Abstract

An interfacing apparatus may sense an input object and move at least one interface object displayed on a display toward the sensed input object.

Claims

1. An interfacing apparatus, comprising:

a display configured to display interface objects;

a sensor configured to sense an input object; and

one or more processors configured to;

calculate, based on a position of a tip area, an interface area of the input object, and

move the interface objects in different directions to an inside of the interface area of the input object, wherein a display sequence of the interface objects in an x and y coordinate system is maintained, and

wherein the interface area comprises an adjacent area of the tip area within a predetermined radius from the tip area, the tip area is a projection of at least a portion of the input object disposed at a distance above the display and projected to the display, and the adjacent area is an area reachable by the input object.

2. The interfacing apparatus of claim 1, wherein:

the sensor is configured to measure a proximity between the input object and a reference surface of the interfacing apparatus; and

the one or more processors are configured to move the interface objects inside the interface area of the input object in response to the proximity being less than a predetermined distance.

3. The interfacing apparatus of claim 1, further comprising:

a signal processor configured to extract a position of a portion of the input object,

wherein the portion of the input object comprises the tip area, and the one or more processors are configured to calculate the interface area of the input object based on the extracted position of the portion of the input object.

4. The interfacing apparatus of claim 3, wherein the portion of the input object comprises at least one of:

a tip area of the input object; and

an intersection area between the input object and a boundary of the display.

5. The interfacing apparatus of claim 1, wherein the one or more processors are configured to:

extract an interface object controllable by the input object from the interface objects; and

move the extracted interface object to the inside of the interface area of the input object.

6. The interfacing apparatus of claim 1, wherein

the one or more processors are configured to move the interface objects to the inside of the interface area of the input object while maintaining a sequence determined based on an x-coordinate of the interface objects.

7. The interfacing apparatus of claim 1, wherein the one or more processors are configured to move the interface objects to the inside of the interface area of the input object while maintaining a sequence determined based on a y-coordinate of the interface objects.

8. The interfacing apparatus of claim 1, wherein the one or more processors are configured to move the interface objects to the inside of the interface area of the input object while maintaining a sequence determined based on a combination of an x-coordinate and a y-coordinate of the interface objects.

9. The interfacing apparatus of claim 1, wherein:

the sensor is configured to sense whether the input object is in contact with a reference surface of the interfacing apparatus; and

the one or more processors are configured to select an interface object corresponding to a location at which the input object is in contact with the reference surface.

10. The interfacing apparatus of claim 1, wherein:

the at least one interface object comprises a first interface object and a second interface object; and

the one or more processors are further configured to;

move the first interface object in a first direction to an inside of the interface area of the input object, and

move the second interface object in a second direction to an inside of the interface area of the input object,

wherein a display sequence of the first interface object and the second interface object is maintained.

11. The interfacing apparatus of claim 1, wherein:

the at least one interface object comprises a first interface object and a second interface object; and

the one or more processors are further configured to;

move the first interface object a first distance to an inside of the interface area of the input object, and

move the second interface object a second distance to an inside of the interface area of the input object,

wherein x-coordinate positions of the first interface object and the second interface object or y-coordinate positions of the first interface object and the second interface object are maintained.

12. An interfacing method, comprising:

displaying interface objects on a display;

sensing an input object;

calculating, based on a position of a tip area, an interface area of the input object, and moving the interface objects in different directions to an inside of the interface area of the input object, wherein a display sequence of the interface objects in an x and y coordinate system is maintained,

wherein the interface area comprises an adjacent area of the tip area within a predetermined radius from the tip area, the tip area is a projection of at least a portion of the input object disposed at a distance above the display and projected to the display, and the adjacent area is an area reachable by the input object.

13. The interfacing method of claim 12, wherein:

the sensing comprises measuring a proximity between the input object and a reference surface of an interfacing apparatus; and

the moving comprises moving the interface objects to the inside of the interface area of the input object in response to the proximity being less than a predetermined distance.

14. The interfacing method of claim 12, further comprising:
