  • Abstract When going out, people with disability usually have to rely on their relatives or friends to drive them in cars or in motorcycles. When getting on or off the transportation, the centers of gravity of wheelchair users always deviate while no proper place to grasp. Their caregivers who help them to move around also encounter a lot of problems. This situation is conflict with the principles of equal use and effort-saving regarding the universal design. This study aimed to figure out a set of design principles for assistive handles in cars to help the wheelchair users easily get on and off the cars.
    Through questionnaire survey, activity analysis, anthropometry, and literature review, a set of design principles for assistive handles in cars was derived. The results of questionnaire survey and activity analysis have indicated the places where the wheelchair users grasp in assisting them to get on and off cars (B pole on the car body, place on the head set of the driver-side passenger, and place above the glove compartment). Then the locations where the assistive handles should be installed were decided accordingly. A set of design principles was set up by integrating literature review with the results mentioned above, and with the dimensions coming from anthropometry. A model was made and used in the validation experiment. 12 males and 18 females were recruited. Collected data was analyzed by independent t-test. On the average, the subjects subjectively thought the assistive handles was significantly easier, safer and more comfortable in aiding them to get on and off car, and the burden of the caregivers was significantly reduced.
    Reliability and validity were analyzed with the data obtained from six subjects who participated in both questionnaire survey and the validation experiments. The results proved the reliability and validity. The assistive handles not only significantly reduce the time spent on getting on and off cars by 40%, but also reduce the average angle of dorsal deviation by 75% and the average angle of ulnar deviation by 60%. Therefore, the chances of getting hurt might be reduced too.
    The findings of this study indicated that the concept of assistive handles put forward by researchers complies with the principles of universal design in effort-saving and in using naturally. It could be applied to more other grasping products. The design principles of assistive handles laid out in this study might be used as a good reference for related designers or manufacturers.
