Abstract

An electronic device includes a display section that displays an object; a touch panel that detects a touch input manipulation; a touch determination section that determines a type and a direction of the touch input manipulation performed on the object; and a scroll control unit that performs a first inertial scroll of the object in a direction of flicking manipulation when the touch determination section determines that that flicking manipulation is performed on the object without performing slide manipulation on the object, and a second inertial scroll of the object that is longer in scroll distance and faster in scroll speed than the first inertial scroll when the touch determination section determines that slide manipulation is performed on the object and then the flicking manipulation is performed on the object in a direction opposite to the direction of the slide manipulation.

Claims

1. An electronic device, comprising:

a display section that displays an object;

a touch panel that detects a touch input of an indicator;

a touch determination circuit that determines a manipulation instructed by the detected touch input; and

a scroll control circuit that performs, when a manipulation including a flicking of the indicator in a predetermined scrolling direction is determined to be instructed, scrolling the object in a direction corresponding to the predetermined scrolling direction, wherein,

when a special scrolling manipulation is determined to be instructed, the scrolling in the direction corresponding to the predetermined scrolling direction is performed faster and/or for a longer distance than when a normal scrolling manipulation is determined to be instructed,

the special scrolling manipulation is a flicking of the indicator in the predetermined scrolling direction for a flicking distance to a first threshold following a sliding of the indicator in a direction opposite to the predetermined scrolling direction for a sliding distance longer than a second predetermined threshold, during the sliding of the indicator in the direction opposite to the predetermined scrolling direction the object scrolls in the direction opposite to the direction corresponding to the predetermined scrolling direction, the flicking distance to the first threshold having a length less than the sliding distance longer than the second predetermined threshold, and

the normal scrolling manipulation is a flicking of the indicator in the predetermined scrolling direction without following a sliding of the indicator in the direction opposite to the predetermined scrolling direction for the sliding distance longer than the second predetermined threshold.

2. The electronic device according to claim 1, comprising

a storage for temporarily storing the display information about the object, wherein

the display section displays the object temporarily stored in the storage.

3. The electronic device according to claim 1, wherein the scroll control circuit changes, when the special scrolling manipulation is determined to be instructed, the speed and/or distance of the scrolling according to the distance of the sliding performed before the flicking.

4. The electronic device according to claim 1, wherein

the display section displays a fiducial object indicating the first threshold, and

the touch determination circuit determines the special scrolling manipulation is instructed when the sliding of the indicator is followed by the flicking which straddles the fiducial object.

5. The electronic device according to claim 4, wherein the display section displays a plurality of fiducial objects, each of which indicates a different predetermined threshold, and

the scroll control circuit changes the speed and/or distance of the scrolling according to which of the plurality of the fiducial objects is straddled during the flicking of the indicator after the sliding of the indicator.

6. The electronic device according to claim 1, further comprising:

a jumping control circuit that performs jumping to a predetermined position when a jumping manipulation is determined to be instructed,

wherein the jumping manipulation is a flicking of the indicator in a jumping direction following a sliding of the indicator in a direction opposite to the jumping direction for a distance longer than a predetermined threshold.

7. The electronic device according to claim 6, wherein the jumping control circuit changes, when the jumping manipulation is determined to be instructed, the amount of jumping according to a distance of the sliding performed before the flicking.

10. The electronic device according to claim 6, wherein,

the jumping direction is the same as the predetermined scrolling direction, and

the touch determination section distinguishes the special scrolling manipulation and the jumping manipulation according to whether the sliding of the indicator followed by the flicking of the indicator is performed on a specific object.

11. The electronic device according to claim 10, wherein,

the specific object is a scroll bar, and

the touch determination section determines the jumping manipulation is instructed when the sliding of the indicator followed by the flicking of the indicator is performed on the scroll bar.

12. The electronic device according to claim 6, wherein, the jumping direction is different from both the predetermined scrolling direction and the opposite direction to the predetermined scrolling direction.

13. The electronic device according to claim 1, wherein the indicator is a finger.

14. The electronic device of claim 1, wherein during the special scrolling manipulation, the indicator remains in contact with the touch panel until an end of the flicking of the indicator.

8. A method of controlling a display, comprising the steps of:

detecting a touch input of an indicator by a touch panel;

displaying an object on a display section;

determining a manipulation instructed by the detected touch input;

performing, when a manipulation including a flicking of the indicator in a predetermined scrolling direction is determined to be instructed, scrolling the object in a direction corresponding to the predetermined scrolling direction, wherein,

when a special scrolling manipulation is determined to be instructed, the scrolling in the direction corresponding to the predetermined scrolling direction is performed faster and/or for a longer distance than when a normal scrolling manipulation is determined to be instructed,

the special scrolling manipulation is a flicking of the indicator in the predetermined scrolling direction for a flicking distance to a first threshold following a sliding of the indicator in a direction opposite to the predetermined scrolling direction for a sliding distance longer than a second predetermined threshold, during the sliding of the indicator in the direction opposite to the predetermined direction the object scrolls in the direction opposite to the direction corresponding to the predetermined direction, the flicking distance to the first threshold having a length less than the sliding distance longer than the second predetermined threshold, and

the normal scrolling manipulation is a flicking of the indicator in the predetermined scrolling direction without following a sliding of the indicator in the direction opposite to the predetermined scrolling direction for the sliding distance longer than the second predetermined threshold.

9. A non-transitory computer-readable storage medium in which is stored a program for causing a computer to execute the steps of:

detecting a touch input of an indicator by a touch panel;

displaying an object on a display section;

determining a manipulation instructed by the detected touch input;

performing, when a manipulation including a flicking of the indicator in a predetermined scrolling direction is determined to be instructed, scrolling the object in a direction corresponding to the predetermined scrolling direction, wherein,

when a special scrolling manipulation is determined to be instructed, the scrolling in the direction corresponding to the predetermined scrolling direction is performed faster and/or for a longer distance than when a normal scrolling manipulation is determined to be instructed,

the special scrolling manipulation is a flicking of the indicator in the predetermined scrolling direction to a first threshold following a sliding of the indicator in a direction opposite to the predetermined scrolling direction for a sliding distance longer than a second predetermined threshold, during the sliding of the indicator in the direction opposite to the predetermined scrolling direction, the object scrolls in the direction opposite to the direction corresponding to the predetermined scrolling direction, the flicking distance to the first threshold having a length less than the sliding distance longer than the second predetermined threshold, and

the normal scrolling manipulation is a flicking of the indicator in the predetermined scrolling direction without following a sliding of the indicator in the direction opposite to the predetermined scrolling direction for the sliding distance longer than the second predetermined threshold.
