Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a presentation system including a remote controller for performing key input of a personal computer (PC) wirelessly and peripheral devices thereof. In particular, the present invention relates to a wireless remote controller for facilitating switching of slides by remote control when used by a performer in a presentation or the like.

[0002]

2. Description of the Related Art In recent years, the number of opportunities to use a projector connected to a PC in presentations such as conference presentations has been increasing dramatically. This uses presentation software installed in a PC. Such a presentation system using a combination of a PC and a projector is more convincing to the audience, the time required for preparing slides in advance, or two slides created once, compared with the conventional mainstream OHP projectors and sheets. Although it has very good features in terms of subsequent processing, there are many problems that many performers feel inconvenience in actual presentations.

[0003] The performer preliminarily prepares presentation software files (data for switching screens in slide format)
In the actual production, either a third party is requested to operate the PC and the slide screen is turned on, or the presentation is performed by operating a pointing device such as a mouse or a keyboard by the PC by yourself. Will be selected. However, in the former case, in addition to the necessity of one or more dedicated operators, it takes time to perform a prior contact between the performer and the PC operator, and yet the presentation in the actual production proceeds smoothly. Often not. In the latter case, on the other hand, the performer must perform more complicated PC operations while looking at the screen and the audience. It often happens that you cannot give a satisfactory presentation, such as spending your time unnecessarily.
Since various attempts have been made to improve such problems, some typical known examples will be described below.

JP-A-8-179880, JP-A-10-1
In 12892, a wireless remote controller is used, which is provided with the function of a PC mouse, so that the performer can switch the slide screen from the stage by remote control. These have been further developed and disclosed in
3103, Japanese Patent Application Laid-Open No. H11-143634 (Japanese Patent Application Laid-Open No. H11-143634) proposes a system in which a series of keyboard operations, including a mouse function, are recorded (registered) on a remote controller so that a performer can directly control presentation software directly. According to 8-3343482, in addition to these, the performer can remotely control even the adjustment of the projector (such as focus and zoom of the lens).

If the present invention is not limited to the application of the presentation system, for example, see JP-A-6-28
4469, Japanese Patent Application Laid-Open No. 10-124222, a proposal to incorporate the functions of a keyboard and a mouse into a remote control of a television or a video, and Japanese Patent Application Laid-Open No. 62-168218,
No. 5,095,526 discloses a system using a desktop wireless keyboard having some functions of a keyboard as an auxiliary input device. All of these have a technical common point in that a PC is controlled by remote control.

In these remote operations including the above-mentioned known technology, infrared rays similar to those of televisions and video remote controls mainly used in ordinary homes are often used as communication means.

[0007]

However, all of the above-mentioned conventional examples have serious problems that become apparent. The issues that need to be solved are pointed out below.

[0008] As introduced in the prior art described above, the PC
Aiming to smoothly perform a presentation using a combination of a projector and a projector, means have been proposed in which a performer can remotely control a PC or a projector by using a remote controller or the like. However, JP-A-8-17
9880 and Japanese Patent Application Laid-Open No. H10-112892 require a performer to operate a remote control having a function equivalent to a mouse which is a representative of a pointing device. This is easy to see when we demonstrate,
It is very inconvenient to use, and particularly when performing a presentation in a state where the performer stands up, it is difficult to smoothly perform an operation that requires positional accuracy of the pointer on the screen with the remote control mouse. Furthermore, there are many problems such as the fact that only the operation of the remote control mouse is distracted and the concentration of the performer is lost, and a satisfactory presentation cannot be made. Also, Japanese Patent Application Laid-Open
The method at 0-112892 only allows the slide to be advanced. It is clear that if the performer could not return the slide, it would not be practical.

