TL;DR: This paper presents a novel haptic device providing both kinesthetic and cutaneous cues informative of shape geometry at the contact point and shows how this local augmentation of displayed haptic information can improve human performance in shape exploration, by assessing perception thresholds in curvature discrimination.
Abstract: This paper presents a novel haptic device providing both kinesthetic and cutaneous cues informative of shape geometry at the contact point. The system is composed of a supporting kinesthetic haptic interface and an innovative fingertip haptic display that can instantaneously orient a small plate along the tangent plane at the contact point with a virtual shape and bring it in contact with the fingertip. We show how this local augmentation of displayed haptic information can improve human performance in shape exploration, by assessing perception thresholds in curvature discrimination. When kinesthetic feedback was enriched with cutaneous cues, we found a significantly lower threshold for curvature discrimination (1.51 ± 0.2 m-1 vs. 2.62 ± 0.61 m-1, p <.05) for stimuli constituted of spheres with curvature ranging in the interval from 4--6 m-1. This confirms the importance in haptic perception of the stimulation of cutaneous mechanoreceptors at the fingertip.

07 Sep 2010TL;DR: A novel approach to pedestrian navigation using bearing-based haptic feedback, where people are guided in the general direction of their destination via vibration, but additional exploratory navigation is stimulated by varying feedback based on the potential for taking alternative routes.
Abstract: In this article we describe a novel approach to pedestrian navigation using bearing-based haptic feedback. People are guided in the general direction of their destination via vibration, but additional exploratory navigation is stimulated by varying feedback based on the potential for taking alternative routes. We describe two mobile prototypes that were created to examine the possible benefits of the approach. The successful use of this exploratory navigation method is demonstrated in a realistic field trial, and we discuss the results and interesting participant behaviours that were recorded.

02 Dec 2010TL;DR: In this article, a system with a touchscreen generates haptic effects in response to a manipulation of text displayed on the touchscreen, and then generates a type of haptic event that is based at least in part on the type of the manipulation that was determined.
Abstract: A system with a touchscreen generates haptic effects in response to a manipulation of text displayed on the touchscreen. The system senses a touch within the text, and determines if the touch is a manipulation of the text, and determines the type of the manipulation. The system then generates a type of haptic event that is based at least in part on the type of the manipulation that was determined.

TL;DR: Experimental results illustrated that the designed haptic catheter operation system can be used for teleoperation and for training the surgeon for the non-experience.
Abstract: Minimally invasive surgery and therapy is popularly used both for diagnosis and for surgery. Teleoperation, a promising surgery, is used to protect the surgeon from X-ray radiation as well as to address the problem of lacking experienced surgeons in remote rural areas. However, surgery success ratio should be considered because the surgeon was separated from the patient remotely. A most effective addressing method to improve success ratio is design of a haptic interface as a master console, which can provide the “immersive” operation to the surgeon. In this study, a haptic catheter operation system for teleoperation through exploiting magnetorheological fluids is proposed to solve the safety problem. The haptic sensation is provided by varying the viscosity of the magnetorheological fluids by adjusting the magnetic field, which is dependent on the force measured in the slave manipulator. Therefore, three parts of the haptic interface were designed and fabricated: magnetic field, magnetorheological fluids ...

TL;DR: A new method for real‐time rigid body simulations for haptic interactions based on a penalty method regarding contact volume is proposed, which prohibits direct connection of haptic interfaces.
Abstract: This paper proposes a new method for real-time rigid body simulations for haptic interactions based on a penalty method regarding contact volume. Analytical methods for calculation of contact forces require too much time to maintain fast update rates for haptic controls. In addition, they prohibit direct connection of haptic interfaces. Penalty methods, which employ spring-damper models for calculation of contact forces, offer a very rapid rate of iterations. In addition, they permit direct connection of haptic interfaces. Penalty methods are good for haptic interactions. However, previous penalty methods do not regard distribution of contact forces over the contact area. For that reason, they can’t calculate normal and friction forces on face-face contacts correctly. We propose a distributed spring-damper model on a contact area to solve these problems. We analyze threedimensional geometries of the intersecting portion on the polyhedral objects. Then, we integrate forces and torques of distributed spring-damper models. We implement a proposed simulator and compare it with a point-based penalty method and constraint method. The comparison shows that the proposed simulator improves accuracy of the simulation of face-face contact and friction forces and the simulation speed. In addition, we attach a six degree-of-freedom (6-DOF) haptic interface to the simulator. Users can feel 6-DOF force feedback and input 6-DOF motions.
