振动电机是广泛用于在触觉交互、虚拟现实、人机交互和游戏中产生振动的致动器。振动电机具有价格低廉、体积小等优点，但其内部结构存在一个严重的缺陷，即其输出的振幅和频率都受电压的控制。使用心理物理学中的绝对幅度估计范例，我们先前已经获得了从所施加的电压到用户感知的振动幅度的输入输出（I/O）关系。基于其逆I/O关系，本文提出了一种振动渲染方法，允许用户以感知透明的方式命令振动电机。使用该渲染方法，可以正确地理解振动命令（以电压为单位）对用户感知的影响，从而允许更有效的触觉交互振动设计。我们还实现了一个原型的图形化振动编辑器的感知透明的振动渲染方法被纳入。振动编辑器可以帮助用户在她/他利用图形音频编辑器操纵声音时容易地设计振动电机的振动效果，并且还可以清楚地预测由所产生的振动引起的用户的感知。
The vibration motor is an actuator widely used for generating vibrations in haptic interaction, virtual reality, human-computer interaction, and gaming. Whereas the vibration motor has many advantages such as low price and small size, its internal structure brings a critical limitation: its output has correlated amplitude and frequency both controlled by voltage applied to the motor. Using the absolute magnitude estimation paradigm in psychophysics, we have previously obtained an Input-Output (I/O) relation from the applied voltage to vibration magnitude perceived by the user. Based on its inverse I/O relation, this paper addresses a vibration rendering method that allows the user to command the vibration motor in a perceptually transparent manner. Using the rendering method, the effects of vibration commands (in voltage) on the user's percept can be correctly understood, allowing more effective vibration design for haptic interaction. We have also implemented a prototype graphical vibration editor into which the perceptually transparent vibration rendering method is incorporated. The vibration editor can assist the user to easily design vibration effects for the vibration motor as s/he manipulates sounds with a graphical audio editor and to clearly predict the user's percept induced from the resulting vibrations as well.
