## Abstract

In one embodiment, an interface navigation system including a display unit and a control unit that is coupled to the display unit is described. The control unit is configured to detect a first movement of an interface navigation control input in a particular direction, and cause a corresponding second movement and a corresponding change in shape of a visual effect displayed on the display unit in response to the first movement in the particular direction.

## Claims

### Claim 1

A television (TV) to provide visual feedback on control movements detected by a remote control unit, comprising:
a display unit of the TV; and
a processor, coupled to the display unit, configured to control the display unit to display:
a plurality of graphical user interface (GUI) objects on the display unit of the TV; and
a visual effect applied to a GUI object selected from among the plurality of GUI objects to represent in part navigational control input from a user, wherein the visual effect comprises two layers including:
an outer layer that visually encompasses the GUI object along at least a portion of an outer edge of a contour of the GUI object, and
an inner layer that is visually enclosed within the GUI object and takes a same shape as the GUI object and is along an inner edge of the contour of the GUI object;
the processor further configured to:
when there is no user input detected, display the outer layer of the visual effect;
in response to a user touch detected on the remote control unit, enlarge a size of a portion of the outer layer of the visual effect while the inner layer maintains the same shape as the GUI object; and
in response to a touch drag detected following the user touch on the remote control unit:
deform a shape and change a positon of the portion of the outer layer of the visual effect to indicate a direction of the touch drag, and
change the size of the portion of the outer layer of the visual effect such that the size of the portion of the outer layer becomes smaller as the position of the portion of the outer layer moves closer to a corner of the GUI object while the inner layer maintains the same shape as the GUI object.

### Claim 2 (depends on 1)

The device of claim 1, wherein when the portion of the outer layer of the visual effect reaches a corner of the GUI object and a distance of the touch drag is greater than a threshold value, then the outer layer of the visual effect and the inner layer of the visual effect are applied to another one of the plurality of GUI objects.

### Claim 3 (depends on 1)

The device of claim 1, wherein
the outer layer has a glowing effect, and
the inner layer is shaded darker than the outer layer having the glowing effect.

### Claim 4 (depends on 1)

The device of claim 1, wherein in response to the user touch on the remote control unit, the size of the portion of the outer layer of the visual effect is enlarged but a size of the GUI object is not enlarged.

### Claim 5 (depends on 1)

The device of claim 1, wherein in response to a release of the user touch from the remote control unit, the size of the portion of the outer layer of the visual effect is no longer enlarged.

### Claim 6 (depends on 1)

The device of claim 1, wherein the outer layer of the visual effect visually encompasses the GUI object along the entire outer edge of the contour of the GUI object, and wherein in response to the touch drag following the user touch on the remote control unit, the shape of the portion of the outer layer is deformed to indicate the direction of the touch drag while the outer layer of the visual effect visually encompasses the GUI object along the entire outer edge of the contour of the GUI object.
