Remote control method and apparatus thereof
First Claim
1. A remote control method for performing a remote control operation of an image apparatus by using a remote controller having a touch panel and a contact means, said method comprising the steps of:
- selecting one of a character and a cursor as a function control input means for selecting a function of the image apparatus;
sensing a location of a contact point of the contact means on the touch panel if the cursor is selected in the selecting step;
digitizing the location on the touch panel of the sensed contact point;
generating a signal corresponding to the digitized location of the contact point and transmitting the generated signal to the image apparatus;
positioning the cursor displayed on the image apparatus at a location corresponding to the sensed location of the contact point of the contact means on the touch panel;
selecting a function displayed on the image apparatus according to the location of the cursor;
tracing a character onto the touch panel with the contact means if the character is selected in said step of selecting one of a character and a cursor as a function control input means;
sensing said character traced onto the touch panel in said tracing step;
digitizing the sensed character; and
generating a signal corresponding to the digitized character and transmitting the generated signal to the image apparatus in order to perform a function corresponding to the sensed character.

Abstract
A remote control method and apparatus for a remote controller having a touch panel as an input device, performs a remote control operation of an image apparatus, such as a television, either by inputting a character onto the touch panel or by controlling a cursor according to the contact location of a finger or a pen contacting the touch panel. The input character or contacting the touch panel to control a cursor, are used to select a function shown on a menu screen displayed on the image apparatus. The selection is made according to the movement of the cursor, causing the image apparatus to perform the function corresponding to either the character input onto the touch panel or the function selected by the cursor. The result of employing a touch screen is to reduce the number of keys of the remote controller and, thus, perform the desired function more easily.

9. A remote controller for remotely controlling an image apparatus according to a remote control signal, said remote controller comprising:
-
a touch panel; a touch sensor for sensing one of a contact point and a character traced onto said touch panel with a contact means and outputting a sensing signal; a scan converter for converting the sensing signal into a digital data form; a key input device having at least a character/cursor selection key for indicating a selection of one of a cursor mode and a character mode; a processor for determining said character traced onto said touch panel, recognizing an output signal of said scan converter and a key signal of said key input device and outputting a drive signal according to the recognition result; and a transmitter for generating said remote control signal according to the drive signal output from said processor, and transmitting the remote control signal to said image apparatus. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
