We present a rigid-body simulation for multi-contact haptic interaction. The simulation is designed to make use of modern multiprocessor machines and the framework for this is discussed. An existing haptic rendering algorithm is extended to: facilitate simple implementation on a number of object types, enable the use of arbitrary objects as haptic cursors and allow multiple object contacts on t...

As the field of the computer simulation technique has advanced, the computer simulation extends its domain, enlarges its scale, and improves its quality. Nowadays the haptic sense is as important as visual one to recognize a virtual object. While the mechanisms of two senses are highly different, only one model simulates for the visual sense, processing shape deformation, and for the haptic sen...

As more and more haptic rendering algorithms are developed, the need for evaluation and comparison is becoming more pressing. However, evaluating and comparing haptic rendering algorithms presents two challenges. First, haptic systems provide bidirectional communication between humans and the computer. Therefore, the outputs of such systems are highly reliant on human inputs, which are hard to ...

The purpose of this paper is to demonstrate the simulation of the haptic interface device utilizing the admittance control method for the applications of human/virtual environment interaction. . The dynamics of the haptic interface is derived, and then it is integrated with the admittance interaction loop. In doing so, firstly, the haptic device is simulated and the design of it is done through...

in this paper a robust road departure avoidance system based on a closed-loop driver decision estimator (dde) is presented. the main idea is that of incorporating the driver intent in the control of the vehicle. the driver decision estimator computes the vehicle look ahead lateral position based on the driver input and uses this position to establish the risk of road departure. to induce a risk...

In haptic simulation, a human operator kinesthetically explores a virtual environment. To achieve a virtual sense of touch, the human interacts with an active mechanical device, called a haptic display. This paper presents an approach to guarantee that this physical manmachine interface remains stable, while maximizing performance. The key element in ensuring stability is the virtual coupling n...
