“…A haptic device called "the digital clay" tracks the movement of the hand and prepositions various stimuli in space to provide it to the user [21]. In addition, methods of providing feedback about many properties using soft robotics such as particle jamming [22] or electrostatic effect [23] or methods of making multimodal haptic devices using sensors and actuators made of new materials such as shape memory polymer [24].…”

The quality of surgical operation is very important for the patients’ safety and the reduction of aftereffects after surgery. To do this, practicing surgical operations is also increasingly important. Due to the development of hardware and simulation techniques such as virtual reality (VR), VR simulators have been developed as a method to train surgeons and medical students majoring in surgery. In addition, controllers that support various kinds of haptic feedback have also been developed for a more realistic and immersive user experience. In this study, we introduce a morphable haptic controller that provides geometric and tactile feedback to users and propose a VR simulation system using this controller. This system is designed to perform a high tibial osteotomy in a virtual environment. The morphable haptic controller attached to the system through the input mapping daemon provides the senses of multiple surgical instruments used in the simulation. As a result, the haptic controller achieves an outstanding result through an actual interaction between surgical tools and the surgical sites. We verified that this was effective in surgery training through orthopedic surgeons.

“…One promising topic is to explore soft haptics, which utilizes the latest technologies in soft robotics based on novel flexible and extensible materials. Some promising solutions have been explored, for example, to produce a device that can change its shape and softness using particle jamming [82] , change its surface roughness using electrostatic effect [83] , change its softness using tension control of a thin film [84] , change its virtual tissue stiffness [85] and virtual volumetric shapes [86] using magnetic repulsion technology.…”

Immersion, interaction, and imagination are three features of virtual reality (VR). Existing VR systems possess fairly realistic visual and auditory feedbacks, and however, are poor with haptic feedback, by means of which human can perceive the physical world via abundant haptic properties. Haptic display is an interface aiming to enable bilateral signal communications between human and computer, and thus to greatly enhance the immersion and interaction of VR systems. This paper surveys the paradigm shift of haptic display occurred in the past 30 years, which is classified into three stages, including desktop haptics, surface haptics, and wearable haptics. The driving forces, key technologies and typical applications in each stage are critically reviewed. Toward the future high-fidelity VR interaction, research challenges are highlighted concerning handheld haptic device, multimodal haptic device, and high fidelity haptic rendering. In the end, the importance of understanding human haptic perception for designing effective haptic devices is addressed. IntroductionIn 1965, Ivan Sutherland proposed the concept "the ultimate display", which represents the birth of virtual reality (VR) [1] . In his seminal work, he introduced three features of VR: immersion, interaction, and imagination. In past 50 years, thanks to the research in computer graphics and sound synthesis, existing VR systems possess fairly realistic visual and auditory feedback. However, haptic feedback is far from user's perceptual expectations. The experiences of haptic sensation in most VR systems are rather poor compared to the abundant haptic properties that human can perceive in the physical world.Haptic feedback is indispensable for enhancing immersion, interaction, and imagination of VR systems.Interaction can be enhanced by haptic feedback as users can directly manipulate virtual objects, and obtain ·Review· Dangxiao WANG et al: Haptic display for virtual reality: progress and challenges immediate haptic feedback. Immersion of the VR system can be enhanced in terms of providing more realistic sensation to mimic the physical interaction process. Imagination of users can be inspired when haptics can provide more cues for user to mentally construct an imagined virtual world beyond spatial and/ or temporal limitations.The haptic sensation obtained through virtual interaction is severely poor compared to the sensation obtained through physical interaction. In our physical life, the haptic channel is pervasively used, such as perception of stiffness, roughness and temperature of the objects in external world, or manipulation of these objects and motion or force control tasks such as grasping, touching or walking etc. In contrary, in virtual world, haptic experiences are fairly poor in both quantity and quality. Most commercial VR games and movies only provide visual and auditory feedbacks, and a few of them provide simple haptic feedback such as vibrations. With the booming of VR in many areas such as medical simulation and product design, there is a...
