Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention converts a data operation history by a user into a form that can be displayed, edited, and reused on a computer system capable of interactive data operation, and can be used by the user. The present invention relates to a visualizing device for presenting operation sequences.

[0002]

2. Description of the Related Art A conventional method converts an operation sequence of data into a text format programming language. The operation performed by the user using the keyboard or the mouse is converted into a command of a programming language, and the result is presented to the user in an editable form.

[0003]

When a user interactively operates data, a mouse, which is a pointing device, is mainly used. In the conventional method, since the operation sequence is converted into text, the keyboard is mainly used for the editing work. For this reason, there is a problem in that the device used when operating the data is different from the device used when editing the operation sequence, which increases the burden on the user.

In the text-type programming language, the time course of the operation is expressed in one dimension. Therefore, if the user cancels the operation, 1. The canceled operation is not displayed. The description that the operation was canceled was either displayed in the same row as the regular operation. In the former case, there was a problem that the operation history that was canceled cannot be reused. In the latter case, the legitimate operation and the canceled operation are displayed in the same row, which reduces the readability of the program and makes reuse difficult.

[0005]

According to the operation sequence visualization operation of the present invention, an operation interpretation unit for converting an operation performed by a user into a command and a command converted by the operation interpretation unit are stored as an operation sequence. An operation sequence storage unit, an operation sequence conversion unit that converts the operation sequence into an effective graph, an operation sequence display unit that displays the effective graph in an editable form, and re-executes the operation sequence based on the effective graph. And an operation sequence execution unit for performing

Further, the effective graph is characterized in that the data to be operated and the operation added to the data are nodes, and the temporal change of the nodes is an arc.

Further, the effective graph is characterized in that the operation canceled by the user is branched.

The operation sequence conversion method of the present invention converts an operation sequence performed by a user on data into an effective graph by the following method.

1. The operation target data becomes the start point node. The operation performed on the data becomes the next node,
Data and operations are connected by an arc. Hereinafter, each time an operation is performed, nodes representing the operation are added to the graph one after another. When the operation ends, a node representing the data at the end of the operation is added to the end of the effective graph.

2. When the user cancels the operation and then performs the operation again, a node indicating a new operation is added after the node indicating the operation immediately before being canceled. The canceled operation is represented as a branch of the effective graph.

Further, this effective graph is displayed in a form that can be edited and reused by the following method.

1. Display Method (a) A node indicating data is displayed as an appropriate figure.

(B) The node indicating the operation is displayed as a character string obtained by converting the operation into a command.

(C) The arc is displayed as a straight line.

2. The effective graph can be edited as follows using a pointing device such as a mouse.

(A) Arc deletion and reconnection (b) Node deletion possible

[0017]

In the operation sequence conversion method and display method of the present invention, 1. Since the operation sequence is converted into an effective graph and the effective graph can be edited using the same device as the data operation, the burden on the user is small.

2. Since the operation canceled by the user is expressed as a branch of the effective graph, the canceled operation can be effectively reused.

[0019]

The present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of the configuration of the device of the present invention. The data operation environment (5) is an environment for interactively operating data. The operation interpretation unit (7) converts an interactive operation performed by the user using a pointing device or the like into a command for data.

The converted instruction is applied to the data by the instruction execution unit (6).

FIG. 2 shows an example of an interactive data operation environment. It is possible to manipulate tabular data in the following ways.

1. Row, column, selected using the mouse
Delete, insert, copy, and paste operations on the rectangle with the buttons on the left side of the screen. A value is input to each element from the keyboard. The operation sequence storage unit (4) stores the operation sequence converted into a command by the operation interpretation unit (7). The operation sequence conversion unit (3)
The operation sequence stored in the operation sequence storage unit (4) is converted into an effective graph (9) by the following procedure.

1. 1. The data to be operated is the starting point node. A node is an operation added to data. 3. Draw an effective arc from the start point node to the operation node. Below, add an operation node every time an operation is added,
4. Draw an effective arc from the previous operation node. The operation canceled by the user is converted into a branch of the effective graph. For example, when the user operates in the order of operation 1 → operation 2 → operation 3 → cancel → cancel → operation 4, an effective graph as shown in FIG. 3 is generated.

The operation sequence display section (2) presents the effective graph to the user in an editable form. At this time, the node indicating the data is displayed as a picture, and the operation is displayed as a character string indicating the command. The displayed effective graph can be edited as follows with a pointing device such as a mouse.

1. Replacement of the arc 2. Delete and copy node 3. Partial Extraction of Effective Graph The operation sequence execution unit (10) re-executes the operation sequence based on the effective graph edited by the user.

By the above procedure, the operation sequence can be converted into an effective graph, edited by the user, and reused.

[0028]

As described above, according to the operation sequence visualization apparatus of the present invention, the sequence of operations performed by the user on the data is the operation target data, the start point / end point nodes, and the added operation. , Which is an intermediate node, is converted into an effective graph connected by arcs according to the temporal order, and is presented to the user in a form that can be edited and reused. Moreover, the operation canceled by the user is expressed as a branch of the effective graph.

As a result, 1. Since the operation sequence is converted into an effective graph and the effective graph can be edited using the same device as the data operation, the burden on the user is small.

2. Since the operation canceled by the user is expressed as a branch of the effective graph, the canceled operation can be effectively reused.

The effect is as follows.
