Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for displaying a plurality of cursors in a group conference, and more particularly to a method and apparatus for displaying the operation result of a pointing device held by each attendee on a large screen supported by a computer. Regarding the device.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication (Kokai) No. 61-198891 discloses a conventional conference for detecting a speaker and attempting to smooth it. This aims to facilitate the conference by capturing the voice of the speaker with a directional microphone to identify the speaker, capturing it with a camera and taking a close-up so that the viewer can see at a glance who is speaking. It is something to try.

[0003]

However, even if a specific speaker in the conference can be captured by the camera and displayed on the screen, the conference using the large screen supported by the electronic conference or the computer instead of the blackboard or the OHP. In many cases, the display content is often shown from a position away from the speaker, and it is difficult for other attendees to recognize the operation. Also, since the camera captures only one speaker at a time, it is difficult for all attendees to recognize when multiple speakers are speaking at the same time, such as in a debate, or where the displayed part of each is displayed. there were.

It is an object of the present invention to make it easier for other attendees to understand where the current speaker is in a group meeting, and all who are present in the conference are indicated by the current speaker. It is an object of the present invention to provide a cursor display method and device that make it easy to focus a portion.

Another object of the present invention is to be able to always confirm where the cursor is, and even when the pointing device is suddenly operated, the relative positional relationship on the screen is recognized and the precise operation is performed. To do.

[0006]

In order to achieve the above object, a cursor display method of the present invention is to identify and display a corresponding cursor on a large screen of a display device when a pointing device operator is speaking. It is characterized by. In particular, normally, the cursors corresponding to a plurality of pointing devices are displayed on the large screen of the display device, and when the pointing device operator is speaking, the corresponding cursors are highlighted. In addition, the elapsed time after the pointing device operator speaks is measured, and the display mode of the identified and displayed cursor is changed according to the measured time (the transparency of the cursor is increased, the display position of the cursor is returned to the home position). , The display area of the cursor is reduced).

Further, it is also characterized in that the cursor for the pointing device is enlarged and displayed in a size larger than the characters displayed on the large screen of the display device, semi-transparent display, contour display and the like.

The cursor display device of the present invention comprises a plurality of pointing devices corresponding to a plurality of operators, a sound pressure sensing device which is paired with the pointing device to detect a speech at a conference, a pointing device and sound pressure. A pointing device control device for transferring information of the sensing device in pairs, a display control device for changing the cursor display at the position indicated by the paired pointing device based on the utterance detected by the sound pressure sensing device, and a sound pressure And a display device for displaying at least a cursor by the display control device. Specifically, when any of the sound pressure sensing devices detects the sound pressure, the transparency of the cursor at the position indicated by the pointing device paired with the sound pressure sensing device is minimized, and then the sound pressure sensing device. Does not detect sound pressure, and changes the transparency of the cursor to another predetermined transparency after a predetermined time elapses. When one of the sound pressure sensing devices detects sound pressure, a cursor is displayed on the large screen of the display device corresponding to the position indicated by the pointing device paired with the sound pressure sensing device, and then the sound pressure sensing device is detected. The sound pressure sensing device that has detected the sound pressure does not detect sound pressure, and the cursor is moved until it reaches a certain position on the large screen after a certain predetermined time elapses.

[0009]

