Abstract
A device unlocking method. The method shows challenging icons in challenging rounds and traces user pupils. The method requires a right user to have his pupil movement conform to a challenging icon through the challenging rounds. A device unlocks when a combined moving vector representing the pupil movement passes the challenging rounds and matches an unlocking condition.
Claims20
A device unlocking method based on eye recognition executable by an electronic device, comprising:
- identifying a first character point of a pupil image utilizing a first pupil identifying scheme, and a second character point of the pupil image utilizing a second pupil identifying scheme;
- tracking a first moving vector of the first character point and a second moving vector of the second character point;
- obtaining a combined moving vector from the first moving vector weighted with a first weight and the second moving vector weighted with a second weight;
- determining whether the combined moving vector matches an unlock condition, the unlock condition being predefined;
- and
- performing device unlocking when the combined moving vector matches the unlock condition.
