Physical Variables Underlying Tactile Stickiness during Fingerpad Detachment
One may notice a relatively wide range of tactile sensations even when touching the same hard, flat surface in similar ways. Little is known about the reasons… Read more “Physical Variables Underlying Tactile Stickiness during Fingerpad Detachment”
Tactile Roughness Perception of Virtual Gratings by Electrovibration
Realistic display of tactile textures on touch screens is a big step forward for haptic technology to reach a wide range of consumers utilizing electronic devices on… Read more “Tactile Roughness Perception of Virtual Gratings by Electrovibration”
Fingertip Interaction Metrics Correlate with Visual and Haptic Perception of Real Surfaces
Both vision and touch contribute to the perception of real surfaces. Although there have been many studies on the individual contributions of each sense, it is still… Read more “Fingertip Interaction Metrics Correlate with Visual and Haptic Perception of Real Surfaces”
Effect of Remote Masking on Tactile Perception of Electrovibration
Masking has been used to study human perception of tactile stimuli, including those created on haptic touch screens. Earlier studies have investigated the effect of in-site masking… Read more “Effect of Remote Masking on Tactile Perception of Electrovibration”
A Novel Texture Rendering Approach for Electrostatic Displays
Generating realistic texture feelings on tactile displays using data-driven methods has attracted a lot of interest in the last decade. However, the need for large data storages… Read more “A Novel Texture Rendering Approach for Electrostatic Displays”
Tactile Masking by Electrovibration
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… Read more “Tactile Masking by Electrovibration”
Roughness perception of virtual textures displayed by electrovibration on touch screens
In this study, we have investigated the human roughness perception of periodical textures on an electrostatic display by conducting psychophysical experiments with 10 subjects. To generate virtual… Read more “Roughness perception of virtual textures displayed by electrovibration on touch screens”
Effect of Waveform on Tactile Perception by Electrovibration Displayed on Touchscreens
In this study, we investigated the effect of input voltage waveform on our haptic perception of electrovibration on touch screens. Through psychophysical experiments performed with eight subjects,… Read more “Effect of Waveform on Tactile Perception by Electrovibration Displayed on Touchscreens”
Self-tuning in Sliding Mode Control of High-Precision Motion Systems
In high-precision motion systems, set-point tracking often comes with the problem of overshoot, hence poor settling behavior. To avoid overshoot, PD control (thus without using an integrator)… Read more “Self-tuning in Sliding Mode Control of High-Precision Motion Systems”
