A system and method for making information accessible. The present invention requires the audience to do this with the least amount of effort and intervention possible (simply by pressing a select button on the audience's device). When the presentation is over, the audience can find information directly related to the selected topic. The system claimed in the present invention synchronizes the local time of the speaker workstation and the local time of the audience device according to the same universal-time, so that the presenter selects the subject of interest to the audience and the time selected by the presenter. It is based on being able to correlate the time intervals at which presentation foils are presented. In a particular embodiment, the synchronization between the presenter workstation and the audience device is made with reference to a world standard time based on, for example, a satellite system.

Description

How to create a presentation timetable, how to select and access foils, presenter devices, audience devices, and computer programs {SYSTEM AND METHOD FOR SELECTING AND RETRIEVING INFORMATION FROM AN AUDIO-VISUAL PRESENTATION}

The presentation system can generate electronic foils, slides or pages, and assemble them to form a presentation that can be displayed. The presentation system is used to allow the description and completion of the speaker's description by selecting and displaying the electronic foil to the audience during the presentation. In particular, the presentation system may use a graphical user interface or keyboard to advance to the next foil, to return to the previous foil, or to any other foil in the presentation. In addition, the presenter can move between one foil and another, for example, skipping some foils, presenting a foil more relevant to the presentation, or presenting a foil requested by some audiences. can do.

The presentation system can create or reference a sequence of HTML files stored on one or more web servers, each of which can be accessed by activating hyperlinks in the presentation system. The hyperlink includes an address (e.g., a Uniform Resource Locator (URL), etc. in the Internet network) for determining the location of the HTML file within the network. During the presentation, the presenter can provide all or a subset of the HTML foil depending on the timing of the presentation, the degree of interest represented by the audience, or other factors. Therefore, the presentation of the foil and related topics is sequentially determined according to the progress that the presentation takes and the amount of time spent on each topic (ie, on each chart or slide in the presentation). Or in any other convenient order.

In general, the audience of a presentation is interested in some particular subject and does not have particular interest in regard to some subjects as unrelated to or already known to him. Thus, because the audience often wants to select only a few foils related to his or her interest or attention, rather than all the foils presented by the presenter during the presentation process, the audience is selected at the end of the presentation. The foil must be accessible directly and immediately.

Accordingly, there is a need for a system and method that allows the presenter to record information in a manner that is not recognized by the presenter without taking notes while the audience is interested in a particular subject. Selecting the foil to be displayed later by the audience should be as simple as pressing a button and should be flexible enough to handle the dynamic content provided by the presentation system.

The present invention relates to a technique for incorporating means of accessing a source of information into audio-visual presentations, more specifically during the presentation of an audience's attention or interest. A system and method are provided that enable selection of one or more topics that turn off and facilitates access to information related to a previously selected topic immediately after the presentation or after a period of time.

As shown in FIG. 1, each audience 100 attending a presentation has one or more specific topics of interest. At some moment, the audience may be of particular interest from the presentation 103 of the presenter 102 or the presentation on the presentation screen 104, and at another moment, the audience already knows the subject being presented or It may be regarded as uninteresting or unrelated to oneself. Under these circumstances, during the presentation, the audience 100 only selects topics of his own interest (eg, "Pomerol", "Medoc" during long presentations on "French red wine"). ) "And" Bourgogne "wine only information, etc.) and, over time, information related to the selected topic (especially presented by the presenter, within the foil dealing with the selected topic). It is necessary to provide a simple mechanism to make the information (included) accessible.

As shown in FIG. 2, the principles of the present invention include a presenter workstation 202 (ie, a computer system connected to the presentation screen 203 and under the control of the presenter 201) and the audience device 204 ( For example, PDAs, portable computers, wearable computers, smart phones, etc.) are based on synchronizing the same world standard time of day. In a preferred embodiment of the present invention, the presenter workstation 202 and the audience device 204 are based on a Global Positioning System Time (GPS), Global Orbiting Navigational Satellite System (GLONASS) time or other satellite system. Synchronized according to a world standard time timing system 205, such as an appropriate world standard time.

This correlation for irrelevant events is based on synchronizing the presenter workstation 202 with the audience device 204 in accordance with the world standard time 205. This correlation enables the identification of the foil selected by the audience during the course of the presentation.

Universal Standard Timing Systems

Timing sequences independent of the position of the transmitter and receiver are, for example, Global Positioning System (GPS) time or Universal Time Co-ordinated (UTC) time (also known as GMT and ZULU time today). Can be derived from the same absolute time reference.

