Thought consciousness and source monitoring depend on robotically-controlled sensorimotor conflicts and illusory states

Hannes Bleuler, Olaf Blanke, Pierre Progin, Masayuki Hara, Giulio Rognini, Polona Pozeg, Roy Salomon, Andrea Serino, Marco Solcà, Fosco Bernasconi, Herberto Dhanis Pedro De Barros Camacho, Giedre Stripeikyte

Thought insertion (TI) is characterized by the experience that certain thoughts, occurring in one’s mind, are not one’s own, but the thoughts of somebody else and suggestive of a psychotic disorder. We report a robotics-based method able to investigate the ...

Torso-mounted Vibrotactile Interface to Experimentally Induce Illusory Own-body Perceptions

Hannes Bleuler, Olaf Blanke, Masayuki Hara, Giulio Rognini

Recent developments in virtual reality and robotic technologies have allowed investigating the behavioural and brain mechanisms that grounds self-consciousness in the multisensory (e.g. vision and touch) and sensorimotor processing of bodily signals. Yet, ...

Four-Arm Manipulation via Feet Interfaces

Hannes Bleuler, Mohamed Bouri, Aude Billard, Walid Amanhoud, Anaïs Betsabeh Haget, Jacob Hernandez Sanchez

We seek to augment human manipulation by enabling humans to control two robotic arms in addition to their natural arms using their feet. Thereby, the hands are free to perform tasks of high dexterity, while the feet-controlled arms perform tasks requiring ...
