Abstract

A switching method for an electronic device having sensing regions is mentioned. The switching method is configured to detect signals received by the electronic device, so as to switch the states of the electronic device. The switching method comprises receiving a first signal at a first moment and receiving a second signal at a second moment, wherein the first signal is generated by touching a first sensing region and the second signal is generated by touching a second sensing region; measuring a triggering duration and determining whether the triggering duration is consistent with a predetermined duration, when the first signal and the second signal are inputted simultaneously; switching the electronic device from a first state to a second state, if the triggering duration is consistent with the predetermined duration; and maintaining the electronic device in the first state, if the triggering duration is not consistent with the predetermined duration.

Claims

1. A switching method for an electronic device having a plurality of sensing regions, the switching method being configured to switch states of the electronic device and comprising:

(a) generating a first signal by touching a first sensing region, when the electronic device is in a first state;

(b) displaying at least one indication for a predetermined gesture on a display unit of the electronic device;

(c) generating a second signal by touching a second sensing region, wherein the first sensing region and the second sensing region are disposed on at least one of the sides of the electronic device except the side that a display unit of the electronic device is configured on, the at least one indication changes with the second signal;

(d) determining whether a touching manner and a moving path of the second signal are consistent with the predetermined gesture when receiving the second signal during a period in which the first signal has been received;

(e) switching the electronic device from the first state to a second state when the second signal is consistent with the predetermined gesture and when the first signal has been received; and

(f) maintaining the electronic device in the first state when the second signal is not consistent with the predetermined gesture or when the first signal has not been received;

wherein the first state is a locked state or a sleep state, and the second state is an unlocked state, the touch display panel of the electronic device is locked in the locked state or the sleep state, the touch display panel of the electronic device is unlocked in the unlocked state.

2. The switching method according to claim 1, wherein the at least one indication is a movie, a graphic an animation or a sound.

3. The switching method according to claim 1, further comprising:

re-executing the steps (a) to (d), when the electronic device being in the first state and the second signal being not consistent with the predetermined gesture.

4. An electronic device, comprising:

a first sensing region configured to generate a first signal when the first sensing region is touched;

a second sensing region configured to generate a second signal when the second sensing region is touched;

at least one processing unit electrically connected to the first sensing region and the second sensing region, the processing unit being configured to determine whether to switch the electronic device from a first state to a second state according to the first signal and the second signal; and

a display unit configured to display at least one indication for a predetermined gesture;

when the processing unit is in the first state, the processing unit being configured to receive the first signal generated from the first region, being configured to receive the second signal generated from the second region after the display unit displays the at least one indication and being configured to determine whether a touching manner and a moving path of the second signal are consistent with the predetermined gesture when the second signal is received during a period in which the first signal has been received, and when the second signal is consistent with the predetermined gesture and the electronic device being switched from the first state to the second state when the first signal has been received;

wherein the first sensing region and the second sensing region are disposed on at least one of the sides of the electronic device except the side that a display unit of the electronic device is configured on, the at least one indication changes with the second signal;

wherein the first state is a locked state or a sleep state, and the second state is an unlocked state, the touch display panel of the electronic device is locked in the locked state or the sleep state, the touch display panel of the electronic device is unlocked in the unlocked state.

5. The electronic device according to claim 4, wherein the at least one indication is a movie, a graphic or an animation.

6. The electronic device according to claim 4, wherein when the electronic device is in the first state and the second signal is not consistent with the predetermined-gesture, the electronic device is configured to detect the second signal in the first state.