To transmit accurate timing signals, GPS uses 24 satellites that orbit along an orbit with a tilt of 55 ° away from the Earth. Anywhere on earth, with a given GPS receiver, these timing signals can be used to determine their location. In 1575 MHz transmission, a 1-MHz bandwidth phase-modulated signal called a clear acquisition (C / A) code is carried. When the GPS receiver receives this signal from at least three GPS satellites, the GPS receiver can determine its latitude and longitude with an accuracy of approximately 30 meters. Apart from determining geographic location, GPS is now widely used for the distribution of Precise Time and Time Intervals (PTTIs). The system uses time of arrival (TOA) measurements to determine the location. Since the time can be obtained in addition to the location by measuring the TOA of the four satellites entering the field of view at the same time, the user does not necessarily have to have a precisely timed clock. If altitude is known, three satellites are sufficient. If the user is stationary at a known location, in principle, time can be obtained by observing one satellite. Information about GPS visual services is available at http://tycho.usno.navy.mil/, operated by the "Time Service Department" at the US Naval Observatory in Washington, DC.

Today, GPS is a major source of accurate time around the world. GPS is widely used as a source of vision and as a means of transmitting time from one location to another. There are three types of time available from GPS: GPS time, UTC estimated and generated by the US Naval Observatory, and time available from the atomic clock of each free-navigating GPS satellite. Master Control Station (MCS) at the Falcon Air Base near Colorado Springs, Colorado, USA, collects GPS satellite data from five monitor stations around the world. The Kalman filter software program estimates the time error, frequency error, frequency drift and Keplerian orbit parameters for each satellite and its operating clock. This information can be uploaded to each satellite and broadcast in real time. This process provides GPS time consistency in a few nanoseconds across the constellation and provides accurate positioning within a few meters by satellite.

Universal Time Co-ordinated (UTC), the second world standard time standard, introduces leaf seconds to keep the earth rotating and synchronized. In order to provide an estimate of UTC time derivable from the GPS signal, a set of UTC corrections is also provided as part of the GPS broadcast signal. This broadcast message includes the time difference between the total seconds of GPS time and the total seconds of UTC. This complicates the software to handle the gentle flow of the data stream or to calculate the time between data samples. GPS time is preferred in the present invention because the system can be easily associated with UTC by avoiding the introduction of leaf seconds. Information about UTC (GMT) time services can be found at http://time.greenwich2000.com/.

GPS receiver

Direct-to-Digital GPS receivers are described at the following website:

http://w3.research.ibm.com/present/gto200038.htm

This is an example of an inexpensive, compact chip that can integrate GPS into any device (eg, PDAs, mobile phones, wearable computers, video cameras, etc.). The receiver was jointly developed by IBM and Leica. When integrated with the CMOS technique, the high-speed analog performance of the SiGe technique allows the integration of this single chip directly into a digital Global Positioning System (GPS) receiver. Location information derived from GPS has been identified for a variety of uses, from cartography and surveying to vehicle tracking of 911 telephone call callers, automated agricultural vehicles and robotic golf carts. This receiver chip reduces radio range and complexity. Not only are there no analog mixer stages, but expensive discrete components that require conventional two stage analog down conversion (such as high quality filters). does not exist. Instead, the input GPS signal is fully digitized directly at the antenna and then digitally filtered within the CMOS based chip. This direct digitization is made possible by the ability of SiGe technology to run at high speed with very little power, the core of which is an analog-to-digital data converter based on SiGe.

In accordance with the present invention, a GPS or GLONASS receiver may include a presenter workstation 202 (e.g., a personal computer) and an audience device 204 (e.g., a wearable computer, personal digital assistants (PDAs), smart phones, WAPs). Enabled telephones, games consoles, etc.). Using a world standard time timing signal received from a GPS or GLONASS satellite, the internal electronic clocking systems are initialized and synchronized according to the same world standard time. During periods when the GPS or GLONASS satellites are outside the field of view (for example, the user's device is in a building or not connected to an external antenna, etc.), and therefore no timing signal is received from such satellites, the timing information is sent to these devices. Should be derived continuously from the automatic electronic clocking system. Depending on the drift of the clocking system installed within the device, and also to maintain sufficient timing accuracy, and to ensure that the audience device and the presenter workstation are synchronized to the same world standard time, periodic recognition of the satellite signal must be performed somewhat often. do. Practically,

If the user device is portable, a satellite signal will be received when the user is outdoors or traveling.

If the user device is fixed or fixed for a long period of time in a home or building, the user device must be connected to the outdoors with a GPS or GLONASS antenna (eg an antenna installed on the building roof).

