“…Without adding much complexity to the system, tangibles enable natural object manipulations in VR and provide shape and other physical sensations (e.g., weight, stiffness). They only require adequate tracking of the props [21] or prior calibration and VE modelling [22] combined with tracking of the user. Yet, passive haptics can become unwieldy for representing complex VEs because each virtual object requires its own tangible counterpart.…”

Rich, informative and realistic haptic feedback is key to enhancing Virtual Reality (VR) manipulation. Tangible objects provide convincing grasping and manipulation interactions with haptic feedback of e.g., shape, mass and texture properties. But these properties are static, and cannot respond to interactions in the virtual environment. On the other hand, vibrotactile feedback provides the opportunity for delivering dynamic cues rendering many different contact properties, such as impacts, object vibrations or textures. Handheld objects or controllers in VR are usually restricted to vibrating in a monolithic fashion. In this paper, we investigate how spatialiazing vibrotactile cues within handheld tangibles could enable a wider range of sensations and interactions. We conduct a set of perception studies, investigating the extent to which spatialization of vibrotactile feedback within tangible objects is possible as well as the benefits of proposed rendering schemes leveraging multiple actuators in VR. Results show that vibrotactile cues from localized actuators can be discriminated and are beneficial for certain rendering schemes.

“…1) used a UR5 robot equipped with a 3D-printed end-effector acting as a tray for a single cylindrical tangible object. The tangible is held in place using passive magnets embedded within its base and the tray, similarly to methods used in [5] and [3]. To ensure co-location, the tangible object is tracked using a Vive tracker, ensuring accurate reflection of manipulation movements onto the corresponding virtual object.…”

We present "Alfred", a novel haptic paradigm for object manipulation in 3D immersive virtual reality (VR). It uses a robotic manipulator to move tangible objects in its workspace such that they match the pose of virtual objects to be interacted with. Users can then naturally touch, grasp and manipulate a virtual object while feeling congruent and realistic haptic feedback from the tangible proxy. The tangible proxies can detach from the robot, allowing natural and unconstrained manipulation in the 3D virtual environment (VE). When a manipulated virtual object comes into contact with the virtual environment, the robotic manipulator acts as an encounter-type haptic display (ETHD), positioning itself so as to render reaction forces of the environment onto the manipulated physical object. Here, we discuss the concept for this novel approach and present a simplified prototype using a single detachable tangible proxy supported by a UR5 industrial robot. Through illustrative use-cases in VR and a preliminary performance evaluation, we discuss implications for robot control and design of interaction techniques. We show that Alfred is adaptable to a wide range of virtual environments and interaction scenarios, making it a promising approach for haptic-enabled manipulation in VR, although system latency is a limitation that still remains to be addressed.

“…In particular, hand tracking increases users' immersion by allowing the XR systems to detect when users "touch" a virtual object, leading to more responsive mixed environments. Touching objects in XR has led to augment scenarios in di erent contexts: daily-life usage [24], entertainment [7], industry [23], and medicine [19].…”
