Abstract
This study developed two sets of novel trackball input devices operated by two hands with no space constraints, and required a series of experiments. Besides, the performances of the two newly-developed devices are significantly better than both existing trackball input devices in several tasks. However, the results of stability assessment tests show that the ability of a mouse to control the cursor is still greater than all the other devices. In physical observation part, wrist extension and ulnar deviation were measured while using Jack-1 and Jack-2, and showed apparently slighter than all the other devices.
