The system can potentially be used as a tool to complement conventional rehabilitation approaches of ADL. Implications for rehabilitation Rehabilitation of activities of daily living can be facilitated using computer-assisted approaches. The existing approaches focus on cognitive training rather than the manual skills. A virtual training system with intuitive user interface and force feedback was designed to improve the learning of the manual skills. The study shows that system could be used as a training tool to complement conventional rehabilitation approaches.
Deficiency of hand function presents difficulty to disabled people in various activities of daily living. While rehabilitation training in occupational therapy is helpful for them to cope with their deficiency, the paper presents a virtual realty based system in attempt to provide an alternative approach to complement the conventional methods. The system simulates tasks of daily living in virtual environments and produces real-time interactive graphics and forces to enable trainees to practise the skills in cyberspace. Currently, three tasks are simulated, namely, door opening, water pouring and meat cutting. Visual, audio and haptic cues are produced as guidance in response to user's actions. The performance of the users is recorded automatically on the fly with quantifiable metrics to enable objective analysis of the learning progress. Findings from initial trials with disabled children show that they found it very interesting to use the system and could adapt to the virtual training environment for practicing the tasks. Further study will be conducted to improve system usability and to evaluate the training effectiveness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