JP-A-10-283103, JP-A-11-
143634, JP-A-8-334832, JP-A-10-
In 124222 and JP-A-6-284469, all functions considered necessary for presentations including the operation of the PC are incorporated into the system without any context, so that the functions become too multifunctional and provided in the remote control. The number of switches and buttons is very large, and it is very difficult for a performer to use them. In addition, the size of the remote control inevitably increases, which is not practical in terms of portability. Furthermore, the function that can be operated with the remote controller must be recorded (registered), and the purpose is to provide versatility. On the contrary, the complicated setting is required, and the usability is greatly deteriorated. There is a problem that. To further add to the catastrophic drawback, these remote controls and their peripheral systems are very expensive to manufacture.

JP-A-62-168218, Japanese Utility Model Laid-Open No. 5-0
In 59526, the presentation environment is not premised. However, since the remote control device has basically the same structure as the keyboard, the remote control device cannot be carried around with a palm as a remote control, and is used by placing it on a desk. There must be. Therefore, there is a problem that the presenter cannot carry and operate the presenter while moving within a certain range in a presentation.

The present invention has been made as a result of intensive investigation and research in order to solve all of these problems. In other words, in a presentation where a PC and a projector are combined, the main purpose is to make it easy for the performer to easily perform basic operations necessary for presentations such as slide screen advancement, and to be excellent in portability and versatility. It is another object of the present invention to provide a presentation system including a new wireless remote controller and its peripheral devices which can be manufactured at low cost.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in more detail with reference to examples.

(Embodiment 1) FIG. 1 shows a wireless remote controller of the present invention and a presentation system of the present invention including the same. When the transmission buttons (buttons 101 to 111) provided on the remote controller 1 are pressed, different infrared signals corresponding to the respective buttons are transmitted from the infrared LED 2. For example, when the button 104 of the remote controller 1 is pressed, an infrared signal is transmitted from the infrared LED 2. This is received by the photodiode of the receiver 4 of the receiver 3 and converted by the converter 5 into a signal corresponding to an output signal generated when the “→” key on the keyboard is depressed. This output signal is input to the PC 7 via the keyboard cable 6.

As a test, a word processor operating on the PC 7 was started, and the above-mentioned button 104 was continuously pressed three times. Following this, it was confirmed that the caret (flashing cursor) projected and displayed on the screen 9 from the monitor of the PC 7 and the projector 8 moved three characters to the right. Also, button 10 on remote control 1
Pressing 1 once moves the caret one character to the left, then presses the button 111 to start a new line and move the caret to the beginning (left end) of the next line.

Similarly, when the operation of some other remote control buttons was examined, it was confirmed that the key output set for each of them was performed through the converter 5.
Table 1 shows the relationship between the buttons 101 to 111, the corresponding receivers, and the key output signals by the character symbols displayed on the key tops of the keyboard.

In this embodiment, the buttons corresponding to the eleven types of key outputs listed in Table 1 are provided on the remote controller. However, the present invention is not limited to this, and can be selected from the eleven types according to the purpose. It is only necessary to provide a button corresponding to at least one or more key outputs. Further, although infrared rays are used here as the wireless transmission means, the invention is not limited to this. An electromagnetic wave of another frequency band may be used, or a means other than the electromagnetic wave, for example, a sound wave (including an ultrasonic wave or the like) introduced in a later-described embodiment 8 may be used.

[0020]

[Table 1]

(Embodiment 2) As shown in FIG. 2, the function of the receiver 3 shown in FIG. 1, that is, the receiving unit 4 and the converting unit 5 are incorporated in the housing of the PC 7.

When a function confirmation experiment was performed, it was confirmed that the operation was completely the same as that of the system shown in the first embodiment, and that a radio signal from a remote controller could be converted into a key output signal. By integrating the receiver and the PC in this way, convenience in carrying, installing, and using is improved. The keyboard cable 6 of FIG. 1 is no longer necessary. In addition, the receiver 3
Since the case was unnecessary, the manufacturing cost of the system could be reduced.

(Embodiment 3) Here, as shown in FIG. 3, the functions of the receiver 3 of FIG. 1, that is, the receiver 4 and the converter 5 are incorporated in the housing of the projector 8. The converted key output signal is sent to the PC 7 via the keyboard cable 66 for newly connecting the PC 7 and the projector 8 and processed. The function is completely the same as that of the system shown in the first embodiment. As a result of an operation experiment, it was confirmed that a wireless signal from a remote controller could be converted into a key output signal.

