This projector can project an image on a PC onto a screen, and is very convenient for giving presentations to a large number of people, and is expected to become more popular in the future.
[0004]
[Problems to be solved by the invention]
In such a projector, various operation controls on the projector, such as switching of a projected screen, are generally performed by operating a mouse or a keyboard connected to the PC body.
[0005]
Therefore, at the presentation venue, the presenter advances the presentation while operating the mouse near the PC, or asks another person to perform the operation and asks the PC to operate the PC as the meeting progresses. The method is taken.
[0006]
However, the former method has a problem that the presenter cannot concentrate on the presentation because the presenter has to perform complicated PC operations while watching the screen and the audience alternately.
[0007]
Further, depending on the scale of the venue, the distance between the installation position of the projector and the PC and the position where the presenter stands may have to be long, and there may be a situation where the PC cannot be operated at hand. In such a case, a PC operation will be requested from another person in the end. However, if a PC operation is requested from another person, it will be necessary to secure personnel other than the presenter, and between the presenter and the operator. There is a problem that it is necessary to carefully conduct detailed meetings such as operation procedures, and if the presenter and the operator do not agree during the demonstration, smooth progress cannot be made and a satisfactory presentation cannot be performed.

In addition, in order to be able to acquire data from the network, the network connection unit 2b is provided as a presentation data input means, and by connecting the network connection unit 2b to the network, necessary presentation data is read and read. Can be held.
[0036]
FIG. 2 is a block diagram for explaining the configuration of the projector 1 and the commander 2 with a microphone in the first embodiment. The projector 1 and the commander 2 with a microphone will be described in detail with reference to FIG.
[0037]
The projector 1 includes a projector function operation unit 11, a setting / operation unit 12 that enables various settings and operations, a signal receiving unit 13, a projector control unit 16, a D / A converter 17, a speaker 18, and the like. These components are those normally provided in conventional projectors.
[0038]
The projector function operation unit 11 performs a function (such as a function of projecting an image or switching a screen) provided in the projector, and receives the image data from the projector control unit 16 and projects the image. At the same time, it receives an operation control signal from the projector control unit 16 (control signals for forward and reverse slide screens, image selection, list display, etc.) and performs corresponding operations.
[0039]
The signal receiving unit 13 receives audio data and control signals transmitted from the commander 2 with microphone, and passes the received audio data and control signals to the projector control unit 16.
[0040]
In this case, the audio data transmitted from the commander 2 with the microphone is the audio data when audio data is included in the audio data for the presenter to explain to the audience or the presentation data. In this case, the control signal transmitted from the commander with microphone 2 includes an operation control signal (which will be described later) corresponding to a command (voice command) that the presenter is currently speaking.
[0041]
The projector control unit 16 has a function of controlling the components of the entire projector 1. As a function related to the present invention, the audio data sent from the commander 2 with a microphone is output to the D / A converter 17. And a function of passing image data to be projected and an operation control signal sent from the commander 2 with a microphone to the projector function operation unit 11.
[0042]
The D / A converter 17 converts the digitized voice data into an analog signal. Here, the digitized voice data sent from the commander 2 with a microphone (sound for explanation purposes) Data) and digitized audio data included in the presentation data (in this embodiment, these audio data pass through the projector control unit 16) are D / A converted. Output from the speaker 18.
[0043]
On the other hand, the commander 2 with a microphone has an audio data output function as a function of a very general microphone, as well as a function of acquiring and holding presentation data, and an operation control signal and projection for the projector 1. A function of generating image data to be output and sound data to be output; a microphone 21, an A / D converter 22 that converts sound data from the microphone into a digital signal, a commander control unit 23, a commander operation unit 24, A signal transmission unit 25, a feature analysis unit 26, a speech recognition unit 27, a presentation data input unit 28, a presentation data storage unit 29, and the like are included.
[0044]
In this case, the presentation data input unit 28 includes a slot unit 1a and a network connection unit 2b (see FIG. 1) in which a storage medium 3 such as a memory card can be mounted.
