Accordingly, it is possible to perform a remote operation using the mobile phone 1 and perform an operation from the operation unit 32 of the notebook personal computer 2 main body as necessary.

  Alternatively, the function switching unit 36 receives the remote operation instruction signal, and locks the instruction personal computer 2 so as not to accept the instruction signal from the operation unit 32 while the notebook computer 2 executes a function based on the instruction signal. It is good. Thereby, while the operation from the mobile phone 1 is being performed, the input for the normal operation by the operation unit 32 can be invalidated, and the remote operation from the mobile phone 1 can be smoothly advanced. . In addition, when the remote operation by the mobile phone 1 is finished, it is only necessary to detect that the transmission of the remote operation instruction signal from the mobile phone 1 is interrupted and release the lock.

  The mouse pointer control unit 37 controls the mouse pointer 27 displayed on the display unit 34 while the application software for the presentation function is activated. The control related to the mouse pointer is, for example, changing (moving) the display position of the mouse pointer 27 and changing the shape, size, color, etc. of the mouse pointer 27. These functions are used for the purpose of pointing, for example, when the presenter wants to pay attention to a certain part of the slide when the slide of the presentation is displayed on the display unit.

  The slide presentation processing unit 39 performs processing for starting and ending a slide (file expansion) and for moving the slide page forward and backward while the application software for the presentation function is running.

  The video signal output unit 38 is a video signal for causing the display unit 34 to display the results of the processing performed by the function execution units (the mouse pointer control unit 37, the slide presentation processing unit 39, and the function execution unit 40). Is received from each unit and output to the display unit 34 as a video signal.

  In the present embodiment, as shown in FIG. 6, the notebook computer 2 may further include a communication unit (transmission means) 35. In this case, the video signal output from the video signal output unit 38 can be supplied to the communication unit 35. As a result, the video signal can be transmitted to another device outside the notebook computer 2 (for example, a video display device such as a projector). For example, the same video as that displayed on the display unit 34 is displayed on the video. It is also possible to display on the display unit of the display device.

  As described above, according to the configuration of the communication terminal device and the information processing device, the communication terminal device having the original purpose of use and function is used as a remote control capable of remotely operating an external information processing device. It becomes possible. Then, a wireless communication remote control system capable of remotely operating the information processing device with the communication terminal device by connecting them so as to enable wireless communication using a wireless communication technology such as Bluetooth is provided. It becomes possible.

  In addition, although Bluetooth was employ | adopted in this Embodiment about the radio | wireless communication network 5 (FIG. 2) which enables each communication terminal device to perform radio | wireless communication, it is not limited to this. Although the range of use is limited as compared with Bluetooth, IrDA (Infrared Data Association) is an example of another wireless communication technology.

  IrDA is a standard for infrared communication defined as a technical specification for performing short-distance data communication using infrared rays. If the installation distance between the communication terminal devices is limited to about 1 m, which is a communicable distance, substantially the same effect as the present embodiment can be obtained.

Next, a case where the wireless communication remote control system 10 of the present invention described so far is applied to a presentation system (video display system) 100 that performs a presentation by connecting a notebook computer 2 to a projector will be described as an example. 7 for explanation.
[Outline of Presentation System]
FIG. 7 is a diagram showing a schematic configuration when the wireless communication remote control system 10 (FIG. 2) according to the present embodiment is applied to the presentation system 100.

  As shown in FIG. 7, the presentation system 100 includes a notebook computer 2 that generates a presentation video signal and a mobile phone 1 for remotely operating the notebook computer 2 and a video output from the notebook computer 2. A projector (video display device) 3 that receives the signal and enlarges and projects it as an optical video signal, and a screen 4 that receives the video signal projected by the projector 3 and displays it as an image are included.

  The notebook personal computer 2 and the projector 3 can communicate with each other via a communication path 6, and any communication technology including wireless and wired communication may be applied to the communication path 6.