Presentation Hyperlink Table

As shown in Figure 3, a presentation according to a preferred embodiment of the present invention is configured as a set of HTML foils stored on one or more web servers. This web server is preferably referenced to the presentation hyperlink table 300 stored at the presenter workstation 202. For each presentation foil, the presentation hyperlink table is

Inputting a selection command 605 to his workstation 601 to select 1505 a foil corresponding to the subject of interest;

Determine (1506) the world standard time 606 at the time using a world standard time device (e.g., a GPS receiver, etc.) integrated or connected to his workstation;

The world standard time at that time is recorded (1507) in the selection time table.

The following table, also shown in FIG. 7, is an example of a selection time table created on the audience workstation 601 during a presentation (eg, a presentation about "French Red Wine", etc.). Each row of this table corresponds to the audience's choice of foils presented by the presenter at the world standard time recorded in the first column. In the header portion of this table, the audience copied the URL 701 of the presentation time table (eg, http://www.directbuyer.com/presentation-0173.htm/). This URL is provided to the audience by the presenter before the presentation.

How to access and display the selected foil

During a presentation (eg, a presentation entitled "French Red Wine", etc.), the audience 600 selects one or more topics 604 of interest and corresponds to these selected topics. When the world standard time 606 is stored and recorded in the selection time table 700 on the audience workstation 601, the audience or observer is selected foil within the presentation server 803 using the method shown in FIG. Retrieve the name and URL associated with. The retrieved name and URL are stored locally in the selection time table 700 on the audience workstation 601. From the updated selection time table, the audience can select, retrieve and display any of the foils. The method for enabling an audience of a presentation to access and display a selected foil from a workstation includes the following steps.

Accessing the presentation time table 802 on the presentation server 803 from the workstation 800 (1601).

Delivering 1602 the world standard time of selection recorded in the selection time table 700 located on the workstation 800 to the presentation server 803.

Querying 1602 the foil that is presented at this world standard time within the presentation time table.

Retrieving 1604 the presentation server 803 the identification means (name or description) 502 of the selected foil and the URL 503 associated therewith.

Storing the retrieved foil name and URL in the selection time table 902 (1605).

Selecting the foil 1001 from the selection time table 1002 (step 1606).

Activating a hyperlink 1003 at the workstation using a browser program (1607).

Accessing a foil on a server 1102 (preferably a web server) via a network 1103 (preferably an internet network) (1608).

Searching for foil 1104 in network 1103 and displaying foil 1104 on a workstation using browser program 1100 (1609).

8, 9, 10 and 11 illustrate several steps in accordance with the present invention. As shown in FIG. 8, when a presentation (eg, a presentation about "French Red Wine", etc.) ends, the audience may turn their workstation 800 into a communication network (eg, an Internet network ( 801, etc.). Using a software application running on the workstation of the audience, access the presentation time table 802 on the presentation server 803 to update the selection time table 804 stored locally on his workstation 800. do.

9 shows a process for updating the selection time table 900 on the audience workstation 800 using information stored in the presentation time table 901 located on the presentation server 803. Basically, for each world standard time recorded in the selection time table 900, the name and URL of the HTML foil presented by the presenter at that time is identified on the presentation time table 901, and the selection time table 902 is copied. The table below shows the selection time table updated by this process.

10 illustrates how an audience selects and accesses a previously selected HTML foil at their workstation 1000 during a presentation.

Basically, the audience specifies and selects HTML foil 1001 in the updated selection time table 1002. Using a software application located on the audience workstation 1000, the audience activates a hyperlink 1003 that points to the URL of the selected item. In the example shown in FIG. 10, the audience selects a subject of interest, “Medoc” 1001 (which is, in fact, the title of French red wine), and the URL, ie http: //www.french Enable hyperlink 1003 pointing to -wines.com/medoc.htm.

Finally, FIG. 11 shows an HTML foil 1101 (eg, medoc.htm) associated with the selected item 1001 (eg, “Medoc”) within the selection time table, via the network 1103. A method of receiving from a server 1002 (eg, www.french-wines.com) and finally displaying 1104 on an audience workstation 1100 is shown.

In the example described above, it has been described that after the presentation, the audience can access the preselected foil during the presentation process. In fact, during the presentation (for example, while the presenter is presenting a foil called “Bourgogne wines”), if the audience selects a topic of interest, the audience can be searched by the audience after the presentation is complete. Information related to the selected subject ("Burgundy wine") may be the following information.

HTML foil to be presented when a selection is made.

A long (HTML) document containing a description of La Bourgogne (geography, history, economy, agriculture) and a description of the wines produced in the region.

· A list of several web documents or references (hyperlinks) to "Les vins de la Bourgogne".
