早前的研究表明，触觉反馈对触摸屏小部件的所有指标都有好处：性能、可用性和用户体验。在我们目前的研究中，我们的目标是更深入地理解虚拟按钮的触觉点击的特征。更具体地说，我们想要找到一种触感点击，用手指使用是最愉快的。我们在一个小型移动触摸屏上使用了两种执行器解决方案：压电执行器或标准振动电机。我们进行了三个实验：第一个和第二个实验的目的是找到最令人愉快的触觉反馈，分别与压电致动器或振动电机，第三个结合并比较了前两个实验的结果。前两个实验的结果显示触觉点击的感知愉悦度存在显著差异，我们在没有触觉反馈的情况下使用了这些最愉悦的点击进行对比实验。我们的发现证实了早期研究的结果，即当用手指使用虚拟按钮时，无论触觉反馈背后的技术如何，触觉反馈优于非触觉条件。另一项发现表明，用户认为用压电致动器完成的反馈比基于振动电机的反馈稍微令人愉快，尽管在统计上没有显著性。这些结果表明，有可能修改虚拟按钮触觉点击的特征，使其更令人愉快，另一方面，这一知识可以帮助设计师创造更好的触摸屏虚拟按钮和键盘。
Earlier research has shown the benefits of tactile feedback for touch screen widgets in all metrics: performance, usability and user experience. In our current research the goal was to go deeper in understanding the characteristics of a tactile click for virtual buttons. More specifically we wanted to find a tactile click which is the most pleasant to use with a finger. We used two actuator solutions in a small mobile touch screen: piezo actuators or a standard vibration motor. We conducted three experiments: The first and second experiments aimed to find the most pleasant tactile feedback done with the piezo actuators or a vibration motor, respectively, and the third one combined and compared the results from the first two experiments. The results from the first two experiments showed significant differences for the perceived pleasantness of the tactile clicks, and we used these most pleasant clicks in the comparison experiment in addition to the condition with no tactile feedback. Our findings confirmed results from earlier studies showing that tactile feedback is superior to a nontactile condition when virtual buttons are used with the finger regardless of the technology behind the tactile feedback. Another finding suggests that the users perceived the feedback done with piezo actuators slightly more pleasant than the vibration motor based feedback, although not statistically significantly. These results indicate that it is possible to modify the characteristics of the virtual button tactile clicks towards the most pleasant ones, and on the other hand this knowledge can help designers to create better touch screen virtual buttons and keyboards.
