ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of Invention
The invention relates to a manually input data display system, and a coordinate data input device and a display device for use in the manually input data display system.
2. Description of Related Art
FIG. 36
shows a conventional manually input data display system. For example, a presentation apparatus, including a personal computer (hereinafter referred to as the “PC”)
1
and a display device
2
connected to each other, is provided in each of conference rooms. The PCs
1
in each of the conference rooms may conduct communications therebetween through, for example, a telephone line. The display device
2
may include, for example, a projector
3
, and a display board
4
provided with a pressure-sensitive touch sensor.
When a conference is held using remotely located conference rooms, the PC
1
is operated in any of the conference rooms, so as to throw an image of data, which is stored in the PC
1
or an external memory, onto the display board
4
, using the projector
3
. The same data is transmitted to the PCs
1
provided in other conference rooms, through the telephone line, so that the same contents may be displayed on the display board
4
in every room. With the above-described structures, participants in each of the conference rooms can hold a meeting while seeing the display board
4
, with the same contents presented in each room.
For example, when a participant writes a character or a graphic on a surface of the display board
4
, using a writing implement
5
to provide some additional information to the contents currently presented on the display board
4
, a pressure applied during writing is sensed by the pressure-sensitive touch sensor, thereby obtaining coordinate data for the input. The coordinate data is transmitted to the PC
1
. Also, the coordinate data is transmitted to other PCs
1
provided in the conference rooms, through the telephone line.
In the above-described conventional presentation apparatus, the image of the characters/graphics is thrown by the projector
3
onto the display board
4
on which the characters/graphics may be written. When the additional information is written on the display board
4
where the image of the characters/graphics has already been displayed thereon, it becomes difficult to recognize the contents on the display board
4
. In addition, when the image of the characters/graphics added to the display board
4
of a different conference room is overlaid on the image of the characters/graphics thrown by the projector
3
onto the display board
4
of a conference room, it is difficult to understand which contents are written by whom or in which rooms.
SUMMARY OF THE INVENTION
Accordingly, one exemplary aspect of the invention is to provide a manually input data display system, and a coordinate data input device and a display device for use in the manually input data display system, in which data, such as text and graphics manually input by a user, is displayed in an easy-to-see arrangement.
A manually input data display system of the invention may include a plurality of coordinate data input devices and at least one display device. Each of the coordinate data input devices may include a coordinate data acquisition unit that obtains images manually input from the coordinate data input devices as coordinate data, a coordinate controller that controls processing of the coordinate data obtained by the coordinate data acquisition unit, and a transmitter that transmits the coordinate data. The display device may include a receiver that receives the coordinate data transmitted from the plurality of the coordinate data input devices, a display controller that controls processing of the coordinate data received through the receiver, and a display unit that displays the manually input images based on the coordinate data. The display controller of the display device may divide a display area of the display unit into a plurality of individual display areas corresponding to the plurality of coordinate data input devices, and a selective display area that selectively displays the images displayed in the individual display areas.
In the manually input data display system, when a user sees the display unit, the user may easily understand from which coordinate data input device (by which participants) contents displayed in each of the individual display areas are input. Among the contents displayed in the individual display areas, a particular content may be selected and displayed in the selective display area. With the above-described structure, main points in a conference may be easily organized.
The coordinate controller of each of the coordinate data input devices may transmit the coordinate data obtained by the coordinate data acquisition unit, with an identification information of each of the coordinate data input devices attached to the coordinate data. The display controller of the display device may identify the identification information attached to the coordinate data received through the receiver, and display the images input in each of the coordinate data input devices on the corresponding individual display areas, based on the coordinate data. When it is determined that the images displayed in the individual display areas satisfy a predetermined condition, the display controller of the display device may shift the images displayed in the individual display areas to the selective display area.
The display controller of the display device may display the images in the individual display areas corresponding to the coordinate data input devices, by identifying the identification information attached to the coordinate data. When the predetermined condition is satisfied, the display controller of the display device may shift the images displayed in the individual display areas to the selective display area, so that the images are displayed in the selective display area
The display controller of the display device may determine, based on the identification information attached to the coordinate data, whether the images corresponding to the coordinate data are to be displayed in the display unit.
When a conference or meeting is held between people in remotely located conference rooms, the display device provided in each of the conference rooms may display the images input by the participants in the other rooms. Such structures may be employed when the need to display the images input on one of the coordinate data input devices in a room, on the display device in the same room, is relatively low. Thus, a display area of the display device may be effectively used.
Each of the coordinate data input devices may further include a designation unit that designates the images displayed in any of the individual display areas. When the display controller of the display device receives data designating the images selected by the designation unit from any of the coordinate data input devices, through the receiver, the display controller of the display device determines that the designated images displayed in the individual display areas satisfy the predetermined condition.
When the user performs a designation operation using the designation unit, the images displayed in the individual display areas may be shifted to the selective display area, while reflecting the user's intentions.
Each of the coordinate data input devices may further include a designation unit that designates the images displayed in any of the individual display areas. When the display controller of the display device receives data designating the images selected by the designation unit of at least one of the coordinate data input devices, through the receiver, the display controller determines that the images displayed in one of the individual display areas, which is designated the most important, satisfies the predetermined condition.
When the users designate, on the designation unit, the images displayed in the individual display areas that the users think are to be selected, the images displayed on one of the ind
