  In this paper we present an original contactless human machine interface for
driving car. The proposed framework is based on the image sent by a simple
camera device, which is then processed by various computer vision algorithms.
These algorithms allow the isolation of the user's hand on the camera frame and
translate its movements into orders sent to the computer in a real time
process. The optimization of the implemented algorithms on graphics processing
unit leads to real time interaction between the user, the computer and the
machine. The user can easily modify or create the interfaces displayed by the
proposed framework to fit his personnel needs. A contactless driving car
interface is here produced to illustrate the principle of our framework.
