Three-dimensional object identifying system
First Claim
1. A three-dimensional object identifying system comprising:
- a surface;
a signal generating part that generates a modulation signal;
a light emitting part that emits light based on said modulation signal to a three-dimensional object, the light emitting part being integral to the surface;
a light receiving part that receives reflected light from said three-dimensional object and produces a detection signal, the light receiving part being integral to the surface;
a detecting part that detects correlation information on the correlation between said detection signal and said modulation signal; and
an identifying part that performs identifying processing for said three-dimensional object on the basis of both precataloged correlation information and said detected correlation information.

Abstract
A three-dimensional object identifying system is disclosed which identifies a three-dimensional shape object optically such as a part of a human body for preventing an information apparatus such as a personal computer from being used by any other illegitimate user than a legitimate user. The three-dimensional object identifying system has a function generating unit which generates modulation signals, light emitting elements which emit lights based on the modulation signals to a three-dimensional object, light receiving elements which receive reflected lights from the three-dimensional object and which produce detection signals, a correlation detecting unit which detects correlation information between each detection signal and modulation signal, and an identifying unit which performs identifying processing for the three-dimensional object on the basis of both pre-cataloged correlation information and the detected correlation information.

27. An information apparatus comprising:
-
a general-purpose input device that inputs information corresponding to an input operation performed by an input operator;
a processing unit that processes the information inputted from said general-purpose input part;
a light emitting part that emits light to said input operator and that is integral to said input device;
a light receiving part that receives reflected light from said input operator and that is integral to said input device; and
an identifying part that acquires from said light receiving part light intensity information corresponding to the posture of at least a part of the body of said input operator when the input operator uses said general-purpose input device, and then performs identifying processing of the input operator on the basis of said light intensity information and cataloged information. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)
