Description

 The present invention publishes desktop information (hereinafter referred to as a screen) of its own client (explainee terminal) and performs marking such as a circle or a straight line on the screen of its own client in response to writing of the other client (explainer terminal) It is about.

With the widespread use of personal computers and the Internet, various services are provided every day, and personal computers are now owned by people other than those who are usually engaged in computer-related work.
However, when enjoying these various services, settings and operations are often different depending on the individual services, and it is particularly difficult for those unaccustomed to personal computers to enjoy these services.

In other systems currently used, (1) unilateral information transmission of the screen information of the own client, or (2) temporary transfer of the operation authority of the partner client computer to the partner.
In the system of (1), there is a lack of information when the displayed items differ depending on the setting of the partner screen and the own screen. In the system of (2), the partner can freely access his client's folder, etc. I feel uneasy about infringement of privacy and security issues against malicious operation of the other party.
There are many references (1), for example, the NetMeeting system of MicroSoft (Non-patent Document 1).
There are many references in (2), for example, a remote desktop system (Non-Patent Document 2) of MicroSoft.

MicroSoft's NetMeeting system

MicroSoft Remote Desktop System

By the way, instead of reading a few pages of manuals and instructions when an individual wants to enjoy each service, or to make a contract such as insurance, or when you don't know how to operate a personal computer, you can use the telephone or the Internet. There is a need to request explanations of operation methods and important matters from the other person in charge, acquaintances and friends.
However, companies that have a dedicated support center can develop functions that allow them to perform the same operations as their own users, or have specialized staff, but other companies, acquaintances, and friends explain to the other party. In this case, there is a problem that (1) what kind of screen is currently open is not known (2) how much the other party has knowledge of the personal computer is not known.

As an example of (1), when the “My Computer” icon is hidden in the Windows (registered trademark) system of MicroSoft, it is not possible to tell the other party that “Click the icon of My Computer”. It is done.
As an example of (2), even if “icon” is transmitted, the word “icon” may not be known.
Specialized staff are educated on how to explain to those who are unfamiliar, so you can explain to others by using easy-to-understand words, but those that have not received sufficient education It is difficult to explain to the other party by words alone.

However, no matter how concise and easy-to-understand words are used by professional staff, there is not enough information to convey and understand them with words alone.
In fact, there are cases where explanations are difficult to understand due to inadequate education of the professional staff at Support Santa, or the explainer is busy with dealing with other questioners and does not have enough time to explain.

  Therefore, an object of the present invention is to provide a system in which an instructor receives information on a screen displayed by the other party and realizes transmission of important matters and guidance of the next operation by marking on the other party screen. is there.

In order to achieve the above object, the marking system for other clients of the present invention connects a questioner's terminal and a presenter's terminal via a network, and displays graphic information input to the presenter terminal on the questioner terminal. A marking system for other client screens,
The interrogator terminal
Means for acquiring, compressing and transmitting the information of the own screen to the presenter terminal; means for drawing a corresponding figure on the display screen based on the figure information acquired from the previous explainer terminal through the network; and drawing on the display screen A means for deleting a previous figure when a display time of the figure elapses for a certain period of time or when a figure is newly drawn, and a means for allowing only the drawing authority to the explainer terminal;
The explainer terminal is
The screen information of the questioner received from the questioner terminal is decompressed and displayed on the self-screen, the figure input from the input device is shaped, information indicating the type of figure such as a circle or a line, and the characteristics of the figure Means is provided for transmitting point information (in the case of a circle, the center and radius of the circle, and in the case of a straight line, the start point and the end point) to the questioner terminal.

The present invention has the following effects.
(1) Since the explainer can explain after seeing the same screen as the questioner, it is easy to determine the situation of the partner screen. It can absorb differences in screen display due to individual settings and differences in display depending on the operating system.
(2) At the time of explanation, not only words but also important matters and next operations are conveyed by marking, so that the level of understanding of the questioner can be improved and the time required for explanation can be shortened.
(3) Cost reduction for developing unique functions for questioners can be achieved.
(4) Since the explainer can only mark the screen of the questioner, the final decision is left to the questioner, and personal information protection such as non-explainer's personal folder cannot be freely referred to Also consider.

1 is a system configuration diagram showing an embodiment according to the present invention. FIG. 2 is a functional block diagram schematically showing an internal configuration of a terminal 101 shown in FIG. 1. It is a functional block diagram which shows roughly the internal structure of the terminal 102 shown in FIG. It is explanatory drawing of the process which specifies the drawing position and form on a screen. It is a flowchart of a process of an interrogator terminal and an instructor terminal.

Hereinafter, the present invention will be described in detail based on the illustrated embodiments.
FIG. 1 is a system configuration diagram showing an embodiment according to the present invention.
In the marking system for the questioner of this embodiment, the questioner terminal 11, the explainer terminal 12 and the external input device 13 are configured. The questioner terminal 11 and the explainer terminal 12 are connected by a network. 13 is connected to the explainer terminal 12.
The external input device 13 has a shape that makes it easy for the explainer to draw a figure on the explainer terminal 12, such as an electronic pen.

FIG. 2 is a functional block diagram schematically showing the internal configuration of the questioner terminal 11.
In FIG. 2, the transmission / reception unit 21 controls the exchange of data with the presenter terminal 12, and the data processing unit 22 (1) acquires and processes information on the display unit 23 and passes it to the transmission / reception unit 21. (2) A drawing processing unit 222 that processes data received from the transmission / reception unit 21 and outputs the processed data to the display unit 23 is provided.
The screen data processing unit 221 performs processing such as data compression in order to intermittently transmit information shown on the screen to the questioner terminal 11 to the explainer terminal 12.
In general, when transmitting screen information, a screen capture is acquired and image data is transmitted to the other party. The image data has a large capacity, and in the present invention, the image data must be intermittently transmitted to the explainer terminal 12, so that a processing unit that performs data compression in consideration of reducing the load on the network is required. .

