Multimodal interfaces have been shown to increase user performance for a variety of tasks. We have been investigating the synergistic benefits of haptic scientific visualization using an integrated, semi-immersive virtual environment. The Visual Haptic Workbench provides multimodal interaction; immersion is enhanced by head and hand tracking, haptic feedback, and additional audio cues. We prese...

Haptic feedback is currently emerging as a feasible solution to cope with the security-related issues of automobile touch-screen displays, and at the same time to improve users satisfaction and quality of use. Therefore, we have developed a fuzzy symbolic model of haptic perception for automobile interfaces in cooperation with an automotive ergonomics expert. The model predicts the induced comf...

Torque models are presented for five mechanical knobs that were characterized using the rotary haptic camera shown Figure 1. Non-linear least squares fitting was used to estimate model parameters for position, velocity, and acceleration model parts. Additionally, two simulated knobs were mod-eled to test the accuracy of the characterization algorithm. A haptic camera does for touch what a typic...

This paper describes a technique for the real-time modeling of deformable tissue. Specifically geared towards needle insertion simulation, the low computational requirements of the model enable highly accurate haptic feedback to a user without introducing noticeable time delay or buzzing generally associated with haptic surgery simulation. Using a spherical voxel array combined with aspects of ...

This paper describes a robotic hand, LUCS Haptic Hand I, that has been built as a first step in a project aiming at the study haptic perception. Grasping tests with the hand were done with different objects, and the signal patterns from the sensors were studied and analyzed. The results suggest that LUCS Haptic Hand I provides signal patterns that are possible to categorize. Certain higher-leve...

We demonstrate applications of a new actuator, the Haplug, in dynamic virtual environments. The haplug is a linear voice coil motor packaged between springs in a plug-like casing. Response and bandwidth of the haplug are optimized for haptic interactions, and tuned by the motor inertia and spring stiffness. A pair of haplugs is mounted on the hand-tracking controllers of HTC Vive and renders a ...

Abstract Commonly used haptic interaction techniques are typically limited to touching solid glass displays or vibrations. Although there are more complex experimental haptic interfaces, their real application is often unclear. Our prototype of tangible heat map for visually imp...

In this paper, we propose a new concept of visual/haptic interfaces called WYSIWYF display. The proposed concept provides correct visual/haptic registration using a visionbased object tracking technique and a video keying technique so that what the user can see via a visual interface is consistent with what he/she can feel through a haptic interface. Using Chroma Keying, a live video image of t...

-In haptic devices the problem of major concern is the inertia offered by the haptic device. When using it in unconstrained space, it should offer the least inertia. Depending on the interaction mechanism we are required to adapt different control algorithms to maintain transparency. This paper investigates force feedback method of inertia reduction and analyses its advantages over the feed for...

HIRO (Haptic Interface RObot) is a new device that enables users to interact and feel the virtual object safely. Hand interaction with virtual object requires a more elaborated model than the Haptic Interaction Point (HIP) due to the complex shape of the virtual hand. This paper describes a general haptic rendering of 3D object for hand interaction that takes in consideration the real shape and...
