Today there is considerable interest in surgical simulators for training, operation planning, and outcome prediction. Surgical simulation often involves real-time computation of the deformations of visco-elastic human-body tissues and providing users with both graphic and haptic rendering. As humans are more sensitive to small haptic discrepancies than visual ones, good force rendering requires...

1.1 Goal We propose to investigate how to best present functions of a haptic control interface for rehabilitation and skill training applications for persons attempting to recover from traumatic brain injury (TBI) with motor control implications or seeking to train new motor skills for work and societal activities. The overarching goal of this research is to advance the state of virtual reality...

A goal of this work is proposal and construction of simulation methods of haptic reproduction and interactive visualization of a beating heart in cardiovascular surgical training and education. The data for the beating heart model was obtained from ECG-gated 3D MRI of a normal volunteer. The elastic information was assumed as a uniform value with clinically experienced elasticity. Using a real-...

This short review updates an exhaustive one written by Correa et al. in 2019 about haptic training simulation on needle insertion the medical field. Latest works refine well-known models and enhance setups methods to facilitate generically getting experimental data. We provide a complementary focus device specifications recent render this specific feedback computer-based simulators. Assessment ...

The process of styling virtual hair is a tedious task for 3D artists, who would significantly profit from more natural and intuitive ways of creating virtual hairstyles such as, for example, the possibility to simply comb virtual hair using a haptic device. However, despite significant advances in hair simulation during the last decades, physically based haptic interaction with hair is still an...

Shaping realistic hairstyles for digital characters is a difficult, long and tedious task. The lack of appropriate interaction metaphors enabling efficient and simple, yet accurate hair modeling further aggravates the situation. This paper presents 3D interaction metaphors for modeling virtual hair using haptic interfaces. We discuss user tasks, ergonomic aspects, as well as haptics-based styli...

Force and touch feedback, or haptics, can play a significant role in the realism of virtual reality surgical simulation. While it is accepted that simulators providing haptic feedback often outperform those that do not, little is known about the degree of haptic fidelity required to achieve simulation objectives. This article evaluates the effect that employing haptic rendering with different d...

Haptics have been employed in a wide set of applications ranging from teleoperation and medical simulation to arts and design, including entertainment, aircraft simulation and virtual reality. As for today, there is also a growing attention from the research community on how haptic feedback can be integrated with profit to audiovisual systems. The objective of this paper is to present the techn...

A haptic simulation environment to simulate planar threedegree-of-freedom motion has been developed by the authors. The system consists of a novel parallel manipulandum and associated control, collision detection and dynamic simulation software running on a QNX PC. This paper describes haptic interface control and outlines the control systems that have been designed for the haptic rendering of ...
