Abstract

A login control method and apparatus is provided for facilitating usage right authentication of a mobile terminal, when the user unlocks the mobile terminal. The login control method includes determining, when a lock image is displayed on a screen, a posture of a mobile terminal, detecting unlock information, comparing the unlock information with a pre-registered unlock information, selecting, when the unlock information and the pre-registered unlock information are identical, an operation mode corresponding to the matched unlock information, from a plurality of operation modes, as the current operation mode, and displaying an image representing the current operation mode.

First claim

What is claimed is:

1. A login control method, comprising:
determining, when a lock image is displayed on a screen, a posture of a mobile terminal;
detecting unlock information;
comparing the detected unlock information with registered unlock information;
selecting, when the detected unlock information and the registered unlock information are identical to each other, an operation mode corresponding to the posture of the mobile terminal, from a plurality of operation modes, as a current operation mode;
determining at least one executable application corresponding to the current operation mode; and
displaying an image comprising at least one visual element corresponding to the at least one executable application,
wherein displaying the image comprises presenting, when the current operation mode is a limitless operation mode, a first image representing the limitless operation mode and, when the current operation mode is a limited operation mode, a second image representing the limited operation mode,
wherein the second image includes at least one visual element with the exception of at least one of visual elements included in the first image, and
wherein the posture of the mobile terminal is determined based on each of rotation angles relative to x- y- and z-axes, respectively.

2. The login control method of claim 1 , wherein the image representing the current operation mode comprises at least one of a visual element corresponding to an application and a visual element corresponding to content and, when the current operation mode is the limited operation mode, applications represented by the visual element corresponding to the application and content represented by the visual element corresponding to the content are limited in use.

3. The login control method of claim 1 , wherein the operation modes comprise the limitless operation mode allowing for use of all applications and content in the mobile terminal and at least one limited operation mode allowing for use of only preset applications and contents among all applications and content.

4. A mobile terminal, comprising:
a display unit;
a sensor configured to sense a posture of the mobile terminal; and
processor configured to:
determine a posture of the mobile terminal based on sensing information provided by the sensor;
detect unlock information when a lock image is displayed on a screen of the display unit;
compare the detected unlock information with registered unlock information;
select, when the detected unlock information and the registered unlock information are identical to each other, an operation mode corresponding to the posture of the mobile terminal among a plurality of registered unlock operation modes as a current operation mode of the mobile terminal;
determine at least one executable application corresponding to the current operation mode; and
control the display unit to display an image related to the current operation mode,

wherein the processor controls the display unit to display, when the current operation mode is a limitless operation mode, a first image representing the limitless operation mode and, when the current operation mode is a limited operation mode, a second image representing the limited operation mode,
wherein the second image includes at least one visual element with the exception of at least one of visual elements included in the first image, and
wherein the sensing information includes each of rotation angles relative to x- y- and z-axes, respectively.

5. The mobile terminal of claim 4 , wherein the image related to the current operation mode comprises at least one of a visual element corresponding to an application and a visual element corresponding to content and, when the current operation mode is the limited operation mode, applications represented by the visual element corresponding to the application and content represented by the visual element corresponding to the content are limited in use.

6. The mobile terminal of claim 4 , wherein the operation modes comprise the limitless operation mode allowing for use of all applications and content in the mobile terminal and at least one limited operation mode allowing for use of only preset applications and content among all applications and content.

7. The mobile terminal of claim 4 , wherein the processor detects the unlock information through at least one of a touch panel, a key input unit, and a microphone.
