Virtual reality: Technologies, medical applications and challenges

One of the most amazing capacities of the human mind is its ability to go beyond its boundaries. The well-known example of the "blind man" by Gregory Bateson helps us understand how our mind is able to expand its potentiality thanks to the use of a tool. This famous example demonstrates two specific features that characterize the relationship between the human mind and the use of tool. From a neuropsychological point of view, the tool is integrated in near space, extending it to the end point of the instrument. From a phenomenological point of view, we are present in the tool because we can use it in an intuitive way to realize our intentions.
