    A Comparative Study of Assistive Technologies for Physically challenged peoples for usability of Powered Wheelchair Mobility Aid
    (International Journal of Advances in Scientific Research and Engineering (ijasre), 2022-01) Rwegoshora, Florian; Leo, Judith; Kaijage, Shubi
    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 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 review, the researchers propose the design of appropriate wheelchairs with assistive technology for developing countrie

    Enhanced safety and automated wheelchair for patients with mobility disability: a case study of mount Meru referral hospital, Arusha, Tnzania
    (NM-AIST, 2023-07) Rwegoshora, Florian
    Physical disability remains a challenging problem in Tanzania. The number of people with physical disabilities is increasing every day for a variety of reasons. A wheelchair is one of the devices that assists these people in their daily lives. Various wheelchair designs have been developed, but the prevailing issue is that the existing systems continue to fall short of meeting the needs of the users. There is a great need for a design that can meet some of these people's needs, with safety as a top priority. To address these issues, the study intends to develop an enhanced safety and automated wheelchair for patients with mobility disabilities. The proposed system was a solar-powered wheelchair with some unique safety features for wheelchair users. The wheelchair was built with a joystick for mobility, an MQ-2, a Global System of Mobile communication (GSM), a Global Positioning System (GPS), an Ultrasonic sensor, a buzzer, a pushbutton, a solar panel, a lead-acid battery, and an Atmega 328P processor. Based on some of the previously mentioned important components, the system was able to detect fire once by making a sound via the buzzer, and family members were able to obtain any message if the wheelchair user was in danger simply by pressing the push button. Furthermore, the system was capable of tracking location based on wheelchair user consent and detecting obstacles within a 10cm range. The newly built prototype has a quick response time while maneuvering around with the joystick, and solar power can last for less than 3 hours
