“…However, current approaches consist of fixed arrangements of actuators forming a surface. These actuators can be embedded into the surface, such as the Nitinol actuators of Surflex [3] or the hinge elements of the Formable Crust project [22]. Other arrangements include volumetric actuators attached to a column, as proposed by Volflex [13].…”

Actuated shape output provides novel opportunities for experiencing, creating and manipulating 3D content in the physical world. While various shape displays have been proposed, a common approach utilizes an array of linear actuators to form 2.5D surfaces. Through identifying a set of common interactions for viewing and manipulating content on shape displays, we argue why input modalities beyond direct touch are required. The combination of freehand gestures and direct touch provides additional degrees of freedom and resolves input ambiguities, while keeping the locus of interaction on the shape output. To demonstrate the proposed combination of input modalities and explore applications for 2.5D shape displays, two example scenarios are implemented on a prototype system.

“…As defined by the metaphor of "the digital clay" [81,82] , the user can touch the multi-modal haptic device with bare hand, i. e., without wearing any sensors or actuators on his / her hand. The device can track the movement of the users' hand, and can produce diverse haptic stimuli in a spatial collocated and temporarily registered manner.…”

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...

This paper presents a new interaction system designed for hands-on 3D shape modeling and deformation through natural hand gestures. Our system is made of a Phantom haptic device coupled with a deformable foam ball that supports pressure sensors. These sensors detect forces exerted by the user's fingertips, and are used to control the configuration of a compliant virtual hand that is modeling soft virtual clay. During interaction, the user is provided both passive tactile feedback through the foam ball, and realistic visual feedback since the virtual hand deforms due to its interaction in the virtual environment. The combination of all these feedbacks provides the artist with a good immersion allowing for effective sculpting in a virtual world.
