This study explores users' tactile sensitivity and perceptual thresholds in a virtual environment by utilizing electrovibration tactile feedback and generating tactile stimuli with different waveform, frequency, and amplitude characteristics through two psychophysical experiments. The significance and potential of studying tactile perceptual thresholds can lead to improved haptic experiences in VR applications.
Haptic sensation plays an important role in providing physical information to users in both real environments and virtual environments. To produce high-fidelity haptic feedback, various haptic devices and tactile rendering methods have been explored in myriad scenarios, and perception deviation between a virtual environment and a real environment has been investigated. However, the tactile sensitivity for touch perception in a virtual environment has not been fully studied; thus, the necessary guidance to design haptic feedback quantitatively for virtual reality systems is lacking. This paper aims to investigate users' tactile sensitivity and explore the perceptual thresholds when users are immersed in a virtual environment by utilizing electrovibration tactile feedback and by generating tactile stimuli with different waveform, frequency and amplitude characteristics. Hence, two psychophysical experiments were designed, and the experimental results were analyzed. We believe that the significance and potential of our study on tactile perceptual thresholds can promote future research that focuses on creating a favorable haptic experience for VR applications.
