## Abstract

A method of controlling a watch-type mobile terminal having a touch bezel includes performing communication with an external device via a wireless communication unit; executing a first contact application stored in a memory; displaying a contact list on a display unit while executing the first contact application; sensing a drag touch input on the display unit while executing the first contact application; scrolling the contact list in response to sensing the drag touch input on the display unit while executing the first contact application; sensing a rotation touch input on a touch bezel located on an edge of the watch-type mobile terminal while executing the first contact application, wherein a direction of the drag touch input is different from a direction of the rotation touch input; displaying a quick scroll pop-up screen on the display unit when a speed of the rotation touch input on the touch bezel located on the edge of the watch-type mobile terminal is faster than a predetermined speed while executing the first contact application; and displaying a different screen on the display unit that is different than a screen where the quick scroll pop-up screen is displayed when a speed of the rotation input on the touch bezel located on the edge of the watch-type mobile terminal is slower than the predetermined speed while executing the first contact application.

## Claims

### Claim 1

A method of controlling a watch-type mobile terminal having a touch sensitive bezel, the method comprising:
performing communication with an external device via a wireless communication unit;
executing a first contact application stored in a memory;
displaying a first set of contacts of a contact list on a display while executing the first contact application;
sensing a touch input on one of the display or the touch sensitive bezel, while executing the first contact application;
in response to the touch input being a rotational drag touch input on the touch sensitive bezel at a first moving speed greater than a predetermined speed, displaying a quick scroll pop-up screen with a portion of the contact list;
in response to the touch input being a non-rotational drag touch input along a vertical direction, scrolling the contact list according to a first manner, wherein the first manner scrolls the contact list without displaying the quick scroll pop-up screen; and
in response to the touch input being a rotational drag touch input on the touch sensitive bezel at a second moving speed less than the predetermined speed, scrolling the contact list according to the first manner without displaying the quick scroll pop-up screen,
wherein the touch sensitive bezel surrounds the contact list displayed on the display,
wherein the displaying the quick scroll pop-up screen with the contact list includes:
displaying a plurality of circle icons, where each of the plurality of circle icons includes a single text character for the quick scroll pop-up screen, each of the plurality of circle icons is arranged in a list in a center of the display while one or more contacts from the contact list are also displayed, each of one or more contacts including a text string corresponding to a name and a circular image disposed to the left of the text string, and
wherein the circular image disposed to the left of the text string is displayed without overlapping with the plurality of circle icons of the quick scroll pop-up screen.

### Claim 2 (depends on 1)

The method of claim 1, wherein the watch-type mobile terminal is connected to the external device via Bluetooth, and the touch sensitive bezel has a ring shape.

### Claim 3 (depends on 1)

The method of claim 1, wherein the second set of contacts of the contact list include favorite contacts of the contact list.

### Claim 4 (depends on 1)

The method of claim 1, wherein the rotational drag touch input includes a random starting position on the touch sensitive bezel.

### Claim 5 (depends on 1)

The method of claim 1, wherein the circular image disposed to the left of the text string includes an image of a person.

### Claim 6 (depends on 1)

The method of claim 1, wherein the quick scroll pop-up screen includes a plurality of icons.

### Claim 7

A watch-type mobile terminal having a touch sensitive bezel, the watch-type mobile terminal comprising:
a wireless communication unit configured to perform communication with an external device;
a memory configured to store a first contact application;
a display configured to display a contact list; and
a controller configured to:
cause the display to display a first set of contacts of the contact list,
sense a touch input on one of the display or the touch sensitive bezel,
in response to the touch input being a rotational drag touch input on the touch sensitive bezel at a first moving speed greater than a predetermined speed, cause the display to display a quick scroll pop-up screen with a portion of the contact list,
in response to the touch input being a non-rotational drag touch input along a vertical direction, scroll the contact list according to a first manner, wherein the first manner scrolls the contact list without displaying the quick scroll pop-up screen, and
in response to the touch input being a rotational drag touch input on the touch sensitive bezel at a second moving speed less than the predetermined speed, scroll the contact list according to the first manner without displaying the quick scroll pop-up screen,
wherein the touch sensitive bezel surrounds the contact list displayed on the display,
wherein the quick scroll pop-up screen with the contact list includes:
a plurality of circle icons, where each of the plurality of circle icons includes a single text character for the quick scroll pop-up screen, each of the plurality of circle icons is arranged in a list in a center of the display while one or more contacts from the contact list are also displayed, each of one or more contacts including a text string corresponding to a name and a circular image disposed to the left of the text string, and
wherein the circular image disposed to the left of the text string is displayed without overlapping with the plurality of circle icons of the quick scroll pop-up screen.

### Claim 8 (depends on 7)

The watch-type mobile terminal of claim 7, wherein the watch-type mobile terminal is connected to the external device via Bluetooth, and the touch sensitive bezel has a ring shape.

### Claim 9 (depends on 7)

The watch-type mobile terminal of claim 7, wherein the second set of contacts of the contact list include favorite contacts of the contact list.

### Claim 10 (depends on 7)

The watch-type mobile terminal of claim 7, wherein the rotational drag touch input includes a random starting position on the touch sensitive bezel.

### Claim 11 (depends on 7)

The watch-type mobile terminal of claim 7, wherein the circular image disposed to the left of the text string includes an image of a person.

### Claim 12 (depends on 7)

The watch-type mobile terminal of claim 7, wherein the quick scroll pop-up screen includes a plurality of icons.
