Computers have been used in meetings for some time. Computers have been used to take minutes in real time. It is almost common practice now to use a computer and an attached projector when presenting information to a group at a meeting. Several attempts have been made, with varying success, to address meetings with remote participants. Initially, meeting participants would e-mail documents to all expected attendees for presentation during the meeting. Presentations were synchronized by the leader's instructions during a teleconference. Later, products such as Microsoft NetMeeting allowed the use of file distribution during the meeting and interactive tools such as a white board would allow real-time interaction between users. NetMeeting allowed screen sharing of presentation data but required that the file be opened manually outside NetMeeting and then manual identification of the process from within NetMeeting. When multiple files were open in one application, there was room for error in which file was shared. Web-based services, such as LiveMeeting require manual upload of a file to a server before sharing can take place. Often, everyone in attendance at an electronic meeting would receive copies during the meeting. Multiple copies of data were routinely left as artifacts of the meeting and contributed to confusion over versioning. Additionally, the user interface for file sharing was manual and menu-driven.
Drag-and-drop user interaction has been used as a shortcut for certain menu picks, such as, copy, move, and print. However, a drag-and-drop interface has been limited to such file-oriented operations.
A user interface for starting presentations in a meeting advantageously combines the familiar drag-and-drop interface with the automatic identification of application programs associated with data files for presentation and peer-to-peer network connectivity techniques. This combination provides a simple and intuitive user interface for starting shared presentations during an on-line meeting. Peer-to-peer networking infrastructure develops and manages the sharing and connectivity required to set up the links with meeting attendees and delivers the appropriate data streams to network resources associated with the attendees.
First icons representing data may be selected and moved onto second icons representing meeting participants or other network resources, such as participant's computers or projectors.
Although the following text sets forth a detailed description of numerous different embodiments, it should be understood that the legal scope of the description is defined by the words of the claims set forth at the end of this disclosure. The detailed description is to be construed as exemplary only and does not describe every possible embodiment since describing every possible embodiment would be impractical, if not impossible. Numerous alternative embodiments could be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims.
It should also be understood that, unless a term is expressly defined in this patent using the sentence “As used herein, the term ‘______ ’ is hereby defined to mean . . . ” or a similar sentence, there is no intent to limit the meaning of that term, either expressly or by implication, beyond its plain or ordinary meaning, and such term should not be interpreted to be limited in scope based on any statement made in any section of this patent (other than the language of the claims). To the extent that any term recited in the claims at the end of this patent is referred to in this patent in a manner consistent with a single meaning, that is done for sake of clarity only so as to not confuse the reader, and it is not intended that such claim term by limited, by implication or otherwise, to that single meaning. Finally, unless a claim element is defined by reciting the word “means” and a function without the recital of any structure, it is not intended that the scope of any claim element be interpreted based on the application of 35 U.S.C. § 112, sixth paragraph.
Much of the inventive functionality and many of the inventive principles are best implemented with or in software programs or instructions and integrated circuits (ICs) such as application specific ICs. It is expected that one of ordinary skill, notwithstanding possibly significant effort and many design choices motivated by, for example, available time, current technology, and economic considerations, when guided by the concepts and principles disclosed herein will be readily capable of generating such software instructions and programs and ICs with minimal experimentation. Therefore, in the interest of brevity and minimization of any risk of obscuring the principles and concepts in accordance to the present invention, further discussion of such software and ICs, if any, will be limited to the essentials with respect to the principles and concepts of the preferred embodiments.
The computer 110 may also include a cryptographic unit 125. Briefly, the cryptographic unit 125 has a calculation function that may be used to verify digital signatures, calculate hashes, digitally sign hash values, and encrypt or decrypt data. The cryptographic unit 125 may also have a protected memory for storing keys and other secret data. In addition, the cryptographic unit 125 may include an RNG (random number generator) which is used to provide random numbers. In other embodiments, the functions of the cryptographic unit may be instantiated in software or firmware and may run via the operating system or on a device.
Computer 110 typically includes a variety of computer readable media. Computer readable media can be any available media that can be accessed by computer 110 and includes both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer readable media may comprise computer storage media and communication media. Computer storage media includes volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Computer storage media includes, but is not limited to, RAM, ROM, EEPROM, FLASH memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and which can accessed by computer 110. Communication media typically embodies computer readable instructions, data structures, program modules or other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media includes wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, radio frequency, infrared and other wireless media. Combinations of any of the above should also be included within the scope of computer readable media.
The system memory 130 includes computer storage media in the form of volatile and/or nonvolatile memory such as read only memory (ROM) 131 and random access memory (RAM) 132. A basic input/output system 133 (BIOS), containing the basic routines that help to transfer information between elements within computer 110, such as during start-up, is typically stored in ROM 131. RAM 132 typically contains data and/or program modules that are immediately accessible to and/or presently being operated on by processing unit 120. By way of example, and not limitation,
The computer 10 may also include other removable/non-removable, volatile/nonvolatile computer storage media. By way of example only,
The drives and their associated computer storage media discussed above and illustrated in
The computer 110 may operate in a networked environment using logical connections to one or more remote computers, such as a remote computer 180. The remote computer 180 may be a personal computer, a server, a router, a network PC, a peer device or other common network node, and typically includes many or all of the elements described above relative to the computer 110, although only a memory storage device 181 has been illustrated in
When used in a LAN networking environment, the computer 110 is connected to the LAN 171 through a network interface or adapter 170. When used in a WAN networking environment, the computer 110 typically includes a modem 172 or other means for establishing communications over the WAN 173, such as the Internet. The modem 172, which may be internal or external, may be connected to the system bus 121 via the input interface 160, or other appropriate mechanism.

The communication media typically embodies computer readable instructions, data structures, program modules or other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any information delivery media. A “modulated data signal” may be a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media includes wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media. Computer readable media may include both storage media and communication media.
After a peer-to-peer network meeting has been established, a presenter may wish to show materials to the meeting attendees. The presenter may select one of the first icons. The operating system 134 or a process associated with a meeting window 206 may monitor 406 the selection of the first icon 202204. The presenter may then move the first icon 202204 to an appropriate second icon 208210 and release the first icon 202204 over the second icon 208210. This so-called drag-and-drop 408 motion initiates activities associated with presenting the data to the meeting participants, via the network resources (computers 1222, projector 13, etc.) associated with the second icon.
In a fashion similar to opening a file for local viewing, the drag-and-drop motion may require the application program associated with the first icon to be started 410. If the application is already running, the program may not need to be started. In either case, when the application program is running, the process associated with the application may be identified 412. Data output from the identified process may be monitored and used to create 414 a data stream. Using standard peer-to-peer networking techniques, for example, a terminal services session, the data stream may be transmitted 416 to the various network resources previously identified. A meeting window, similar to or the same as window 206 on the networked resource 210 may be used to render or otherwise output 418 the data stream. In one embodiment, the data stream includes graphical data interface (GDI) information.
