Abstract
This study investigated the influence of the layout of control and display areas of the haptic interface on the performance of word/number input task. Based on QWERTY/numeric keyboards, we designed several schemes of the haptic interface, and developed the haptic interaction software. Nineteen subjects participated in the test, and finished word/number input tasks on the different haptic interfaces; we recorded their task completion time and accuracy, and subjective ratings are recording and analyzed. Results show that the input speed and accuracy of the subjects on the several haptic interfaces do not have significant difference. However, from the subject ratings, we found the subjects favor the haptic interface with the keyboards on the right side of the interface. Chinese character input method can influence task performance significantly. The current study can provide support for the development of relevant ergonomic requirement of haptic interface in the space station.
