Definitions

• the present invention relates to techniques for integrating, in audio-visual presentations, means for accessing sources of information, and more particularly to a system and a method for enabling an auditor, during the course of a presentation, to select one or several topics drawing his attention or interest, and, immediately after said presentation or at a later time, to easily access information related to the topics previously selected.
• Presentation systems allow to create electronic foils, slides or pages and to assemble them to form a presentation that can be displayed. Presentation systems are used, during the course of a presentation, to select and display electronic foils to an audience, for illustrating and completing the speaker's explanations. In particular, presentation systems allow to advance to the next foil, to return to the previous foil or to go to any other foil within the presentation using a graphical user interface or a keyboard. The speaker also has the possibility to navigate from one foil to another, for instance to skip some foils, to present the more relevant foils of the presentation, or to present foils requested by some auditors.
• a presentation system can generate or reference a sequence of HTML files stored on one or a plurality of Web servers, each HTML file being accessible by activating an hyperlink from the presentation system, said hyperlink comprising an address for locating the HTML file in the network (for instance an Uniform Resource Locator (URL) in the internet network).
• URL Uniform Resource Locator
• the speaker can present all or a subset of the HTML foils depending on the timing of the presentation, the interest shown by the auditors, or any other factor. Therefore, the presentation of foils and related topics can flow sequentially or in any other convenient order, depending on the course that the presentation takes and the amount of time spent for each topic (i.e., to each chart or slide of the presentation).
• the auditor of a presentation is interested in some particular topics, and not particularly interested in topics considered as being irrelevant or already known to him.
• the auditor wants to select, during the course of the presentation, not all the foils that are presented by the speaker, but merely a few foils, related to the topics that have drawn his interest or attention, so that he can directly and immediately access and review, once the presentation is over, the selected foils.
• a system and method is needed for recording information in a transparent way for the speaker while keeping the audience's attention on particular topics without needing to take notes.
• the selection of foils by the audience for a subsequent display should be as simple as pressing a button, and sufficiently flexible to deal with the dynamic content provided by presentation systems.
• the present invention is directed to a system, method and computer program, as defined in independent claims, for enabling an auditor in the course of a presentation, to select one or several topics drawing his attention or interest, and, immediately after said presentation or at a later time, to easily access information related to the selected topics.

• Figure 16 shows the steps of the method for accessing information related to topics that have been selected during a presentation, according to the present invention.
• each auditor (100) attending a presentation has one or several particular topics of interest. At some moments, this auditor is particularly interested from what the speaker (102) is saying (103) or from what is being shown on the presentation screen (104), and while at other moments, this auditor may consider that the presented topics are already known, lack of interest or are irrelevant.
• the principle of the invention as illustrated by Figure 2 is based on the synchronization of the speaker workstation (202) (i.e., the computing system under the control of the speaker (201) which is connected to the presentation screen (203)) with the auditor devices (204) (e.g., a PDA, a hand-held computer, a wearable computer, a smart phone) to the same universal time.
• speaker workstation (202) and auditor's devices (204) are synchronized according to an universal time system (205), such as the Global Positioning System Time (GPS-time), the Global Orbiting Navigational Satellite System (GLONASS) time or another suitable universal time based on a satellite system.
• GPS or GLONASS receiver (207) is integrated or connected to the speaker workstation (202).
• GPS or GLONASS receivers (208) can be integrated or connected to the auditor (200) devices (204), (e.g., wearable computers, Personal Digital Assistants (PDAs), smart phones or any other hand-held computing device).
• the auditor devices (204) are independent and are not connected nor in communication with the speaker workstation (202).
• Figure 12 also shows how events (1202) generated by an auditor (600) (such as the universal times Ta, Tb corresponding to the selection by the auditor of a first and a second topic), can be correlated with events (1201) generated by the speaker (602) (such as the universal time intervals (T1.T2), (T3, T4) corresponding to the oresentation by the speaker of Foil 1 and Foil 3).
