The projector function operating unit 11 performs a function originally provided in the projector (such as a function of projecting an image and switching screens), receives an image signal from the projector control unit 16, and displays the image. At the same time as projecting, it receives an operation control signal (control signal for forward or reverse feed of the slide screen, image selection, list display, etc.) from the projector controller 16 and performs an operation corresponding thereto.

The signal receiving unit 13 is a commander 2 with a microphone.
It receives audio data and control signals transmitted from the device, and passes the received audio data and control signals to the projector control section 16.

The voice data transmitted from the commander 2 with a microphone includes voice commands for causing the projector 1 to perform operation control and voice data for the presenter to explain to the audience. Therefore, it is necessary to perform voice recognition for a voice command for causing the projector 1 to perform operation control, but in the present embodiment, for voice data for explaining to an audience, etc. The voice is output as it is without voice recognition.

Further, in this case, the control signal transmitted from the commander 2 with a microphone is voice data for explaining to the audience whether the voice the presenter is currently speaking is a voice command. A control signal indicating whether there is any (which will be described later) is included.

Presentation data input unit 14
In this case, the slot portion 1 into which the storage medium 3 can be mounted
a and the network connection unit 1b (see FIG. 1).

This presentation data input section 1
When the storage medium 3 such as a memory card is inserted into the slot portion 1a of No. 4, the presentation data stored in the storage medium 3 is transferred to the presentation data storage unit 1 under the control of the projector control unit 16.
5 can be read. In addition, by connecting the network connection unit 1b to the network, the projector control unit 16 controls
The presentation data existing on the network can be read into the presentation data storage unit 15.

The projector control section 16 has a function of controlling all the constituent elements of the projector 1 (which will be described later), and causes the presentation data storage section 15 as described above to read the presentation data. The function, further, obtains the presentation data read in the presentation data storage unit 15, and generates the image data to be projected and the audio data (digitized audio data) to be output included in the presentation data. It has software that has the function of The image data generated by the projector control unit 16 is sent to the projector function operation unit 11, and the audio data is output to the D / A converter 17.

The software for executing the function of generating the image data to be projected and the audio data to be output from the presentation data is conventionally possessed by the PC, and the PC generates the image data and the audio data. However, in the present invention, all of these functions are performed by the projector 1 side.

The D / A converter 17 converts the digitized voice data into an analog signal, and here, the digitized voice data sent from the commander 2 with a microphone (explained to the audience). Audio data) and digitized audio data included in the presentation data (in this embodiment, the audio data is passed through the projector control unit 16).
/ A converted and output from the speaker 18.

The feature analysis unit 19 is a commander 2 with a microphone.
A voice command (digital signal) transmitted from the voice recognition unit 20 generates feature data used for voice recognition, and the feature analysis result is passed to the voice recognition unit 20. Note that this voice command also passes through the projector control unit 16 in this embodiment.

The voice recognition unit 19 is the projector control unit 16
Voice recognition is performed by a control signal from the projector, and the recognition result is passed to the projector controller 16.

The presentation data storage unit 15 stores the presentation data stored in the storage medium 3 such as a memory card or a floppy disk, or the presentation data acquired from the network, as described above. However, in the case of a memory card, a floppy disk, or the like, the presentation data stored in them may be temporarily read into the presentation data storage unit 15 as in this embodiment. It is also possible for the projector control unit 16 to directly read from the floppy disk.

The commander 2 with a microphone not only has a function as a general microphone but also has a function of outputting a command to the projector 1 as voice data (voice command). The microphone 21 and the A / D converter are provided. 22, a commander control unit 23, a commander operation unit 24, a signal transmission unit 25, and the like.

The commander operation unit 24 has a mode switching button 24a, and by operating this mode switching button 24a, it is possible to set whether the presenter's uttered voice is output as it is or voice recognition is performed. Has become.

For example, when the presenter explains the projection contents to the audience, the commander operation unit 24
When the presenter speaks without pressing the mode switch button 24a provided in the presenter and the presenter issues a voice command for controlling the operation of the projector 1, the presenter speaks while pressing the mode switch button 24a. . The commander control unit 23 monitors the operation state of the mode switching button 24a, and transmits a control signal corresponding to the operation state from the signal transmission unit 25 to the projector 1.

Thus, for example, if the user speaks without operating the mode switching button 24a, the commander controller 23
Outputs a control signal indicating that the code switching button 24a is not operated (a control signal indicating that it is not a voice command, that is, not voice data to be voice-recognized), and the voice data is The control signal and audio data output from the signal transmission unit 25 are received by the signal reception unit 13 on the projector 1 side, and then sent to the projector control unit 16.

The projector control section 16 judges from the control signal that the sent voice data is not the data to be voice-recognized (not the voice command), and in that case, the voice data is D / A converted. It is converted into an analog signal by the device 17 and output as a sound from the speaker 18.

