Recognizing apparatus and method, recording media, and program
First Claim
1. A recognizing apparatus comprising:
- face direction sensing means for sensing a direction of a user'"'"'s face;
line-of-sight direction sensing means for sensing a direction of the user'"'"'s line of sight; and
movement recognizing means for recognizing that the user has nodded to indicate the user'"'"'s intention if the user is in a state in which the direction of the user'"'"'s face sensed by the face direction sensing means is directed downward while the direction of the user'"'"'s line of sight sensed by the line-of-sight direction sensing means is directed upward with respect to the direction of the face sensed by the face direction sensing means.

Abstract
The present invention enables a user'"'"'s movement indicating his or her intention to be recognized easily and accurately. On the basis of image data taken by a camera 13, a face direction detecting section 14 senses the direction of a user'"'"'s face and a line-of-sight sensing section 15 senses the direction of the user'"'"'s line of sight. When the user'"'"'s face is directed downward, while the user'"'"'s line of sight is directed upward with respect to the face direction, a nod recognizing section 21 recognizes that the user has nodded. When the user'"'"'s face is directed rightward or leftward, while the user'"'"'s line of sight is directed in a direction laterally opposite to the face direction, a head shake recognizing section 22 recognizes that the user has shaken his or her head. The present invention is applicable to an intention checking apparatus that checks the driver'"'"'s intention.
