Query: A Novel Contactless Human Machine Interface based on Machine Learning   This paper describes a global framework that enables contactless human
machine interaction using computer vision and machine learning techniques. The
main originality of our framework is that only a very simple image acquisition
device, as a computer camera, is sufficient to establish a rich human machine
interaction as traditional devices such as mouse or keyboard. This framework is
based on well known computer vision techniques and efficient machine learning
techniques are used to detect and track user hand gestures so the end user can
control his computer using virtual interfaces with very simple gestures.
