Natural and interactive 3d viewing on 2d displays

A system comprising circuitry configured to:

• determine a value for an effect implemented to display a 2D representation of a 3D scene on a 2D display device;
• determine a first user input during the display of the 2D representation of the 3D scene on the 2D display device;
• modify the value for the effect;
• change the display based on the modified value;
• determine a second user input during the changed display;
• analyze at least one of the value, the first user input, the modified value, or the second user input to determine an optimized value for the effect;
• and
• generate the changed display on the 2D display device utilizing the optimized value for the effect.

A method to display a 3D representation of a scene on a 2D display device in a manner to provide a 3D perception to a viewer, comprising:

• an active modification or a passive modification of a view projected on the 2D display device depending on a viewer preference or a viewer interaction,
• wherein the active modification or the passive modification includes introducing a movement of an object based on the 3D representation of the scene, or a change in a viewpoint based on a free viewpoint video,
• wherein the active modification is based on at least one of a gesture made by the viewer, a head movement of the viewer, or an eye movement of the viewer, and
• wherein the passive modification is based on an automatic movement of the object based on the 3D representation of the scene, or an automatic change in the viewpoint based on the free viewpoint video.
