Congruent Visuo-Tactile Feedback Facilitates the Extension of Peripersonal Space

Hannes Bleuler, Olaf Blanke, Ali Sengül, Michiel van Elk

Effective tool use relies on the integration of multisensory signals related to one's body and the tool. It has been shown that active tool use results in an extension of peripersonal space, i. e., the space directly surrounding the human body. In the pres ...

Visuo-tactile integration and body ownership during self-generated action

Hannes Bleuler, Olaf Blanke, Jane Aspell, Giulio Rognini, Ali Sengül, Roy Salomon

Although there is increasing knowledge about how visual and tactile cues from the hands are integrated, little is known about how self-generated hand movements affect such multisensory integration. Visuo-tactile integration often occurs under highly dynami ...

Force feedback facilitates multisensory integration during robotic tool use

Hannes Bleuler, Olaf Blanke, Jane Aspell, Giulio Rognini, Ali Sengül, Michiel van Elk

The present study investigated the effects of force feedback in relation to tool use on the multisensory integration of visuo-tactile information. Participants learned to control a robotic tool through a surgical robotic interface. Following tool-use train ...

Extending the body to virtual tools using a robotic surgical interface: evidence from the crossmodal congruency task

Hannes Bleuler, Olaf Blanke, Jane Aspell, Giulio Rognini, Ali Sengül, Michiel van Elk

The effects of real-world tool use on body or space representations are relatively well established in cognitive neuroscience. Several studies have shown, for example, that active tool use results in a facilitated integration of multisensory information in ...

Tendon-Based Transmission for Surgical Robotics: Systematic Experimental Friction Modeling

Hannes Bleuler, Patrick Schoeneich, Ricardo Daniel Rita Beira, Masayuki Hara, Ali Sengül

Increased miniaturization of surgical instruments is essential to successfully perform surgical procedures in restricted areas as in many applications of minimally-invasive surgery. Miniaturization permits increase in dexterity and decrease in access incis ...

Modeling and Design of a Gripper for a Robotic Surgical System Integrating Force Sensing Capabilities in 4 DOF

Hannes Bleuler, Mathieu Joseph Charles Stephan, Ricardo Daniel Rita Beira, Laura Santos Carreras, Giulio Rognini, Ali Sengül

This paper reports the design of a Minimally Invasive Surgery (MIS) gripper with four degrees of freedom force sensing capabilities. It will be used to provide force feedback during surgical interventions in which the surgeon will remotely manipulate surgi ...

Influence of force and torque feedback on operator performance in a VR-based suturing task

Hannes Bleuler, Roger Gassert, Ricardo Daniel Rita Beira, Laura Santos Carreras, Ali Sengül

The introduction of Minimally Invasive Surgery (MIS) has revolutionised surgical care, considerably improving the quality of many surgical procedures. Technological advances, particularly in robotic surgery systems, have reduced the complexity of such an a ...
