Abstract

According to one embodiment, a mobile terminal includes: a touchscreen configured to display a first menu and receive a plurality of touch inputs of a first pattern via the first menu and to display a second menu and receive a plurality of touch inputs of a second pattern via the second menu; and a controller configured to: calculate a first moving distance of a pointer for each of the received touch inputs of the first pattern; determine a minimum among the plurality of calculated first moving distances; calculate a second moving distance of the pointer for each of the received touch inputs of the second pattern; determine a maximum among the plurality of calculated second moving distances; and determine a threshold moving distance of the pointer for discriminating the touch input of the first pattern from the touch input of the second pattern by using the minimum and the maximum.

First claim

What is claimed is:

1. A mobile terminal comprising:
a touchscreen configured to:
display a first menu;
receive a plurality of touch inputs of a first pattern via the first menu;
display a second menu; and
receive a plurality of touch inputs of a second pattern via the second menu;

a memory configured to store a preset threshold moving distance of a pointer for discriminating the plurality of touch inputs of the first pattern from the plurality of touch inputs of the second pattern; and
a controller configured to:
determine whether each of the received plurality of touch inputs of the first pattern correspond to several guide information included in the first menu, the several guide information providing an interface indicating a moving direction of each of the plurality of touch inputs of the first pattern, wherein, when each of the received plurality of touch inputs of the first pattern correspond to respective ones of the several guide information, the controller is further configured to:
calculate a first moving distance of the pointer for each of the received plurality of touch inputs of the first pattern;
determine a minimum moving distance among the plurality of calculated first moving distances;
calculate a second moving distance of the pointer for each of the received plurality of touch inputs of the second pattern;
determine a maximum moving distance among the plurality of calculated second moving distances;
determine a new threshold moving distance of the pointer for discriminating the plurality of touch inputs of the first pattern from the plurality of touch inputs of the second pattern by using the determined minimum and maximum moving distance; and
replace the preset threshold moving distance in the memory with the determined new threshold moving distance if the maximum moving distance does not exceed a preset range; and
maintain the preset threshold moving distance if the maximum moving distance exceeds the preset range.

2. The mobile terminal of claim 1 , wherein:
each of the plurality of touch inputs of the first pattern comprises a flicking input; and
each of the plurality of touch input of the second pattern comprises a touch input for selecting an icon or a menu.

3. The mobile terminal of claim 2 , wherein the controller is further configured to treat the flicking input as an erroneous input if a flicking input moving direction changes at least once.

4. The mobile terminal of claim 1 , wherein the controller is further configured to determine the new threshold moving distance as an average of the minimum moving distance and the maximum moving distance.

5. The mobile terminal of claim 1 , wherein the controller is further configured to maintain the preset threshold moving distance if the maximum moving distance is greater than the minimum moving distance.

6. The mobile terminal of claim 1 , wherein the controller is further configured to maintain the preset threshold moving distance if the minimum moving distance exceeds the preset range.

7. The mobile terminal of claim 1 , wherein:
the touchscreen is further configured to receive a preset number of the plurality of touch inputs of the first pattern via the first menu; and
the controller is further configured to calculate an average value of pointer moving distances of the preset number of the plurality of touch inputs of the first pattern.

8. The mobile terminal of claim 1 , wherein the touchscreen is further configured to receive the plurality of touch inputs of the second pattern via the second menu during a plurality of preset time intervals.

9. The mobile terminal of claim 1 , wherein:
the touchscreen is further configured to receive a preset number of the plurality of touch inputs of the second pattern via the second menu; and
the controller is further configured to calculate an average value of pointer moving distances of the preset number of the plurality of touch inputs of the second pattern.

10. A method of controlling a mobile terminal, the method comprising:
storing, in a memory of the mobile terminal, a preset threshold moving distance of a pointer for discriminating a plurality of touch inputs of a first pattern from a plurality of touch inputs of a second pattern;
displaying, by a touchscreen of the mobile terminal, a first menu for receiving the plurality of touch inputs of the first pattern; and
determining by the controller whether each of the received plurality of touch inputs of the first pattern correspond to several guide information included in the first menu, the several guide information providing an interface indicating a moving direction of each of the plurality of touch inputs of the first pattern, wherein, when each of the received plurality of touch inputs of the first pattern correspond to respective ones of the several guide information, further comprising:
displaying, by the touchscreen, a second menu for receiving the plurality of touch inputs of the second pattern;
calculating, by the controller, a first moving distance of the pointer for each of the received plurality of touch inputs of the first pattern;
determining, by the controller, a minimum moving distance among the plurality of calculated first moving distances;
calculating, by the controller, a second moving distance of the pointer for each of the received plurality of touch inputs of the second pattern;
determining, by the controller, a maximum moving distance among the plurality of calculated second moving distances;
determining, by the controller, a new threshold moving distance of the pointer for discriminating the plurality of touch inputs of the first pattern from the plurality of touch inputs of the second pattern by using the determined minimum and maximum moving distance; and
replacing the preset threshold moving distance in the memory with the determined new threshold moving distance if the maximum moving distance does not exceed a preset range; and
maintaining, by the controller, the preset threshold moving distance if the maximum moving distance exceeds the preset range.

11. The method of claim 10 , wherein:
each of the plurality of touch inputs of the first pattern comprises a flicking input; and
each of the plurality of touch inputs of the second pattern comprises a touch input for selecting an icon or a menu.

12. The method of claim 11 , further comprising treating the flicking input as an erroneous input if a flicking input moving direction changes at least once.

13. The method of claim 10 , further comprising maintaining, by the controller, the preset threshold moving distance if the maximum moving distance is greater than the minimum moving distance.

14. The method of claim 10 , further comprising maintaining, by the controller, the preset threshold moving distance if the minimum moving distance exceeds the preset range.

15. The method of claim 10 , wherein determining the new threshold moving distance comprises determining an average of the minimum moving distance and the maximum moving distance.

16. The method of claim 10 , further comprising:
receiving a preset number of the plurality of touch inputs of the first pattern via the first menu; and
calculating an average value of pointer moving distances of the preset number of the plurality of touch inputs of the first pattern.

17. The method of claim 10 , further comprising receiving the plurality of touch inputs of the second pattern via the second menu during a plurality of preset time intervals.

18. The method of claim 10 , further comprising:
receiving a preset number of
