Abstract:
The robotic hand illusion is a variant of the classical rubber hand illusion in which the embodiment of an artificial hand into one’s own body-representation is induced via multisensory and sensorimotor coherence. This paper elaborates on the design and implementation of a wearable robotic hand/arm-system in which sensorimotor aspects can be manipulated specifically. This wearable device opens up new possibilities for investigating complex multisensory illusions and the embodiment of robotic devices. Here, we illustrate this at the example of the so-called numbness illusion based on the results of a preliminary study. We believe that such setup might have important implications for prosthetic developments.