  Here, for the technique from the output of the video signal from the notebook computer 2 until the video is projected on the screen 4, for example, the technique described in Patent Document 1 is applied, and detailed description thereof is omitted here. To do.

  As described above, by applying the wireless communication remote control system 10 of the present invention to the presentation system 100, for example, the position of the mouse pointer 27 displayed on the display unit 34 of the notebook computer 2 using the mobile phone 1. Can be arbitrarily changed within the display area of the display unit 34. Accordingly, the mouse pointer 27 projected on the screen 4 can be arbitrarily moved, and the mobile phone 1 can be used like a laser pointer used in a presentation [mouse pointer control function (symbol image display control function)]. .

  In addition, using the mobile phone 1 as a remote control for the notebook computer 2, it is possible to start and end slides stored in the notebook computer 2, and to advance or return the slide page. [Slide presentation function (data file page image display control function)].

From the above, when the presenter makes a presentation at a position away from the laptop computer, the presentation can be performed smoothly so that the slide can be expanded and the point of interest can be pointed out without returning to the position where the laptop computer can be operated. It is possible to provide a presentation system 100 capable of performing
[Embodiment-Presentation System]
In the presentation system 100 of FIG. 7, the case where the notebook computer 2 executes the above two functions from the mobile phone 1 is described with reference to FIGS. 10A and 10B and FIGS. This will be specifically described below. Here again, the examples shown in FIGS. 4 and 5 are used.

  First, in order to handle the mobile phone 1 as a remote controller, an operation of switching the state of the mobile phone 1 that functions as a normal mobile phone to the mobile phone 1 (presentation mode) that functions as a remote controller of the notebook computer 2 is performed. . This operation can be realized in the same manner as when the user starts an application from a menu screen, for example. FIG. 10A shows a specific example of a GUI (Graphical User Interface) screen at that time.

  Alternatively, another input instruction key (not shown) may be provided on the mobile phone 1 and the mobile phone 1 may be changed to the presentation mode by pressing the key.

  As described above, when the presentation mode is activated from the mobile phone 1, the screen displayed on the display unit 18 of the mobile phone 1 changes to the menu screen shown in FIG.

  FIG. 10B shows a specific example of an execution screen displayed on the display unit 18 when the mobile phone 1 is in the presentation mode (that is, when the remote operation instruction signal generation unit 16 in FIG. 1 is activated). FIG. The list displayed on the display unit 18 indicates to the user which key can be pressed to operate the notebook computer 2 when the user handles the mobile phone 1 as a remote control of the notebook computer 2. belongs to. Here, it corresponds to the above-described example of the instruction signal correspondence list 7 (FIG. 5).

  Thus, for example, the user can move the mouse pointer 27 (FIG. 7) upward by pressing the top of the cross key (key U in FIG. 4), and the next of the slide by pressing the “#” key. Understand that the page can be displayed.

  Next, in the flowchart of FIGS. 8 and 9, the processing flow of each device from when the operation unit 12 of the mobile phone 1 is pressed during the presentation mode to when the video signal is output from the notebook computer 2 is shown in the flowcharts of FIGS. 8 and 9. Each will be described with reference to FIGS. 1 and 6. Here, a case where the user presses the key U in FIG. 4 will be described.

  FIG. 8 is a flowchart showing a processing flow of the mobile phone 1 from when the operation unit 12 of the mobile phone 1 shown in FIG. 1 is pressed until a remote operation instruction signal for remotely operating the notebook computer 2 is output. It is.

  The mobile phone 1 is in a state of accepting any key input of the operation unit 12 from the user (S101). When the key U shown in FIG. 4 is pressed from the operation unit 12, an instruction signal (instruction signal U of the key U) is pressed. ) Is generated and input to the function switching unit 15 (YES in S101). Next, the function switching unit 15 determines whether or not the apparatus main body is in the presentation mode (S102), and if it is in the presentation mode, supplies the received instruction signal U to the remote operation instruction signal generating unit 16 (S103). ).

