Abstract

An operation method of an electronic apparatus is provided, wherein a setting procedure of safety mechanism is executed first. The procedure includes: receiving a setting operation through a setting interface so as to select plural sensing units from a sensing unit group; creating a unlocking information according to the setting operation, wherein the unlocking information includes an enabling sequence of the selected sensing units; making the unlocking information associated with the operation function. After finishing the setting procedure of safety mechanism, when a trigger event conforming to the unlocking information is received, the operation corresponding to the unlocking information is executed.

First claim

What is claimed is:

1. A method of operating an electronic apparatus, wherein the electronic apparatus comprises a sensing unit group having a plurality of sensors, a boot firmware, a power key, a touch screen, and a controller coupled to the power key, the boot firmware and the touch screen, and the method comprises:
receiving a setting operation corresponding to a specific operation behavior through a setting interface of the electronic apparatus so as to select a plurality of ones among the sensors in the sensing unit group;
creating an unlocking information according to the setting operation, wherein the unlocking information comprises an enabling sequence of the selected sensors;
delivering a notice signal to the boot firmware by the controller if the controller receives a power-enabling signal from the power supply when the electronic apparatus is under a shutdown mode state;
displaying a prompt message at the touch screen through the boot firmware;
receiving a trigger event, wherein the trigger event is generated by the sensors selected in the sensing unit group to sense the specific operation behavior of a user;
judging whether or not the trigger event conforms to the unlocking information; and
when the trigger event conforms to the unlocking information, judging whether or not receiving the power-enabling signal once again from the power supply within a preset time period after the trigger event conforming to the unlocking information;
executing a boot action through the boot firmware if receiving the power-enabling signal within the preset time period; and
displaying the prompt message at the touch screen through the boot firmware if not receiving the power-enabling signal within the preset time period.

2. The method according to claim 1 , wherein before the step of receiving the trigger signal, further comprises: executing a setting procedure of safety mechanism, and the setting procedure of safety mechanism comprises:
making the unlocking information associated with the operation function.

3. The method according to claim 2 , wherein the setting interface comprises a plurality of setting items wherein the quantity of the setting items is corresponding to the quantity of the sensors of the sensing unit group, the setting items respectively have a corresponding identifying information, and relative positions of the setting items in the setting interface are corresponding to real relative positions of the sensors comprised by the sensing unit group at the electronic apparatus;
wherein the step of creating the unlocking information according to the setting operation comprises:
selecting a plurality of selected items among the setting items according to the setting operation and obtaining the identifying information corresponding to each of the selected items;
detecting a selecting sequence of the selected items; and
setting the enabling sequence of the selected sensors according to the selecting sequence.

4. The method according to claim 3 , wherein the unlocking information further comprises a sensitive time of each of the selected sensors, and the step of creating the unlocking information according to the setting operation further comprises:
setting the sensitive time according to a staying time by selecting each of the selected items.

5. The method according to claim 2 , further comprising:
executing the setting procedure of safety mechanism through a boot firmware; and
storing the unlocking information into a first memory of a controller.

6. The method according to claim 2 , further comprising:
displaying the setting interface on the touch screen so as to receive the setting operation through the touch screen.

7. The method according to claim 2 , further comprising:
starting an application after entering an operation system so as to execute the setting procedure of safety mechanism through the application; and
storing the unlocking information into a second memory of the electronic apparatus.

8. The method according to claim 7 , further comprising: after the step of starting the application,
receiving a login information corresponding to a software through the setting interface; and
storing the login information into the second memory.

9. The method according to claim 1 , wherein when the electronic apparatus is under the shutdown mode state, an power supply supplies power to the controller and the boot firmware; when the electronic apparatus is under the shutdown mode state and if the power key receives the power-enabling signal, the method further comprises:
supplying power to the sensing unit group from the power supply.

10. The method according to claim 1 , wherein after the step of judging whether or not the trigger event conforming to the unlocking information, the method further comprises:
promoting providing a warning signal when the trigger event does not conform to the unlocking information.
