Spatiotemporal Haptic Effects from a Single Actuator via Spectral Control of Cutaneous Wave Propagation
IEEE World Haptics Conference
A key challenge in haptic engineering is to design methods for stimulating the skin – a continuous medium with infinitely many degrees of freedom – via practical devices with few degrees of freedom. Here, we show how to use a single actuator to generate tactile stimuli with dynamically controlled spatial extent

Tasbi: Multisensory Squeeze and Vibrotactile Wrist Haptics for Augmented and Virtual Reality
World Haptics
In this work, we present Tasbi, a multisensory haptic wristband capable of delivering squeeze and vibrotactile feedback. The device features a novel mechanism for generating evenly distributed and purely normal squeeze forces around the wrist. Our approach ensures that Tasbi’s six radially spaced vibrotactors maintain position and exhibit consistent skin coupling.

Z-Qualities and Renderable Mass-Damping-Stiffness Spaces: Describing the Set of Renderable Dynamics of Kinesthetic Haptic Displays
IEEE World Haptics Conference
In this paper we define language and definitions to define the renderable set of dynamics that a general kinesthetic haptic display can render to a human operator.

A Balanced Hybrid Active-Passive Actuation Approach for HighPerformance Haptics
IEEE World Haptics Conference
Hybrid actuation approaches for haptic interfaces generally suffer from asymmetry in active and passive torque capabilities. This paper describes the design of a high-performance balanced hybrid haptic device, which addresses the asymmetry by combining a high-power, low-impedance active compliant actuation (series-elastic actuator) with energy absorbing high-force passive actuation in parallel with a fast, low-power secondary active actuation.

Bellowband: A Pneumatic Wristband for Delivering Local Pressure and Vibration
IEEE World Haptics Conference
In this paper we present the design and control of Bellowband, a pneumatic wristband for localized pressure and vibration haptic feedback. The wristband has eight equally spaced pneumatic bellows that extend into the wrist, constructed from layers of polyester thermoplastic polyurethane (TPU), resulting in a flexible, lightweight (11 g) band capable of rendering complex pressure and vibration cues to the user.

Stiffness in Virtual Contact Events: A Non-Parametric Bayesian Approach
IEEE World Haptics Conference
In this study we investigated the use of simple vibrotactile signals to simulate contact with a virtual object. In particular we explored the relation between properties of the signal and the perceived hardness of the object.

Perceptual Limits of Visual-Haptic Simultaneity in Virtual Reality Interactions
IEEE World Haptics Conference
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.

Tactile Echoes: A Wearable System for Tactile Augmentation of Objects
IEEE World Haptics Conference
We present Tactile Echoes, a wearable system for augmenting tactile interactions with any object. This system senses vibrations in the fingertip that are produced by interactions of the finger with a touched object. It processes the vibration signals in real-time via a parametric signal network and returns them to the finger as “Tactile Echoes” of the touch interaction.

The frequency of tactile adaptation systematically biases subsequent frequency identification
IEEE World Haptics Conference
Exposure to a particular sensory stimulation for a prolonged period of time often results in changes in the associated perception of subsequent stimulation. Such changes can take the form of decreases in sensitivity and/or aftereffects. Aftereffects often result in a rebound in the perception of the associated stimulus property when presented with a novel stimulus. The current study sought to determine if such perceptual aftereffects could be experienced following tactile stimulation at a particular frequency.

Exogenous cueing of visual attention using small, directional, tactile cues applied to the fingertip
IEEE World Haptics Conference
The deployment of visual spatial attention can be significantly influenced in an exogenous, presumably bottom-up manner. Traditionally, spatial cueing paradigms have been utilized to come to such conclusions. Although these paradigms have primarily made use of visual cues, spatially correspondent tactile cues have also been successfully employed.