Also, the presenter is the mode switching button 24.
If the user speaks while operating a, the commander control unit 23 outputs a control signal indicating that the mode switching button 24a is pressed (a control signal indicating that the speech voice of the presenter is a voice command). In addition, the audio data is output from the signal transmitting unit 25, and the control signal and the audio data are received by the signal receiving unit 13 on the projector 1 side and then sent to the projector control unit 16.

The projector control unit 16 determines that the voice data sent is data to be voice-recognized (voice command) based on the control signal, and in that case, the voice data is analyzed by the feature analysis unit 19. Then, the voice recognition unit 20 performs voice recognition processing after the feature analysis is performed. Then, the recognition result is the projector control unit 1.
Passed to 6.

In this way, when the presenter speaks without pressing the mode switching button 24a, the commander 2 with a microphone functions as a normal microphone,
Further, when the presenter speaks while pressing the mode switching button 24a, the commander 2 with a microphone has a function of issuing a voice command for the presenter to control the operation of the projector 1.

A specific use example of the presentation system of the present invention having such a configuration and the operation of the projector at that time will be described. First, when the presenter gives a presentation, a storage medium 3 (here, described as a memory card), such as a memory card, a floppy disk, a CD, in which presentation data used for the presentation is stored, is inserted in the slot portion 1a of the projector 1. Plug in. And
The presentation data stored in the memory card inserted into the slot portion 1a is stored in the storage unit of the projector 1 (presentation data storage unit 1).
Read in 5). Note that the presentation data can also be obtained from the network.

When the projector 1 is thus prepared to give a presentation, the projector 1 is installed in the presentation hall. Then, the presenter holds the commander 2 with a microphone, stands on the podium, and starts the presentation. At this time,
The projector 1 can be installed at any position where the signal from the commander 2 with a microphone can be favorably received, and it is not necessary to install the projector 1 near the presenter.

Projector control unit 16 of projector 1
In response to an instruction from the commander 2 with a microphone, the presentation data is sequentially read from the presentation data storage unit 15 and data processing is performed to convert the presentation data into image data to be projected or audio data to be output. Output as image data or audio data.

Then, the image data is given to the projector function operation unit 11 and projected as an image on the projection surface. If the presentation data includes audio data, the audio data is output to the D / A converter 17 and converted into an analog signal, and then the speaker 1 is used.
It is output from 8.

On the other hand, the commander 2 with a microphone can wirelessly transmit a voice command or a voice for explaining a projected image to an audience to the projector 1 in this embodiment.

At this time, when explaining the projected image to the audience, if the user speaks to the commander 2 with a microphone without pressing the mode switching button 24a as described above, the audio data will be obtained. Is transmitted to the D / A converter 17 by the projector control unit 16, converted into an analog signal by the D / A converter 17, and then output from the speaker 18.

When the presenter sends a voice command to the projector 1, the commander 2 with a microphone is used.
Speak while pressing the mode switching button 24a.

For example, it is assumed that a voice command "next screen" is made as a voice command for switching screens. At this time, the projector control unit 1 of the projector 1
6 is a mode switch button 24 from the commander 2 with a microphone
Since a control signal indicating that a is pressed is received,
Understand that a voice command is currently uttered, and that the voice command is recognized and an operation corresponding to the recognition result is performed, that is, the voice recognition mode.

Therefore, the audio data of the "next screen" spoken by the presenter is the signal receiving unit 1 of the projector 1.
After being received at 3, the projector controller 16 inputs the feature analysis unit 19 to perform feature analysis, the feature data is passed to the voice recognition unit 20, and the utterance content of the presenter is recognized. The recognition result is sent to the projector control unit 16.

In the projector control unit 16, the voice recognition unit 2
Based on the recognition result of 0, the projector function operation unit 1
An operation control signal for 1 is generated and passed to the projector function operation unit 11. In this case, since the recognition result is the "next screen", an operation control signal is passed to the projector function operation unit 11 to switch the screen to be projected to the next screen. As a result, the projector function operation unit 11 operates to switch the screen to be projected to the next screen.

Various types of voice commands can be set. For example, when advancing the screen, as described above, in addition to the "next screen", the "next" may be simply used.
In addition, when returning the screen to the front, "previous" or "previous screen" is used. In addition, when specifying a screen that is skipped, for example, you can specify the screen number such as "No.", and you can also display voice commands such as "List display" to display the entire screen on one screen. To be able to use.

Further, in addition to screen switching, setting of audio volume, and when presentation data prepared in the presentation data storage section is composed of several files, the file is designated. You can also set various voice commands, such as making it possible.

