Physical Disabilities, Powered Wheelchair, Assistive Technologies, Developing Countries


Physical disabilities have always been a big issue in our communities. Ageing, sickness, and other variables have all had a role in the creation of these issues. That is why Powered wheelchairs were designed to aid people with physical disabilities. Wheelchair users have been exposed to a variety of assistive technologies designed to improve their mobility. As a result, different assistive technologies have recently played a significant role in assisting wheelchair users with movement, this is because technology changes so quickly. The recent trendy of assistive technologies include the joystick, brain-computer interface, voice recognition, tongue drive system, eye tracer, and sip and puff. However, some of the most beneficial assistive technologies become difficult to utilize due to technological gaps among individuals in particular nations. The objective of this research is to study and review the comparative study of these assistive technologies for Physical Disabilities. In the study, tongue drive system, eye tracer, voice recognition, and sip and puff technologies are compared to joystick assistive technology. The comparison is made based on selected parameters including usability commands, fatigue, response time, information transfer rate, effects, and costs. Based on the review, the researchers propose the design of appropriate wheelchairs with assistive technology for developing countries.
