Abstract

An electronic device includes a handwriting pen and a main body. A gyroscope senses movement information of the handwriting pen and outputs the movement information to a controller. The controller converts the movement information into electrical signals and outputs the electrical signals to the main body through a signal transmitting module. A processor receives the electrical signals through a signal receiving module and the signal transmitting module, converts the electrical signals into movement information, and outputs the movement information to a character identification module. The character identification module converts the movement information into a corresponding character, and controls the display unit to display the character.

Claims

1. An electronic device, comprising:

a handwriting pen comprising;

a wireless signal transmitting module;

a gyroscope to sense movement information of the handwriting pen and output the movement information; and

a controller to receive the movement information from the gyroscope, convert the movement information into electrical signals, and output the electrical signals through the signal transmitting module; and

a main body comprising;

a display unit;

a wireless signal receiving module;

a processor to receive the electrical signals from the handwriting pen through the signal receiving module and the signal transmitting module, convert the electrical signals into movement information, and output the movement information; and

a character identification module to receive the movement information from the processor, convert the movement information into a corresponding character, and control the display unit to display the character.
