The today mainly incorporated sensory modalities vision and hearing are most often highly charged due to an increasing number, as well as a rising complexity of diversified assistance systems in vehicles. These systems, originally developed for "supporting" the driver in its tasks, increasingly directs to operation errors caused by cognitive overload. The sense of touch - as additional interaction...
Networked haptic cooperation entails direct interaction among users as well as joint manipulation of virtual objects. To increase the realism of both types of interactions, this paper introduces remote dynamic proxies. Remote dynamic proxies are second order dynamic representations of users at the remote peer sites. They are generated according to dynamics laws and are controlled by the user whom...
Using haptic (the sensing of touch) technology as an interface in medical and surgical procedures is a large interesting goal because of the benefits involved. This work presents a developed tool for evaluating the performance of a classic 2D-3D processing of a stack of medical preoperative images, and a new version of an efficient and simple algorithm for the integration of the haptic sense in a...
Interventional radiology is a rapidly expanding speciality using minimally invasive techniques to treat a multitude of clinical problems. Current work in progress aims to create an affordable virtual training tool to reduce training times and patient risk during a trainee practitioners learning cycle. The procedure of arterial catheterisation has been broken down into a number of subtasks, one of...
We are interested in whether humans create a model of their partner when they jointly manipulate an object in a virtual task without haptic feedback. In such a scenario the partner is perceived as a disturbance because she/he is responsible for inconsistencies between the visual and proprioceptive feedback of the individual. To gain basic knowledge on the predictability of such disturbances we compare...
A control methodology for the operation of a hydraulic excavator using a haptic operating device is developed. The main idea is to use position controllers for both the excavator and the operating device where both control loops output the reference position to the other, i.e., two position controlled systems are placed in a feedback loop with each other. The human operator acts as an input disturbance...
Performance improvements in graphics hardware have made it possible to visualize complex virtual environments and provided opportunities to interact with these in a more realistic way. In this paper a virtual reality application for simulating a billiards game is presented. A real billiard cue is used and its movements are reproduced in the virtual environment using a visual marker detection system...
A novel haptic teleoperated scheme for an efficient obstacle avoidance under human guidance is introduced. A remote robot immersed in an environment with obstacles is guided by a user using the end-effector of a haptic device. The system provides force feedback to the user when he approaches a potential field surrounding an obstacle. The user assigns the potential fields to the obstacles based on...
The model human cochlea (MHC) is a sensory substitution technique for presenting music as multiple discrete channels of vibrotactile stimuli. The MHC prototype was introduced to a group of deaf senior citizens at a community centre, where they could try the chair, and provide us with feedback about their experience. Preliminary results from this work suggest that the MHC can potentially offer a more...
