Description

  The present invention relates to a handwritten information input display system, and more particularly, to a handwritten information input display device including a display unit that displays an input image and a menu image, and a touch pen that performs a handwriting input operation and a menu operation on the handwritten information input display device. The present invention relates to a handwritten information input display system.

  In recent years, various display terminal devices capable of direct handwriting input using a coordinate input device such as a touch pen on a GUI screen, such as a tablet PC and a PDA, have been studied. This display terminal device is used by inputting and storing graphics such as characters and illustrations by handwriting on a character screen or a blank screen.

  When performing handwriting input, it is necessary to change the thickness and color of the line, and to select an editing command for the handwriting input application such as page turning and scrolling. Such an operation is realized by displaying a menu screen on the display screen and tapping the menu screen using a touch pen or the like.

  Normally, the menu screen or the button for calling the menu screen is always displayed at the end of the display screen and is arranged so as not to overlap the handwriting input area. However, since the menu screen is displayed, the handwriting input area is narrowed, and it is necessary to perform troublesome operations such as moving the touch pen to the end of the display screen one by one when performing menu operations.

Therefore, in order to cope with such a problem, that is, the menu screen is made translucent so that a hidden screen display can be seen behind the menu screen and the menu operation can be easily performed at hand. Then, it is determined based on a predetermined determination criterion whether the operation being performed is a handwriting input operation or a menu operation, and a process corresponding to each is executed based on the determination result, so that the desired operation can be reliably performed. Have been proposed (see, for example, Patent Document 1 and Patent Document 2).

  With regard to a method for determining whether the operation being performed is a handwriting input operation or a menu operation, the handwriting information input device described in Patent Document 1 determines which operation is performed by the handwriting input detection unit based on the stroke of the handwriting input. It is configured. Moreover, in the apparatus which provides the virtual graffiti described in Patent Document 2, the control unit determines which operation is performed based on the touch position and / or touch method.

  However, in any case, there is a problem that the operation intended by the user is difficult to be reflected. For example, when “•” is input, it is difficult to determine whether “•” is a handwriting input operation or “•” is a menu selection operation.

  The present invention has been made in view of the above problems, and includes a handwritten information input display device including a display unit that displays an input image and a menu image, and a touch pen that performs a handwriting input operation and a menu operation on the handwritten information input display device.
