Systems and methods for delivering a plurality of haptic effects

A haptic device including an active element and a plurality of passive elements coupled to the active element. Each passive element has a respective response to a wave transmitted by the active element, and is configured to cause a respective haptic …

Systems and methods for delivering a plurality of haptic effects

A haptic device including a magnet, a rigid and conductive material arranged with respect to the magnet so as to create a gap between the magnet and the rigid and conductive material is disclosed. The haptic device is configured such that a magnetic …

Tactile Echoes: Multisensory Augmented Reality for the Hand

Touch interactions are central to many human activities, but there are few technologies for computationally augmenting free-hand interactions with real environments. Here, we describe Tactile Echoes, a finger-wearable system for augmenting touch …

The Predictive Perception of Dynamic Vibrotactile Stimuli Applied to the Fingertip

Because the world is dynamic in nature, sensory predictions are invariably important to successful interaction with it. The current experiment examined the influence of dynamic frequency information on the associated perceptions of simple geometric …

Methods, devices, and systems for creating localized haptic stimulations on a user

A method of creating localized haptic stimulations on a user includes a wearable device including a plurality of transducers that can each generate one or more waves that propagate away from the wearable device through a medium. The method includes …

Exogenous cueing of visual attention using small, directional, tactile cues applied to the fingertip

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 …

Perceptual Limits of Visual-Haptic Simultaneity in Virtual Reality Interactions

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 …

Tactile Echoes: A Wearable System for Tactile Augmentation of Objects

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 …

The frequency of tactile adaptation systematically biases subsequent frequency identification

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 …

An Experimental Setup to Test Dual-Joystick Directional Responses to Vibrotactile Stimuli

In this paper we investigate the influence of the location of vibrotactile stimulation in triggering the response made using two handheld joysticks. In particular, we compare performance with stimuli delivered either using tactors placed on the palm …
