Abstract

<P>PROBLEM TO BE SOLVED: To provide a presentation system capable of being remotely operated by means of a portable remote operating means. <P>SOLUTION: A projector 1 projects image data stored in a host PC 5 onto a screen 2 to form an image 3 with the use of software installed in the host PC, and the software is operated by a remote controller 6. The remote controller 6 is provided with an interface such as a track ball and a laser pointer for emitting laser beams 8, and communicates with a receiver 7 by radio such as IEEE802. 11, Bluetooth and an infrared ray. <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a presentation system that can be remotely operated.
[0002]
[Prior art]
Conventionally, when a presentation is performed by projecting an image on a screen using a projector or the like, a presenter and a person who operates the projector to switch the image on the screen are performed by two people. The method of giving a presentation is adopted. However, in the former case, it is difficult to explain the presenter of the presentation and the timing of switching the video, and in the latter case, there is a problem that it is necessary to move between the projector and the screen when pointing to the video on the screen.
[0003]
In recent years, there is a case where a laptop-type personal computer is connected to a projector to give a presentation. However, the above-mentioned problem and a space for placing the personal computer beside the presenter are required, and the range of the presenter's action is limited, and performance is poor. I couldn't get out of the traditional presentation style.
[0004]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a remote control presentation system which can smoothly perform remote control of video switching on a screen and point out a main part by a portable remote control means.
[0005]
[Means for Solving the Problems]
The present invention has been made in order to solve the above-described problems, and includes a projection unit that projects an image on a screen, a control unit that controls the projection unit, and a remote operation unit that remotely controls the control unit by wireless. Wherein the remote control means comprises a laser pointer.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a schematic explanatory view showing one embodiment of the present invention. Reference numeral 1 denotes a projector that projects an image 3 on a screen 2 and is connected to a host PC 5 via a communication cable 4 such as a USB. Reference numeral 6 denotes a remote controller with a built-in laser pointer, and reference numeral 7 denotes a PC card type receiver connected to a PC card slot of the host PC.
[0007]
The remote controller 6 has a built-in interface such as a trackball, and communicates with the receiver 7 by wireless such as IEEE 802.11, Bluetooth or infrared. The image 3 projected on the screen 2 is projected from image data stored in the host PC 5 by the projector 1 by software installed in the host PC 5, and the software is operated by the remote controller 6. Since the remote controller 6 has a built-in laser pointer, it is possible to switch the image 3 while pointing the image 3 with the laser light 8.
[0008]
In the above embodiment, the projector 1 and the host PC 5 are connected by wire, but it is needless to say that the projector 1 and the host PC 5 may be wireless.
[0009]
【The invention's effect】
As described above, according to the present invention, the image on the screen 2 can be switched by the portable operation device, that is, the remote controller 6, so that the presenter can give a presentation at an arbitrary position, and the presenter's action range Can freely move around in the venue, so that the presentation effect can be improved.