In this embodiment, the function of the projector main body is improved.

(Embodiment 4) In the case of a presentation, in order to direct the eyes of the audience to a desired position on the screen,
In recent years, portable laser pointers have been increasingly used. Based on this situation, in the present embodiment, a new remote controller 11 shown in FIG. Here, the buttons for remotely controlling the PC are:
Limited to “←”, “↓”, “↑”, “→” (101-104). The reason is that in the presentation software used in the presentation experiment described below, the operations of “forward” and “return” on the slide screen correspond to “→” and “←” on the keyboard, respectively, and the operation is easy. It is to make it. The function of the remote controller 11 will be described. When the power button 41 is turned on and the laser oscillation switch 42 is pressed down, the visible laser emits light and functions as a pointer at the time of presentation. Button 10
Reference numerals 1 to 104 correspond to the key operations described above, and can remotely control the PC.

A presentation experiment was performed using the remote controller 11 of the present invention. 10 performers (1 to 1 performers)
At 0), a presentation was made using ten slides for a duration of 15 minutes while the remote controller 11 of the present invention was operated by a portable device. Table 2 shows the results of measuring the time required for the actual presentation of each performer.

On the other hand, the same ten presentations were carried out by having the same performer carry the commercially available laser pointer without using the remote controller 11 of the present invention and switching the slides by a dedicated PC operator. Experiment 1
Went as. Here we also measured the actual presentation time of each performer. The results are also shown in Table 2. As is clear from Table 2, when the remote controller 11 of the present invention was used, all of the performers could finish the presentation accurately within almost the allotted time, whereas in the comparative experiment 1, the performers were able to finish the presentation. It was found that the time required for the presentation was highly variable. Especially in the case of performer 3, there is a scene where three slides are returned on the way,
In Comparative Experiment 1, the coordination between the PC operator and the performer 3 was poor and lingering, and the time was greatly exceeded.

[0028]

[Table 2]

Embodiment 5 In this embodiment, a presentation experiment was performed using the remote controller 11 (FIG. 4) of the present invention shown in Embodiment 4. Ten performers (performers 1 to 10) were given a presentation for 15 minutes with 10 slides while holding the remote controller 11 of the present invention. Table 3 shows the results of measuring the time required for each performer's actual presentation.

On the other hand, there is a method in which the same 10 performers carry a commercially available laser pointer without using the remote controller 11 of the present invention, and the performers themselves can switch slides by operating a keyboard connected to a PC. The same presentation as above was performed as Comparative Experiment 2. Here we also measured the actual presentation time of each performer. Table 3 shows the results. As is clear from Table 3, when the remote controller 11 of the present invention was used, all of the performers could finish the presentation accurately within almost the allotted time, whereas in the comparative experiment 2, the performers between the performers did not. It was found that the time required for the presentation was highly variable. Particularly, in the case of the performer 1, in the comparative experiment 2, when switching the first slide screen, the player accidentally hit a key on the keyboard not related to the slide feed. As a result, the presentation software stopped working, and we spent a lot of time restoring it. Such an operation error is often seen in the related art because the line-of-sight movement distance between the screen of the performer and the keyboard is large, and the keyboard has a large number of keys. Such an erroneous operation did not occur at all with the portable remote controller 11 of the present invention, which can be easily operated while keeping the line of sight at the screen.

[0031]

[Table 3]

(Embodiment 6) In presentations, wireless microphones are frequently used. In this embodiment, a remote controller of the present invention having a portable wireless microphone function was manufactured. FIG. 5 shows an outline of the presentation system. Buttons 101 and 104 corresponding to “←” and “→” on the keyboard are provided on the wireless remote controller 51 of the present invention.
Is provided. When these buttons are pressed, a signal is transmitted using a carrier wave in the same frequency band as the wireless microphone, and after being received by the antenna 52 of the receiver 3, the signal is converted into a key output signal by the converter 5 and sent to the PC 7.