• This correlation of independent ..vents is based on the synchronization of the speaker workstation (202) with the auditors devices (204) according to an universal time (205). This correlation allows t he identification of the foils that have been selected by the auditor during the course of the presentation.
• Universal Timing Systems such as the universal times Ta, Tb corresponding to the selection by the auditor of a first and a second topic
• Timing sequences independent of locations of transmitters and receivers, can be derived from an absolute timing reference such as, for example, the Global Positioning System (GPS) time or the Universal Time Co-ordinated (UTC) time (also known today as GMT and ZULU time).
• GPS Global Positioning System
• UTC Universal Time Co-ordinated
• the GPS uses 24 satellites in 55° inclined orbits 10,000 miles above the earth. These timing signals are used by any GPS receiver anywhere on the earth to determine its position.
• a 1575 MHz transmission carries a 1-MHz bandwidth phase-modulated signal named the clear acquisition (C/A) code.
• C/A clear acquisition
• a GPS receiver receives this signal from at least three GPS satellites, it can determine its own latitude and longitude with an accuracy of about 30 meters.
• the GPS is today widely used for distributing Precise Time and Time Interval (PTTI).
• PTTI Precise Time and Time Interval
• the system uses time of arrival (TOA) measurements for determining a position.
• a precisely timed clock is not essential for the user because time is obtained in addition to position by the measurement of the TOA of four satellites simultaneously in view.
• GPS is today the world's principal supplier of accurate time. It is used extensively both as a source of time and as a means of transferring time from one location to another. Three kinds of time are available from GPS: GPS time, UTC as estimated and produced by the United States Naval Observatory, and the times from each free-running GPS satellite's atomic clock.
• MCS Master Control Station
• a Kalman filter software program estimates the time error, frequency error, frequency drift and Keplerian orbit parameters for each of the satellites and its operating clock. This information is uploaded to each satellite so that it can be broadcasted in real time. This process provides GPS time consistency across the constellation to within a small number of nanoseconds and accurate position determination of the satellites to within a few meters.
• the second universal time standard, Universal Time Co-ordinated (UTC) introduces leap seconds to remain synchronized with the rotation of the earth.
• UTC Universal Time Co-ordinated
• a set of UTC corrections is also provided as part of the GPS broadcast signal.
• This broadcast message includes the time difference in whole seconds between GPS time and UTC. This complicates software that deals with the smooth flow of data streams or calculates the times between data samples.
• GPS Time is preferred in this invention as this system avoids the introduction of leap seconds and is easily related to UTC.
• Information about UTC (GMT) time service can be found on: http://time.greenwich2000.com/
• a Direct-to-Digital GPS Receiver is described in the following Web site : http://w3.research.ibm.com/present/gto200038.htm
• This receiver has been jointly developed between IBM and Leica.
• GPS derived position information is finding a multitude of diverse applications: from mapping and surveying to vehicle tracking to 911 cell phone caller location to automated farm equipment to even robotics golf carts...
• This receiver chip reduces the radio dimensions and complexity.
• the incoming GPS signal is literally digitized right at the antenna, then filtered digitally in a CMOS based chip.
• This direct digitization is made possible by the ability of SiGe technology to run at high speed on very little power, and the core of this technology is a SiGe based Analog to Digital Data Converter.
• GPS or GLONASS receivers must be integrated or connected to the speaker workstation (202) (e.g., a Personal Computer), and to auditor devices (204) (e.g., wearable computers, Personal Digital Assistants (PDAs), smart phones, WAP enabled phones, games consoles).
• the universal timing signals that are received from GPS or GLONASS satellites are used to initialize and synchronize the internal electronic clocking systems according to the same universal time.
• timing information must be continuously derived from the autonomous electronic clocking systems of those devices.
• a more or less frequent periodic reception of satellite signals must be performed.
• the user device If the user device is fixed or installed in a house or building during long periods, the user device must be connected to an outdoors installed GPS or GLONASS antenna, (e.g., antenna installed on the roof of the building).
• GPS or GLONASS antenna e.g., antenna installed on the roof of the building.
• a presentation is structured as a set of HTML foils stored on one or a plurality Web servers.
