TL;DR: In this paper, a tele-operated nanoscale touching system is proposed, and a continuum nan-oscale contact mechanics models are introduced, and the tele-nanorobotic system consists of a piezoresistive nanoprobe with a sharp tip as the nanorobot and force-topology sensor.
Abstract: In this paper, a teleoperated nanoscale touching system is proposed, and continuum nanoscale contact mechanics models are introduced. The tele-nanorobotic system consists of a piezoresistive nanoprobe with a sharp tip as the nanorobot and force-topology sensor, a custom-made 1-degree-of-freedom haptic device for force-feedback, three-dimensional (3D) virtual reality (VR) graphics display of the nano world for visual feedback, and a force-reflecting servo type scaled teleoperation controller. Using this system, one-dimensional and 3D touching experiments and VR simulations are realized. Scaling of nano-forces is one of the major issues of the scaled teleoperation system since nanometer scale forces are dominated by surface forces instead of inertial forces as in the macro world. As the force scaling approach, a heuristic rule is introduced where nano-forces are linearly scaled with an experimentally determined scaling parameter. Simulation results and preliminary experiments of touching silicon and InAs quantum dot nanostructures show that adhesion forces at the nanoscale can be felt repeatedly at the operator's hand, and the proposed system enables the nanoscale surface topography and contact/noncontact nano-force feedback.

TL;DR: A system that facilitates the composition and perception of intricate, musically structured spatio-temporal patterns of vibration on the surface of the body is described, and some potential evolutionary branches of tactile composition are posited.
Abstract: What if the traditional relationship between touch and music was essentially turned upside down, making the tactile sensation the aesthetic end? This paper presents a novel coupling of haptics technology and music, introducing the notion of tactile composition or aesthetic composition for the sense of touch. A system that facilitates the composition and perception of intricate, musically structured spatio-temporal patterns of vibration on the surface of the body is described. Relevant work from disciplines including sensory substitution, electronic musical instrument design, simulation design, entertainment technology, and visual music is considered. The psychophysical parameter space for our sense of touch is summarized and the building blocks of a compositional language for touch are explored. A series of concerts held for the skin and ears is described, as well as some of the lessons learned along the way. In conclusion, some potential evolutionary branches of tactile composition are posited.

TL;DR: In this article, the authors investigated the effect of haptic imaging on perceived ownership and found that people who imagine touching an object when their eyes are closed experience a level of perceived ownership similar to that of individuals who actually touch the object.
Abstract: Previous research has shown that individuals value objects more highly if they own them, a finding commonly known as the endowment effect. In fact, simply touching an object can create a perception of ownership that produces the endowment effect. Through a series of three studies, we extend this line of research in several ways. First, we investigate the effect of haptic imaging - the mental visualization of touch - on perceived ownership. We find that individuals who imagine touching an object when their eyes are closed experience a level of perceived ownership similar to that of individuals who actually touch the object. We explore the process through which this occurs, demonstrating that, when a person's eyes are closed, haptic imagery leads to perceptions of physical control, which in turn increase feelings of ownership. Moreover, the more vivid the haptic image, the greater the perception of control and the feeling of ownership. This has important implications for marketing in contexts where touch is not feasible, such as online, since haptic imagery could act as a surrogate for touch.

TL;DR: The authors describe the use of force feedback in a surgical robot system (ROBODOC), where the robot must prepare a cavity in the femur for an artificial implant, and an intuitive man-machine interface is provided.
Abstract: The authors describe the use of force feedback in a surgical robot system (ROBODOC). The application initially being addressed is total hip replacement (THR) surgery, where the robot must prepare a cavity in the femur for an artificial implant. In this system, force feedback is used to provide safety, tactile search capabilities, and an improved man-machine interface. Output of the force sensor is monitored by a safety processor, which initiates corrective action if any of several application-defined thresholds are exceeded. The robot is able to locate objects using guarded moves and force control (ball-in-cone strategy). In addition, the force control algorithm provides an intuitive man-machine interface which allows the surgeon to guide the robot by leading its tool to the desired location. An application of force control currently under development is described, where the force feedback is used to modify the cutter feed rate (force controlled velocity). >

01 Mar 2001TL;DR: A novel, interactive sculpting framework founded upon subdivision solids and physics-based modeling, equipped with natural, haptic-based interaction to provide the user with a realistic sculpting experience.
Abstract: In this paper we systematically develop a novel, interactive sculpting framework founded upon subdivision solids and physics-based modeling. In contrast with popular subdivision surfaces, subdivision solids have the unique advantage offering both the boundary representation and the interior material of a solid object. We unify the geometry of subdivision solids with the principle of physicsbased models and formulate dynamic subdivision solids. Dynamic subdivision solids respond to applied forces in a natural and predictive manner and give the user the illusion of manipulating semielastic virtual clay. We have developed a real-time sculpting system that provides the user with a wide array of intuitive sculpting toolkits. The flexibility of the subdivision solid approach allows users to easily modify the topology of sculpted objects, while the inherent physical properties are exploited to provide a natural interface for direct, force-based deformation. More importantly, our sculpting system is equipped with natural, haptic-based interaction to provide the user with a realistic sculpting experience.
