“…They tested the effect of simultaneous presentation in single-finger contact and two-finger grasping and showed that the addition of cutaneous sensory information made the virtual object stiffer. Zhu et al (2022) developed a handheld device that can control the shape and thickness of a surface made of brass tape, presenting various levels of softness. They demonstrated that it enhances the realism of VR compared to vibration feedback alone.…”

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.

“…Similarly, Takahashi and Kim used 3D-printed hairs to present the roughness and stiffness of fur [21]. Zhu et al developed TapeTouch, a display that allows users to experience touching soft objects such as pillows and human ears [22]. The display is capable of providing users with multiple variations of shape and levels of softness.…”

Things that people desire to touch in daily life are known to be limited to a number of specific targets (e.g., cats). The utilization of haptic displays to provide the experience of touching such desired targets is expected to enhance people's quality of life. However, it is currently unclear which haptic properties (e.g., hardness and weight) of desired targets should be rendered with haptic displays, and how they should be rendered. To address these issues, we conducted an experiment with 600 Japanese participants via crowdsourcing. From among the 600 participants, we identified potential users of haptic displays and analyzed their responses for each target. For each desired target, we identified the haptic properties in relation to which a "need for consistency" was felt by potential users between their expectations and actual impressions during touching. We also identified the haptic properties in relation to which a "biased impression" was held by potential users for each target. For example, potential users expected cats to be soft, and therefore the actual impression of softness that is experienced during touching should be consistent with this expectation. Our results provide insights into the design of haptic displays for realizing desired touch experiences.

“…The modification of a virtual objects' structure, its scaling or deformation, is defined in [13] as an Edition task. Rendering a hand-object edition interaction is qualified as palpation when involving a single contact [21,38,53]; or a compliance manipulation [21,29] when involving in-hand manipulations, such as a grasping task.…”

Compliant Stiff Compliant StiffBefore Deformation After DeformationVirtual Environment Sponge Tomato Matchbox Plastic Bottle LockFig. 1: When Tangibles Become Deformable: In the virtual environment, objects are displayed before and after being compressed, following a compliance-stiffness continuum (sponge, tomato, matchbox, water bottle, lock). In the real environment, a user is compressing a tangible object. Using pseudo-stiffness, she perceives this same range of stiffness, while only grasping a noncompressible object. We investigate the range of compliance and stiffness that can be elicited on a non-compressible tangible object.