A presentation was actually given using the remote controller 51 of the present invention. In the presentation software used in this embodiment, the slide screen feed,
Since the return operation can be performed by using “←” and “→” on the keyboard, the remote controller 51 of the present invention can perform operations corresponding to these operations. The performer uses the remote control 51 as a wireless microphone.
By using the buttons 101 and 104 while using, a smooth presentation could be performed while switching slides as desired.

(Embodiment 7) In recent years, the possession rate of mobile phones has been dramatically increased, and mobile phones themselves are being incorporated with more and more functions as small information terminals. Focusing on this, in the present embodiment, the mobile phone function and the remote control function of the present invention described so far are combined into one housing, and a wireless remote control 61 as shown in FIG. 6 is manufactured. The switch 62 can switch between the mobile phone function and the remote control function for presentation. Also, the numeral keys of the mobile phone, “2”, “4”, “6”, and “8” are 10 in FIG.
3, 101, 104, and 102. These four numeric keys correspond to “↑”, “←”,
Assigned to correspond to "→" and "↓" key operations.

The operation of the wireless remote controller 61 of the present invention and the presentation system shown in FIG. 6 using the same can be confirmed.

(Embodiment 8) In the embodiments described so far, signals transmitted from the wireless remote controller of the present invention use electromagnetic waves such as infrared rays as a carrier. In this embodiment, a system using sound waves will be described.

FIG. 7 shows an outline of the presentation system. As in the sixth embodiment, the remote controller 71 has a microphone function, and the buttons 101 and 104 are assigned functions corresponding to “←” and “→” on the keyboard, respectively. When the button 101 is pressed, the frequency is 1 kilohertz (KHz) from the speaker 73 via the wireless microphone receiver 72.
Is output for 0.1 seconds. This is received by the microphone 74 of the receiver 3, converted by the converter 5 into a key output signal corresponding to “←”, and sent to the PC 7. On the other hand, when the button 104 is pressed, a sound wave having a frequency of 2 kilohertz (KHz) is transmitted from the speaker 73 via the wireless microphone receiver 72 to a frequency of 0.2 kHz.
Output for 1 second. This is received by the microphone 74 of the receiver 3, converted by the converter 5 into a key output signal corresponding to “→”, and sent to the PC 7.

When the operation of the presentation software was confirmed in this system in the same manner as in Example 6, the slides could be switched by remote control without any problem. The sound wave here is not limited to the audible range. In a broad sense, it includes ultrasonic waves. Further, in the present embodiment, a sound wave having a different frequency is generated from the speaker 73 for each button (101 or the like) on the remote controller, but other methods such as changing the pulse sequence of the output sound wave for each button may be used. Anything that can be identified and separated on the machine 3 side may be used.

[0039]

According to the conventional wireless remote controller for presentation using a PC, the main focus is only on enhancing its functions. Therefore, the number of buttons and switches is large and the operation is complicated. The actor was only confused.

According to the present invention, the transmitted data from the wireless remote control only corresponds to a small number of specific PC keyboard inputs. The specific keyboard input is represented by key operations such as “←”, “→”, “↑”, “↓”, and “Esc”. These are, as proved in the previous embodiment, very frequently used operations such as switching slide screens in general presentation software, and Windows (Windows).
Is a basic software (such as Microsoft Corporation trademark)
S) is sufficient to operate. In actual presentations, adding more functionality to the wireless remote control proved useless.

With the presentation system of the present invention, it has become possible to dramatically improve the efficiency of presentation using a PC and a projector. On the other hand, the wireless remote controller of the present invention is much easier to operate than conventional ones, and is small and light. As shown in the embodiment, by adding a microphone and a laser pointer function to this, a smoother presentation was made possible. Since the mechanism is very simple, the production cost can be greatly reduced, and the effect brought about is extremely large, such as that sufficient consideration is given to environmental problems such as effective use of resources.