The present invention provides a means for displaying the pointing device operated by the current speaker as a cursor most easily recognized by other attendees in a group conference in which the speaker changes every moment. That is, (a) Since each attendee has a pointing device and a sound pressure sensing device, each movement of the pointing device becomes an operation of each attendee, and the movement of the pointing device is further controlled by each sound pressure sensing device. It is possible to determine whether it is a significant operation associated with a utterance, and (b) time management makes the position of the cursor clear to attendees during a utterance and temporary interruption of a utterance associated with a discussion with another person, and changes the agenda. At the end of remarks made by, etc., the attendee's attention is drawn to the cursors of other speakers by not clearly indicating the cursor position to the attendees. (C) Time management is in the middle of remarks and accompanying discussions with other people. Temporary interruption of the speech gives the speaker control of the cursor, and when the speech is finished due to the change of the agenda, etc., the cursor display device keeps the cursor in the way of the attendees' understanding of the screen. So that it doesn't come back to a fixed position on the screen, and to draw attention to the cursors of other speakers, (d) possibly combining all of them, and (e) using a cursor of sufficient size. , By urging attendees to pay attention to the point position on the large screen, and by using (f) translucent cursors, show all information on the screen to attendees even when the displayed information is covered, and (g) with large cursors. By presenting hidden information to attendees, in a group meeting where the speaker changes every moment, the pointing device operated by the current speaker can be easily recognized by other attendees and the visibility of the display screen can be improved. It is displayed as an unobstructed cursor.

In this manner, the cursor of the person who is currently speaking is displayed in the most emphasized state, and the cursors of other persons are suppressed and displayed, so that all the conference participants can be pointed to by the current speaker. It becomes easier to recognize the displayed part and you can concentrate on the agenda.

Further, since it is possible to always confirm where the cursor is, it is possible to recognize the relative positional relationship on the screen and perform an accurate operation even when the pointing device is suddenly operated. .

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is an overall conceptual diagram of a group conference to which the present invention is applied. In FIG. 1, 10 is a large-scale display device such as a high-definition projection display for displaying conference materials, 11, 12, 13, 14, 15, 16, 17, 1.
8, 19, 20, 21, 22, 23, and 24 are pointing devices such as a mouse for designating display positions on the display device, 31, 32, 33, 34, 35, 36, 37, and 3.
8, 39, 40, 41, 42, 43, 44 are 11, respectively.
12, 13, 14, 15, 16, 17, 18, 19, 2
Cursor, 51, 52, 53, 54, 55, 56, 5 which is the result of displaying the position designated by the pointing device of 0, 21, 22, 23, 24 on the display device 10.
7, 58, 59, 60, 61, 62, 63, 64 are 11, 12, 13, 14, 15, 16, 17, 18, 1 respectively.
This is a sound pressure sensing device provided corresponding to the pointing devices 9, 20, 21, 22, 23, and 24.

A description will be given here with reference to both FIG. 1 and FIG. FIG. 2 is a conceptual diagram showing one of the attendees of FIG. 1, and the attendee uses one pointing device and one sound pressure sensing device as shown in FIG.

In FIG. 2, the attendee operates the pointing device 17. At this time, the sound pressure sensing device 57 detects the utterance of the operator of the pointing device 17 as sound pressure. When the sound pressure sensing device 57 senses the sound pressure, the two-dimensional planar movement of the pointing device 17 is displayed on the display device 10.
This movement is reflected on the cursor 37 corresponding to the operator and displayed.

At this time, when another attendee operates the pointing device 14 and the sound pressure sensing device 54 senses the sound pressure of the operator of the pointing device 14, the cursor 3
A two-dimensional planar movement of the pointing device 14 together with 7 is displayed on the display device 10 as a cursor 34 (FIG. 1). This indicates a situation where another person speaks at the same time as the current speaker when discussing at a group conference or the like, or when another person speaks immediately after the end of the speech.

When no speech is detected by the sound pressure sensing device for a certain period of time, the cursor is, for example, on the lower side of the display device 10, regardless of the movement of the pointing device, the cursor 31, 32, 33, 35, 36, 38. , 39,
40, 41, 42, 43, 44 are sequentially arranged and wait. At this time, the standby position of the cursor corresponding to each pointing device on the display device 10 is predetermined in correspondence with the position of each pointing device. Here, it is sequentially displayed on the left side of the display device 10 and on the left side of the lower end of the display device 10 from the pointing device 11 near the display device 10 according to the device numbers. It should be noted that the positions of the cursors 34 and 37 that are currently being operated and displayed are empty.

