- Abstract
- 'Click' and 'Tap' are one of the most commonly used gestures UI on touchscreen. There were many studies that aimed to provide realistic tactile feedback when user touched a graphic object on touchscreen. In this study, we analyzed perceived intensity levels of tactile sensation that can be utilized in clicking or tapping gesture on touchscreen. Two experiments were conducted to investigate the number of perceived intensity levels. The first was to find the range of accelerations for our new haptic device. The second experiment was to measure the number of intensity levels that can be reliably identified in the acceleration ranges. Four stimuli were used in this experiment. The result showed average information transfer of 1.34 bits for intensity identification, or equivalently, 2.53 correctly identifiable intensity levels. © 2012 Authors.
