We introduce a novel soft exoskeleton glove capable of generating human-like finger joint movements with little constraints on volitional motions. Four pneumatic artificial muscles (approx. 2.5 mm in diameter and less than 2 g weight) were attached to each finger. They form two antagonistic pairs of muscles (i.e. flexor and extensor) and thereby enable the control of several postures of each finger independently. Implementing this structure for all five digits resulted in a hand exoskeleton with 20 DOFs for one hand. This architecture was designed similar to the human anatomy of the forearm muscle, which eventually ensured supporting a natural, unconstrained hand motion. Our system is capable of generating a pressing force of approx. 8 N as a static force and can manipulate a finger to perform high-speed tapping at approx. 10 Hz. Finally, we describe a semi-automatic fitting system that helps to attach the glove easily to the user’s body. Early investigations indicate that the basic technology of our system can contribute domains that need to provide physical force feedback and posture correction to the user’s fingers.

The goal of this work is to establish the range of visual-haptic asynchronies that go unnoticed when touching an object. To perform a psychophysical study, however, we would need asynchronous visual-haptic stimuli, but because the contact of the finger with a real object inevitably creates synchronized haptic feedback, here we employ instead a virtual reproduction of the interaction. Participants immersed in a realistic Virtual Reality environment tapped on a virtual object with their index while viewing a fully articulated representation of their hand. Upon tapping, they received haptic feedback in the form of vibration at their fingertip. After each tap, participants judged whether they perceived the view of the contact and the haptic signal to be synchronous or asynchronous and they also reported which of the two seemed to happen first. Despite the difference between the two judgments, results indicate that none of the 19 participants could reliably detect the asynchrony if haptic feedback was presented less than 50ms after the view of the contact with an object. The asynchrony tolerated for haptic before visual feedback was instead only 15ms. These findings can be used as guidelines for haptic feedback in hand-based interactions in Virtual Reality.

Wearable haptic devices that convey skin stretch have been used in a broad range of applications, from prosthesis proprioception to language transmission. Despite their prevalence, rigorous evaluation of the perception of skin stretch cues is still ongoing. Prior studies indicate that skin stretch cue presentation velocity may impact cue perception, but we lack quantitative data regarding the impact of skin stretch velocity on cue perceptibility. It is important to understand the impact of presentation velocity to ensure the haptic cues are delivered in the most salient manner. In this paper, the Method of Constant Stimuli and Likert surveys were used to capture the just noticeable difference (JND) and participant impressions for two rotational velocities of the Rice Haptic Rocker. The velocities tested did not affect the JND; however, participants reported the faster speed was easier to discern. This study suggests skin stretch devices can be expected to maintain their perceptual performance at varying actuation speeds, meeting the requirements of a variety of applications.

Motion instruction is indispensable for improving skills such as sports and dance. Presenting force and tactile information to humans makes it possible to directly teach motion information; however, existing research for the lower limbs is primarily for walking navigation, since the degree of freedom is only one in navigating directions. In this study, we propose a system that induces leg movement by rotating three end effectors with servomotors. It is possible to induce both translational and rotational motions of the leg by rotating three end effectors. The slip between the end effector and the skin is a significant issue in displaying force. Thus, we aim to examine the effect of the end effector’s curvature on the slip occurrence. In the experiment, the contact area and the shearing force were evaluated when the curvature of the end effector was changed. We confirmed that the effect of the slip could be lessened by increasing the radius of the end effector curvature.

In recent years, thermal display has been studied intensively in order to represent a more realistic tactile quality of the object. Since human feels the temperature of the air without touching other objects, it is necessary to present thermal sensation in a non-contact manner. Studies on non-contact heat display have been explored; however, few studies have reported on a device that can display cold in a non-contact manner. In this study, we propose a non-contact cold thermal display using a low-temperature heat source—vortex tube, which can generate ultra-low air temperature when supplied with compressed air. We developed a cooling model that relates the flow velocity of cold air with the absorbed heat from skin; we implemented a prototype system that can control the flow velocity of the generated air; and we conducted an experiment to examine the cold sensation that the system can present. Our results revealed that various cold sensations can be generated so that the faster the flow velocity, the colder a user would feel.