  Next, the remote operation instruction signal generation unit 16 refers to the instruction signal correspondence list 7 in the memory 13, and functions identification information ("mouse" from FIG. 5) associated with the instruction signal U and the remote operation instruction signal (FIG. 5). The remote operation instruction signal to be transmitted is generated ("Moving the mouse pointer upward") (S104). The generated remote operation instruction signal is transmitted to the notebook computer 2 using Bluetooth by the wireless communication unit 14 (S105).

  When it is determined in S102 that the mobile phone 1 is not in the presentation mode, the instruction signal U is displayed in accordance with the operation state of the mobile phone 1 detected by the function switching unit 15 at that time. It is supplied to one of the function execution units 17 (S106), an appropriate function is executed (S107), and the process is terminated.

  FIG. 9 is a flowchart showing a processing flow of the notebook computer 2 from when the remote operation instruction signal transmitted by the above-described flow is received by the notebook computer 2 shown in FIG. 6 until it is output as a video signal. .

  The notebook computer 2 is in a state of accepting any instruction signal from the wireless communication unit 31 or the operation unit 32 (S201), and when the instruction signal is received via the wireless communication unit 31, it is input to the function switching unit 36. (YES in S201). Next, the function switching unit 36 analyzes the input instruction signal and determines whether or not it is a remote operation instruction signal from the mobile phone 1 (S202).

  If it is determined in S202 that the instruction signal is a remote operation instruction signal, then the function switching unit 36 performs (A) mouse pointer control from the function identification information included in the received remote operation instruction signal. It is determined whether the instruction signal relates to a function or (B) an instruction signal related to a slide presentation function (S203). When it is determined that the function identification information is “mouse” (A in S203), the function switching unit 36 supplies the received remote operation instruction signal to the mouse pointer control unit 37 (S204).

  Subsequently, upon receiving the remote operation instruction signal, the mouse pointer control unit 37 performs a mouse pointer control process (S205). More specifically, since the remote operation instruction signal indicates “move the mouse pointer upward”, a process of moving the mouse pointer 27 upward from the current position is performed, and the result is displayed as a video signal output unit. 38.

  The video signal output unit 38 outputs the resultant signal supplied from the mouse pointer control unit 37 to the communication unit 35 as a video signal (S206). Subsequently, the communication unit 35 transmits the received video signal to the projector 3 via the communication path 6 in FIG. 7 (S207).

  As a result, the mouse pointer 27 displayed on the screen 4 moves upward. If the video signal is output to the display unit 34 of the notebook computer 2 in S206, the mouse pointer 27 (FIG. 7) displayed in the display unit 34 moves upward.

  On the other hand, when it is determined that the function identification information is “slide” (B in S203) (for example, when the “#” key of the mobile phone 1 is pressed (see FIGS. 4 and 5)) The switching unit 36 supplies the received remote operation instruction signal to the slide presentation processing unit 39 (S208).

  Subsequently, when receiving the remote operation instruction signal, the slide presentation processing unit 39 performs a slide presentation process (S209). More specifically, since the remote operation instruction signal (“#” key) indicates “present next page” from FIG. 5, it is currently displayed on the display unit 34 (and screen 4) of FIG. A process of displaying the next page of the slide being performed is performed, and the result is supplied to the video signal output unit 38. Since the subsequent processing (S206, S207) has already been described, it is omitted here.

