Abstract

PURPOSE:To enable a user to perform the intuitive input and editing operation without taking the subtle deviation of the shape and the position of input into consideration by discriminating the input mode based on the state of a mode switching means provided with a handwritten character input device. CONSTITUTION:A switch 61 accessory to a pen is the input mode switching means, and gestures are inputted in the case of input with the switch on, and characters, graphics, and images are inputted in the case of input with the switch off. An input mode discriminating part 1121 discriminates the character, graphic, and image input or the gesture input based on the state of the input mode switching means of the hand-written character input device. A recognition processing part 1122 performs the recognition processing adapted to the result of discrimination and sends the recognition result to a window control part 111. Since the user sets the input mode by the switching means of the handwritten character input device in this case, the recognition result in the objective mode is always obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handwritten character input device in an information processing device using online handwritten character recognition.

[0002]

2. Description of the Related Art In an online handwritten character recognition apparatus, in addition to characters, figures and images, input of editing symbols (hereinafter referred to as gestures), which incorporates proofreading symbols commonly used in the US publishing world, Recognition is supported. The user can specify the edit target and execute the edit command with a single gesture input.

The user inputs characters, figures, images and gestures in the handwriting input mode, and the system
It is determined whether a figure, an image, or a gesture is input. The determination process is performed based on the input shape of the user and the position on the screen. The edit symbol has a predetermined shape and is determined as an edit symbol by being input on the application data (characters, figures, images), and input in the area without data is the input of letters, figures, images. Is determined. If the result of the determination is that a character, figure, or image is input, the recognition result is displayed on the screen, and if a gesture is input, appropriate editing processing is performed.

[0004]

SUMMARY OF THE INVENTION In the above prior art,
When inputting an image similar to a gesture, the system may determine that the gesture is against the user's intention. On the other hand, even if a gesture is intentionally input, it may be displayed on the screen as an image of a similar shape. There are two possible causes for this.
The first point is that the input shape is erroneously recognized, and the second point is that it was not possible to input different areas depending on the purpose, into the area where the system determined to input characters, figures, and images and the area where determination was made as gesture input. It is an input error by the user. In order to obtain the intended recognition result, it is necessary to give careful consideration to the shape and position of the input, which hinders intuitive operation. Further, if the input fails and the responses of the information processing devices against the intention overlap, the stress on the user increases.

It is an object of the present invention, when a user starts handwriting input, without considering a slight deviation between the shape and position of the input which is the basis of the input mode judgment by the system,
The purpose is to enable intuitive input and editing operations.

[0006]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a means for switching between a character input mode, a graphic input mode, an image input mode (hereinafter, abbreviated as character input mode) and a gesture input mode. The input mode is determined based on the state of the mode switching means in the device.

[0007]

When the user sets the mode to either the character input mode or the gesture input mode by the mode switching means of the handwritten character input device and starts the input, the input mode determination unit of the recognition module causes the input mode determination unit of the recognition module to operate. The input mode is determined based on the state.

Since the input mode can be set by a simple operation at the start of handwriting input, the operability is not impaired.
It is possible to input or edit as intended.