According to the above method, when a large number of attendees use their pointing devices to discuss such as in a group conference, the cursor display is restricted to the attendees who are not currently speaking on the display device. Everyone can easily determine where the current topic is centered.

FIG. 3 shows the system configuration and data structure for holding a group conference. 151, 1 in FIG.
52 and 153 are sound pressure sensing devices, 154 is a pointing device control device, 155 is a display control device, 156 is a large display device, and 161, 162 and 163 are pointing devices that pair with the sound pressure sensing devices 151, 152 and 153, respectively. The device 164 is a timer, which is indicated by 1 in FIG.
Reference numeral 65 denotes a data structure output from the pointing device control device 154 to the display control device 155.

Each of the sound pressure sensing devices 151, 152 and 153 detects a sound pressure when a person wearing the sound pressure sensing device as shown in FIG. A detection signal is sent to 154. In addition, the pointing devices 161, 16
Reference numerals 2 and 163 detect the amount of movement for each fixed time for each x coordinate and y coordinate, and send a signal of the amount of movement coordinate to the pointing device control device 154. The pointing device control device 154 reads the signals of all the sound pressure sensing devices and the signals of the movement coordinate amount of the pointing device within a fixed time. The pointing device control device 154 sequentially displays the data of the data structure 165 composed of two sound pressure sensing devices and pointing devices which form a pair, to the display control device 15 in sequence.
Output to 5. The display control device 155 receives the data of the data structure 165 (see FIG. 3B) sent and the timer 16
Read the time data of 4. The display controller 155 reads the device number from the signal of the device number 165a, and if the sound pressure flag 165d is present, increments x,
The value of the y increment is read and the cursor coordinate corresponding to the device number currently displayed is moved. Further, the sound pressure flag detection time shown immediately before and held in the display control device 155 for each device number is replaced with the time of the timer 164. If the sound pressure flag does not exist, the sound pressure flag detection time and the timer 16 held immediately before the device number stored in the display control device 155 for each device number.
Compare 4 times. The attribute of the cursor sent to the display device can be controlled by this difference. A specific example of this will be shown later.

With this structure, it is possible to reflect the moving coordinate amount of the pointing device on the display device when the sound pressure is detected. Further, after the sound pressure is detected, the attribute of the cursor can be changed according to the passage of time, so that the result of operating the pointing device can be dynamically switched in combination with the utterance.

4 to 7 show a first cursor display method applied in the present invention. 71, 72, 73, 8 in the figure
Reference numeral 4 is a cursor, 74, 75, 76, 77, 78 and 79 are display contents, and 80, 81, 82 and 83 are display screens.

FIG. 4 is a conceptual diagram when a cursor is displayed on the screen of a general workstation. If the screen of the workstation is now 1280 × 1024 pixels and the size of the cursor is 16 × 16 pixels, the area ratio is 512.
It becomes 0 times. When this screen is displayed as it is on a large screen, the cursor is extremely small with respect to the size of the character font of several lines to several tens of lines per screen, and the visibility is deteriorated. Therefore, as shown in FIG. 5, when a large screen and large characters are instructed by using a large cursor 72, when a large number of attendees are present as in a group meeting,
All the participants can recognize the location of the display content 74 currently pointed to without error. Furthermore, by displaying the cursor 73 semi-transparently as shown in FIG.
It is possible to read the display contents 74 and 75 that are overlaid on the cursor 73.

On the other hand, like the cursor 84 shown in FIG.
It is also possible to read the display contents 74 and 75 by displaying only the outline of the cursor.

As described above, by making the cursor large and semi-transparently displayed, it is possible to clearly know where the cursor is currently pointing, and also to easily see what is being pointed at and what is under the cursor. Can be read. The semi-transparent display is not limited to the mixture of the light intensity of the cursor and the display surface, and may be a shaded display if it has a transparent feeling.

