ELECTRONIC DEVICE, SECURITY WARNING SYSTEM AND METHOD

摘要

A security warning system applied in an electronic device includes a motion identifying unit, a walking speed calculation unit, an image processing unit, and an executing unit. The motion identifying unit identifies whether a number of continuous walking steps of a user of the electronic device is greater than a first predetermined value. The walking speed calculation unit calculates a walking speed of the user and compares the calculated walking speed to a second predetermined value. The image processing unit determines whether the user is in a special sidewalk. The executing unit determines whether the user is in a walking state and whether the electronic device needs to execute a security mode. An electronic device and a security warning method are also provided.

1. A security warning system applied in an electronic device, the security warning system comprising:
a motion identifying unit configured to identify whether a number of continuous walking steps of a user of the electronic device is greater than a first predetermined value; a walking speed calculation unit configured to calculate a walking speed of the user and compare the calculated walking speed to a second predetermined value; an image processing unit configured to determine whether the user is in a special sidewalk; and an executing unit configured to determine whether the user is in a walking state and whether the electronic device needs to execute a security mode; wherein if the number of continuous walking steps of the user is greater than the first predetermined value and the walking speed is smaller than the second predetermined value, the executing unit determines that the user is in the walking state; and wherein when the user is in the walking state but not in the special sidewalk, the executing unit controls the electronic device to execute the security mode.
