The current state of current displays and interactive tools is limited. Indeed a mouse and a keyboard provide limited efficiency when it comes to manipulating 3D objects. Monitors are flat 2D screens with a limited FOV. Joystics and mises have few degrees of freedom, a joystic has in average 3 to 4 degrees of freedom as opposed to our had which has 27 degrees of freedom and is more natural to use to manipulate objects, therefore more intuitiveness would be added by use of our hands. That is why Gloves and styluses as the phantom which provide a higher degree of freedom has been used, but these have the disadvantage of having a physical connection. Trackers as the polymous also have been used, but these are electromagnetic tracker that needs a combersum physical connection. Likewise for head mounted displays who provide a better ...

We need to create a system, that has the advantages of a wide field of view, high degree of freedom, stereoscopic, and yet be intuitive and not requiring any combersom physical connections...
