“…The light weight of the propellers makes them more suitable for VR applications and wearables when compared to flywheels. The wind blaster [27] is an example of a wrist-worn device that provides force feedback using two propellers. PaCaPa [28] offers a simple mechanical handheld device to make indirect interaction with handheld tools in VR more realistic.…”

Most haptic actuators available on the market today can generate only a single modality of stimuli. This ultimately limits the capacity of a kinaesthetic haptic controller to deliver more expressive feedback, requiring a haptic controller to integrate multiple actuators to generate complex haptic stimuli, with a corresponding complexity of construction and control. To address this, we designed a haptic controller to deliver several modalities of kinaesthetic haptic feedback using a single actuator: a flywheel, the orientation of which is controlled by two gimbals capable of rotating over 360 degrees, in combination with a flywheel brake. This enables the controller to generate multiple haptic feedback modalities, such as torque feedback, impact simulation, low-frequency high-amplitude vibrations, inertial effects (the sensation of momentum), and complex haptic output effects such as the experience of vortex-like forces (whirl effects). By combining these diverse haptic effects, the controller enriches the haptic dimension of VR environments. This paper presents the device’s design, implementation, and characterization, and proposes potential applications for future work.

“…Researchers have investigated the potential of haptic devices for everyday use, and we anticipate their incorporation into our daily lives in the near future. Haptic devices using pneumatic actuators require air tanks or air blowers that constantly blow air as well as tubes to connect them [52][53][54]. Haptic devices that use high voltages typically receive power from power suppliers or voltage generators in laboratory environments [13,16].…”

This study aims to explore a feasible form of a haptic device for common users. We propose HAPmini, a novel graspable haptic device that enhances the user’s touch interaction. To achieve this enhancement, the HAPmini is designed with low mechanical complexity, few actuators, and a simple structure, while still providing force and tactile feedback to users. Despite having a single solenoid-magnet actuator and a simple structure, the HAPmini can provide haptic feedback corresponding to a user’s 2-dimensional touch interaction. Based on the force and tactile feedback, the hardware magnetic snap function and virtual texture were developed. The hardware magnetic snap function helped users perform pointing tasks by applying an external force to their fingers to enhance their touch interaction performance. The virtual texture simulated the surface texture of a specific material through vibration and delivered a haptic sensation to users. In this study, five virtual textures (i.e., reproductions of the textures of paper, jean, wood, sandpaper, and cardboard) were designed for HAPmini. Both HAPmini functions were tested in three experiments. First, a comparative experiment was conducted, and it was confirmed that the hardware magnetic snap function could increase the performance of pointing tasks to the same extent as the software magnetic snap function could, which is commonly used in graphical tools. Second, ABX and matching tests were conducted to determine whether HAPmini could generate the five virtual textures, which were designed differently and sufficiently well for the participants to be distinguished from each other. The correctness rates of the ABX and the matching tests were 97.3% and 93.3%, respectively. The results confirmed that the participants could distinguish the virtual textures generated using HAPmini. The experiments indicate that HAPmini enhances the usability of touch interaction (hardware magnetic snap function) and also provides additional texture information that was previously unavailable on the touchscreen (virtual texture).

“…Very differently from these approaches, Grabity [5] achieves illusion of weight using asymmetric skin deformation, while Rietzler et al [25] achieved it without applying any physical force or tactile feedback, but instead by using a software approach that deliberately creates perceivable tracking offsets that nudge users to lift their arm higher. Finally, researchers also explored several methods to generate impact forces: ElastImpact [38] and ElasticVR [40] stretch elastic bands and releases them to cause instant impacts on the arm and on a Head-Mounted Display (HMD), while Wind-blaster [17] uses the thrust of two propellers, mounted on each side of the wrist, to render impacts such as the recoil of a gun.…”

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.
