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 …

Locomotion Vault: the Extra Mile in Analyzing VR Locomotion Techniques

Numerous techniques have been proposed for locomotion in virtual reality (VR). Several taxonomies consider a large number of attributes (e.g., hardware, accessibility) to characterize these techniques. However, finding the appropriate locomotion …

PrendoSim: Proxy-Hand-Based Robot Grasp Generator

The synthesis of realistic robot grasps in a simulated environment is pivotal in generating datasets that support sim-to-real transfer learning. In a step toward achieving this goal, we propose PrendoSim, an open-source grasp generator based on a …

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 …

Virtual grasping feedback and virtual hand ownership

In this work, we investigate the influence of different visualizations on a manipulation task in virtual reality (VR). Without the haptic feedback of the real world, grasping in VR might result in intersections with virtual objects. As people are …

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 …

The Effect of Hand Size and Interaction Modality on the Virtual Hand Illusion

Most commercial virtual reality applications with self avatars provideusers with a 'one-size fits all' avatar. While the height of this body may be scaled to the user's height, other body proportions, such as limb length and hand size, are rarely …

Peri-personal space as a prior in coupling visual and proprioceptive signals

It has been suggested that the integration of multiple body-related sources of information within the peri-personal space (PPS) scaffolds body ownership. However, a normative computational framework detailing the functional role of PPS is still …

Touch with foreign hands: The effect of virtual hand appearance on visual-haptic integration

Hand tracking and haptics are gaining more importance as key technologies of virtual reality (VR) systems. For designing such systems, it is fundamental to understand how the appearance of the virtual hands influences user experience and how the …