We describe the design of and initial tests with the OCTA display – a new haptic interface which utilizes a novel tactile display in the form of eight dynamic triangular panels. The proposed device can render virtual height maps in 2.5D through the manipulation of these panels. Through integration with an optical sensor (similar to a standard computer peripheral mouse) to control cursor position, and the use of custom made software, for generating elevation information, the device varies the shape of the display so that virtual shapes may be explored in real-time. This paper outlines the hardware, software, and operation of the device, and describes a static and dynamic user study. These pilot studies indicate that simple static configurations of the OCTA display can be effectively recognized, with shapes using a 6 mm elevation range exhibiting a 90 % identification rate. The device also yielded a significantly higher dynamic identification rate than a single panel device.

Studies suggest that imbalances in speaking opportunities during meetings often lead to sub-optimal meeting outcomes. These imbalances can be due to a variety of reasons, including people’s perception of speakers and their voice. Indeed, speakers with higher pitched voices were shown to be perceived as having lower leadership ability. In an attempt at countering such voice-pitch related biases, this work introduces BarryWhaptics, a real-time speech-to-haptics conversion system that leverages multimodal perception to alter the listener’s perception of a speaker. The system operates by augmenting human speech with vibration, applying more intense vibrations to voices that would ordinarily be considered low in dominance. Results from a pilot study assessing the influence of the system in a decision-making task demonstrate that it can meaningfully influence how users choose to follow instructions given by one speaker over another.

On a touch surface, providing a local vibrotactile feedback enables multiusers and multitouch interactions. While the vibration propagation usually impedes this localization, we show in this paper that narrow strip-shaped plates constitute waveguides in which bending waves below a cut-off frequency do not propagate. We provide a theoretical explanation of the phenomenon and experimental validations. We thus show that vibrations up to 2 kHz are well confined on top of the actuated area with vibration amplitude over 1 µm that can be felt by the fingers. The principle was validated with piezoelectric actuators of various shapes and a vibration motor.

This paper addresses the potential benefits of multimodal haptic feedback combining vibrotactile and impact stimuli for the target domain of virtual collision simulation. In this hybrid approach, we complement the limitation of each modality with the advantage of the other modality. We present the design of a hybrid device including both vibration and impact actuators and a physics-based rendering method for realistic collision simulation. We also report a user study carried out to comparatively assess the subjective quality of haptic collision rendering using vibration only, impact only, and multimodal (vibration + impact) stimuli. Experimental results demonstrate that our multimodal approach can contribute to critically expanding the dynamic range of virtual collision simulation, especially between highly stiff objects.

In the last decade, entertainment industries have been creating multi-sensory experiences using haptic stimulation delivered via vibro-kinetic (VK) seats that produce vibration and motion coincidental with audiovisual content. However, the effects of VK stimulation during purely auditory experiences remains unclarified. We addressed this scientific shortcoming by investigating the effects of high fidelity VK (HFVK) stimulation, on psychophysiological indices of emotional valence and arousal. The HFVK stimulation was delivered to 24 healthy participants through an HFVK enhanced seat during active music listening. Participants listened to six popular songs randomly chosen from a pool of 15 songs, with the songs presented randomly with or without HFVK stimulation. Psychological emotional valence and arousal were indexed based on two items of the Self-Assessment Manikin (SAM) scale. Physiological emotional valence and arousal were respectively indexed based on micro facial expressions and electrodermal activity. Our results revealed that psychological and physiological valence, and psychological arousal were higher with HFVK stimulation compared to a control condition where the chair was static. A post-experiment questionnaire further revealed greater subjective appreciation for the HFVK stimulation condition compared to the control condition. Overall, our results highlight the potential for HFVK technologies to enhance auditory listening experiences.
