethical issues specifically connected to WT have emerged, e.g., regarding quality of care. The existing array of WT is developed with limited user involvement; primary user perspectives are thus inadequately voiced in research. This study aimed to disentangle how older adults and their homecare staff experience and influence WT use in homecare situations. The qualitative approach encompassed individual semi-structured interviews with homecare staff (n = 26) and older adults (n = 26) receiving homecare as well as utilising WT. Interviews were conducted in five Swedish municipalities, transcribed verbatim and analysed using thematic analysis. Three main themes were developed: (1) Lack of agency in WT obtainment, in which a lack of influence in the receiving of WT is illustrated. (2) Contradictory user perspectives regarding WT and agency, in which staffs' perceptions of specific WT are contrasted to older adults', highlighting how WT perceived positively by staff often detract from older adults' agency. (3) Agency and WT use inextricably linked with time, in which it is illustrated how influence over time is intricately connected to experienced agency in WT use. Our findings demonstrate a problematic lack of agency in WT use. Further improvements to current WT, aided by stronger user involvement, as well as certain municipal routines, are necessary if user agency is to be strengthened in relation to WT use.

Purpose: Assistive technology (AT) can significantly enhance the daily lives of people with disabilities if matched appropriately to the individual and their context. Gaps remain in the AT sector in terms of provision and uptake. Consequently, this study examined current experiences and needs regarding AT provision throughout Queensland from AT users' perspectives.

Materials and Methods: Convenience and snowball sampling recruited participants for this exploratory sequential mixed methods study. Descriptive statistics summarized online survey responses (n = 41) and thematic analysis was completed to analyze qualitative interview data (n = 20).

Results: Survey results revealed that whilst all participants used AT, 68% had unmet AT needs. Satisfaction with AT reduced as AT users proceeded through the AT pathway. Three themes were identified from the interviews: (1) Expertise and collaboration are required: "One size doesn't fit all, and one solution doesn't fit all problems," (2) Process rejections and delays: "You're really left high and dry," and (3) Many factors impact the AT experience.

Conclusions: Findings indicate that although AT users had clear ideas of their AT needs and goals, they were often unable to access desired AT due to systemic barriers. Any attempts to overcome barriers for AT provision will need to be multi-level and there is a clear need to enhance current AT trial approaches.

Guidelines for implementation of eye-gaze control technology by people with cerebral palsy were published in 2021. The purpose of this study was to identify barriers and facilitators clinicians perceive exist relating to use of these guidelines for eye-gaze control technology, and to explore potential resources that may be developed to support their implementation. A two-phased mixed methods explanatory sequential design was adopted. In phase 1, an online survey containing quantitative and open-ended questions was completed by 97 health professionals and in phase 2 two online focus groups of five clinicians were conducted. The guidelines for eye-gaze control technology were considered helpful for clinicians new to eye-gaze control technology, useful to provide insight into processes for implementing eye-gaze control technology, were flexible, supported clinical reasoning and professional credibility, and were easy to use. However, time to read the guidelines for eye-gaze control technology, and insufficient funding for time to implement the technology were prominent barriers identified in this study. Through the qualitative findings four themes emerged: (1) Complexity of learning to use and implement the guidelines for eye-gaze control technology; (2) Time and resources in short supply; (3) Takes a dedicated team working together; and (4) guidelines for eye-gaze control technology informing practice. Participants in both study phases identified: case studies and video examples; education and training; and practice in implementing eye-gaze control technology, as facilitators to aligning their practice with the guidelines for eye-gaze control technology recommendations and to optimise outcomes.

Dyslexia is defined as a specific learning disorder that impairs a person's ability to read fluently and accurately. A growing number of assistive technologies have been used to support individuals with dyslexia. Eye-tracking technology is one such technology, and it is gaining increasing attention from the research community due to its potential to be a valuable support tool for identifying underlying neural differences in language processing among this population. While the technology has seen significant advancements in recent years, researchers, particularly in psychology and special education, might face difficulties utilizing eye-tracking technology in their dyslexia research. The present study aims to provide a comprehensive overview of how eye tracking is employed in this field. By analysing 71 papers, we investigated the range of dyslexia-related aspects that were addressed by eye-tracking technology, how the technology was used, and the connections between eye-tracking measurements and reading in studies including individuals with dyslexia. This review article reveals that researchers have long recognized the potential of eye tracking in dyslexia research, as evidenced by the consistent focus on this technology in relevant studies throughout the years. Our paper also indicates the value of eye-tracking technology in exploring a wide range of dyslexia-related aspects. These include reading behaviours and information searching, the impact of materials on reading performance, detection, intervention, and the evaluation of intervention outcomes. Furthermore, by exploring both the achievements and shortcomings, the paper offers a valuable roadmap for future research specifically focused on supporting individuals with dyslexia.

There is emerging evidence that LEGO® therapy is an effective way of supporting younger autistic children develop their communication and social skills. LEGO® robotics therapy - which uses the principles of LEGO® therapy applied to LEGO® robotics - may be an age-appropriate intervention to reduce anxiety and increase social skills in autistic adolescents. The aims of this study, involving 24 autistic students aged 13-16 years, were to examine (a) the effect of an 8-week LEGO® robotics therapy on students' anxiety, social skills, academic motivation, and engagement, and (b) the views and perceptions of all stakeholders (students, parents, school staff and facilitators) regarding the program. An adapted explanatory sequential basic mixed-methods design was used. Groups of three students supported by two facilitators participated in the LEGO® robotics therapy for eight sessions at school. Quantitative data was collected before and after therapy using the Anxiety Scale for children-Autism Spectrum Disorder, Social Skills Improvement System and the Motivation and Engagement scale. Qualitative data was collected using open-ended online questionnaires, interviews, and focus groups from all stakeholders. No statistically significant within group differences were found in relation to students' anxiety, social skills, motivation and engagement before and after the program. Qualitative findings indicated predominantly positive student experiences and outcomes such as better school attendance, increased confidence, and social skills. The findings suggest that LEGO® robotics therapy may be associated with a range of nuanced positive experiences and outcomes for individuals and groups of students, suggesting potential value in further efforts to refine the program.