8 to 11 show a second cursor display method applied in the present invention. In the figure, 200 is the display content,
201, 202, 203, 204 are semi-transparent cursors, 2
Reference numerals 05, 206, 207, and 208 denote display screens, 211, and 2.
Reference numerals 12, 213 and 214 are time-series graphs of the sound pressure input to the sound pressure sensing device, and 215 is a sound pressure level at which the sound pressure sensing device detects that there is an utterance.

In the graphs 211, 212, 213 and 214, the right end 221 of the horizontal axis represents the present time, the left end of the horizontal axis represents the past time, and 222 indicates the present time when the sound pressure is not sensed until this time. Time is a start time at which the transparency of the cursor becomes large, and 223 is a change end time at which the transparency of the cursor does not become larger (not become transparent) when sound pressure is not sensed up to the present after this time.

When there is a sound pressure level higher than that indicated by 215 during utterance as shown in FIG. 8, the cursor displays with a certain degree of transparency.

On the other hand, as shown in FIG. 9, even if the current sound pressure cannot be detected, if the sound pressure can be detected up to the past indicated by 222 on the time axis, the cursor is displayed with the same transparency as in FIG.

Further, as shown in FIG. 10, when the current sound pressure cannot be detected and there is no utterance up to the past indicated by 222 on the time axis, the data on the time axis 222 from the present time is indicated by the time axis 223. Until moving to the time axis, the cursor is displayed with the transparency increased (transparent) at a certain rate.

Further, as shown in FIG. 11, when the sound pressure cannot be detected during the past indicated by the time axis 223 of the past from the present time on the graph, the time axis 223 of FIG. When there is no utterance from, the cursor is displayed while maintaining the transparency displayed on the time axis 221.

As described above, if the sound pressure is not detected for a certain period of time after the utterance, that is, the sound pressure is detected, it can be determined that the point at which the agenda is currently pointed has been separated, and thus the transparency of the cursor is changed. By making it large and displaying it inconspicuously to a large number of attendees, it becomes possible to draw the attendee's attention to other cursors. Furthermore, by not completely deleting the cursor, each attendee can know where the cursor that reflects his or her pointing device is located, so it is not necessary to confirm the position of the cursor when the next operation is performed, You can concentrate on the meeting. In the second cursor display method, not only the transparency is increased over time, but also the display area can be changed such that the cursor itself is reduced in size and displayed.

FIGS. 12 to 15 show the third embodiment applied in the present invention.
This is how to display the cursor. In the figure, 300 is a display content, 301, 302, 303, 304 are semi-transparent cursors, 305, 306, 307, 308 are display screens, 31
Reference numerals 1, 312, 313, 314 and 314 are time-series graphs of the sound pressure input to the sound pressure sensing device, and 315 is a sound pressure level at which the sound pressure sensing device detects that an utterance has occurred.

In the graphs 311, 312, 313, 314, the abscissa right end 321 represents the current time, the abscissa left end represents the past time, and 322 is the start time for moving the cursor.
Reference numeral 323 is a return time for returning the cursor to the home position.

As shown in FIG. 12, 315 is currently speaking.
When the sound pressure level is higher than that shown by, the cursor is operated by the pointing device, and the cursor is displayed at the position reflecting the operation.

On the other hand, even if the current sound pressure cannot be detected as shown in FIG. 13, if the sound pressure can be detected up to the past indicated by 322 on the time axis, the cursor is operated by the pointing device as in FIG. , The cursor is displayed at the position reflecting the operation.

Further, as shown in FIG. 14, when the current sound pressure cannot be detected and there is no utterance up to the past indicated by 322 on the time axis, the time remaining after performing the display as shown in FIG. Does not reflect the operation of the pointing device, and displays the cursor so that it moves toward a predetermined home position at a certain speed.

Further, as shown in FIG. 15, when the sound pressure cannot be detected during the past indicated by the past time axis 323 on the graph from the present, after performing the display of FIGS. 13 and 14,
Thereafter, the cursor is displayed at the home position displayed on the time axis 323 of FIG. 14 until the sound pressure is detected.

