Definitions

• the present invention relates to apparatuses and methods for presentation systems and more particularly to such systems for automatic adapting a presentation to an audience.
• presentation data is presented by a presenter (presentation operator) to a certain audience.
• the presentation may be, for example, a video presentation in which visual data, such as computer-generated graphics, are displayed on a monitor.
• the visual data may be a succession of still video frames or motion video pictures.
• audio data sound may also be played in speakers to accompany the video data being displayed.
• the presentations are often computer-generated, and may run under the control of the presentation operator.
• the presentation operator may, for example, advance the displayed still image to the next still image in the presentation at the appropriate time, or back up to a previously-displayed image in response to a question from an audience member.
• the presentation is typically designed with a given audience in mind.
• a presentation may include high-level mathematical equations.
• a presentation may be designed which omits equations.
• confidential data may be included in the presentation.
• Fig. 1 is a block diagram of a dynamic presentation system in accordance with an embodiment of the present invention.
• Fig.2 is a flow chart illustrating preferred method of operation of the system of Fig. 1 in accordance with the invention. Disclosure of the Invention
• a presentation is a display of at least visual content on a display device, with a presentation system, and/or audio played through a speaker.
• the presentation system may comprise a computer and a monitor, for example, and a database of presentation content and other presentation rules and data.
• System 100 comprises a computer such as PC 120, which has a processor 122 and memory 123. It is connected to wireless receiver means 121 , and to projector device 130 and speakers 132. Presentation content and data is stored in a database in memory 123, which may be RAM, CD-ROM, hard disk drive, or other types of storage or combinations of storage. Selected presentation content, in a particular format, is presented to the audience 110 via display means 131 and speakers 132.
• Each or a dependence of members 111 , 115, of the audience 110 includes, in an embodiment, a readable identification tag or device, e.g. a wireless identification means 112, 116, which can be read by receiver 122 to determine characteristics about the member.
• a readable identification tag or device e.g. a wireless identification means 112, 116
• the actual or prospective audience members may wear an RF tag or v-card, which stores information about the person, such as the person's name, position in the company, education, technical proficiency, and other status and characteristics of the person.
• RF tags sometimes referred to as RF transponder tags, RF-ID (identification) tags, RF-IDs, or electronic barcodes, can be an active or passive device.
• a passive RF tag typically has a capacitor which can be charged when the device passes through or is subjected to a sufficient RF field, to power the device.
• An external RF reader device can read information from the RF tag, for example by sending a wireless query to RF tag, which responds with information such as the identify of the item or person to which the tag is attached, a password, or status.
• RF tag systems are in use, for purposes such as production tracking, automatic toll collection, and anti-theft functions for consumer items.
• Many RF tags currently in use operate at relatively short distances, from a few inches to a few feet, while others operate from hundreds of feet to miles.
• Simple, inexpensive, passive RF tags used for anti- theft and product-identification purposes in stores, for example, are sometimes referred to as penny tags.
• content and rules for a dynamic presentation are stored in memory 123.
• the presentation is preferably an audio-visual, video, or audio presentation.
• PC 120 is able to present the data in different formats, and to select a format based on some characteristics or information about the audience, which is determined dynamically using receiver means 121.
• PC 120 determines characteristics of as many audience members as possible, and then characterizes the audience based on this information, in a way relevant to the presentation. This may be done by associating one or more "categories" with the audience.
• the categories depend on, and are normally defined for, the presentation itself. Typical categories for a given audience member may be based on age, job function, gender, income, security clearance.
• the audience may be characterized by assigning to it one or more categories, some of which are based on individual member categories. For example, the audience may be categorized by the total number of audience members, by the average age (based on the age categories or ages of individual members), and so on. Then, PC 120 changes the presentation format depending on the audience characteristics, e.g. depending on the categories that have been determined to be present.
• a presentation may be stored in memory 123 in both technical and non-technical formats.
• the audience 110 consists solely of engineers. Each engineer wears an RF tag containing this information, which is read by PC
• each engineer is categorized as "technical,” and the audience itself is characterized by the category “only engineers present”.
