Abstract

Angle-based item determination methods and systems are provided. First, the orientation of an electronic device is detected via at least one sensor. An included angle between a specific axis of the electronic device and a specific direction is obtained. Then, one of a plurality of items is determined according to the included angle.

Claims

1. An angle-based item determination method for use in an electronic device, comprising:

detecting the orientation of the electronic device via at least one sensor;

obtaining a first included angle between a specific axis of the electronic device and a specific direction at a first time point;

obtaining a second included angle between the specific axis of the electronic device and the specific direction at a second time point;

calculating an angle difference according to the first included angle and the second included angle; and

determining one of a plurality of items according to the angle difference.

2. The method of claim 1, further comprising receiving an instruction, and in response to the instruction, the first included angle between the specific axis of the electronic device and the specific direction at the first time point is recorded.

3. The method of claim 2, further comprising:

determining whether the orientation of the electronic device matches with or substantially matches with a specific orientation, or whether a movement of the electronic device matches with or substantially matches with a specific movement; and

generating the instruction when the orientation of the electronic device matches with or substantially matches with the specific orientation, or when the movement of the electronic device matches with or substantially matches with the specific movement.

4. The method of claim 1, wherein the specific direction comprises a direction of gravity, or a geographical direction.

5. The method of claim 1, further comprising displaying the determined item in a user interface via a display unit.

6. The method of claim 1, further comprising activating the determined item in the electronic device.

7. The method of claim 1, wherein the items are arranged in a specific order, and the greater the angle difference, the item closer to last in the specific order is determined.

8. The method of claim 1, wherein the at least one sensor comprises a compass, an accelerometer, or a Gyro sensor.

9. An angle-based item determination system for use in an electronic device, comprising:

at least one sensor detecting the orientation of the electronic device;

a storage unit comprising a plurality of items; and

a processing unit obtaining a first included angle between a specific axis of the electronic device and a specific direction at a first time point, obtaining a second included angle between the specific axis of the electronic device and the specific direction at a second time point, calculating an angle difference according to the first included angle and the second included angle, and determining one of a plurality of items according to the angle difference.
