Pen type input device and method for character input and mouse functions

1. A pen-type input device for performing input to a host device, comprising:

a first switch located on an end of a pen tip, configured to generate a first signal used for click inputting a character stroke in a character input mode and moving a mouse cursor in a mouse mode; and

a second switch configured generate a second signal used for performing a mouse click operation in the mouse mode,

wherein the host device:

executes a web browsing application and displays an execution screen for the web browsing application comprising a text input window;

while the web browsing application is executed, moves the mouse cursor according the first signal or maintains a location of the mouse cursor, based on whether the first signal is detected in the mouse mode;

changes an input mode of the host device from the mouse mode to the character input mode, in response to detecting the second signal when the mouse cursor is disposed in the text input window;

displays a character stroke according to the first signal or moves the location of the mouse cursor, based on whether the first signal is detected in the character input mode; and

changes at least one of color, size and shape of the character by using the second signal.

2. The pen-type input device of claim 1 , further comprising a transmitter for transmitting location information of the pen-type input device and at least one of the first signal and the second signal, to the host device.

3. The pen-type input device of claim 2 , wherein the transmitter transmits the location information of the pen and at least one of the first signal and the second signal to the host device using at least one of Bluetooth and ZigBee short-range wireless communication.

4. A method for performing input in a host device using a pen-type input device, comprising:

executing a web browsing application and displaying an execution screen for the web browsing application comprising a text input window;

determining an input mode as a mouse mode when the web browsing application is executed;

receiving location information of the pen-type input device from the pen-type input device;

receiving a first signal used for click inputting a character stroke in a character input mode and moving a mouse cursor in the mouse mode from the pen-type input device;

receiving a second signal used for performing a mouse click operation in the mouse mode from the pen-type input device;

moving the mouse cursor according to the first signal and the location information or maintaining a location of the mouse cursor, based on whether the first signal is detected in the mouse mode;

changing an input mode of the host device from the mouse mode to the character input mode, in response to detecting the second signal when the mouse cursor is disposed in the text input window;

displaying a character stroke according to the location information and the first signal or moving the location of the mouse cursor, based on whether the first signal is detected in the character input mode; and

changing at least one of color, size and shape of the character by using the second signal.

5. The method of claim 4 , wherein the input mode is automatically set according to a type of application executed in the host device.

6. The method of claim 4 , wherein the input mode is automatically set to the character input mode when the text input window for character input is activated in the host device.

7. The method of claim 4 , wherein the mouse click operation comprises at least one of a language switching operation and a special character input operation.

8. The method of claim 4 , wherein the location information and the at least one of the first signal and the second signal are received using at least one of Bluetooth and ZigBee short-range wireless communication.

9. A host device comprising:

a display;

a receiver; and

a controller configured to:

execute a web browsing application and display, on the display, an execution screen for the web browsing application comprising a text input window;

determine an input mode as a mouse mode when the web browsing application is executed;

receive, through the receiver, location information of a pen-type input device, a first signal used for click inputting a character stroke in a character input mode and moving a mouse cursor in the mouse mode, and a second signal used for performing a mouse click operation in the mouse mode;

move the mouse cursor according to the first signal and the location information or maintain a location of the mouse cursor, based on whether the first signal is detected in the mouse mode;

change the input mode of the host device from the mouse mode to the character input mode, in response to detecting the second signal when the mouse cursor is disposed in the text input window;

display the character stroke according to the location information and the first signal or move the location of the mouse cursor, based on whether the first signal is detected in the character input mode; and

change at least one of color, size and shape of the character by using the second signal.

10. The host device of claim 9 , wherein the input mode is automatically set according to a type of application executed in the host device.

11. The host device of claim 9 , wherein the input mode is automatically set to the character input mode when the text input window for character input is activated in the host device.

12. The host device of claim 9 , wherein the mouse click operation comprises at least one of a language switching operation and a special character input operation.

13. The host device of claim 9 , wherein the receiver receives the location information and the at least one of the first signal and the second signal using at least one of Bluetooth and ZigBee short-range wireless communication.

14. A method for controlling a pen-type input device for performing input to a host device, comprising:

generating a first signal used for click inputting a character stroke in a character input mode and moving a mouse cursor in a mouse mode; and

generating a second signal used for performing a mouse click operation in the mouse mode,

wherein the host device:

executes a web browsing application and displays an execution screen for the web browsing application comprising a text input window;

while the web browsing application is executed, moves the mouse cursor according to the first signal or maintains a location of the mouse cursor, based on whether the first signal is detected in the mouse;

changes an input mode of the host device from the mouse mode to the character input mode, in response to detecting the second signal when the mouse cursor is disposed in the text input window;

displays a character stroke according to the first signal or moves the location of the mouse cursor, based on whether the first signal is detected in the character input mode; and

changes at least one of color, size and shape of the character by using the second signal.

15. The method of claim 14 , further comprising transmitting location information of the pen-type input device to the host device.

16. The method of claim 15 , wherein the location information of the pen-type input device and at least one of the first signal and the second signal are transmitted to the host device using at least one of Bluetooth and ZigBee short-range wireless communication.
