“…This provides the illusion of using a stick to interact with virtual objects in VR. ElastOscillation [16] uses six elastic bands and a proxy to provide 3D force feedback for damped oscillation. The elastic bands' extension distances are controlled by motors to achieve multilevel force feedback.…”

“…However, the magnitude of resistive force between the controllers depends on the hands' movement. Therefore, we performed a force perception study as in [16,19] instead of a JND study. Although we focus on exploring PAF in this paper, we must base on the results of this study to obtain the proper resistive and impact force stimuli to further investigate the PAF distinguishability.…”

“…Two VR scenes were built for the resistive force and impact ( Figure 5), respectively. Based on the study design in [16,19], the participants matched the visual feedback to the perceived force feedback. For resistive force, we rendered virtual ElastiLinks controllers connected by an elastic band instead of rendering the physical force links.…”

Force feedback is commonly used to enhance realism in virtual reality (VR). However, current works mainly focus on providing different force types or patterns, but do not investigate how a proper point of application of force (PAF), which means where the resultant force is applied to, affects users' experience. For example, users perceive resistive force without torque when pulling a virtual bow, but with torque when pulling a virtual slingshot. Therefore, we propose a set of handheld controllers, ElastiLinks, to provide force feedback between controllers with dynamic PAFs. A rotatable track on each controller provides a dynamic PAF, and two common types of force feedback, resistive force and impact, are produced by two links, respectively. We performed a force perception study to ascertain users' resistive and impact force level distinguishability between controllers. Based on the results, we conducted another perception study to understand users' distinguishability of PAF offset and rotation differences. Finally, we performed a VR experience study to prove that force feedback with dynamic PAFs enhances VR experience.

Haptic controllers have an important role in providing rich and immersive Virtual Reality (VR) experiences. While previous works have succeeded in creating handheld devices that simulate dynamic properties of rigid objects, such as weight, shape, and movement, recreating the behavior of fexible objects with different stiffness using ungrounded controllers remains an open challenge. In this paper we present ElaStick, a variablestiffness controller that simulates the dynamic response resulting from shaking or swinging fexible virtual objects. This is achieved by dynamically changing the stiffness of four custom elastic tendons along a joint that effectively increase and reduce the overall stiffness of a perceived object in 2-DoF. We show that with the proposed mechanism, we can render stiffness with high precision and granularity in a continuous range between 10.8 and 71.5Nmm/ •. We estimate the threshold of the human perception of stiffness with a just-noticeable difference (JND) study and investigate the levels of immersion, realism and enjoyment using a VR application.

Immersive analytics often takes place in virtual environments which promise the users immersion. To fulfill this promise, sensory feedback, such as haptics, is an important component, which is however not well supported yet. Existing haptic devices are often expensive, stationary, or occupy the user’s hand, preventing them from grasping objects or using a controller. We propose PropellerHand, an ungrounded hand-mounted haptic device with two rotatable propellers, that allows exerting forces on the hand without obstructing hand use. PropellerHand is able to simulate feedback such as weight and torque by generating thrust up to 11 N in 2-DOF and a torque of 1.87 Nm in 2-DOF. Its design builds on our experience from quantitative and qualitative experiments with different form factors and parts. We evaluated our prototype through a qualitative user study in various VR scenarios that required participants to manipulate virtual objects in different ways, while changing between torques and directional forces. Results show that PropellerHand improves users’ immersion in virtual reality. Additionally, we conducted a second user study in the field of immersive visualization to investigate the potential benefits of PropellerHand there. Graphical abstract
