Writing Image Input Device

The present invention relates to a handwriting image input apparatus, and more particularly, to an interactive apparatus having a function of inputting information in a form in which characters, figures, and the like are written.

An interactive device operating in a manner of exchanging information with a user has a user input means for the user to input information. The interactive device may include a computer, a communication device such as a mobile communication terminal, and a multimedia device such as a personal digital assistant (PDA).

As one of the user input means constituting the interactive device, a touch screen for inputting information by a contact operation is conceived and used.

An interactive device having a touch screen operates in the following manner.

First, the user touches a hand or an object to the touch screen.

When a hand or an object touches the touch screen, an electromagnetic contact signal corresponding to each touch action is generated. Here, the principle of generating the contact signal includes a capacitance method, a resistive film method, a surface ultrasonic method, an infrared method, and the like.

Next, the coordinate value of the contact position is calculated based on the generated contact signal.

Finally, the interactive apparatus executes an operation (command execution, cursor movement, etc.) corresponding to the calculated coordinate value according to a predetermined program.

Recently, a method of inputting information of a character, a figure, etc. using a touch screen as it is written (except when reading the written character and converting it into a machine-readable character is excluded) is proposed. It is used. Hereinafter, the information as it is written is called a handwriting image, and an interactive device having a function of inputting a handwriting image through a touch screen is called a handwriting image input device. In addition, the handwriting image device may include a multimedia content playing function, a camera function, a web surfing function, and the like in addition to a function of inputting a handwriting image.
