A Study of Performance on Multi-touch Gesture for Multi-haptic Feedback

Abstract

With the popularization of mobile devices and the trends in population aging, it becomes important to consider aging issues on the development of mobile devices. Many studies have shown that mobile devices with haptic feedback provide users with the better user experience. This study combines pinch open/close and clockwise/counter-clockwise rotation gesture with four different types of vibration modes, and compares the task completion time and idle ratio of each. The aim is to increase the haptic feedback variety and explore haptic feedback technology applicability in the future. The result shows that the vibration mode can shorten the average operation time compared to the non-vibration mode, wherein the lasted-vibration mode has a significant shortening of the operation time. While the ratio of the idle time, there has a significant different between both non-vibration lasted vibration (p-value = 0.04) and non-vibration versus reminded-vibration (p-value = 0.039) in pinch open gesture.