[0045]
When the storage medium 3 such as a memory card is inserted into the slot 1a of the presentation data input unit 28, the presentation data stored in the storage medium 3 is converted into the presentation data storage unit under the control of the commander control unit 23. 29 can be read. Also, by connecting the network connection unit 2b to the network, the presentation data storage unit 29 can be read by the commander control unit 23 under the control of the commander control unit 23.
[0046]
The commander control unit 23 controls the overall components of the commander 2 with a microphone, and has the function of reading the presentation data into the presentation data storage unit 29 as described above, and further reads into the presentation data storage unit 29. Software having a function of acquiring the presentation data and generating image data to be projected and audio data to be output (digitized audio data) included in the presentation data. The image data and audio data generated by the projector control unit 23 are transmitted to the projector 1 side by the signal transmission unit 25.
[0047]
Note that software that executes a function for generating image data and audio data from presentation data is conventionally held by a PC, and generates image signals and audio data on the PC side and passes them to the projector 1. However, in the present invention, all these functions are performed on the commander 2 side with a microphone.
[0048]
The feature analysis unit 26 receives voice data (voice data A / D converted by the A / D converter 22) corresponding to the voice command of the presenter input from the microphone 21 via the commander control unit 23, and receives a voice recognition unit. 27 generates feature data used for speech recognition, and passes the result of the feature analysis to the speech recognition unit 27.
[0049]
The voice recognition unit 27 performs voice recognition by a control signal from the commander control unit 23, and the recognition result is passed to the commander control unit 23.
[0050]
As described above, the presentation data storage unit 29 stores the presentation data stored in the storage medium 3 such as a memory card or the presentation data acquired from the network. In this case, as in this embodiment, the presentation data stored in the presentation data storage unit 29 may be temporarily read, but the commander control unit 23 may be read from the storage medium 3 such as a memory card. It is also possible to read directly.
[0051]
The commander operation unit 24 has a mode switching button 24a, and by operating the mode switching button 24a, it is possible to set whether the speech sound of the presenter is output as it is or whether the speech is recognized. .
[0052]
For example, when the presenter explains the projection contents to the audience, the presenter speaks without pressing the mode switching button 24 a provided on the commander operation unit 24, and the presenter controls the operation of the projector 1. When a voice command is issued to perform the utterance, the user speaks while pressing the mode switching button 24a.
[0053]
The operation state of the mode switching button 24a is monitored by the commander control unit 23 to determine what setting is currently set. That is, a command signal indicating whether or not the mode switching button 24a is pressed is sent to the commander control unit 23, so that the commander control unit 23 can know the operation state of the mode switching button 24a.
[0054]
Thus, for example, if the user speaks without operating the mode switching button 24a, the commander control unit 23 determines that the mode switching button 24a is not operated, and the current speech voice is not a voice command (voice recognition). Therefore, the audio data is output from the signal transmission unit 25 to the projector 1 side.
[0055]
The audio data is received by the signal receiving unit 13 on the projector 1 side, and then sent to the projector control unit 16. Then, the audio data is converted into an analog signal by the D / A converter 17 and output as audio from the speaker 18.
[0056]
If the presenter speaks in a state where the mode switching button 24a is operated, the commander control unit 23 receives a control signal indicating that the mode switching button 24a is pressed, so that the speech voice of the presenter is a voice command. The voice recognition unit 27 is notified to perform voice recognition processing. As a result, the speech uttered by the presenter is sent to the feature analysis unit 19 for feature analysis, and then the speech recognition unit 27 performs speech recognition processing. Then, the recognition result is passed to the commander control unit 23.
[0057]
As described above, when the presenter speaks without pressing the mode switching button 24a, the commander 2 with a microphone functions as a normal microphone, and the presenter speaks while pressing the mode switching button 24a. In this case, the commander 2 with a microphone performs voice recognition processing for a voice command for the presenter to control the operation of the projector 1.
