METHOD OF UNLOCKING AN ELECTRONIC DEVICE BASED ON MOTION RECOGNITIONS, MOTION RECOGNITION UNLOCKING SYSTEM, AND ELECTRONIC DEVICE INCLUDING THE SAME

摘要

A method of unlocking an electronic device based on motion recognitions generates motion information by detecting a user's motion, calculates optical flows based on the motion information, converts the optical flows into a code by sorting and grouping the optical flows based on predetermined reference directions, generates a comparison result indicating whether the code is consistent with a predetermined password by comparing the code with the predetermined password, and determines whether to unlock the electronic device based on the comparison result.
