Trackball is one of the common input devices for cerebral palsy. Using trackball can improve the limited of their hand ability. Mostly the products are design with the big-trackball device from abroad, or just use the general trackball instead. However, in Taiwan, they are not specially design for disabilities. The mouse for disabilities is just the refit or selection from general one by the clinical experience. Once the clinical experts made the refit error, the trackball device will be useless or even harm the disabilities. Therefore, as an industrial design’s study, this research analyze the trackball device from cerebral palsy’s needs. Through Quality function deployment　(QFD), the research method, can shorten the cognitive differences between the users and the device providers. So the device refit expert or designer can take the outcome as consulting reference. First, using Literature Reviews and participant observation to collect and define the practical experience of cerebral palsy in the operation to confirm the problem point and the needs. Then interview the experts to find the induction quality elements, functions and mechanism of the engineering from Resource Portal of Assistive Technology. Finally, the result of this research is transforming the users' needs systematically into engineering to Assist the Trackball Input Device Improvement. Summed up the trackball design focus, functional focus, mechanism focus, and finally put forward the bottleneck technique.
