Description

Performance Hall Lecture Data Linkage System}

The present invention relates to a system for linking lecture data at a performance hall, which facilitates sharing of presentation data to audience members.

Due to the rapid development of science and technology, various detailed technologies belonging to one industrial field are being developed by leading companies, research groups affiliated with hospitals, and research groups affiliated with universities around the world.

Accordingly, various international academic conferences are being held to prevent overlapping investment in technology development and accelerate the development of the relevant technology field by sharing development technologies among companies, hospital-affiliated research groups, and university-affiliated research groups. Participating researchers or experts usually range from hundreds to thousands of people.

For this reason, not only does the presentation period take several days, but also the presentation venue is tightly operated by setting the presentation time from at least five or six to as many as dozens of simultaneous dozens of people in minutes.

On the other hand, a QR code is a matrix-type two-dimensional barcode representing information in a black and white plaid pattern. QR codes are mainly used in Japan, Korea, and the United States, and the name is derived from the registered trademark "Quick Response" of a company called Denso Wave in Japan. It is a two-dimensional barcode that overcomes the capacity limitation of barcodes that have been widely used in the past and expands its form and content. It has vertical and horizontal information and can store character data in addition to numbers. Usually, it is read and used with a digital camera or dedicated scanner, but recently, as the use of smart phones with cameras is spreading, various commercial services are being used.

When a QR code is recognized with an Internet-connected smartphone, etc., immediately separate website information, text message, image, SMS (Short Message Service) message, e-mail information, WIFI Internet access information, major notification information, geolocation information, It is possible to acquire personal information, etc., and related services are currently being used in various industrial settings.

On the other hand, a beacon is a wireless communication device that transmits a signal to nearby devices using a Bluetooth low energy protocol to transmit location information.

In addition, in the case of large-scale academic conferences, presentations are made at a presentation place prepared by dividing a large performance hall into a plurality of sections. There is a problem that not only interferes with smooth progress in the process, but also takes a lot of time.

In order to solve these problems, the need for a concert hall lecture data linkage system that can share presentation materials with the audience using QR codes or beacons is emerging.

In addition, Equation 4 includes characters, images, figures, and media files in any one page of the presentation material, and reflects the complexity of the images and figures included in the page by the complexity extractor 1286. It is used when calculating the expected presentation time for one page, and Equation 4 is as follows.

It means the complexity of images and figures for .

The complexity extracted by the complexity extractor 1286 may have any one value between 0 and 5. That is, the simpler the image or figure, the closer the complexity is to 0, and the more complex the image or figure, the closer to 5 the complexity.

The complexity may be adjusted to have a value different from that of one embodiment of the present invention depending on the presentation environment, but it is preferable to set the complexity to have a higher value as images and figures included in a specific page of the presentation material become more complex.

)은 180초가 된다.For example, in the example used to explain Equation 1, if the complexity of the images and figures included in page 3 determined by the complexity extractor 1286 is 2, the presentation data calculated by Equation 4 Estimated presentation time for page 3 (

) becomes 180 seconds.

That is, as the complexity of images and figures included in any one page of the presenter table increases, the estimated required presentation time for each page derived from the page presentation time calculation unit 1287 increases.

This is to reflect the fact that the more complicated the images and figures included in the presentation materials, the longer it takes to explain the images and figures.

On the other hand, when the presentation material includes all text, images and figures, and media files, the complexity of the images and figures included in each page of the presentation material is extracted by the complexity extraction unit 1286, and the media extraction unit ( After extracting the playback lengths of video and audio files included in each page of the presentation material in 1285), the page presentation time calculation unit 1287 may calculate the expected presentation time for each page based on Equation 5 below.

) is 210 seconds.

The total presentation time calculator 1288 uses the expected presentation time for each page calculated by the page presentation time calculator 1287 based on Equation 2 below, Calculate the expected presentation time for one presentation material.

For example, if the presentation material consists of a total of 10 pages, and the expected presentation time calculated for each page calculated by the page presentation time calculator 1287 is 200 seconds, the total presentation time calculator ( 1288) can calculate the time required to present the presentation material as 2000 seconds.

The presentation time calculation unit 1289 per letter calculates the time required for a presenter to speak per letter by Equation 6 below based on the past presentation time of the presenter.

The time required for one presenter to announce per letter calculated by Equation 6 is calculated by Equation 1, Equation 3, and Equation 3 in the page presentation time calculation unit 1287 that calculates the estimated required presentation time for each page again. 4, can be used in Equation 5.
