Abstract

An operation method of a watch-type mobile terminal including a display unit according to an embodiment of the present invention comprises the steps of: recognizing a type of a bezel which is detachable from the display unit; receiving an input of at least one hard key included in the bezel; and performing a function corresponding to the type of the bezel on the basis of the received input.

First claim

The invention claimed is:

1. An operating method for a wearable mobile terminal comprising a main body including a display unit and a band coupled to the main body, the operating method comprising:
recognizing a bezel detachable from the display unit as at least a first bezel, a second bezel, or a third bezel based on at least one of a number of hard keys included in the bezel, positions of the hard keys on the bezel, a material of the bezel, or a color of the bezel;
performing a first function in response to a first input received via at least one hard key of the recognized first bezel; and
performing a second function in response to a second input received via at least one hard key of the recognized second bezel,
wherein the recognized third bezel includes three hard keys, and the method further comprises:
displaying a menu screen in response to a third input received via a first hard key of the third bezel;
displaying a home screen in response to a fourth input received via a second hard key of the third bezel; and
displaying a previous screen in response to a fifth input received via a third hard key of the third bezel.

2. The operating method of claim 1 , wherein:
the first bezel includes one hard key; and
the first function comprises turning on or off power of the mobile terminal, displaying the home screen or the menu screen, or displaying a setting screen.

3. The operating method of claim 1 , wherein:
the second bezel includes two hard keys;
a first hard key of the second bezel is used for entrance into an editing mode in which a chronograph displayed on the display unit is able to be edited; and
a second hard key of the second bezel is used for access to applications installed in the mobile terminal.

4. The operating method of claim 1 , wherein, when the bezel is recognized as a fourth bezel including five hard keys, one of the five hard keys is used to display a plurality of sports items, and remaining four keys among the five hard keys are used to provide information related to a sports item selected from among the plurality of sports items.

5. A wearable mobile terminal comprising:
a main body including a display unit;
a band coupled to the main body;
a bezel detachable from the display unit; and
a control unit configured to:
recognize the bezel attached to the display unit as at least a first bezel, a second bezel, or a third bezel based on at least one of a number of hard keys included in the bezel, positions of the hard keys on the bezel, a material of the bezel, or a color of the bezel;
perform a first function in response to a first input received via at least one hard key of the recognized first bezel; and
perform a second function in response to a second input received via at least one hard key of the recognized second bezel;

wherein the recognized third bezel includes three hard keys, and the control unit is further configured to cause the display unit to:
display a menu screen in response to a third input received via a first hard key of the third bezel;
display a home screen in response to a fourth input received via a second hard key of the third bezel; and
display a previous screen in response to a fifth input received via a third hard key of the third bezel.

6. The mobile terminal of claim 5 , wherein:
the first bezel includes one hard key; and
the control unit turns on or off power of the mobile terminal, displays the home screen or the menu screen, or displays a setting screen when the first function is performed.

7. The mobile terminal of claim 5 , wherein:
the second bezel includes two hard keys;
a first hard key of the second bezel is used for entrance into an editing mode in which a chronograph displayed on the display unit is able to be edited; and
a second hard key of the second bezel is used for access to applications installed in the mobile terminal.

8. The mobile terminal of claim 5 , wherein, when the bezel is a fourth bezel including five hard keys, one of the five hard keys is used to display a plurality of sports items, and remaining four keys among the five hard keys are used to provide information related to a sports item selected from among the plurality of sports items.

9. The mobile terminal of claim 5 , further comprising a sensing unit to acquire information on the bezel attached to the display unit,
wherein the control unit recognizes the type of the bezel by using one of an electrical capacitance and a metal code of the attached bezel, which are sensed through the sensing unit.