[0058]
In such a configuration, a specific usage example of the presentation system using the remote control device for the projector of the present invention, the operation of the projector at that time, and the like will be described. First, when a presenter makes a presentation, a storage medium 3 such as a memory card storing presentation data used for the presentation is inserted into the slot 1a (see FIG. 1) of the commander 2 with a microphone. Then, the presentation data stored in the storage medium 3 inserted in the slot 1a is read into the storage means (presentation data storage unit 29) of the commander 2 with a microphone. The presentation data can also be obtained from the network.
[0059]
Thus, when preparations are made to make a presentation, the projector 1 is installed at the presentation venue. The presenter then takes the commander 2 with a microphone, stands on the podium and starts the presentation. At this time, the projector 1 can be installed at an arbitrary position where it can be easily projected onto the projection plane as long as it can receive the signal from the commander 2 with a microphone satisfactorily, and it is not particularly necessary to install it near the presenter.
[0060]
The projector control unit 16 of the projector 1 outputs presentation data (image data to be projected and audio data to be output) sent from the commander 2 with a microphone to the projector function operating unit 11 and the A / D converter 17. .
[0061]
That is, the image data is given to the projector function operation unit 11 and projected as an image on the projection surface. The audio data is output to the D / A converter 17, converted into an analog signal, and then output from the speaker 18.
[0062]
On the other hand, the commander 2 with a microphone can perform various operation controls such as screen switching and screen selection wirelessly with respect to the projector 1 in this embodiment, and is also for explaining the projection image to the audience. Audio data can be sent.
[0063]
At this time, when explaining the projection image to the audience or the like, if the user speaks toward the commander 2 with the microphone without pressing the mode switching button 24a, the voice data is not directly recognized and transmitted as it is. After being transmitted from the unit 25 to the signal receiving unit 13 of the projector 1, it is output 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 from the speaker 18. Is output.
[0064]
Further, when the presenter sends a voice command to the projector 1, the speaker speaks while pressing the mode switching button 24 a of the commander 2 with a microphone.
[0065]
For example, it is assumed that an utterance such as “next screen” is performed as a voice command for switching the screen. 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, the voice command is recognized, and the recognition result is recognized. It understands that it is in the state of performing the operation corresponding to, that is, the voice recognition mode.
[0066]
Therefore, the voice data of the “next screen” uttered by the presenter is input to the feature analysis unit 26, subjected to feature analysis, the feature data is passed to the voice recognition unit 27, and the utterance content of the presenter is recognized, The recognition result is passed to the commander control unit 23.
[0067]
The commander control unit 23 generates an operation control signal corresponding to the recognition result, and the operation control signal is sent from the signal transmission unit 25 to the projector control unit 16 via the signal transmission unit 13 of the projector 1.
[0068]
The projector control unit 16 passes an operation control signal based on the voice recognition result sent from the commander 2 with a microphone to the projector function operation unit 11. In this case, since the recognition result is “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. Accordingly, the projector function operation unit 11 performs an operation to switch the screen to be projected to the next screen.
[0069]
Various types of voice commands can be set. For example, when the screen is advanced, as described above, “next” may be used in addition to “next screen”. Also, when returning the screen to the front, it is set to “Previous” or “Previous Screen”. Furthermore, when a specific screen is specified by skipping the screen, for example, it is possible to specify a screen number such as “what number”, and “list display” for displaying the whole on one screen. Voice commands such as
[0070]
In addition to switching the screen, you can also set the audio volume and specify the file if the presentation data prepared in the presentation data storage unit consists of several files. Various voice commands can be set.
[0071]
In order to be able to deal with such various voice commands, the commander control unit 23 needs to generate an operation control signal corresponding to the recognition result in the voice recognition unit 27. In the case of a result, what kind of operation control signal should be output may be set in advance.
[0072]
For example, for the recognition result of “next screen” or “next”, an operation control signal is generated for performing control to switch the screen to be projected next, and “previous screen” or “previous” is generated. The recognition result is set in advance so as to generate an operation control signal for performing control for returning the screen to be projected forward.
