Abstract

A mobile terminal and a control method are provided. The mobile terminal includes: a body formed to wrap around at least one region of a wrist; a projection unit disposed to the side of the body and projecting image information; a display unit disposed on a front surface of the body and configured to output first screen information; and a controller configured to control the projection unit to project screen information corresponding to first screen information currently displayed on the display unit, on the basis of a pre-set type touch applied to the display unit.

Claims

1. A mobile terminal comprising:

a body formed to wrap around at least one region of a wrist;

a projection unit disposed to the side of the body and projecting image information;

a display unit disposed on a front surface of the body and configured to output first screen information; and

a controller configured to control the projection unit to project screen information corresponding to first screen information currently displayed on the display unit, on the basis of a pre-set type touch applied to the display unit.

2. The mobile terminal of claim 1, wherein when an event is received, the controller displays event information related to the received event together with the first screen information on the display unit, and

when the touch is applied to the display unit, the controller projects the screen information corresponding to the first screen information through the projection unit and outputs second screen information corresponding to the event information to the display unit.

3. The mobile terminal of claim 2, wherein the event information is displayed to overlap with the first screen information, and the second screen information is displayed on the entirety of the display unit.

4. The mobile terminal of claim 2, wherein only when the touch is applied to a region in which the first screen information is displayed, the controller outputs the screen information corresponding to the first screen information through the projection unit.

5. The mobile terminal of claim 4, wherein when the touch is applied to a region in which the event information is displayed, the controller projects the second screen information through the projection unit and continuously displays the first screen information on the display unit.

6. The mobile terminal of claim 1, wherein in the case in which the screen information corresponding to the first screen information is projected through the projection unit, the second screen information, which was output to the display unit before the first screen information was displayed, is output again.

7. The mobile terminal of claim 6, wherein the screen information corresponding to the first screen information is the first screen information itself or summary information of the first screen information.

8. The mobile terminal of claim 1, wherein the projection unit includes a plurality of projectors, and

the screen information corresponding to the first screen information is projected through a projector placed in a position corresponding to a direction in which the touch is applied, among the plurality of projectors.

9. The mobile terminal of claim 8, wherein the controller controls the projection unit such that at least one of a format, a type and a output position in which the screen information corresponding to the first screen information is projected is varied according to a direction in which the touch is applied.

10. The mobile terminal of claim 9, wherein when the touch is applied in a first direction, the screen information corresponding to the first screen information is output through the first projector among the plurality of projectors, and

when the touch is applied in a second direction different from the first direction, the screen information corresponding to the first screen information is output through a second projector different from the first projector among the plurality of projectors, and

the screen information corresponding to the first screen information projected through the first projector is summary information of the first screen information, and

the screen information corresponding to the first screen information projected through the second projector is the first screen information itself.

11. The mobile terminal of claim 1, wherein when a pre-set type touch is applied to the screen information corresponding to the first screen information projected through the projection unit, the controller outputs again the first screen information to the display unit in response.

12. The mobile terminal of claim 1, wherein when the screen information corresponding to the first screen information is projected through the projection unit, the second information different from the first screen information is displayed on the display unit, and

when the touch is applied again to the display unit, while the second information is being displayed on the display unit,

the controller controls the projection unit to project the screen information corresponding to the second screen information together with the screen information corresponding to the first screen information therethrough.

13. The mobile terminal of claim 12, wherein when one of the screen information corresponding to the second screen information and the screen information corresponding to the first screen information is dragged to the other, the controller processes functions corresponding to the first screen information and the second screen information in an associated manner in response.

14. The mobile terminal of claim 1, wherein the screen information projected through the projection unit is displayed on a wrist or a back of a hand excluding the region wrapped with the body of the mobile terminal, and

the controller controls the projection unit to vary a display size of the screen information corresponding to the first screen information according to an area of the wrist or the back of a hand.

15. The mobile terminal of claim 1, wherein in a case in which the screen information corresponding to the first screen information is displayed on the back of a hand, when the back of a hand is bent, the controller controls the projection unit to terminate projection of the screen information corresponding to the first screen information in response.

16. The mobile terminal of claim 1, wherein when the pre-set type touch is a pinch-in touch, the first screen information is displayed in a magnified manner through the projection unit and the display unit.

17. A control method of a mobile terminal including a body and a projection unit disposed on the side of the body, the method comprising:

outputting first screen information to a display unit disposed on a front surface of the body;

sensing a pre-set type touch applied to the display unit; and

projecting the screen information corresponding to the first screen information, which has been output to the display unit, through the projection unit in response to the sensed touch, and outputting second screen information different from the first screen information to the display unit.

18. The control method of claim 17, when an event is received, event information related to the received event is displayed together with the first screen information on the display unit, and when the touch is applied, the screen information corresponding to the first screen information is projected through the projection unit and second screen information corresponding to the event information is displayed on the display unit.
