Obtaining and interacting with information has always been at the centre of humanity. We have always sought to innovate and improve these interactions by creating linking devices such as switches or remote controls. In seeking a more natural interaction with machines, we have expanded to the creation of devices, such as the mouse which allowed us to reproduce the movements that the user makes, on a screen. Then, followed a new way of expressing ourselves on a machine through tactile terminals,which is ubiquitous these days on smartphones or digital tablets. Extensive research has also been undertaken on various projects that capture other senses than the “touch”. Hence, technologies such as the Kinectallow users to interact with digital information using just movement. But the most original invention will surely be the total control of holographic projections – perhaps the future of interactions between man and machine.
