How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Article
Surface exploration in virtual reality has a large potential to enrich the user's experience. It could for example be used to train and simulate medical palpation. During palpation users tap, indent, rub in-contact and retract at the surface of a sample to estimate its underlying properties. However, up to now there is no good approach to render su...

Robotic minimal invasive surgery is gaining acceptance in surgical care. In contrast with the appreciated 3D vision and enhanced dexterity, haptic feedback is not offered. For this reason robotics is not considered beneficial for delicate interventions such the endometriosis. Overall, haptic feedback remains debatable and yet unproven except for so...
Article
Advances in miniaturized surgical instrumentation are key to less demanding and safer medical interventions. In cardiovascular procedures interventionalists turn towards catheter-based interventions, treating patients considered unfit for more invasive approaches. A positive outcome is not guaranteed. The risk for calcium dislodgement, tissue damag...

Lasers are being used in various surgical procedures to remove tissue or bones, to coagulate vessels or other structures. Due to difficulties in handling only a limited number of surgeons manage to display sufficient levels of precision in Minimally Invasive Surgery (MIS) procedures. Prior works on robotic laser surgery demonstrated shorter learnin...
Conference Paper
Virtual Reality technology takes in an increasingly prominent role in modern medical training programs. The fidelity of the Virtual Reality environment is of crucial importance and directly relates to the quality of skill transfer. To train interventions that rely on physical interaction with the patient, high-quality haptic feedback should be prov...
Conference Paper
Since years the elevator sector is being undertaken the downsizing components (motors, sheaves...) to gain space in the systems. Due to the reduction of sheaves diameter, metallic ropes with polymeric coatings are being employed to get a significant degree of adherence between rope and sheave. There are critical gaps in knowledge about the contact...