The drawing shaping unit 222 holds the drawing position information received from the explainer terminal 12, the drawing form (circle, straight line), the drawing time of the figure, and calculates which figure should be drawn at which position. And a function for accumulating information on the figure drawn immediately before.
The reason why the information of the figure drawn immediately before is stored in the drawing processing unit 222 is to perform control to delete the figure after a certain time describing the figure. For example, the figure is erased 5 seconds after the figure is drawn on the screen, or the figure drawn before when another figure is newly drawn is erased. This is because if the previous figure remains, there will be a plurality of figures on the screen, making it difficult to understand the screen. In particular, when explaining the insurance contract, the explanation will be hindered if the previous figure remains for “things whose screen changes”.
In addition, the display unit 23 points to the screen of the questioner terminal 11 and draws a figure on the screen in accordance with a command from the drawing processing unit 222.

FIG. 3 is a functional block diagram schematically showing the internal configuration of the explainer terminal 12.
In FIG. 3, the transmission / reception unit 31 controls the exchange of data with the questioner terminal 11, and the data processing unit 32 (1) a screen for decompressing the data received from the transmission / reception unit 31 and transmitting the data to the display unit 33. A data display processing unit 321 and (2) an input information processing unit 322 that acquires information (position information, drawing form) of the input unit 34 and passes the information to the transmission / reception unit 32 and the display unit 33.
The display unit 33 indicates the screen of the explainer terminal 12, and the input unit 34 acquires from the input information of the external input device 13 where it is described on the screen and what figure is drawn.
There are various techniques for the drawing shaping method. For example, there is an intelligent pen shaping technique used in StarBoard of Hitachi Software Engineering Co., Ltd.

FIG. 4 is a sample when information is drawn on the explainer terminal 12 using the external input device 13 and when a figure is drawn on the questioner terminal 11.
In the case of the explainer terminal 12, the figure drawn on the screen is first shaped by the automatic shaping technique described above.
If the coordinates at the upper left of the screen are (x0, y0), the coordinates at the lower right are (x1, y1), and the entire screen is the coordinates, the circle center (a0, b0) of the circle 42 and the right outer periphery of the circle ( a1, b1) are obtained and the radius is obtained.
In the case of the straight line 43, the left end (c0, d0) is obtained as the start point, and the right end (c1, d1) is obtained as the end point.
The explainer terminal 12 transmits this information (graphic type (circle, straight line) and feature point information (circle center, radius, straight line start point, end point) to the interrogator terminal 11 through the transmission unit 31.
The questioner terminal 11 displays the information on the display unit 23 based on these pieces of information.

FIG. 5 is a flowchart showing an outline of processing of the questioner terminal 11 and the explainer terminal 12.
First, the interrogator terminal 11 transmits its own client information (IP address) to the explainer terminal 12 via the transmission / reception unit 21 (step 501).
In response to the information from the questioner terminal 11, the explainer terminal 12 receives the information at the transmission / reception unit 31, and confirms the connection of the external input device 13 (step 502).

If the preparation is completed, a response of “Ready” is returned to the questioner terminal 11 via the transmission / reception unit 31, and a response of “Preparing” is returned if the preparation is not completed (Step 503).
The interrogator terminal 11 determines the response result received from the transmission / reception unit 21 (step 504). If the response result (step 503) is “ready”, the screen data processing unit 22 acquires and processes the information on the own screen. The screen data is transmitted to the explainer terminal 12 through the transmission / reception unit 21 (step 505). If the response result (step 503) is “in preparation”, the process from step 501 to step 503 is repeated until the explainer terminal 12 becomes “preparation complete” or disconnects at the inquirer terminal 11.

The explainer terminal 12 decompresses the screen information from the questioner terminal 11 acquired by the transmission / reception unit using the screen data display processing unit 321 and displays it on the display unit 33. (Step 506).
The presenter draws a figure on the own screen using the external input device 13 (step 507).
The input information processing unit 322 calculates the information (position information and graphic type) input in step 507 and transmits data to the questioner terminal 11 and the display unit 33 (step 508).
The display unit 33 draws the acquired graphic as it is.
If there is information received from step 508 through the transmission / reception unit 21, the interrogator terminal 11 performs graphic drawing processing. When there is no writing in the explainer terminal 12 (that is, when no information is transmitted from the explainer terminal 12), the process returns to the process of intermittently sending the screen information of the interrogator terminal 11 (step 509).

When the explainer draws a figure, a process of drawing on the questioner terminal 11 is performed. First, it is checked whether the figure already exists in the questioner terminal 11 (step 510).
The graphic shaping unit 222 holds the previous graphic information.
If the graphic already exists, the information of the drawing shaping unit 222 is initialized, and the graphic is deleted (step 511).

Next, the information of the input information unit 322 acquired through the transmission / reception unit 21 is stored in the drawing shaping unit 222, and the drawing position and figure are specified (step 512).
The drawing shaping unit 222 transmits position information and graphic information to the display unit 23, and the display unit draws a graphic based on this information (step 513).
Also, regardless of whether or not there is a writing from the presenter, a process of deleting a figure is performed after a certain period of time. This compares the drawing time held in the drawing shaping unit 222 with the current time (step 5141). If a certain time has passed, the information of the drawing shaping unit 222 is initialized and the figure is deleted (step 5142). ).
This series of work is performed until the network disconnection or the information transmission end of the questioner terminal 11 or the explainer terminal 12 is executed.
