    In East Africa, individuals with mobility disabilities face significant barriers to participating in educational, social, and public life activities due to the challenging terrains that make basic push-rim wheelchairs ineffective. To address this issue, our team partnered with Kyaro Assistive Tech with the goal of redesigning a wheelchair attachment that allows individuals with lower-body disabilities to traverse East Africa’s often rough terrains more easily and efficiently. Our approach included a thorough examination of existing off-road wheelchair solutions, comprehensive user research, and careful consideration of ethical implications. Following a visit to Tanzania and several weeks of extensive prototyping and analysis, we designed an innovative drivetrain concept featuring a pull-based actuation mechanism that attaches to a standard push-rim wheelchair, and is novel in comparison to traditional wheelchair designs. We selected this concept because of its mechanical advantage and user ergonomics. We also used engineering analysis to assess our design’s efficacy, examining factors such as the human optimum work range and the durability of components. In our final prototype, we encountered operational challenges and were limited to testing in purely off-ground scenarios. Despite this setback, our efforts resulted in a design that is easily repairable and manufacturable in Tanzania, as it utilizes commonly available bicycle and household parts. We also tested our design against high-priority engineering requirements, which revealed that our design significantly reduced the need for body twisting and improved overall user comfort. In future work, we will focus on further ergonomic enhancements and adjusting the gear ratio to reduce the force required by the user to travel on the ground and up an incline. Our project not only addresses immediate mobility challenges but also contributes to the broader conversation on accessible design and the importance of incorporating user-centric principles and local manufacturing capabilities in the development of assistive technologies.

  3. Trends and developments for the future of language education in higher education

    Hershey, Pennsylvania (701 E. Chocolate Avenue, Hershey, Pennsylvania, 17033, USA) : IGI Global, 2021

    "This book provides an overview of the landscape of language education in Higher Education that has been significantly impacted by Covid-19 and Identify the trends and developments of the discipline, prior and post Covid-19 to affect the future development and outlook of language education"--Language education tends to require more face-to-face interaction and longer hours of both teaching and learning. The challenges of ensuring the future and development of the discipline, especially after a time of crisis, is equally unprecedented. A comprehensive overview of the global picture of best practices as well as research in recent times are needed in the field of language education, particularly in higher education settings. The changing nature of language education in terms of its policy, curriculum design, methodology, and innovation is an essential discussion to advance the field. It is critical to explore how a more collaborative, global, and interdisciplinary mindset, as well as technologically driven approaches have emerged through recent years and how it will continue to shape the future development in the field. Trends and Developments for the Future of Language Education in Higher Education captures the current trends and ongoing development within language education through a global picture of the best practices as well as the latest research on language education in higher education settings. The chapters cover changes in policy, curriculum design, methodology, and innovation in the modern language education landscape. While focusing on the current situation of language education and the changes that it has been undergoing, this book also provides information on future development and the overall outlook of language education. This book is ideal for teachers, instructional designers, curricula developers, inservice and preservice teachers, administrators, teacher educators, practitioners, researchers, academicians, and students looking for an overview of the current position of language education in higher education.
