“…Bucking and restitution are the most important events for button click sensations [21], and the accelerations between the two events are close to zero. Using an amplitude threshold of 0.2 G (much higher than the corresponding human absolute threshold [19]), the two data segments are extracted from each measurement.…”

“…This finding is analogous to the significance of buckling in real button responses. For instance, in [21] where a physical button simulator that produced actual strokes was used, the buckling or restitution force was the most decisive factor for button click realism. No consideration was given to the time elapsed before the buckling or restitution occurs.…”

“…On the other hand, the realism of button click sensations can also be an important measure. Tashiro et al divided the button click process into a push step including buckling and a release step including restitution and developed a button rendering system using an ultrasonic vibration actuator [21]. They varied the friction coefficient between a contact plate and a user's fingertip based on the squeeze film effect to simulate the bucking and restitution phenomena.…”

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 voicecoil 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.

“…Vibration, as a low-cost substitute for force feedback, is commonly used to simulate tactile feelings of textures for interactive devices and is proven to be an effective means of conveying tactile information [23,30,31]. Vibration feedback is currently available in off-the-shelf consumer devices such as tablet computers and smartphones.…”

Fig. 1. Our proposed method modulates the fine roughness perception of vibrotactile textured surfaces using pseudo-haptic effect. Our user study showed that users felt the surface rougher in response to a parameter configuration of visual feedback.Abstract-Playing back vibrotactile signals through actuators is commonly used to simulate tactile feelings of virtual textured surfaces. However, there is often a small mismatch between the simulated tactile feelings and intended tactile feelings by tactile designers. Thus, a method of modulating the vibrotactile perception is required. We focus on fine roughness perception and we propose a method using a pseudo-haptic effect to modulate fine roughness perception of vibrotactile texture. Specifically, we visually modify the pointer's position on the screen slightly, which indicates the touch position on textured surfaces. We hypothesized that if users receive vibrational feedback watching the pointer visually oscillating back/forth and left/right, users would believe the vibrotactile surfaces more uneven. We also hypothesized that as the size of visual oscillation is getting larger, the amount of modification of roughness perception of vibrotactile surfaces would be larger. We conducted user studies to test the hypotheses. Results of first user study suggested that users felt vibrotactile texture with our method rougher than they did without our method at a high probability. Results of second user study suggested that users felt different roughness for vibrational texture in response to the size of visual oscillation. These results confirmed our hypotheses and they suggested that our method was effective. Also, the same effect could potentially be applied to the visual movement of virtual hands or fingertips when users are interacting with virtual surfaces using their hands.

“…In the former one, the frictional force is attenuated by mechanical actuation of the touch screen at its ultrasonic resonance frequency [1]. By modulating the vibration amplitude, rendering different tactile effects such as textures [2] and key-click [3] is possible. In electrovibration, on the other hand, the friction force is altered via electrostatic forces [4], which are generated by applying an alternating voltage signal to the conductive layer of a surface capacitive touch screen.…”

Future touch screen applications will include multiple tactile stimuli displayed simultaneously or consecutively to single finger or multiple fingers. These applications should be designed by considering human tactile masking mechanism since it is known that presenting one stimulus may interfere with the perception of the other. In this study, we investigate the effect of masking on tactile perception of electrovibration displayed on touch screens. Through conducting psychophysical experiments with nine subjects, we measured the masked thresholds of sinusoidal electrovibration bursts (125 Hz) under two masking conditions: simultaneous and pedestal. The masking stimuli were noise bursts, applied at five different sensation levels varying from 2 to 22 dB SL, also presented by electrovibration. For each subject, the detection thresholds were elevated as linear functions of masking levels for both masking types. We observed that the masking effectiveness was larger with pedestal masking than simultaneous masking. Moreover, in order to investigate the effect of tactile masking on our haptic perception of edge sharpness, we compared the perceived sharpness of edges separating two textured regions displayed with and without various masking stimuli. Our results suggest that sharpness perception depends on the local contrast between background and foreground stimuli, which varies as a function of masking amplitude and activation levels of frequency-dependent psychophysical channels.
