在本文中，我们设计了大量（72）的触觉刺激，用于移动设备触摸屏上虚拟按键的确认反馈。研究中使用了两个行业标准的变磁阻执行器（增加质量以获得更强输出的增强型音圈执行器）。输入的设计参数为振幅、持续时间、载波信号、包络函数和致动器。18名参与者根据与物理按钮的相似性和用户偏好的标准来评估模型模式。一个形容词评级任务也伴随着评估设计的触觉效果的主观质量。实验结果揭示了设计真实和有利的按键触觉反馈的几个重要准则。本文的研究结果对通过触觉反馈提高触摸屏上显示的用户界面组件的可用性具有启示意义。
In this paper, we present the design of a large number (72) of tactile stimuli for the confirmation feedback of virtual button presses on the mobile device touchscreen. Two industry standard variable-reluctance actuators (enhanced voice-coil actuators with added mass for stronger output) were used in the study. The design parameters of an input were amplitude, duration, carrier signal, envelope function, and actuator. Eighteen participants evaluated the modeled patterns with the criteria of similarity to physical buttons and user preference. An adjective rating task was also accompanied to assess the subjective quality of the designed tactile effects. Experimental results unveiled several important guidelines for designing realistic and favorable button-click tactile feedback. The findings of this paper have implications for improving the usability of user interface components displayed on a touchscreen by means of haptic feedback.
