Abstract

Provided is a network system including at least first and second communication terminals capable of communicating with each other via a network. The first communication terminal causes handwritten data input in response to an instruction for a point on an image to be displayed in a certain position on the image corresponding to this point, associates the point information about the point with the handwritten data and transmits the point information and the handwritten data to the second communication terminal. Based on the point information and the handwritten data from the first communication terminal, the second communication terminal causes at least a part of the image to be displayed on a second display and also causes the handwritten data to be displayed in a location in accordance with the point information.

Claims

1. A network system including at least first and second communication terminals capable of communicating with each other via a network,

said first communication terminal comprising:

a first display;

a first communication device; and

a first processor causing an image to be displayed on said first display, causing handwritten data input in response to an instruction for a point on said image to be displayed in a certain position on the image corresponding to said point, associating point information about said point with said handwritten data, and causing said first communication device to transmit the point information and the handwritten data to said second communication terminal,

said second communication terminal comprising;

a second display;

a second communication device; and

a second processor, based on said point information about said point and said handwritten data from said first communication terminal, causing at least a part of said image to be displayed on said second display and causing said handwritten data to be displayed in a location in accordance with said point information.

2. The network system according to claim 1, wherein said image is greater in size than said second display.

3. The network system according to claim 1, wherein

said second processor determines whether or not said point in said image is displayed on said second display, and

when said point is displayed, said second processor causes said handwritten data to be entirely displayed on said second display based on said point information.

4. The network system according to claim 3, wherein

when said point is displayed, said second processor determines whether or not said second display can entirely display said handwritten data, and

when said second display cannot entirely display said handwritten data, said second processor causes said handwritten data to be moved based on said point information, thereby allowing said handwritten data to be entirely displayed on said second display.

5. The network system according to claim 3, wherein

when said point is displayed, said second processor determines whether or not said second display can entirely display said handwritten data, and

when said second display cannot entirely display said handwritten data, said second processor reduces a size of said handwritten data based on said point information, thereby allowing said handwritten data to be entirely displayed on said second display.

6. The network system according to claim 3, wherein, when said point is not displayed, said second processor causes said handwritten data to be displayed in a prescribed position on said second display.

7. The network system according to claim 6, wherein, when said point is not displayed, said second processor causes an image showing a direction of said point to be displayed on said second display.

8. The network system according to claim 1, wherein said image is a map.

9. A communication method in a network system including at least first and second communication terminals capable of communicating with each other via a network, said communication method comprising the steps of:

said first communication terminal receiving an instruction for a point on an image;

said first communication terminal receiving an input of handwritten data;

said first communication terminal causing at least a part of said image to be displayed on a first display and causing said handwritten data to be displayed in a location corresponding to said point;

said first communication terminal associating point information about said point with said handwritten data and causing a first communication device to transmit said point information and said handwritten data to said second communication terminal; and

based on said point information and said handwritten data from said first communication terminal, said second communication terminal causing at least a part of said image to be displayed on a second display and causing said handwritten data to be displayed in a location in accordance with said point information.

10. A communication terminal capable of communicating with another communication terminal via a network, said communication terminal comprising:

a display;

a communication device; and

a processor causing handwritten data input in response to an instruction for a point on an image displayed on said display to be displayed in a certain position on the image corresponding to said point, associating point information about said point with said handwritten data, and causing said communication device to transmit said point information and said handwritten data to said another communication terminal.

11. A communication terminal capable of communicating with another communication terminal via a network, said communication terminal comprising:

a display;

a communication device; and

a processor, based on point information and handwritten data from said another communication terminal, causing said display to display said handwritten data in a location in accordance with said point information.
