JPH0317762A - Handwritten input type conversation device - Google Patents

Abstract

PURPOSE:To attain a smooth conversation between the remote places by performing the inter-field communication and a drawing process of the input data. CONSTITUTION:When both sides try to start input operations, the drawing data is inputted from a system 1 via a handwritten input means 3. Thus a drawing data analyzing means 10 informs the start of input to a transmission right control means 8. The means 8 changes its own state into a transmission right request state and informs a transmission right control means 18 of the reception side of the request of the transmission right via a communication medium 100. If a request is received from a system 2 for the transmission right, the means 8 knows that the system 2 is not ready for transmission/reception and inhibits the means 10 from analyzing data and transferring the data to a data output control means 17. At the same time, the means 18 is ready again for transmission/reception by itself. Thus it is possible to always keep the coincidence of display contents between both systems and to perform the smooth interaction between them.

[Embodiment] Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment in which a handwritten input type dialogue device W1 and a handwritten input type dialogue device 2 according to the present invention are connected through a communication medium 100.

First, the ellipse of this embodiment will be described.

The handwritten input dialogue devices 1 and 2 of this embodiment each have the following features:
A handwritten input input stage 3 and 13 for inputting handwritten data, and a file storage for storing data received from the data output control means 7 and 17 and extracting the data to the drawing data analysis means 10 and 20 or the command data analysis means 1l and 21. means 4 and 14, command input steps 5 and 15 for inputting commands such as erasing the screen and retrieving data from the file storage means 4 and 14, and output means 6 and 1 for displaying drawing results.
6, and data output control means for receiving data from the drawing data analysis means 10, 20 or command data analysis means 11, 21 and passing the data to the output means 6, 16, the communication medium 100, and the file storage means 4, 14. 7
17, and the drawing data analysis means 10 which receives input start/end notifications from the drawing data analysis means 10, 20 or command data analysis means 11, 21, and requests or notifies the other party for transmission rights. 20 or the command data analysis means 11 and 21 to notify that it is prohibited to pass the data to the data output control means 7 and 17, and to respond to requests for transmission rights and notifications of transmission completion from the other party. Transmission right control means 8 and 18 return the data to the other party and manage the state of its own system, and receive data from the other party through the communication medium 100, analyze the data, and thereby draw data analysis means 10 and 20 or command data. Received data analysis means 9 and 19 pass data to analysis means 11 and 21, and data output control means analyzes drawing data obtained from the handwriting input means 3 and 13, file storage means 4 and 14, or the received data, and outputs the results. 7.17
The transmission right control means 8.1 controls the start and end of input.
A command that analyzes command data acquired from the command input means 5, 15, file storage means 4, 14, or received data, and passes the result to the data output control means. It consists of data analysis means 11 and 21. The operation of this embodiment will be described below.

Regarding this, there are two cases in which both parties are able to send and receive and one of them starts inputting, one is in the process of inputting when the other tries to start inputting, and both are in the state where both are able to send and receive and both start inputting at the same time. The explanation will be divided into three cases, including the case where you try to start.

First, a case will be shown in which one of the two parties starts inputting data while both parties are capable of sending and receiving data.

Immediately after the start-up of both handwritten input type dialogue devices, both are in a state where they can send and receive data, and when one of them, for example, the user of the handwritten input type dialogue device 1 (hereinafter referred to as "system 1"), uses the handwritten input means 3. Immediately after starting the input of drawing data, the drawing data analysis means 10 notifies the transmission right control means 8 of the start of input of drawing data. After receiving the notification of the start of drawing data input, the transmission right control means 8 confirms that its own state is in the transmitting/receiving state, sets its own state to the transmitting right requesting state, and transmits the request to the other party via the communication medium 100. A request for a transmission right is notified to the transmission right control means 18 of the receiving side, that is, the handwritten input type dialogue device 2 (hereinafter referred to as "system 2").