[0073]
Further, when it is desired to read out and project a specific screen data from data corresponding to each screen (referred to as screen data) stored in the presentation data storage unit 29, the screen data of which screen number is displayed. If there is a title in the screen data, even if it is data, but the screen data has a title, search for the corresponding screen data by giving the title as a voice command or by giving the characteristics of the screen data contents as a voice command Thus, the commander control unit 23 can be provided with a function that allows it to be read and projected.
[0074]
As described above, according to the first embodiment, the presentation data is read by the commander 2 with microphone and stored in the presentation data storage unit 29, and the stored presentation data is stored. Since image data to be projected and sound data to be output can be generated and output from the data, the projector 1 is connected to the PC and the image data to be projected and the output on the PC as in the past. It is not necessary to perform processing for generating sound data to be performed.
[0075]
In addition, 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. In other words, as in the past, in the command using the button operation of the wireless remote controller, as described above, if there are a lot of operation buttons, it is difficult to determine which button to press, and there are many mistakes in pressing the button. However, in the present invention, since these operations can be performed with voice, efficient operations can be performed.
[0076]
Thus, for example, when a presentation is finished and a question from an audience is received, even if it is necessary to immediately display a specific screen, the screen can be designated by voice, and thus a certain function is performed. Therefore, there is no need to perform a troublesome operation of operating a plurality of buttons in order.
[0077]
Further, when it is desired to read out and project a specific screen data from a lot of screen data stored in the presentation data storage unit 29, even if the screen data is not immediately known, it is described above. In this way, it is possible to search and project the corresponding image simply by giving the title of the screen data and the characteristics of the screen data contents as a voice command, so that necessary screen data can be read out later. This is extremely convenient when projecting.
[0078]
The presentation data input unit 28, the presentation data storage unit 29 that holds the input presentation data, and the image data to be projected and the audio data to be output from the presentation data stored in the storage unit 29. Since the software having a function capable of generating and outputting is provided on the commander 2 side with a microphone, it is one of the great features that the projector 1 can use a conventional projector almost as it is.
[0079]
[Second Embodiment]
FIG. 3 is a diagram for explaining a second embodiment of the present invention. The configuration of FIG. 3 includes this commander 2 with a microphone as a component of the remote control device for a projector according to the present invention.

[0080]
Then, a connection terminal such as a connector that can be electrically connected to the commander 2 with microphone and the microphone stand 4 (connection terminal 2t on the commander 2 side with microphone and connection terminal 4t on the microphone stand 4 side). When the microphone-equipped commander 2 is held by the microphone stand 4, the connection terminals 2t and 4t are connected to each other so that the presentation data on the storage medium 3 inserted into the slot 4a and the network connection 4b The presentation data from the network connected to can be taken into the presentation data storage unit 29 on the commander 2 with microphone.
[0081]
FIG. 4 is a block diagram showing such a configuration. As can be seen from FIG. 4, the microphone stand 4 is provided with a presentation data input unit 41 and a connection terminal 4t.
[0082]
The commander 2 with a microphone includes a microphone 21, an A / D converter 22, a commander control unit 23, a commander operation unit 24 (including a mode switching button 24a), a signal transmission unit 25, a feature analysis unit 26, and a voice recognition unit. 27, a presentation data storage unit 29, and a connection terminal 2t are provided.
[0083]
Since the projector 1 has the same configuration and functions as those described in the first embodiment, description thereof will be omitted.
[0084]
Thus, in the second embodiment, the presentation data input unit 41 is provided on the microphone stand 4 side. As a result, the slot 4a for inserting the storage medium 3 can be enlarged, so that it is mounted not only on a small storage medium such as a memory card but also on the commander 2 side with a microphone such as a floppy disk or a compact disk (CD). A slot portion for a storage medium having a shape and size that is difficult to perform can be provided, and various storage media such as a floppy disk and a CD can be used, so that the versatility is further improved.
[0085]
