线性振动致动器，例如Alps Electric Co.的Force Reactor或Tactile Labs Inc.的Haptuator。积极地用于向指尖呈现多种触觉。与传统的偏心旋转质量振动电机相比，它们具有高响应性，并且当施加不对称信号时也能够产生伪触觉错觉。然而，这种类型的致动器具有某些设计挑战，例如经由附接到振动质量的弹簧的共振，以及由于质量的有限行进距离而在低频下的有限加速度幅度。在我们的研究中，我们提出了一种新的触觉呈现方法，使用旋转电机的反作用力，在加速过程中发生。利用电机转子本身作为振动质量，使振动质量可以无限制地无限运动。本文报道了使用直流电动机作为振动致动器。结果表明，直流电机的响应时间约为3 ms，这是快于目前的线性振动致动器。振动的峰值振幅在低频（约40 Hz）。我们还发现，直流电机能够提供旋转伪力的感觉。由单个电机产生的振动和伪力的组合允许向指尖呈现广泛的触觉。
Linear vibration actuators such as the Force Reactor from Alps Electric Co. or the Haptuator from Tactile Labs Inc. are actively used to present numerous tactile sensation to the fingertip. They have high responsiveness compared with conventional eccentric rotating mass vibration motors, and are also able to produce pseudo-haptic illusions when asymmetric signals are applied. However, this type of actuator has certain design challenges, such as resonance via the spring attached to the vibration mass, and limited acceleration amplitude at low frequency because of the limited travel distance of the mass. In our study, we propose a new haptic presentation method using the rotational motor's counterforce that occurs during acceleration. We use the rotor of motor itself as the vibration mass, so the mass can move indefinitely without limitation. This paper reports on the use of a DC motor as a vibration actuator. The results show that the response time of a DC motor is about 3 ms, which is faster than current linear vibration actuators. The peak amplitude of vibration is at a low frequency (about 40 Hz). We also found that a DC motor is able to provide a rotational pseudo-force sensation. The combination of vibration and pseudo-force produced by a single motor allows a wide range of haptic presentation to the fingertips.
