[A new human machine interface in neurosurgery: The Leap Motion(®). Technical note regarding a new touchless interface].

Currently, cross-sectional imaging viewing is used in routine practice whereas the surgical procedure requires physical contact with an interface (mouse or touch-sensitive screen). This type of contact results in a risk of lack of aseptic control and causes loss of time.
