User identification system and method for identifying user
First Claim
Patent Images
1. An identification system for identifying a user by receiving a motion trajectory generated by the user, the identification system comprising:
- an image sensor for capturing a plurality of images of the motion trajectory generated by the user in a repetitive circular motion;
a storage unit for storing motion vector information of a group of users including or not including the user generating the motion trajectory, wherein each of the motion vector information includes a trajectory of said repetitive circular motion; and
a comparing unit for comparing the plurality of images with the motion vector information to identify the user according to a habitual pattern of the user of said repetitive circular motion, so that different users are differentiated according to different habitual patterns.

Abstract
The present invention discloses an identification system which includes an image sensor, a storage unit and a comparing unit. The image sensor captures a plurality of images of the motion trajectory generated by a user at different timings. The storage unit has stored motion vector information of a group of users including or not including the user generating the motion trajectory. The comparing unit compares the plurality of images with the motion vector information to identify the user. The present invention also provides an identification method.

12. An identification method, comprising:
-
receiving a plurality of images of the motion trajectories generated by a group of users including or not including the user generating the motion trajectory, wherein each motion trajectory includes a repetitive circular motion; generating the motion vector information including individual motion vector information corresponding to each user in the group of users; capturing plurality of images of a motion trajectory generated by a user; and comparing the plurality of images with pre-stored motion vector information to identify the user according to a habitual pattern of the user of said repetitive circular motion, so that different users are differentiated according to different habitual patterns. - View Dependent Claims (13, 14, 15, 16)