As described above, if the sound pressure is not detected for a certain period of time after the utterance, that is, the sound pressure is detected, it can be determined that the point at which the agenda is currently pointed has been separated, so that the cursor position is changed. By gradually returning to the home position and displaying it inconspicuously to a large number of attendees, it becomes possible to draw the attendee's attention to other cursors. In addition, the cursor returns to the home position decided for each attendee, so that each attendee can know where the cursor that reflects his or her pointing device is located, and the position of the cursor can be confirmed when he or she next operates. You don't have to, and you can focus on the meeting.

Although an example is not described here, FIG.
~ The examples of the second display method shown in Fig. 11 and the examples of the third display method shown in Figs. 12 to 15 may be used in combination.

FIG. 16 shows the process flow in the present invention by PA.
It is displayed in D. In FIG. 16, 401 is an infinite loop, 402 and 405 are N (N is a positive number) loops, 40
6, 411 are the judgment conditions, 403, 404, 407, 40.
8,409,410,412,413,414,415
Is the execution content.

Here, the system configuration and data structure shown in FIG. 3 will be cited, and a description will be given together with this.

In FIG. 3A, the sound pressure sensing device 151-
It is assumed that there are N 153 and N pointing devices 161-163. These two types always operate periodically under the control of the pointing device control device 154 of FIG. 3A as indicated by the infinite loop 401, and input processing of each sound pressure sensing device of FIG. Figure 3 at 404
The data including at least the position of each pointing device in FIG.
Transferred to. Data having the structure shown at 154 in FIG. 3A to 165 in FIG. 3A are collectively transferred to the display control device 155 in FIG. In 155 of FIG. 3A, the processing shown in 405 and below is performed on each transferred structural data.

First, using the data of 165d in FIG. 3B, it is judged at 406 whether the sound pressure is detected. If detected, the screen coordinates of the cursor to be displayed next are calculated based on the relative movement amount (165b, 165c) of the pointing device paired with this and the previous cursor position (408), and the cursor is highlighted. Display (409).
In the present invention, when the pointing device is not used for a long time with significance, that is, when the sound pressure is not detected for a long time, the display position of the cursor is managed independently at 155 in FIG. 3A. . Therefore, at 407, the current time from the timer 164 of FIG. 3A is referred to, and the latest use time (current time T) of each pointing device is registered in 155 of FIG. 3A.

If not detected at 406, the time at which each pointing device has not been used recently (sound pressure not detected) is determined at 410. In 411, when the pointing device has been used within a certain time (t ₀ ) from the present time, it is regarded as a temporary hibernation state, and the relative movement amount (165b, 165c) of the pointing device and the immediately preceding state are used. Calculate the screen coordinates of the cursor to be displayed next based on the cursor position (4
12), the cursor is highlighted (413). If it has not been used for a certain period of time (t ₀ ),
It is assumed that pointing has ended, and the screen coordinates of the cursor reflecting the pointing device are displayed regardless of the amount of movement of the pointing device.
Calculation is performed under the control of 155 of (a) (414), and the cursor is suppressed and displayed (415).

As described above, the display method of the cursor can be changed by the procedure shown in this PAD.
This is realized by detecting the movement of the pointing device and the utterance by the sound pressure sensing device, and by managing the time after the end of the utterance.

The present embodiment is a minimum for constructing this, and does not limit other elements other than this.

[0048]

As described above, according to the present invention,
By changing the display method of the cursor according to the situation,
It makes it easier for other attendees to understand where the current speaker is in a group meeting. That is, when all the people attending the meeting pay attention to the part indicated by the current speaker, it becomes easy to concentrate on the agenda and grasp the contents of the meeting.

Further, since it is always possible to confirm where the cursor is, it is possible to recognize the relative positional relationship on the screen and perform an accurate operation even when the pointing device is suddenly operated. .
