The Snail: A Wearable Actuated Prop to Simulate Grasp of Rigid and Soft Objects in Virtual Reality.
The Snail is a wearable haptic interface that enables users to experience force feedback when grasping objects in Virtual Reality. It consists of a 3D-printed prop attached to the tip of the thumb that can rotate thanks to a small actuator. The prop is shaped like a snail to display different grasping sizes, ranging from to , according to its orientation. The prop displays the force feedback, so forces over can be displayed between fingers using small and low-power actuation. Very rigid objects can be rendered when the prop remains static, but rotations when the users grasp the prop also allow for the simulation of soft objects. The Snail is portable, low-cost, and easy to reproduce because it is made of 3D-printed parts. The design and performance of the device were evaluated through technical evaluations and 3 user experiments. They show that participants can discriminate different grasping sizes and levels of softness with the interface. The Snail also enhances user experience and performances in Virtual Reality compared to standard vibration feedback.
期刊介绍：
IEEE Transactions on Haptics (ToH) is a scholarly archival journal that addresses the science, technology, and applications associated with information acquisition and object manipulation through touch. Haptic interactions relevant to this journal include all aspects of manual exploration and manipulation of objects by humans, machines and interactions between the two, performed in real, virtual, teleoperated or networked environments. Research areas of relevance to this publication include, but are not limited to, the following topics: Human haptic and multi-sensory perception and action, Aspects of motor control that explicitly pertain to human haptics, Haptic interactions via passive or active tools and machines, Devices that sense, enable, or create haptic interactions locally or at a distance, Haptic rendering and its association with graphic and auditory rendering in virtual reality, Algorithms, controls, and dynamics of haptic devices, users, and interactions between the two, Human-machine performance and safety with haptic feedback, Haptics in the context of human-computer interactions, Systems and networks using haptic devices and interactions, including multi-modal feedback, Application of the above, for example in areas such as education, rehabilitation, medicine, computer-aided design, skills training, computer games, driver controls, simulation, and visualization.
