“…Typically, passive haptic props are mapped one-to-one to their virtual counterparts. Recent work has warped virtual space to map many virtual objects onto a single physical object [2, 15], introducing a discrepancy between the seen and felt hands: the virtual hand’s motion (in warped space) matches what is seen, and the real hand’s motion matches what is felt (Figure 1, upper left and right). Vision usually dominates proprioception when the two conflict; people tend to believe their hand is where they see it, rather than where they feel it [4, 9, 21, 22].…”

Redirected Touching is a technique in which virtual space is warped to map many virtual objects onto one real object that serves as a passive haptic prop. Recent work suggests that this mapping can often be predictably unnoticeable and have little effect on task performance. We investigated training and adaptation on a rapid aiming task in a real environment, an unwarped virtual environment, and a warped virtual environment. Participants who experienced a warped virtual space reported an initial strange sensation, but adapted to the warped space after short repeated exposure. Our data indicate that all the virtual training was less effective than real-world training, but after adaptation, participants trained as well in a warped virtual space as in an unwarped one.

Interaction in VR involves large body movements, easily inducing fatigue and discomfort. We propose Erg-O, a manipulation technique that leverages visual dominance to maintain the visual location of the elements in VR, while making them accessible from more comfortable locations. Our solution works in an open-ended fashion (no prior knowledge of the object the user wants to touch), can be used with multiple objects, and still allows interaction with any other point within user's reach. We use optimization approaches to compute the best physical location to interact with each visual element, and space partitioning techniques to distort the visual and physical spaces based on those mappings and allow multi-object retargeting. In this paper we describe the Erg-O technique, propose two retargeting strategies and report the results from a user study on 3D selection under different conditions, elaborating on their potential and application to specific usage scenarios.

“…For example, Kohli (2010) presented redirected touching; a spatial warping that leverages discrepancies between the haptic feedback of the real world and the visual feedback of the virtual world in order to distort shape perception. Similarly, Ban, Kajinami, Narumi, Tanikawa, and Hirose (2012) simulated different shapes by slightly altering the virtual representation of a real prop as well as the position of the user's finger while he follows its outline.…”

International audienceHaptic feedback is known to improve 3D interaction in virtual environments but current haptic interfaces remain complex and tailored to desktop interaction. In this paper, we describe an alternative approach called “Elastic-Arm” for incorporating haptic feedback in immersive virtualenvironments in a simple and cost-effective way. The Elastic-Arm is based on a body-mounted elastic armature that links the users hand to his body and generates a progressive egocentric force when extending the arm. A variety of designs can be proposed with multiple links attached tovarious locations on the body in order to simulate different haptic properties and sensations such as different levels of stiffness, weight lifting, bimanual interaction, etc. Our passive haptic approach can be combined with various 3D interaction techniques and we illustrate the possibilities offered by the Elastic-Arm through several use cases based on well-known techniques such as the Bubble technique, redirected touching, and pseudo-haptics. A user study was conducted which showed the effectiveness of our pseudo-haptic technique as well as the general appreciation of the Elastic-Arm. We believe that the Elastic-Arm could be used in various VR applications which call for mobile haptic feedback or human-scale haptic sensations