In order to be able to deal with such various voice commands, the projector control section 16 needs to generate an operation control signal corresponding to the recognition result of the voice recognition section 20. What kind of operation control signal should be output when such a recognition result is set in advance. For example, for a recognition result of "next screen" or "next", an operation control signal for controlling to switch the screen to be projected next is generated, and the result is called "previous screen" or "previous". The recognition result is set in advance such that an operation control signal for controlling the screen to be projected back is generated.

In addition, when it is desired to read out and project a certain specific screen data from the data (referred to as screen data) stored in the presentation data storage unit 15 corresponding to each screen, what is the screen data? Even if it is the second screen data, if the screen data has a title, if the title is given as a voice command or the characteristics of the screen data contents are given as a voice command, the corresponding screen is displayed. The projector control unit 16 may have a function of searching data, reading the data, and projecting the data.

As described above, according to the first embodiment, the presentation data is read by the projector 1 and stored in the presentation data storage unit 15, and the stored presentation data is stored. Since the image data to be projected and the audio data to be output can be generated and output from the use data, the projector 1 can be connected to the PC and the image data to be projected or It is not necessary to perform a process of generating audio data to be output.

Since various operation controls such as screen switching for the projector 1 can be performed by voice commands, the presenter can easily operate the projector remotely and perform a smooth presentation. In other words, as in the past, with commands operated by buttons on the wireless remote controller, as mentioned above, if there are many operation buttons, it is difficult to decide which button to press, and there are many mistakes when pressing the buttons. However, in the present invention, since those operations can be performed by voice, efficient operations can be performed.

Thus, for example, when the presentation is over and questions from the audience are received, even when a specific screen needs to be immediately displayed,
Since the screen can be designated by voice, it is not necessary to perform the troublesome operation of operating a plurality of buttons in order to perform a certain function.

In addition, among many screen data stored in the presentation data storage unit 15,
If you want to read out a specific screen data and project it,
Even if you do not immediately know what number the screen data is, as described above, by simply giving the title of the screen data and the characteristics of the screen data content as a voice command, the corresponding image is searched and projected. Since it is also possible to do so, it becomes extremely convenient when necessary screen data is read out and projected later.

[Second Embodiment] The schematic configuration of the presentation system according to the second embodiment is also composed of a projector 1 and a commander 2 with a microphone, as in FIG. The projector 1 has a function as a projector that a conventional projector normally has, and also has a function that is conventionally performed on the PC side, that is, a function for acquiring and holding presentation data and a data for the presentation 3 And has a function of projecting it as an image (including characters) or outputting it as a voice.

That is, like the first embodiment described above,
A slot portion 1a into which a recording medium 3 such as a memory card in which presentation data is stored, a floppy disk, or a CD can be loaded is provided as a presentation data input portion 14, and a memory card and a floppy disk are provided in corresponding slot portions. , A storage medium 3 such as a CD can be inserted, and the presentation data stored in the inserted storage medium 3 can be read and held.

In order to obtain data from the network, the network connection unit 1b is provided as the presentation data input unit 14, and the network connection unit 1b is connected to the network so that necessary presentation data can be obtained. Can be read.

The configuration up to this point is the same as that of the first embodiment described above, but in the second embodiment, the point that the voice recognition function is provided on the side of the commander 2 with a microphone is used. The form is very different.

FIG. 3 shows the configuration of the presentation system when the voice recognition function is provided on the side of the commander 2 with a microphone. The same parts as those in FIG. 2 are designated by the same reference numerals.

In the case of the presentation system shown in FIG. 3, since the voice recognition function exists on the side of the commander 2 with a microphone, the microphone 21, the A / D converter 22, and the commander control provided in the commander with a microphone shown in FIG. In addition to the unit 23, the commander operation unit 24, and the signal transmission unit 25, a feature analysis unit 26 and a voice recognition unit 27 are included.

On the other hand, the projector 1 has a configuration in which the feature analysis unit 19 and the voice recognition unit 20 necessary for performing voice recognition are removed from the components shown in FIG. Further, the projector control unit 16 uses a commander with a microphone as a part of the processing content (for example, processing such as what kind of operation control signal is generated for the recognition result) performed in the first embodiment. Since it is performed by the commander control unit 23 on the second side,
The function for that part can be omitted.

In such a structure, when the presenter explains the projected image to the audience, as in the above-described embodiment, without pressing the mode switching button 24a,
When speaking into the commander 2 with a microphone, the voice data is not recognized as it is and the signal transmitting unit 25
From the D / A converter 1 after being transmitted to the signal receiving unit 13 of the projector 1 by the projector control unit 16.
7 is output to the D / A converter 17, converted into an analog signal by the D / A converter 17, and then output from the speaker 18.

When the presenter sends a voice command to the projector 1, the commander 2 with a microphone is used.
Speak while pressing the mode switching button 24a.

For example, it is assumed that an utterance such as "next screen" is made as a voice command for switching screens. At this time, the commander control unit 23 receives the control signal indicating that the mode switching button 24a is pressed, so that the voice command is currently uttered,
Understand that the voice command is recognized and the operation corresponding to the recognition result is performed, that is, the voice recognition mode is set.

