Electronic device and method for executing function according to stroke input

1. An electronic device comprising:

at least one sensor;

a touchscreen display;

a speaker; and

a processor operatively connected to the at least one sensor and the touchscreen display, wherein the processor is configured to:

output a plurality of menu icons respectively having sequence numbers on the touchscreen display;

sense a stroke input using at least one of the at least one sensor and the touchscreen display;

identify a movement direction and a number of movements on a screen output on the touchscreen display in response to the sensed stroke input;

specify a menu icon corresponding to a result of moving by the number of movements from a reference menu icon among the plurality of menu icons in the movement direction, wherein the moving includes a shift in a sequence number indicating the menu icon, wherein the number of movements includes a sequence number difference between the reference menu icon and the specified menu icon; and

output information of the specified menu icon through the speaker.

2. The electronic device of claim 1 , wherein the processor is configured to:

switch a mode to a stroke input mode when sensing a specified motion input of an external object using at least one of the at least one sensor and the touchscreen display; and

sense the stroke input using at least one of the at least one sensor and the touchscreen display in the stroke input mode.

3. The electronic device of claim 1 , wherein the processor is configured to:

determine whether there is a previously specified menu icon among the plurality of menu icons; and

determine a first menu icon among the plurality of menu icons as the reference menu icon when there is no previously specified menu icon.

4. The electronic device of claim 1 , wherein the processor is configured to:

determine whether there is a previously specified menu icon among the plurality of menu icons; and

determine the previously specified menu icon as the reference menu icon when the previously specified menu icon is present.

5. The electronic device of claim 1 , wherein the processor is configured to:

determine whether there is no previously specified menu icon among the plurality of menu icons when information corresponding to a number is included in the stroke input;

determine a result of subtracting a specified number from the number as the number of movements when there is no previously specified menu icon; and

determine the number as the number of movements when the previously specified menu icon is present.

6. The electronic device of claim 1 , wherein the processor is configured to:

when the sensed stroke input contains information for specifying the movement direction, differently apply the movement direction based on the information for specifying the movement direction.

7. The electronic device of claim 1 , wherein the processor is further configured to:

when the sensed stroke input contains an alphabet or a Hangul initial consonant, identify at least one menu icon starting with the alphabet or the Hangul initial consonant among the plurality of menu icons; and

determine one of the at least one menu icon as the specified menu icon.

8. The electronic device of claim 7 , wherein the processor is configured to:

when a previously specified menu icon is present among the at least one menu icon, determine a menu icon of a following sequence number of the previously specified menu icon among the at least one menu icon as the specified menu icon.

9. The electronic device of claim 1 , wherein the processor is configured to:

execute a function corresponding to the specified menu icon when sensing a motion input of an external object after sensing the stroke input; and

output audio information associated with the function through the speaker.

10. The electronic device of claim 1 , wherein the processor is configured to:

when sensing a first motion input of an external object after sensing the stroke input, change the specified menu icon in response to the first motion input and output information of the changed menu icon.

11. The electronic device of claim 1 , wherein the processor is configured to:

when the plurality of menu icons are menu icons contained in one of a plurality of pages respectively having different sequence numbers, and when sensing a second motion input of an external object after sensing the stroke input,

display, on the display, a page corresponding to a result of moving by the number of movements based on at least one input in a movement direction based on the second motion input; and

output information of the displayed page through the speaker.

12. The electronic device of claim 1 , wherein the processor is configured to:

selectively execute at least one of specifying a menu icon or moving a page based on a change in sense area between the stroke input and a second motion input or the movement direction of the second motion input.

13. A method for executing, by at least one processor, a function based on a stroke input, the method comprising:

outputting a plurality of menu icons respectively having sequence numbers on a touchscreen display;

sensing the stroke input using at least one of at least one sensor and the touchscreen display;

identifying a movement direction and a number of movements on a screen output on the touchscreen display in response to the sensed stroke input;

specifying a menu icon corresponding to a result of moving by the number of movements from a reference menu icon among the plurality of menu icons in the movement direction, wherein the moving includes a shift in a sequence number indicating the menu icon, wherein the number of movements includes a sequence number difference between the reference menu icon and the specified menu icon; and

outputting information of the specified menu icon through a speaker.

14. The method of claim 13 , wherein the sensing of the stroke input includes:

switching a mode to a stroke input mode when sensing a specified motion input of an external object using at least one of the at least one sensor and the touchscreen display; and

sensing the stroke input using at least one of the at least one sensor and the touchscreen display in the stroke input mode.

15. The method of claim 13 , wherein the specifying of the menu icon includes:

determining whether there is a previously specified menu icon among the plurality of menu icons;

determining a first menu icon among the plurality of menu icons as the reference menu icon when there is no previously specified menu icon; and

determining the previously specified menu icon as the reference menu icon when the previously specified menu icon is present.