Furthermore, after confirming that the receiving side transmission right control means 18 is in a transmitting/receiving state, the receiving side transmission right control means 18 sets its own state to a receiving state, and requests the received data analyzing means 19 to transmit or receive drawing data or command data from now on. Notify reception. At the same time, the transmission right control means 18 notifies the transmission right control means 8 on the sending side via the communication medium 2 of acceptance of the request. The sending side sending right controlling means 8, which has received the notification of request acceptance from the other side sending right controlling means 18, sets its own state to the transmitting state, and sends the drawing data inputted from the handwritten input means 3 to the drawing data analyzing means 10. The data output control means 7 is notified of permission to pass the data to the data output control means 7. The drawing data analysis means 10 that received the notification of permission,
The drawing data acquired by the handwriting input means 3 is passed to the data output control means 7 until the user of the system 1 finishes inputting using the handwriting input means 3.

Furthermore, the data output control means 7 which received the drawing data passes the drawing data to the output means 6 and also to the received data analysis means 19 on the receiving side via the file storage means 4 and the communication medium 100. Output means 6 that receives drawing data
displays the drawing results, and the file storage means 4 stores the drawing data. The reception data analysis means 19 determines the received data as drawing data, and passes the drawing data to the drawing data analysis means 20. The drawing data analysis means 20 which received the drawing data analyzes the drawing data and then passes the drawing data to the data output control means 17. Since the transmission right control means 18 is in the receiving state, the data output control means 17 determines that the received data has been sent from the other party, and transfers the drawing data to the file storage means 14 and the output means 1.
Pass it to 6. File storage means 1 that receives drawing data
Reference numeral 4 stores drawing data, and output means 16 displays drawing results.

When the user of the system 1 finishes inputting using the handwritten input means 3, the drawing data analysis means 10 notifies the transmission right control means 8 of the end of input data. Upon receiving the notification, the transmission right control means 8 notifies the receiving side transmission right control means 18 of the completion of data transfer via the communication medium 100. The receiving side transmission right control means 18 notifies the received data analysis means 19 of the completion of data reception, and changes its own state to a receivable state. At the same time, transmission right control means 1
8 notifies the sending side transmission right control means 8 of acceptance of termination via the communication medium 100. Upon receiving the termination notification, the transmission right control means 8 on the transmitting side changes its state to a transmitting/receiving state and waits for the next input. Follow the same procedure for inputting command data. Next, we will show the case where one person tries to start inputting while the other person is inputting data. When the user of the system 2 inputs data using the handwriting input means 13 while the user of the system 1 is in the process of inputting data using the above procedure, the drawing data analysis means 20 starts transmitting the drawing data. Notice. However, since the transmission right control means 18 is in the receiving state, it notifies the drawing data analysis means 20 of the prohibition of analyzing the drawing data and passing the drawing data to the data output control means 17. In response to this, the drawing data analysis means 2
0 ignores the acquired drawing data until the input by the handwriting input means 13 is completed, and warns the user if necessary. A similar procedure is followed for inputting command data.

Finally, the case where both parties try to start input at the same time is shown.

When the user of the system 1 starts inputting drawing data using the handwriting input means 3, the drawing data analysis means 10 notifies the transmission right control means 8 of the start of inputting drawing data. After confirming that the transmission right control means 8 is in a transmitting/receiving state, the transmission right control means 8 changes its own state to a transmission right requesting state.
A request for the transmission right is notified to the transmission right control means 18 on the receiving side via the communication medium 100. However, by following the same procedure and receiving a request for transmission rights from the system 2, the transmission rights control means 8 learns that the system 2 is not in a state in which transmission and reception are possible, and requests the drawing data analysis means 10 to analyze the data. , notifies the prohibition of passing the data to the data output control means 17. At the same time, the transmission right control means 18
changes its state to a transmitting/receiving state again. In other words, simultaneous transmission of both is prohibited. A similar procedure is followed for inputting command data.

As a result of the above, the sameness of the display contents on both sides is always maintained in any case.

[Effects of the Invention] As explained above, the present invention uses a handwritten input means that allows both parties to view the same display on the output means, and the input method is simple and quick. By doing so, it is possible to conduct dialogue between remote locations very easily and smoothly, and it has the effect of supporting sufficient communication of intentions on both sides.
