Abstract

There is provided a user interface which enables a reduction in the chance of occurrence of erroneous operation. A display used for displaying various items of information, a captured image, or the like, is provided in the back of a digital camera. A first touch strip and a second touch strip, which detect sliding actions of the user'"'"'s fingers, are provided on respective sides of the display. A control section displays on a display screen a plurality of items required to perform menu setting, and switches between a selection position for a first-level hierarchical item according to sliding action detected by the first touch strip and a selection position for a second-level hierarchical item according to sliding action detected by the second touch strip.

Claims

1. A user interface which is provided in a portable electronic device, provides a user with information, and accepts operation from the user, the interface comprising:

a display screen for displaying information;

first and second slide detection units which form a pair for detecting sliding action of a user'"'"'s finger and placed in the vicinity of right and left side edges of a display screen; and

a control unit which displays a plurality of items on the display screen and sequentially switches a selection position of an item according to the sliding action detected by the slide detection units.

2. The user interface according to claim 1, wherein the plurality of items are classified into a plurality of hierarchical strata;

and

the control unit sequentially switches a selection position of an odd-numbered hierarchical layer according to sliding action detected by the first slide detection unit and sequentially switches a selection position of an even-numbered hierarchical layer according to sliding action detected by the second slide detection unit.

3. The user interface according to claim 2, wherein the first and second slide detection units can detect previously-defined determination operation;

and

the control unit specifies, as a determination item, a high-level hierarchical item selected at a point in time when the slide detection unit corresponding to the high-level hierarchical item has detected determination operation, and displays low-level hierarchical items corresponding to the determination item.

4. The user interface according to claim 3, wherein, when a slide detection unit corresponding to a high-level hierarchical item has detected sliding action during display of low-level hierarchical items, the control unit aborts the display of the low-level hierarchical items and sequentially switches selection position of a high-level hierarchical item according to the sliding action.

5. The user interface according to claim 2, wherein the control unit displays low-level hierarchical items corresponding to an item selected at a point in time when one is selected from the high-level hierarchical items.

6. The user interface according to claim 1, wherein the control unit displays the plurality of items arranged in an array on the display screen, moves the selection position of an item in a first direction according to the sliding action detected by the first slide detection unit, and moves the selection position of an item in a second direction differing from the first direction according to the sliding action detected by the second slide detection unit.

7. The user interface according to claim 1, further comprising:

a vibration unit which vibrates the overall user interface in synchronism with operation of the user detected by the respective slide detection units.

8. The user interface according to claim 5, wherein the vibration unit changes at least one of amplitude and frequency of vibrations according to the speed of detected sliding action of the user.

9. The user interface according to claim 1, further comprising a plurality of luminous elements disposed in the vicinity of the first slide detection unit and the second slide detection unit, wherein

the control unit causes a luminous element, which is located in the vicinity of a slide detection unit and is desired to be actuated by the user, to illuminate according to the state of current operation, thereby guiding user'"'"'s operation.

10. A digital camera having a display screen, comprising:

a release button for accepting an imaging command from a user;

first and second slide detection units which form a pair for detecting sliding action of a user'"'"'s finger and are placed in the vicinity of right and left side edges of a display screen; and

a control unit which displays on the display screen a plurality of items classified into a plurality of hierarchical strata, sequentially switches a selection position of an odd-numbered hierarchical item according to the sliding action detected by the first slide detection unit, and sequentially switches a selection position of an even-numbered hierarchical item according to sliding action detected by the second slide detection unit, wherein

the first slide detection unit is located more distance from the release button than is the second slide detection unit.
