DEFINITION

Classification: 463/32

Three-dimensional characterization:

(under subclass 31) A visual output or display wherein the information is presented to the eye(s) in such a manner that the information is visually perceivable as an image having height, width, and depth.

(1) Note. It is not a requirement that the image actually include all three dimensions so long as the image, taken as a whole, has a general character that is perceivable as such. For example, depth perception may be simulated or perceived from a flat image by utilizing the technique of perspective or the technique of covering the image of a first object by an image of a second object that is intended to be perceived in front of the first object, etc.