In S202, if the function switching unit 36 determines that the input instruction signal is not a remote operation instruction signal from the mobile phone 1, the instruction signal is the operation of the notebook computer 2 detected by the function switching unit 36. Depending on the state, the function is supplied to one of the corresponding function execution units 40 (S210). Subsequently, each function execution unit 40 that has received the instruction signal executes an appropriate function indicated by the instruction signal (S211), and ends the process.
[Other pointer control functions]
In addition to the function of moving the position of the mouse pointer 27 exemplified in the description of the flowchart, the mouse pointer control unit 37 shown in FIG. 6 (i) changes the shape of the mouse pointer 27, (ii) 4 has a function of changing the size of the mouse pointer 27, and (iii) changing the color of the mouse pointer 27. Each key of the operation unit 12 shown in FIG. 4 corresponding to these functions is pressed. In this case, each function of the corresponding notebook personal computer 2 is executed through the above-described flow, and the result is reflected on the screen 4 as shown in FIGS. FIG. 11A is a diagram illustrating an example of a display screen projected on the screen 4 at a certain point in the presentation system 100.

(I) Changing the shape of the mouse pointer 27 FIG. 11B shows an example of the display screen after the “2” key of the operation unit 12 of FIG. 4 is pressed from the state of FIG. . Since the “2” key corresponds to the remote operation instruction “change the shape of the mouse pointer to a circle” from FIG. 5, the shape of the mouse pointer 27 is changed to a circle. This is used when the range to be shown is not a point but a certain area.

(Ii) Changing the size of the mouse pointer 27 FIG. 11C shows an example of the display screen after the “4” key of the operation unit 12 in FIG. 4 is pressed from the state of FIG. Show. Since the “4” key corresponds to the remote operation instruction “mouse pointer size-change to large” from FIG. 5, the mouse pointer 27 is enlarged. This is used when the range to be shown is wider or when the pointer to be pointed out is more conspicuous.

(Iii) Changing the color of the mouse pointer 27 FIG. 11D shows an example of the display screen after the “9” key of the operation unit 12 of FIG. 4 is pressed from the state of FIG. 11C. . Since the “9” key corresponds to the remote operation instruction “mouse pointer color → change to white” from FIG. 5, the color of the mouse pointer 27 is changed to white. This is used to make the mouse pointer 27 stand out when the slide background is changed from whitish to blackish.

(Iv) Others Although not shown here, if the mobile phone 1 is provided with a lateral side button and the cross key (U, D, R, L) is pressed while pressing the lateral side button, the mouse pointer 27 The direction of the arrow may be changed.
[Other slide presentation functions]
In addition to the function of displaying the next page of the currently displayed slide as exemplified above, the slide presentation processing unit 39 (i) starts (ends) the slide, and (ii) 4) has a function of presenting the previous page of the slide, and when each key of the operation unit 12 of FIG. 4 corresponding to these functions is pressed, the corresponding notebook personal computer 2 goes through the above-described flow. Each function is executed and the result is reflected on the screen 4.

  For example, when the “0” key of the operation unit 12 in FIG. 4 is pressed in a state in which data of a certain presentation is selected in the notebook computer 2, the slide of the selected presentation is started, When the “0” key is pressed again while the slide is displayed, the slide can be closed.

  Alternatively, when the “*” key is pressed, the page immediately before the currently displayed slide may be displayed.

  So far, the processing flow of each device (the mobile phone 1 and the notebook personal computer 2) when the wireless communication remote operation system 10 is applied to the presentation system 100 has been described using specific examples.

  According to the above-described configuration, the position of the mouse pointer 27 displayed on the display unit 34 of the notebook computer 2 can be arbitrarily changed within the display area of the display unit 34 using the mobile phone 1. Therefore, the mouse pointer 27 projected on the screen 4 can be arbitrarily moved, and the mobile phone 1 can be used like a laser pointer used in a presentation.

  In addition, using the mobile phone 1 as a remote control for the notebook computer 2, it is possible to start and end slides stored in the notebook computer 2, and to advance or return the slide page. It becomes.

  From the above, when the presenter makes a presentation at a position away from the laptop computer, the presentation can be performed smoothly so that the slide can be expanded and the point of interest can be pointed out without returning to the position where the laptop computer can be operated. It is possible to provide a presentation system 100 capable of performing
