Abstract

A display apparatus is disclosed. The display apparatus includes a display, an input unit configured to receive a handwriting trace, in response to a user handwriting being performed at a remote control apparatus; a detector configured to determine text corresponding to the handwriting trace; and a controller configured to search for an item corresponding to the text, classify the item into a plurality of categories, and control the display to display the item on the display.

Claims

1. A display apparatus comprising:

a display;

an input unit configured to receive a handwriting trace, in response to a user handwriting being performed at a remote control apparatus;

a detector configured to determine text corresponding to the handwriting trace; and

a controller configured to search for an item corresponding to the text, classify the item into a plurality of categories, and control the display to display the item on the display.

2. The apparatus as claimed in claim 1, wherein the controller is further configured to, in response to a subsequent handwriting being performed at the remote control apparatus, determine a subsequent text from a subsequent handwriting trace according to the subsequent handwriting, search for an item corresponding to the text and the subsequent text, classify the item corresponding to the text and the subsequent text according to the plurality of categories, and control the display to the item corresponding to the text and the subsequent text.

3. The apparatus as claimed in claim 1, wherein the controller is further configured to control the display to display a handwriting display area indicating the received handwriting trace on an area of a screen, match each of the plurality of categories in up, down, left, and right directions extending from the handwriting display area, and control the display to arrange and display a search result classified by the plurality of categories.

4. The apparatus as claimed in claim 3, wherein the controller is further configured to control the display to display the handwriting display area at a center of the screen or at one of four corners on the screen.

5. The apparatus as claimed in claim 1, wherein the controller is further configured to, in response to the item being selected, perform a control operation corresponding to the selected item.

6. The apparatus as claimed in claim 1, wherein the plurality of categories include at least one of an application category, a web category, a function category, and a content category.

7. A display method comprising:

receiving a handwriting trace in response to a user handwriting being performed at a remote control apparatus;

determining text from the handwriting trace;

searching an item corresponding to the text; and

classifying the item into a plurality of categories and displaying the item and at least one of the plurality of categories on a display.

8. The method as claimed in claim 7, further comprising:

in response to a subsequent handwriting being performed at the remote control apparatus, determining a subsequent text from a subsequent handwriting trace according to the subsequent handwriting;

searching for an item corresponding to the text and the subsequent text; and

classifying the item corresponding to the text and the subsequent text according to the plurality of categories; and

displaying the item corresponding to the text and the subsequent text on the display.

9. The method as claimed in claim 7, further comprising:

displaying a handwriting display area indicating the received handwriting trace on an area of a screen;

matching each of the plurality of categories in up, down, left, and right directions extending from the handwriting display area; and

arranging and displaying a search result classified by the plurality of categories.

10. The method as claimed in claim 9, wherein the handwriting display area is displayed at the center of the screen or at one of four corners on the screen.

11. The method as claimed in claim 7 further comprising:

in response to the item being selected, performing a control operation corresponding to the selected item.

12. The method as claimed in claim 7, wherein the plurality of categories include at least one of an application category, a web category, a function category, and a content category.

13. A display system comprising;

a display configured to display handwriting based content, the display comprising;

a receiver configured to receive a handwriting trace;

a controller configured to control analysis of the handwriting trace, extraction of input data from the handwriting trace, and displaying of the handwriting based content based on the input data; and

a remote controller configured to receive a user handwriting, the remote controller comprising;

a touch screen configured to receive the user handwriting that corresponds to the input data;

a controller configured to generate the handwriting trace based on the user handwriting; and

a transmitter configured to transmit the handwriting trace.

14. A method for displaying a user handwriting, the method comprising:

receiving, through a touch screen of a remote controller, a user handwriting that corresponds to input data;

generating, at the remote controller, a handwriting trace based on the user handwriting and transmitting the handwriting trace;

receiving, at a display, the handwriting trace;

determining, at a display, the input data from the handwriting trace; and

displaying, at a display, handwriting based content based on the input data.
