## Abstract

An electronic device includes a display, an acceleration sensor, and a processing unit. The acceleration sensor detects displacement information of the electronic device. The processing unit compares the displacement information with an initial orientation information of the electronic device to determine directional movement of the electronic device. The processing unit shifts content of a display of the electronic device according to the directional movement.

## Claims

### Claim 1

An electronic device, comprising:
a display;
an acceleration sensor that detects an initial orientation information of the electronic device and a displacement information of the electronic device when the electronic device is used; and
a processing unit electronically connected to the acceleration sensor, wherein the processing unit compares the displacement information with the initial orientation information to determine directional movement of content of the display relative to the displacement, and adjust position of the content on the display according to the directional movement in an opposite direction of the displacement of the electronic device such that the content of the display remains in an original position.

### Claim 2 (depends on 1)

The electronic device of claim 1, wherein the directional movement of content of the display includes direction and distance of a shift of the content on the display.

### Claim 3 (depends on 1)

The electronic device of claim 1, wherein the displacement information includes up and down and side to side movements of the electronic device.

### Claim 4 (depends on 1)

The electronic device of claim 1, wherein the initial orientation information is a baseline position of the electronic device.

### Claim 5

A display adjustment method for adjusting content displayed on a display of an electronic device comprising an acceleration sensor, the method comprising:
detecting an initial orientation information of the electronic device by the acceleration sensor;
detecting displacement information of the electronic device by the acceleration sensor;
comparing the displacement information with the initial orientation information to determine whether the device has been displaced;
if the displacement of the electronic device falls outside a predefined range, determining how the content of the display should be shifted to compensate for the displacement;
adjusting the content displayed in an opposite direction of the displacement of the electronic device, thereby making the content remain in an original position.

### Claim 6 (depends on 5)

The method of claim 5, further including feedbacking to step of detecting the displacement information of the electronic device, if the device is not displaced or a displacement is within the predefined range.

### Claim 7 (depends on 5)

The method of claim 5, further including sending the initial orientation information to a storage unit before detecting the displacement information of the electronic device.