Therefore, the voice data of the "next screen" spoken by the presenter is input to the feature analysis unit 26,
After the feature analysis, the feature data is passed to the voice recognition unit 27, the utterance content of the presenter is recognized, and the recognition result is passed to the commander control unit 23. Commander control unit 23
Then, generate the motion control signal corresponding to the recognition result,
The operation control signal is transmitted from the signal transmitter 25 to the projector 1
Is transmitted to the projector control unit 16 via the signal transmission unit 13.

The projector control section 16 passes the operation control signal based on the voice recognition result sent from the commander 2 with a microphone to the projector function operation section 11. In this case, since the recognition result is the "next screen", an operation control signal is passed to the projector function operation unit 11 to switch the screen to be projected to the next screen. As a result, the projector function operation unit 11 operates to switch the screen to be projected to the next screen.

In the second embodiment, like the first embodiment described above, the presentation data is read by the projector 1 side, and the image data to be projected and the audio data to be output are read from the presentation data. Since it can be generated and output, the projector 1 is connected to the PC and the
It is not necessary to perform a process of generating image data to be projected and audio data to be output.

Since various operation controls such as screen switching for the projector 1 can be performed by voice commands, the presenter can easily operate the projector 1 remotely and perform a smooth presentation. The same effect as the form is obtained.

Further, in the second embodiment, since the voice recognition function is provided on the commander side with a microphone, the function on the projector side can be reduced.

The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the present invention. For example, in the above-described first embodiment, the content of voice recognition on the projector 1 side is the voice command for operating the projector such as screen switching and screen selection sent from the commander with a microphone. Not just voice commands,
The explanation content of the presenter can be recognized by voice, and by using the recognition result, the projector control unit 16 can also generate operation control signals other than screen switching, screen selection, and the like.

For example, when the projector control unit 16 receives the recognition result of the presenter's explanation contents from the voice recognition unit 20, the projector control unit 16 understands which part of the projection screen is currently described and recognizes the part described. It is also possible to display in different colors or to display a mark indicating that part.

In the first and second embodiments described above, the speaker provided in the projector is used as the voice for explaining to the audience, but the presentation venue is wide and the projector is equipped. When the sound is hard to reach every corner of the venue with the speaker, for example, an audio device prepared separately such as an amplifier or a speaker installed in the venue can be used.

Further, in the presentation systems described in the first and second embodiments, the commander 2 with a microphone capable of inputting voice is provided in order to enable remote control by the voice uttered by the presenter. ,
In the first embodiment, the voice from the commander 2 with a microphone is recognized on the projector 1 side, and operation control is performed according to the result of the voice recognition. In the second embodiment, the commander 2 with a microphone is recognized. It is said that voice recognition is performed and a control signal corresponding to the recognition result is transmitted to the projector 1 side to perform operation control corresponding to the control signal on the projector 1 side.
In each case, the example in which the remote operation is possible by voice has been described, but it goes without saying that not only the voice but also the remote operation by the conventional operation button may be used together.

That is, the commander 2 with a microphone is provided with operation buttons corresponding to various operation controls that enable remote operation of the projector 1 so that operation can be controlled by voice and operation by operation buttons. Be controllable. As a result, for example, when the operation control by voice is not properly performed for some reason,
Since remote control by the operation button is also possible, it is possible to make it more convenient.

Further, in each of the above-described embodiments, the voice data and the control signal are sent from the commander 2 with a microphone to the projector 1 wirelessly, but it is not wireless but wired. Of course, it can be realized. This can be realized by providing the projector 1 with a connector or the like for connecting the commander 2 with a microphone.

The projector used in the presentation system of the present invention is not limited to the projection display type projector, and a wide range of projectors such as a rear display type projector can be used regardless of the image display format.

[0096]

As described above, according to the present invention, the presentation data can be read by the projector, and the image data and the audio data to be projected can be generated and output from the presentation data. It becomes unnecessary to connect the projector to the PC and perform an operation of generating image data and audio data on the PC as in the conventional case. In addition, since various operations such as screen switching for the projector can be remotely controlled by voice, a smooth presentation can be performed.

Further, as described above, in the conventional command by operating the buttons of the wireless remote controller, as described above, when there are many operation buttons, it is difficult to decide which button should be pressed, and many buttons are erroneously pressed. Although there is a problem that a smooth presentation cannot be performed due to being distracted by the operations, in the present invention, since those operations can be performed by voice, efficient operations can be performed. This allows a user to perform a certain function because the screen can be specified by voice even when a certain screen needs to be displayed immediately, for example, when the presentation is finished and questions are received from the audience. Therefore, it is not necessary to perform the troublesome operation of operating a plurality of buttons in order.
