A new human machine interface in neurosurgery: The Leap Motion (R). 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. The recent appearance of devices such as the Leap Motion (R) (Leap Motion society, San Francisco, USA) a sensor which enables to interact with the computer without any physical contact is of major interest in the field of surgery. However, its configuration and ergonomics produce key challenges in order to adapt to the practitioner's requirements, the imaging software as well as the surgical environment. This article aims to suggest an easy configuration of the Leap Motion (R) in neurosurgery on a PC for an optimized utilization with Carestream (R) Vue PACS v11.3.4 (Carestream Health, Inc., Rochester, USA) using a plug-in (to download at: https://drive.google.com/?usp=chrome_app\#folders/0B_F4eBeBQc3ybElEeEh qME5DQkU) and a video tutorial (https://www.youtube.com/watch?v=yVPTgxg-SIk).
