The purpose of this study was to investigate the effectiveness of a haptic augmented simulation in learning physics. The results indicate that haptic augmented simulations, both the force and kinesthetic and the purely kinesthetic simulations, were more effective than the equivalent non-haptic simulation in providing perceptual experiences and helping elementary students create multimodal repre...

In haptic simulation, a force feedback device is combined with a digital representation of a virtual world to create a kinesthetically immersive experience. The force feedback device, or haptic display, is usually a robotic manipulator with which a human operator interacts physically, usually through a handle, stylus, finger-pad or some other form of customized interface. Modeling of the haptic...

BACKGROUND Virtual surgery may improve learning and provides an opportunity for pre-operative surgical rehearsal. We describe a novel haptic temporal bone simulator specifically developed for multicore processing and improved visual realism. A position locking algorithm for enhanced drill-bone interaction and haptic fidelity is further employed. The simulation construct is evaluated against cad...

This paper presents a physically based method to deal with haptic feedback of manipulated deformable virtual objects in contact with rigid or deformable environment. The haptic rendering algorithm is based on the Signorini’s formulation of the contact as proposed in theoretical mechanics. Since haptic interaction requires high refresh rates, a multi-threaded methodology, sharing configuration v...

Using a force feedback device within the framework of deformable object simulation remains difficult because of the incompatibility between the computation time needed by realistic deformable models and high refresh frequencies necessary for real-time haptic rendering. Giving the user a good haptic sensation requires refreshing the applied forces at least ten times more often than for giving a ...

The reproduced tactile sensation of haptic interfaces usually selectively reproduces a certain object attribute, such as the object's material reflected by vibration and its surface shape by a pneumatic nozzle array. Tactile biomechanics investigates the relation between responses to an external load stimulus and tactile perception and guides the design of haptic interface devices via a tactile...

This is a survey of research issues for haptic and locomotion interfaces. A key issue is the workspace and dexterity of haptic devices. In the simulation of real environments, interactive geometric computations on complex models are a fundamental problem. Haptic rendering of forces of contact are increasingly based on measurements on real environments. Scientific visualization is another promis...

Common approaches for the haptic rendering of complex scenarios employ multi-rate simulation schemes. Here, the collision queries or the simulation of a complex deformable object are often performed asynchronously on a lower frequency, while some kind of intermediate contact representation is used to simulate interactions on the haptic rate. However, this can produce artifacts in the haptic ren...
