Abstract

Disclosed are a glass type terminal capable of supporting gestures using one finger or two fingers by providing a three-dimensional input device at a temple hinged to a rim of a lens, and an input method thereof. For three-dimensional touch inputs, the temple is configured to have an upper surface, a lower surface, an inner side surface and an outer side surface provided touch sensor, respectively. Upon sensing of a touch input applied onto said one or more surfaces of the temple using one finger or two fingers, a screen displayed on a lens is controlled in correspondence to the sensed touch input. Under such configuration, a user can control the screen in a more convenient manner.

5. The terminal of claim 1,

wherein the at least two different sides includes at least two of an upper side, a lower side, or an outer side of the arm relative to the user when the terminal is worn on the head of the user, and

wherein the controller is configured to control the screen based on touches detected on the at least two of the upper side, the lower side, or the outer side of the arm.

6. The terminal of claim 1,

wherein the touch sensor located includes transmit electrodes arranged in a lengthwise direction of the arm, and receive electrodes arranged in a widthwise direction of the arm, and

wherein a relatively smaller number of transmit electrodes arranged in the lengthwise direction are located on an inner side of the arm than are located on another side of the plurality of sides.

7. The terminal of claim 6, wherein a bundle of the receive electrodes are arranged on the inner side of the arm, and a bundle of the transmit electrodes are arranged at an inner corner region on the outer side of the arm.

8. The terminal of claim 1, further comprising:

a camera operatively connected to the controller and configured to capture a still or moving picture; and

a movement sensor operatively connected to the controller and configured to sense a movement of the user'"'"'s head,

wherein the controller is configured to;

enter a still or moving picture capture mode upon sensing that the user touches each of the at least two different sides for a predetermined time;

enlarge or contract a preview image of an object to be captured by the camera upon sensing that the user simultaneously moves the touches to each of the at least two different sides in opposite directions;

focus the object to be captured according to a sensed moving direction of the user'"'"'s head while touching each of the at least two different sides; and

capture the object upon sensing that the user removes the touches from each of the at least two different sides.

9. The terminal of claim 1, wherein the controller is configured to

display a main menu on an upper region of the screen upon sensing that a touch on a first side of the at least two different sides is moved along the first side,

display a sub menu on the screen upon sensing that a touch on a second side of the at least two different sides is moved along the second side, and

display both of the main menu and the sub menu on the screen upon sensing that touches to the first and second sides are simultaneously moved in opposite directions the along the first and second sides, respectively.

10. The terminal of claim 9, wherein the controller is configured to integrate a function of the main menu and a function of the sub menu upon sensing a movement of the touches to the first and second sides to a third side of the at least two different sides.

11. The terminal of claim 1, wherein the controller is configured to display a gesture guide on the screen upon sensing that the terminal is placed on the user'"'"'s head initially or after a predetermined period of non-use, or upon sensing that the arm is lifted up and moved down via touches to the at least two different sides.

12. The terminal of claim 1, wherein the controller is configured to

display a first menu on an upper region of the screen upon sensing a touch on a first side of the at least two different sides,
