Abstract
En 中文
Vibration motors are widely used for haptic feedback. By generating asymmetric vibrations, they can induce pulling sensations without cumbersome force feedback devices. To fully exploit their potential, an efficient method for synthesizing asymmetric vibration input signals is essential. This article proposes a novel method to control the direction and intensity of pulling sensations via velocity difference (VD), the absolute difference between maximum and minimum vibration velocities, offering new insights into the applications of vibration motors in haptic feedback. The method models the input signal as a superposition of the fundamental wave and its first three harmonics, with their amplitudes and initial phases determined by VD. To ensure accurate VD output, the method compensates for amplitude attenuation and phase shifts introduced by the frequency response of the system, aligning the vibration acceleration profiles with the input signals. A two-alternative forced-choice experiment was conducted, where participants indicated the perceived direction of the pulling sensations. Experimental results show that within 60–200 Hz, VD is a key factor in the directional perception of pulling sensations induced by asymmetric vibration. Compared to jerk difference-based methods, the proposed method significantly improves directional accuracy in generating pulling sensations.
