Ungrounded haptic devices for virtual reality (VR) applications lack the ability to convincingly render the sensations of a grasped virtual object's rigidity and weight. We present Grabity, a wearable haptic device designed to simulate kinesthetic pad opposition grip forces and weight for grasping virtual objects in VR. The device is mounted on the index finger and thumb and enables precision grasps with a wide range of motion. A unidirectional brake creates rigid grasping force feedback. Two… 
CLAW: A Multifunctional Handheld Haptic Controller for Grasping, Touching, and Triggering in Virtual Reality
This work describes the design considerations for CLAW, a handheld virtual reality controller that augments the typical controller functionality with force feedback and actuated movement to the index finger, and evaluates its performance through two user studies.
DextrES: Wearable Haptic Feedback for Grasping in VR via a Thin Form-Factor Electrostatic Brake
DxtrES, a flexible and wearable haptic glove which integrates both kinesthetic and cutaneous feedback in a thin and light form factor, is introduced and it is demonstrated that the approach can provide rich haptic feedback under dexterous articulation of the user's hands and provides effective haptic Feedback across a variety of different grasps.
TORC: A Virtual Reality Controller for In-Hand High-Dexterity Finger Interaction
Recent hand-held controllers have explored a variety of haptic feedback sensations for users in virtual reality by producing both kinesthetic and cutaneous feedback from virtual objects. These
Holdable Haptic Device for 4-DOF Motion Guidance
A hand-held kinesthetic gripper that provides guidance cues in four degrees of freedom (DOF) that shows promise for holdable kinesthetic devices for haptic feedback and guidance in applications such as medical training, teleoperation, and virtual reality.
Effect of Cutaneous Feedback on the Perception of Virtual Object Weight during Manipulation
The results indicate that the contact force applied to a virtual object during manipulation can be a function of the perceived object weight, and the additional lateral cutaneous feedback to the force feedback led the participants to feel the virtual object heavier than with only kinesthetic feedback.
ElaStick: A Handheld Variable Stiffness Display for Rendering Dynamic Haptic Response of Flexible Object
ElaStick is presented, a variable-stiffness controller that simulates the dynamic response resulting from shaking or swinging flexible virtual objects that can render stiffness with high precision and granularity in a continuous range between 10.8 and 71.5Nmm/degree.
Bstick: Handheld Virtual Reality Haptic Controller for Hand Rehabilitation
Bstick can be used to create VR services and contents based on five-fingered force feedback using a haptic controller that can independently manage the motions of five fingers, and Unity game engine software that can modify hardware.
Docking Haptics: Extending the Reach of Haptics by Dynamic Combinations of Grounded and Worn Devices
The concept of docking haptics, in which different types of haptic devices are dynamically docked at run time, creates a hybrid system, where the potential feedback depends on the user’s location, to extend the practical utility of haPTics in user interfaces.
Haptic Links: Bimanual Haptics for Virtual Reality Using Variable Stiffness Actuation
The authors' user evaluation results confirm that users can perceive many two-handed objects or interactions as more realistic with Haptic Links than with typical unlinked VR controllers.
DeltaTouch: a 3D Haptic Display for Delivering Multimodal Tactile Stimuli at the Palm
DeltaTouch can potentially bring a new level of immersion of the user in VR and improve the quality of teleoperation of the robot equipped with tactile and force sensors.


Fingertip Tactile Devices for Virtual Object Manipulation and Exploration
It is demonstrated that fingertip skin deformation devices can provide a compelling haptic experience appropriate for virtual reality scenarios involving object manipulation.
Wolverine: A wearable haptic interface for grasping in virtual reality
The Wolverine is a mobile, wearable haptic device designed for simulating the grasping of rigid objects in a virtual reality interface that renders a force directly between the thumb and three fingers to simulate objects held in pad opposition (precision) type grasps.
A wearable skin stretch device for haptic feedback
A wearable haptic feedback device that imparts rotational skin stretch to provide feedback regarding movement of a virtual object for feedback of motion for physical therapy or rehabilitation exercises or proprioceptive feedback for amputees is described.
NormalTouch and TextureTouch: High-fidelity 3D Haptic Shape Rendering on Handheld Virtual Reality Controllers
It is found that haptic feedback significantly increases the accuracy of VR interaction, most effectively by rendering high-fidelity shape output as in the case of mechanically-actuated hand-held controllers.
A Wearable Haptic Display to Present the Gravity Sensation - Preliminary Observations and Device Design
It is found that the deformation of the fingerpads can generate the reliable gravity sensation even when the proprioceptive sensation on the wrist or arm is absent, implying that a non-grounded gravity display can be realized by reproducing the fingerpad deformation.
Effects of Grip-Force, Contact, and Acceleration Feedback on a Teleoperated Pick-and-Place Task
The utility of grip-force and high-frequency acceleration feedback in teleoperation systems is supported and motivates further improvements to fingertip-contact-and-pressure feedback.
The hRing: A wearable haptic device to avoid occlusions in hand tracking
A novel wearable cutaneous device for the proximal finger phalanx, called "hRing", which consists of two servo motors that move a belt placed in contact with the user's finger skin that improves the performance and perceived effectiveness of the considered task of 20% and 47% with respect to not providing any force feedback, respectively.
Extending Haptic Device Capability for 3D Virtual Grasping
The presented device is desktop based, and has been designed to maximise the haptic workspace while offering the ability to grasp and manipulate virtual objects, which is a function that current commercial interfaces are limited in providing.
Shifty: A Weight-Shifting Dynamic Passive Haptic Proxy to Enhance Object Perception in Virtual Reality
It is shown that Shifty can enhance the perception of virtual objects changing in shape, especially in length and thickness, and specific combinations of haptic, visual and auditory feedback during the pick-up interaction help to compensate for visual-haptic mismatch perceived during the shifting process.
