Abstract

A context awareness-based screen scroll method is provided. The method includes detecting information about surrounding circumstances of a terminal, setting a screen scroll mode based on the surrounding circumstances, detecting occurrence of an event corresponding to the set screen scroll mode, and executing screen scroll according to the occurred event.

Claims

1. A context awareness-based screen scroll method, the method comprising:

detecting information about surrounding circumstances of a terminal;

setting a screen scroll mode based on the surrounding circumstances;

detecting occurrence of an event corresponding to the set screen scroll mode; and

executing screen scroll according to the occurred event.

2. The method of claim 1, wherein the screen scroll mode includes at least one of a vision scroll mode based on a camera module, a motion scroll mode based on a sensor module, and a voice scroll mode based on an input/output module.

3. The method of claim 1, wherein the detecting of the information about surrounding circumstances comprises at least one of determining whether the terminal is fixed and determining whether ambient illuminance of the terminal is greater than or equal to a threshold.

4. The method of claim 1, wherein the detecting of the information about surrounding circumstances comprises at least one of determining whether the terminal is physically connected to a peripheral device and determining whether the terminal is left unattended.

5. The method of claim 2, wherein the vision scroll mode is set if the terminal is fixed, and the motion scroll mode is set if the terminal is not fixed.

6. The method of claim 2, wherein the vision scroll mode is set if ambient illuminance of the terminal is greater than or equal to a threshold, and the motion scroll mode is set if the ambient illuminance of the terminal is less than the threshold.

7. The method of claim 2, wherein the vision scroll mode is set if the terminal is fixed or ambient illuminance of the terminal is greater than or equal to a threshold, and the motion scroll mode is set if the ambient illuminance of the terminal is less than the threshold.

8. The method of claim 1, wherein the detecting of the occurrence of an event comprises:

determining whether a pre-registered subject is detected from an image captured by a camera module; and

determining whether a change in position of the detected subject exceeds a threshold in continuously captured images.

9. The method of claim 1, wherein the detecting of the occurrence of an event comprises:

determining whether a pre-registered subject is detected from an image captured by a camera module; and

determining whether a change in position or angle of the terminal exceeds a threshold.

10. The method of claim 9, further comprising stopping the screen scroll if the terminal moves or is tilted in a direction toward an initial position or an initial angular position before the change in position.

11. The method of claim 1, wherein the detecting of the occurrence of an event comprises:

detecting a face in an image;

detecting an interest region including a nose from the detected face; and

detecting a moving state of the interest region depending on a moving direction of the interest region,

wherein the screen scroll is executed depending on the moving state of the interest region.

12. The method of claim 11, wherein the moving state of the interest region is determined if the interest region has moved and stopped for a threshold time or during a threshold number of image frames.

13. The method of claim 11, wherein the moving state of the interest region is determined, if the interest region has moved and stopped for a threshold time or during a threshold number of image frames, after the stop state of the interest region was maintained for a threshold time or during a threshold number of image frames.

14. A terminal for providing context awareness-based screen scroll, the terminal comprising:

a display unit configured to provide a screen; and

a controller configured to detect information about surrounding circumstances of the terminal, to set a screen scroll mode based on the surrounding circumstances, to detect occurrence of an event corresponding to the set screen scroll mode, and to execute screen scroll according to the occurred event.

15. The terminal of claim 14, further comprising a camera module configured to output a captured image,

wherein the controller executes screen scroll if a registered subject is detected from the captured image.

16. The terminal of claim 15, further comprising a sensor module configured to detect a change in position or angle of the terminal,

wherein the controller determines whether a change in position or angle of the terminal exceeds a threshold.

17. The terminal of claim 16, further comprising an input/output module configured to detect a user'"'"'s voice,

wherein the screen scroll mode includes at least one of a vision scroll mode based on the camera module, a motion scroll mode based on the sensor module, and a voice scroll mode based on the input/output module.

18. A terminal for providing context awareness-based screen scroll, the terminal comprising:

a display unit configured to provide a screen;

a camera module configured to output a captured image; and

a controller configured to determine whether a face is detected from the captured image, and, if the face is detected from the captured image, to detect a tilt of the terminal and execute screen scroll based on a tilt direction of the terminal.

19. The terminal of claim 18, wherein the controller executes screen scroll if a tilt angle of the terminal is greater than or equal to a threshold.

20. The terminal of claim 19, wherein the controller stops the screen scroll if the terminal is tilted in an opposite direction to the tilt direction at a threshold angle or more.
