How a Diverse Research Ecosystem Has Generated New Rehabilitation Technologies: Review of NIDILRR’s Rehabilitation Engineering Research Centers

Over 50 million United States citizens (1 in 6 people in the US) have a developmental, acquired, or degenerative disability. The average US citizen can expect to live 20% of his or her life with a disability. Rehabilitation technologies play a major role in improving the quality of life for people with a disability, yet widespread and highly challenging needs remain. Within the US, a major effort aimed at the creation and evaluation of rehabilitation technology has been the Rehabilitation Engineering Research Centers (RERCs) sponsored by the National Institute on Disability, Independent Living, and Rehabilitation Research. As envisioned at their conception by a panel of the National Academy of Science in 1970, these centers were intended to take a “total approach to rehabilitation”, combining medicine, engineering, and related science, to improve the quality of life of individuals with a disability. Here, we review the scope, achievements, and ongoing projects of an unbiased sample of 19 currently active or recently terminated RERCs. Specifically, for each center, we briefly explain the needs it targets, summarize key historical advances, identify emerging innovations, and consider future directions. Our assessment from this review is that the RERC program indeed involves a multidisciplinary approach, with 36 professional fields involved, although 70% of research and development staff are in engineering fields, 23% in clinical fields, and only 7% in basic science fields; significantly, 11% of the professional staff have a disability related to their research. We observe that the RERC program has substantially diversified the scope of its work since the 1970’s, addressing more types of disabilities using more technologies, and, in particular, often now focusing on information technologies. RERC work also now often views users as integrated into an interdependent society through technologies that both people with and without disabilities co-use (such as the internet, wireless communication, and architecture). In addition, RERC research has evolved to view users as able at improving outcomes through learning, exercise, and plasticity (rather than being static), which can be optimally timed. We provide examples of rehabilitation technology innovation produced by the RERCs that illustrate this increasingly diversifying scope and evolving perspective. We conclude by discussing growth opportunities and possible future directions of the RERC program

These people rely on sign language, but for effective communication, it is expected that others can understand sign language. Learning sign language is a challenge for those with no impairment. Another challenge is to have a system in which hand gestures of different languages are supported. In this manuscript, a system is presented that provides communication between deaf and mute (DnM) and non-deaf and mute (NDnM). The hand gestures of DnM people are acquired and processed using deep learning, and multiple language support is achieved using supervised machine learning. The NDnM people are provided with an audio interface where the hand gestures are converted into speech and generated through the sound card interface of the computer. Speech from NDnM people is acquired using microphone input and converted into text. The system is easy to use and low cost.

Development and Evaluation of an Assistive Prompting System for People with Traumatic Brain Injury

Cognitive deficits in executive functioning are among the most frequent sequelae after traumatic brain injury (TBI) at all levels of severity. Due to these functional deficits in cognition, individuals with TBI often experience difficulties in performing instrumental activities of daily living (IADL), especially those IADLs that involve a sequence of goal-directed actions. We obtained updated information on the use of assistive technology for cognition (ATC) through a survey study among twenty-nine participants with TBI. Results highlighted the needs to support the development and evaluation of ATC in assisting multi-step tasks. Cooking tasks were selected as a representative for they are cognitively demanding and have been identified essential for living independently. With the recent advance in sensing and smart home technologies, it’s possible to provide context-aware prompts with minimal user inputs. However, limited information is known regarding what types of context-aware prompts are really needed by people with TBI in completing cooking tasks. We compared the effectiveness and usability of current available prompting methods (e.g. paper-based prompting method and user-controlled method) among ten individuals with TBI in their home kitchens. We categorized the nature of problems faced by end-users with both prompting methods in cooking tasks and proposed relevant context-aware solutions. A test-bed Cueing Kitchen with sensing and prompting elements was developed to address these identified needs and to evaluate the feasibility of context-aware ATC interventions in assisting people with TBI with kitchen activities. Sixteen individuals with TBI participated in the study. Results showed that comparing to the conventional user-controlled method, the automatic method decreased the amount of external assistance required by participants, received higher ratings in perceived ease-of-use, and was helpful for decreasing user stress levels. However, the user-controlled method showed strengths in offering participants more flexibility and control on the timing of prompts. The contributions from this dissertation not only developed a context-aware prompting testbed and evaluated the feasibility of an automatic system, but also advanced the guidelines and potential solutions for future development of assistive prompting technology for people with cognitive impairments in sequential tasks
