Belt and Whistles: Adding Lower Body Collision Awareness for MR Experiences

A haptic belt for mixed reality that renders collision and proximity cues around the lower body to improve spatial awareness and reduce unintended collisions.

TEXT: Text Entry for XR Trove—Collecting and Analyzing Techniques for Text Input in XR

Text entry for extended reality (XR) is far from perfect, and a variety of text entry techniques (TETs) have been proposed to fit various contexts of use. However, comparing between TETs remains challenging due to the lack of a consolidated …

A methodological framework to assess the accuracy of virtual reality hand-tracking systems: A case study with the Meta Quest 2

A fixed-grid framework for measuring positional error, joint-angle accuracy, and temporal delay in VR markerless hand tracking, demonstrated with Meta Quest 2.

How important are detailed hand motions for communication for a virtual character through the lens of charades?

A set of perceptual experiments testing how changes to virtual-character hand and finger motions affect comprehension, character perception, social presence, and comfort.

Perceived intensities of normal and shear skin stimuli using a wearable haptic bracelet

Our aim is to provide effective interaction with virtual objects, despite the lack of co-location of virtual and real-world contacts, while taking advantage of relatively large skin area and ease of mounting on the forearm. We performed two human …

Robot, pass me the tool: handle visibility facilitates task-oriented handovers

A VR study showing that handle visibility improves perceived holdability and immediate usability during robot-to-human tool handovers.

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 …

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 …
