Abstract

A method is provided for adjusting a touch screen display of a terminal, the method including adjusting, by a processor, a brightness level of the display based on a direction of a touch gesture performed in a predetermined region of the display; adjusting a contrast level of the display in response to a first characteristic included in the touch gesture, when the touch gesture progresses in a direction of increasing the brightness level; and adjusting a tone level of the display in response to a second characteristic included in the touch gesture, when the touch gesture progresses in a direction of decreasing the brightness level.

Claims

1. A method for adjusting a touch screen display of a terminal, the method comprising:

adjusting, by a processor, a brightness level of the display based on a direction of a touch gesture performed in a predetermined region of the display;

adjusting a contrast level of the display in response to a first characteristic included in the touch gesture, when the touch gesture progresses in a direction of increasing the brightness level; and

adjusting a tone level of the display in response to a second characteristic included in the touch gesture, when the touch gesture progresses in a direction of decreasing the brightness level.

2. The method of claim 1, further comprising:

determining whether the touch gesture possess one of the first characteristic and the second characteristic based on at least one of a location and a duration of a first touch that is part of the touch gesture.

3. The method of claim 1, further comprising increasing the contrast level in proportion to time for which a touch that is part of the touch gesture is maintained at a given location in the predetermined region.

4. The method of claim 2, further comprising increasing the contrast level in proportion to a distance between the first touch and a second touch that is part of the touch gesture.

5. The method of claim 4, wherein the second touch is outside of the predetermined region of the display.

6. The method of claim 2, further comprising outputting an indication that the terminal has transitioned into a complementary adjustment mode when it is determined that the touch gesture possesses one of the first characteristic and the second characteristic.

7. A method for controlling multiple properties of an electronic device'"'"'s display by using a single touch gesture, the method comprising:

responsive to detecting a touch gesture in a predetermined region of the display, entering by the electronic device into a primary adjustment mode, wherein the electronic device is configured to use the touch gesture as a basis for changing a first property of the display when the electronic device is in the primary adjustment mode; and

while the touch gesture is being performed, and responsive to detecting that the touch gesture possesses a predetermined characteristic, exiting the primary adjustment mode and entering a complementary adjustment mode by the electronic device, wherein the electronic device is configured to use the touch gesture as a basis for changing a second property of the display when the electronic device is in the complementary adjustment mode.

8. The method of claim 7, wherein the first property is one of a brightness level, a tone level, and a contrast level, and the second property is another one of the brightness level, tone level, and the contrast level.

9. The method of claim 7, further comprising determining whether the touch gesture possesses the predetermined characteristic based on a shift in a direction of the touch gesture.

10. The method of claim 7, further comprising determining whether the touch gesture possess the predetermined characteristic based on a first location of a first touch that is part of the touch gesture and a duration for which the first touch is maintained at the first location.

11. The method of claim 10, further comprising increasing a value of the second property in proportion to a distance between the first touch and a second touch that is part of the touch gesture.

12. The method of claim 11, wherein the second touch is performed at a second location outside of the predetermined region of the display.

13. The method of claim 7, further comprising increasing a value of the second property of the display in proportion to a duration for which a touch is maintained at a given location in the predetermined region of the display.

14. The method of claim 7, further comprising outputting, by the electronic device, an indication that the electronic device has transitioned into the complementary adjustment mode.

15. An apparatus comprising:

a display; and

a processor configured to;

responsive to detecting a touch gesture in a predetermined region of the display, enter into a primary adjustment mode, wherein the processor is operable to use the touch gesture as a basis for changing a first property of the display when the processor is in the primary adjustment mode; and

while the touch gesture is being performed, responsive to detecting that the touch gesture possesses a predetermined characteristic, exit the primary adjustment mode and enter a complementary adjustment mode, wherein the processor is operable to use the touch gesture as a basis for changing a second property of the display when the processor is in the complementary adjustment mode.

16. The apparatus of claim 15, wherein the first property is one of a brightness level, a tone level, and a contrast level, and the second property is another one of the brightness level, the tone level, and the contrast level.

17. The apparatus of claim 15, wherein the processor is further configured to determine whether the touch gesture possesses the predetermined characteristic based on a shift in a direction of the touch gesture.

18. The apparatus of claim 15, wherein the processor is further configured to determine whether the touch gesture possess the predetermined characteristic based on a first location of a first touch that is part of the touch gesture and a duration for which the first touch is maintained at the first location.

19. The apparatus of claim 18, wherein the processor is further configured to increase a value of the second property in proportion to a distance between the first touch and a second touch that is part of the touch gesture.

20. The apparatus of claim 19, wherein the processor is further configured to increase a value of the second property of the display in proportion to a duration for which a touch is maintained at a given location in the predetermined region of the display.