Introduction: People living with chronic obstructive pulmonary disease (COPD) encounter challenges in everyday life activities due to symptoms like breathlessness and fatigue. Compensatory strategies, such as using everyday technology (mechanical, electronic and digital equipment and functions encountered daily) and assistive technology (products, instruments, or equipment adapted or designed to improve functioning of people with disabilities), are crucial for supporting everyday life activities; thus, it is essential to explore therapeutic potentials of these technologies. The present review aims to synthesise research literature concerning the use of everyday technology and assistive technology to support everyday activities among persons living with COPD.

Methods: A narrative review was conducted with a systematic search in five bibliographic databases. Three sets of search terms were used: (i) everyday technology, assistive technology, and related terms, (ii) everyday life activities and related terms, and (iii) chronic obstructive pulmonary disease and related terms.

Results: Screening resulted in 26 included articles.Following the American Occupational Therapy Association framework, the identified articles show six categories of everyday life activities supported by everyday technologies and assistive technologies: health management, social participation, activities of daily living, instrumental activities of daily living, leisure, and rest and sleep.

Conclusion: Most articles focus on everyday technology for health management; however, everyday technology may hold unexpected potential to support a broader array of everyday life activities. Little is known about assistive technology to support everyday life activities for people with COPD, though it is described as crucial for independence and energy conservation.

Purpose: In less-resourced settings, 80% of people with spinal cord injuries die from pressure ulcer complications within two years. Appropriately constructed wheelchair cushions are effective in reducing incidence and severity of pressure ulcers. The Tuball is an inexpensive wheelchair cushion designed for users in less-resourced settings, which can be reproduced by local clinicians using locally sourced materials. This paper aimed to assess whether different individuals with limited knowledge of cushion construction could reliably construct the Tuball cushion.

Materials and Methods: A convenience sample of eleven occupational therapy students were randomly assigned to one of two groups. Six participants constructed a Tuball and completed a subjective workload assessment. Five different participants sat on each cushion while pressure distributions were mapped. Intraclass correlation coefficients (ICC) with 95% confidence intervals were calculated for reliability of construction of each cushion using data from a range of pressure indices: dispersion index (primary outcome), peak pressure index, contact area, and seat pressure index (secondary outcomes) across all six cushions.

Results and Conclusions: The ICC across all cushions was 0.745 (95% CI 0.103-0.970) for dispersion index. ICCs across cushions for secondary outcomes ranged from 0.879 to 0.951. Good-moderate reliability was found for the reliability in cushion construction as measured by the dispersion index. Excellent reliability in cushion construction was found as measured by peak pressure index, contact area, and seat pressure index. Data indicates individuals can reliably construct the Tuball given equivalent materials and instructions.

Purpose: The study aims to examine the association between disability status and willingness to share wearable devices and mobile apps data for public health research using the 2017 Behavioral risk Factor Surveillance System (BRFSS) through secondary data analysis.

Materials and Methods: Current wearable device and mobile apps users at the time of the 2017 BRFSS survey administration from eight states were included in the analysis. Descriptive, chi-square analysis, and multivariable logistic regressions were performed to examine the associations. Subsample analyses were also conducted for individuals with disabilities and different types of disability, including visual impairments, hearing impairments, cognitive disability, independent living disability, self-care disability, and mobility disability on their willingness to share wearable device and mobile app data.

Results: Among the 1575 wearable device and mobile app users, 17.8% (95% CI [14.6, 22.0]) were participants with disabilities. Less than half of the participants (43.8%, 95% CI [38.0, 50.0]) were willing to share their data for public health research with no significant differences between those with and without disabilities or among specific disability types.

Conclusion: The findings underscore a general reluctance to share information for public health research. To address this reluctance, it is crucial to enhance public awareness of the potential benefits and educate users on how sharing data could contribute to understanding health behaviors and identifying public health needs.

Purpose: The main aim of this study was to compare sitting pressure (peak pressure index (PPI) and peak pressure gradient (PPG)) between a daily wheelchair and fixed-frame handcycle, thereby assessing the effect of handcycle backrest angle, movement intensity and cushion type.

Materials and methods: Twenty able-bodied participants performed static and dynamic (two intensities) tests in a wheelchair and handcycle. A honeycomb wheelchair cushion and standard foam handcycle cushion were used. Handcycle backrest angles were 45° and 60°. The PPI and PPG at the sacro-coccygeal (SC) and ischial tuberosity (IT) regions were determined with a pressure mat.

Results: PPI at the IT-region was higher in the 60° handcycle condition than in the wheelchair (p = 0.04), while PPG at the IT-region did not differ significantly between the wheelchair and handcycle conditions (p > 0.05). PPI and PPG were higher at the 45° handcycle SC-region compared to the wheelchair IT-region (p < 0.03). PPI and PPG at the IT-region were higher with the 60° than with the 45° backrest angle (p < 0.01), while at the SC-region PPI was higher with the 45° backrest angle (p = 0.047). No clear influence of movement intensity was found. PPI and PPG at the IT-region and PPI of the SC-region in the handcycle were significantly lower with the wheelchair cushion than with the handcycle cushion (p < 0.01).

Conclusion: Overall, sitting pressure was higher in the handcycle compared to the daily wheelchair. For handcyclists using an upright position, it is recommended to use a cushion designed to redistribute pressure, thereby reducing internal tissue pressure and shear.
