Movement perception with the use of a motorized delta armrest and virtual reality

In this paper we present a combination of neuroscience experiments with the use of a parallel armrest robot to study the effects of temporal delays and spatial biases on the movement perception. A dedicated armrest to guide and manipulate the arm has been developed for these experiments. It is a three-degree-of-freedom Delta structure. In combination with a virtual reality application, the movement perception has been evaluated. The results of this study demonstrate that experimental conditions such as spatial deviations and temporal delays impair the correct self-attribution of the movements done with the motorized Delta armrest. This result shows that the motorized Delta armrest can be successfully used to study the effect of movement perception, opening up the way to new studies about the movement perception using robotic system and virtual reality.
