Description

Portable apparatus for presenting

The present invention relates to a presentation device, and more particularly, to a portable presentation device for receiving and storing data from a computer and outputting the data to an external display device.

In general, presentation refers to the presentation of research contents, the presentation of a plan or business description, the presentation at a seminar, etc., and the presentation of a claim or opinion to a large number of people.

If you need to provide a large number of people with the materials you need for your presentation, use handouts, use briefing charts, slider projectors, and OHP. In recent years, a lot of projectors are used which are simple to use and have various functions. A projector is a device that converts certain screen data into an image that can be recognized by people, and is commonly used by connecting to a computer or a similar device.

On the other hand, it is used to indicate a specific part of the screen when giving a presentation. In the past, an indicator rod or the like was used, but recently, a laser pointer is generally used. Laser pointers are being used a lot because they are easy to carry and can be used even when the presenter is spaced far from the screen.

Conventionally, a portable computer is mainly used by connecting to an external display device such as a projector. However, in the case of using a portable computer, there is a disadvantage in that it is portable, but it is inconvenient to carry because of its bulky and heavy weight, and it is inconvenient to carry the portable computer itself in order to output a small amount of screen data.

In addition, since the operation of the portable computer is not simple, those who are not familiar with the operation of the computer have been inconvenient to use, and in order to prepare for the misoperation of the computer that may occur during the presentation, the presenter is required to learn the operation of the computer. There was an inconvenience of having to spend time.

In addition, if space is limited, for example, when the projector is far away, the presenter cannot directly operate the portable computer. Therefore, a separate person other than the presenter may be required because a person who needs to operate the portable computer will be required as the presentation proceeds. There was a necessary problem.

In addition, the screen data of the portable computer should be changed as the presenter progresses. As the two people progress, the presenter and the computer operator have an inconvenience in needing an effort to match such a motive with a glance or a hand signal.

Conventionally, in storing the data after the presentation, it may be stored in a computer or stored in a separate auxiliary memory device, or may be stored by printing one by one. However, storing them on a computer could cause data corruption while using the computer. Storing in auxiliary memory also had the inconvenience of using a computer again to see the data again. In the case of printing and storing the document, the amount is huge and bulky, which makes it difficult to store the data, and it is also inconvenient to find the data.

In the case of using a conventional computer connected to a projector, the screen required for the presentation was created with a computer using Microsoft Corporation's PowerPoint or similar screen creation program, and the screen was output to the projector. Therefore, when there are unnecessary screens among the created screens or when a screen to be added is needed, it is inconvenient to edit the screen again.

On the other hand, most of the presentation to convey their opinions and the like to a large number of people in a predetermined time. Therefore, the presenter should make a presentation in consideration of the time and contents. However, in the related art, there is a problem that it is difficult for the presenter to grasp how much contents remain, how much time has elapsed, and which side is currently in progress on the screen.

Laser pointers used in presentations are commonly used in recent years due to many advantages, such as being portable and not limited by space. However, the presenter was inconvenient to prepare such a pointer separately in the process of preparing the presentation, the laser pointer is inconveniently lost because of its small size.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and is an object of the present invention is to provide a presentation device that is easy to carry and use, can conveniently manage presentation materials, and can easily select screen data required for presentation. .

In addition, an object of the present invention is to provide a presentation device that the presenter can directly control the output of the screen according to the progress of the presenter, and can easily grasp the information and the running time of the currently output screen.
