Using Performance Evaluation of Touchpad and Touchscreen

Abstract— Digital pen or Stylus is extensively used in multimedia design such as graphic and animation design. In business, it has been used for electronic signature. Digital pen technology can be separated by the input device as a touchscreen and a touchpad. Both input devices are different in visual perception. A touchpad is an indirect visual perception device often has a cursor lag problem that lead to lower performance than a direct visual perception device as touchscreen. Moreover, the display size is another important factor of touchpad using, a smaller display is harder to percept and control. In this research, there were two objectives which were 1. to compare the working performance between touchscreen and touchpad, and 2. to evaluated the effect of display sizes while using touchpad on working performance. There were eight participants used a digital pen to perform tapping and dragging tasks following fitts’ law and steering law concepts. The results showed that the touch screen usage had a better performance than touchpad usage in both tasks. The display size of touchpad usage effected on the using performance in both tasks. The smaller display size decreased the working performances.

Index Terms— touchpad, touchscreen, tapping, dragging.
