Abstract

An auxiliary input method for an electronic device displays a virtual keyboard input interface optionally on a screen of the electronic device according to an external ambient brightness state of the electronic device, so as to assist the users to input data. The method includes sensing current ambient brightness to obtain an ambient brightness value; comparing the ambient brightness value with a preset brightness value; if the ambient brightness value is lower than the preset brightness value, calculating a duration in which the ambient brightness value is lower than the preset brightness value; comparing the duration with the preset time; if the duration reaches the preset time, displaying the virtual keyboard input interface on the screen of the electronic device, thereby improving the operation convenience of the electronic device.

Claims

1. An auxiliary input method for an electronic device, comprising:

(a) sensing a current ambient brightness, so as to obtain an ambient brightness value;

(b) comparing the ambient brightness value with a preset brightness value; and

(c) if the ambient brightness value is lower than the preset brightness value, displaying a virtual keyboard input interface on a screen of the electronic device.

2. The auxiliary input method for an electronic device as claimed in claim 1, wherein the step (c) further comprises:

(c1) calculating a duration in which the ambient brightness value is lower than the preset brightness value;

(c2) comparing the duration with a preset time; and

(c3) if the duration reaches the preset time, displaying the virtual keyboard input interface on a screen of the electronic device.

3. The auxiliary input method for an electronic device as claimed in claim 2, after the step (c3), further comprising:

receiving a key value input by a user; and

displaying a key pressing effect corresponding to the key value in the virtual keyboard input interface.

4. The auxiliary input method for an electronic device as claimed in claim 2, wherein if the duration does not reach to the preset time, return to the step (a).

5. The auxiliary input method for an electronic device as claimed in claim 1, wherein if the ambient brightness value is higher than or equal to the preset brightness value, return to the step (a).