• Subsequent motion video or frames of the presentation displayed by projector 130 on display screen 131 thus include presentation content in the technical format, which is appropriate for an audience having only engineers.
• PC 120 selects the technical format based on the engineer-only characteristic of audience 110, equations, numbers, decimal points, and the like are presented to audience 131.
• the CEO of the company walks into the presentation room.
• wireless data is transmitted from the CEO's RF tag to receiver 121 , and PC 120 categorizes the audience 110 as now containing a CEO or nontechnical person. I.e., one audience category switches from “only engineers present” to "some non-engineers present”. Based on this change in audience characteristics, PC 120 changes to a non-technical or less technical format of the presentation.
• the presentation stops displaying equations and fractions and now displays information using pie charts, pretty colors, cartoon or stick figures, and the like. Concrete facts are replaced with buzzwords in vogue such as leverage, synergy, value-added, partner, challenge, innovative, empowerment, progressive and the like.
• intermediate content presentations may also be available and presented.
• the present invention is an adaptive presentation system that dynamically changes the presentation format based on audience characteristics, which are preferably determined by a wireless means.
• Fig. 2 there is shown a flow chart illustrating a method of operation 200 of dynamic presentation system 100.
• system 100 determines one or more audience characteristics (step 201).
• an initial presentation format is selected in accordance with this determination (step 202), and the presentation begins in this format (step 203). So long as there is no change in audience characteristics, the presentation continues in its current presentation format (steps 211 , 213).
• system 100 determines a changed audience characteristic
• the presentation format is adjusted accordingly (steps 211 , 212), and then the presentation continues from that point forward in the most recent presentation format, until the audience changes again.
• the presentation operator can overwrite the default behavior of the presentation system.
• alternative means may be employed by system 100 to discern audience information. For example, instead of using a wireless transmitter 112 on the audience member 111 and corresponding receiver 121 coupled to PC 120, a video camera and pattern recognition may be employed to recognize the person by facial features.
• system 100 detects the presence of audience members that do not carry a wireless transmitter, and uses this information to further tailor the mode or format of the presentation. For example, a video camera or turn-stile can detect the entry of a new audience member, even if the person does not have an RF tag.
• a dynamic presentation may be running which displays confidential information.
• Presentation system 100 detects the entrance of this person, but does not succeed in verifying that the person has the proper security presence (because they are not wearing an RF tag, for example). Thus, the presentation changes modes to an unsecure format in which confidential information is not displayed or otherwise presented.
• system 100 determines an audience characteristic (namely, that the audience contains an unverified person or person without an RF tag) and adjusts the presentation format accordingly.
• the presentation may be an advertisement, such as a video display on a sidewalk, under the control of PC 120.
• presentation system 100 contains some means for identifying some characteristics of the audience, i.e. the people walking by on the sidewalk, and changes the advertisement based on these characteristics.
• each customer may be provided with a special RF tag which may be customized to the person's characteristics.
• a video camera and pattern recognition techniques may be used to estimate characteristics of the passers-by (e.g., age, profession, gender, number of people, ethnic group, and the like), from which overall audience characteristics may be determined.
• the presentation system is a type of electronic "book” device, where, for example, the book content is displayed to the user on the book screen.
• the electronic book contains a means for characterizing the reader (audience) and changing the presentation format accordingly.
• system 100 has the further feature whereby audience members can interact wirelessly with the system 100 to change the presentation mode.
• audience members can interact wirelessly with the system 100 to change the presentation mode.
• the CEO can press a button on his transmitter indicating he is interested in seeing more detailed information, at which point the presentation displays more textual information and fewer graphics.
• the presentation format or mode may include who is in control of the presentation.
• a person in the audience may wish to temporarily control the presentation, i.e. to move a cursor on the screen 131 and double click an item for more detail.
• This person may have a wireless mouse device, which itself, or along with the person's RF tag, indicates to the system 100 that the person has authority to control the presentation in this manner.
