Towards multimodal Haptics for teleoperation: Design of a Tactile Thermal Display

Hannes Bleuler, Laura Santos Carreras, Giulio Rognini

Surgical robotics is among the most challenging applications of motion control. Present and future systems are essentially master-slave systems. Our work focuses on force-feedback and haptic interfaces. In this context, we study multimodal haptic interface ...

Tactile Feedback Improves Performance in a Palpation Task: Results in a VR-Based Testbed

Hannes Bleuler, Roger Gassert, Kaspar Leuenberger, Evren Samur, Laura Santos Carreras

Robotic surgery provides many benefits such as reduced invasiveness and increased dexterity. This comes at the cost of no direct contact between surgeon and patient This physical separation prevents surgeons from performing direct haptic exploration of tis ...

Design and Psychophysical Evaluation of a Tactile Pulse Display for Teleoperated Artery Palpation

Hannes Bleuler, Roger Gassert, Philippe Rétornaz, Kaspar Leuenberger, Laura Santos Carreras

During traditional open procedures, surgeons directly palpate tissues before dissecting them. In this way, they can avoid the accidental damage of hidden arteries that can lead to fatal hemorrhage. New Minimally Invasive Surgical (MIS) techniques progressi ...
