Abstract

An electronic device sets an initial position of an electronic device as a reference position. The electronic device uses a gravity sensor to acquire a tilt angle of the electronic device based on a current position of the electronic device and the reference position and a tilt direction of the electronic device. The electronic device determines a scrolling speed and a scrolling direction of a data page displayed on a screen of the electronic device according to the tilt angle and the tilt direction, and controls movements of the data page according to the scrolling speed and the scrolling direction.

Claims

1. A method being executed by a processor of an electronic device comprising a screen, the method comprising:

(a) in response to receiving a start signal to control display of a data page displayed on the screen of the electronic device, setting an initial position of the electronic device as a reference position;

(b) using a gravity sensor to acquire a tilt angle of the electronic device based on a current position of the electronic device and the reference position and a tilt direction of the electronic device;

(c) determining a scrolling speed and a scrolling direction of the data page displayed on the screen according to the tilt angle and the tilt direction of the electronic device; and

(d) controlling movements of the data page on the screen according to the scrolling speed and the scrolling direction.

2. The method as claimed in claim 1, wherein the method further comprising:

in response to receiving a stop signal for inactivating the function of automatically controlling the display of the data page on the electronic device, controlling the data page to stop scrolling.

3. The method as claimed in claim 1, wherein step (b) comprises:

determining the tilt angle is a positive value if the electronic device is tilted down from the reference position; and

determining the tilt angle is a negative value if the electronic device is tilted up from the reference position.

4. The method as claimed in claim 3, wherein step (c) comprising:

determining that the data page should be scrolled down on the screen if the tilt angle is positive; and

determining that the data page should be scrolled up on the screen if the tilt angle is negative.

5. The method as claimed in claim 1, wherein step (c) comprises:

determining the scrolling speed according to a formula V=S*V_m, wherein V_m represents a preset maximal scrolling speed, V represents the scrolling speed of the data page, and the coefficient S is set according to the tilt angle.

6. A non-transitory storage medium storing a set of instructions, the set of instructions capable of being executed by a processor of an electronic device comprising a screen, to perform a method for automatically controlling a display of the screen on the electronic device, the method comprising:

(a) in response to receiving a start signal to control display of a data page displayed on the screen of the electronic device, setting an initial position of the electronic device as a reference position;

(b) using a gravity sensor to acquire a tilt angle of the electronic device based on a current position of the electronic device and the reference position and a tilt direction of the electronic device;

(c) determining a scrolling speed and a scrolling direction of the data page displayed on the screen according to the tilt angle and the tilt direction of the electronic device; and

(d) controlling movements of the data page on the screen according to the scrolling speed and the scrolling direction.

7. The non-transitory storage medium as claimed in claim 6, wherein the method further comprising:

in response to receiving a stop signal for inactivating the function of automatically controlling the display of the data page on the electronic device, controlling the data page to stop scrolling.

8. The non-transitory storage medium as claimed in claim 6, wherein step (b) comprises:

determining the tilt angle is a positive value if the electronic device is tilted down from the reference position; and

determining the tilt angle is a negative value if the electronic device is tilted up from the reference position.

9. The non-transitory storage medium as claimed in claim 8, wherein step (c) comprising:

determining that the data page should be scrolled down on the screen if the tilt angle is positive; and

determining that the data page should be scrolled up on the screen if the tilt angle is negative.

10. The non-transitory storage medium as claimed in claim 6, wherein step (c) comprises:

determining the scrolling speed according to a formula V=S*V_m, wherein V_m represents a preset maximal scrolling speed, V represents the scrolling speed of the data page, and the coefficient S is set according to the tilt angle.

11. An electronic device, the electronic device comprising:

a gravity sensor;

a screen;

a storage unit;

at least one processor;

one or more programs that are stored in the storage unit and are executed by the at least one processor, the one or more programs comprising;

a setting module that sets an initial position of the electronic device as a reference position, in response to receiving a start signal to control display of a data page displayed on the screen of the electronic device;

an acquisition module that acquires a tilt angle of the electronic device based on a current position of the electronic device and the reference position and a tilt direction of the electronic device from the gravity sensor;

a determination module that determines a scrolling speed and a scrolling direction of the data page displayed on the screen according to the tilt angle and the tilt direction of the electronic device; and

a control module that controls movements of the data page on the screen according to the scrolling speed and the scrolling direction.

12. The electronic device as claimed in claim 11, wherein the control module further controls the data page to stop scrolling in response to receiving a stop signal for inactivating the function of automatically controlling the display of the data page on the electronic device.

13. The electronic device as claimed in claim 11, wherein if the electronic device is tilted down from the reference position, the tilt angle is a positive value;

if the electronic device is tilted up from the reference position, the tilt angle is a negative value.

14. The electronic device as claimed in claim 13, wherein if the tilt angle is positive, the data page should be scrolled down on the screen;

if the tilt angle is negative, the data page should be scrolled up on the screen.

15. The electronic device as claimed in claim 11, wherein the scrolling speed of the data page is determined according to a formula V=S*V_m, wherein V_m represents a preset maximal scrolling speed, V represents the scrolling speed of the data page, and the coefficient S is set according to the tilt angle.
