Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing device,
In particular, it relates to the input of commands that determine its execution function.

[0002]

2. Description of the Related Art In an information processing apparatus, when a command is input, conventionally, a menu is displayed on a display screen,
A menu selection method in which a command is input by instructing one of the displayed commands with an input device such as a mouse is widely adopted.

[0003]

However, when making a menu selection, when grasping the mouse with the hand and moving it to the desired menu item while keeping it in contact with the desk and confirming the instruction item, the attached The operability was poor because it was necessary to operate the button SW. In particular, since the menu generally has a hierarchical structure, it is necessary to repeat the above-mentioned operations, and it cannot be said that the menu is always convenient.

The present invention employs a command input method with good operability, which enables menu-corresponding processing by enabling handwritten command input by using a pen coordinate input device without depending on menu selection by a mouse. To provide the information processing device.

[0005]

In order to achieve the above object, a command input method according to the present invention employs a pen coordinate input device, and the pen coordinate input device enables designation of a menu selection type command. At the same time, a command can be designated by a handwriting input pattern using the pen coordinate input device, and both command designations can be selectively used.

Further, the information processing apparatus according to the present invention is a command selecting means of menu selection method, a handwriting command input means, and a command analysis for judging what command is inputted by both command input means. Means and an executing means for executing the command determined by the command analyzing means, wherein both the command input means are
The commands are input by the same pen coordinate input device.

[0007]

The operation of the typical structure of the present invention will be described below.

When the execution menu is selected by the menu-based command input means, the input command is analyzed by the command analysis means and the result is transmitted to the command execution means, where the corresponding processing is executed. Further, when the execution menu is selected from the menu-based command input means, if there is a handwriting command registration request, the handwriting command input means receives the handwriting input pattern to be registered, and the handwriting command registration storage is performed. Store this in the means. After that, if there is an input directly from the handwriting command input means instead of from the menu type command input means, this is transmitted to the command analysis means, and here, the handwriting commands already registered in the handwriting command registration storage means. And the result is transmitted to the command executing means. The command execution means executes the processing of the command.

According to the present invention, the operability of function selection is improved by using the handwriting command together with the command selection by the menu. In the case of menu selection, in order to select a command that belongs to the lower layer of the hierarchy, it is necessary to select from the upper layer to the lower layer in order, but once you register handwritten commands, you can directly specify the command. It becomes possible to do it.

Further, since the pen coordinate input device is also used for selecting the menu, the mouse conventionally used for selecting the menu becomes unnecessary, and a single input device can be used to specify both the menu selection and the handwriting command. Is available. Therefore, it is possible to select a command designating method according to the application or the operator's preference, and the usability is improved.
