Evaluating playability on haptic user interface for mobile gaming

There have been escalating research interests on areas relating to haptic modality in recent years, especially towards mobile devices. However, there seems to be limited studies in determining the relation between haptic user interfaces and its influence on the playability of mobile games. This paper aims to measure playability of mobile games by comparing two different types of haptic interfaces, namely hard and soft keypad, for mobile gaming. The results show that the participants (N=12) scored highest in using a soft keypad (mean = 591.92, SD = 322.57) as compared to playing games using a hard keypad (mean = 471, SD = 359.29). However, this paper highlights that the majority of users prefer using the hard keypad method in virtue of greater player experience with regards to game play.
