ItemHeight adjustable wheelchair seat design(Georgia Institute of Technology, 2011-07-08) Li, YiranFull time wheelchair users are at a height disadvantage during many function activities, such as transferring or reaching. Retrieving objects from the ground or a higher shelf while seated in the wheelchair can be both difficult and unsafe. Lateral transfers between surfaces at different heights can be difficult and unsafe. Sit-to-stand transfers are made simpler with a higher seat. This research project seeks to assist reach and transfers by designing a system to raise and lower a wheelchair seat over a 4'' range. The project included several needs assessment: 1) by conducting interviews and surveys, identify design needs from different stakeholder groups; 2) analysis of stakeholder groups' feedback and synthesis into design criteria; and 3) creation of design concepts for the adjustable height wheelchair seat; 4) evaluation of the design by setting up heuristic evaluation criteria and perform user testing; 5) design revision design based on user's performance and feedback. The design process included fabricating and testing of various concepts, validating design through user testing, and addresses technology transfer of the device.

ItemThe Impact of Home Modifications and Wheelchair Usability on Activity and Participation(Georgia Institute of Technology, 2011) Harris, Frances ; Yang, Hsiang-Yu ; Sanford, JonThe interaction between mobility device and environment is most important in the home where the majority of wheelchair use occurs (1). Environmental barriers, such as unmet home modification needs, may impact the performance of mobility related activities of daily living (MRADLS) (2,3). This study reports preliminary results from a study measuring the effect of home modifications and wheelchair usability on the activities and participation among 78 people who rely on a wheelchair for the majority of their mobility needs.
