“…Some studies have used electro-tactile stimuli as wearable devices, presenting them to the fingertips and the entire palm (Lin, et al, 2022;Yao, et al, 2022). Takei et al (2015) attached a film pressure distribution sensor under a film electro-tactile display, measured the pressure applied to each electrode by a pressing finger, and used it as feedback for electrical stimulation. They applied electrical stimulation to the outer edge of the area where pressure was applied and designed the stimulation to spread out in steps as the pressing force increased, representing the spread of the contact area and the sensation of softness.…”

“…A method for presenting softness by changing the contact area using an arrayed electro-tactile display was proposed (Takei, et al, 2015;Yem, et al, 2018). However, no attempts have been made to develop a method that presents softness by combining the force sensation with electrical stimuli, and no quantitative evaluation of the presented stimuli has been performed.…”

To provide realistic tactile sensations in a virtual environment, it is necessary to stimulate both the cutaneous and proprioceptive senses. This study focuses on a realistic method of presenting softness through the use of electro-tactile stimulation. Our system combines a force-feedback device with an electric stimulator to create a soft sensation by applying a reaction force and spreading cutaneous sensation based on the amount of indentation. We measured the change in the contact area of gel samples and used electric stimulation to reproduce the increase in the contact area of the sample. We conducted a psychophysical experiment to evaluate the effectiveness of the combination of cutaneous and force sensations and confirmed that the sensation of softness was enhanced by the simultaneous presentation.

“…Finally, pseudo-forcefeedback has been explored. By changing the contact area of the finger [15,21] or using electro-tactile displays, one can create a softness-like sensation [23,64]. However, this is not central to commodity push-buttons' design.…”

Designing a pushbutton with desired sensation and performance is challenging because the mechanical construction must have the right response characteristics. Physical simulation of a button's force-displacement (FD) response has been studied to facilitate prototyping; however, the simulations' scope and realism have been limited. In this paper, we extend FD modeling to include vibration (V) and velocity-dependence characteristics (V). The resulting FDVV models better capture tactility characteristics of buttons, including snap. They increase the range of simulated buttons and the perceived realism relative to FD models. The paper also demonstrates methods for obtaining these models, editing them, and simulating accordingly. This end-to-end approach enables the analysis, prototyping, and optimization of buttons, and supports exploring designs that would be hard to implement mechanically.

“…Various types of haptic feedback devices have been explored to present the sensation of virtual objects [15]. Object properties such as surface texture and heaviness have been reproduced through technical approaches including Vibro-Tactile Feedback [24,26], or Electro-Stimulation [20,37].…”

While previously proposed hardware on pin-based shape display has improved various technical aspects, there has been a clear limitation on the haptic quality of variable 'force' feedback. In this paper, we explore a novel haptic interaction design space with 'force' controlled shape display. Utilizing high performance linear actuators with current reading functionality, we built a 10 x 5 'force' shape display, named inFORCE, that can both detect and exert variable force on individual pins. By integrating closed-loop force control, our system can provide real-time variable haptic feedback in response to the way users press the pins. Our haptic interaction design space includes volumetric haptic feedback, material emulation, layer snapping, and friction. Our proposed interaction methods, for example, enables people to "press through" computationally rendered dynamic shapes to understand the internal structure of 3D volumetric information. We also demonstrate a material property capturing functionality. Our technical evaluation and user study assesses the hardware capability and haptic perception through interaction with inFORCE. We also discuss application spaces that 'force' shape display can be used for.
