Description
    BACKGROUND OF THE INVENTION
  • [0001]
    Audio and video conferencing provides a significant resource to those who reside in distant locations. Critical information may be exchanged in an effective manner without the inconvenience of traveling to meet with other parties. Although it has become a significant tool, audio and video conferencing has a number of limitations related to its use.
  • [0002]
    One disadvantage related to audio/video conferencing relates to effectively utilizing a vast number of different features available to configure a conference call. Typical features provided by conferencing systems include the ability to create side conferences, conduct roll calls, mute one or more participating members, and provide pre-recorded broadcast messages to one or more participants. Often, remembering the vast number of different features poses a problem for many users. Because of the number of features, a reference card is provided to a user for use during a conference call. These cards, however, are often printed in small type and are very difficult to interpret and use.
  • [0003]
    Another issue in configuring one or more features of conference calls relates to implementation. Often, implementing a particular feature requires keying in a string or a sequence of DTMF (dual tone multi-frequency) tones. The sequences may be long and remembering a sequence may be a very difficult process. Further, remembering more than a few of these sequences may be a very arduous task.
  • [0004]
    A significant disadvantage to current conferencing systems involves the difficulty and complexity of invoking various feature sets while participating in a conference call. A participant may have to enter one or more states or modes in his conferencing device prior to entering the appropriate DTMF sequence that allows him to configure his conferencing device with the desired feature. The process is not intuitive and a participant may run into significant problems during a conference call. Often times, a call may be dropped or a conference call may be terminated if the wrong DTMF sequence is input. This often causes unwanted frustration to users who become more hesitant to use such features in the future.
  • [0005]
    Finally, DTMF tones often result in irritating audible distractions during a conference call. This often occurs when a participant enters or exits a conference call while a conversation is occurring during the conference call or when a user wishes to invoke a particular feature. In addition to annoying a participant, the wrong sequence of DTMF tones may terminate a conference call.
  • [0006]
    Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with some aspects of the present invention as set forth in the remainder of the present application with reference to the drawings.

  • [0019]
    The audio/video conferencing call system 100 may be capable of providing a number of features that are facilitated by the server 124. The server 124 may facilitate a request by a participant to arrange a private side conference for two or more participants. In response, the server 124 may securely acknowledge such a side conference request by way of an encrypted message using one or more secure encryption algorithms. A side conference may be securely transmitted to those participants who have been authorized to view the side conference. It is contemplated that the participant may be authenticated by way of one or more user name and passwords prior to being accepted into a conference call. In one embodiment, fingerprints or facial profiling may be used to identify a participant. It is contemplated that one or more suitable computer input devices are used to facilitate a fingerprint or facial profiling recognition system. In addition, the server 124 may facilitate a request by a participant to mute himself while a conference call is underway, to lock or bar other parties from attending a conference that has begun, to mute all participants during a pre-recorded broadcast of a conference call, and to mute or reduce the volume of another party during a conference call. It should be noted that these are a few example embodiments of requests made by a participant causing a configuration change in the conference call setup environment. It is contemplated that a graphical user interface may be additionally enabled for a host's or administrator's use. By logging in as a host or administrator, by way of an authorized user name and password, it is contemplated that the graphical user interface (GUI) may be enabled to allow administrative control of the exemplary requests previously mentioned. It is contemplated that a user may log in as a host or administrator using the server 124 or any one of the other computing devices 104, 108, 112, 116 illustrated in FIG. 1.

  • [0029]
    Referring to FIG. 4, it is contemplated that a side conference call may be configured by an authorized user, such as an administrator or host, by pointing, clicking, and dragging (using an exemplary mouse) a particular participant identifier over to a new conference call identifier, thereby creating a new conference call. For example, an administrator may point, click, and drag participants identifiers #3 and #5 of conference call #1 into the conference call #3 identifier. By doing so, participants #3 and #5 become participants of conference call #3. It is contemplated that the device that performs the pointing, clicking, and dragging of one or more objects within a graphical user interface comprises a mouse or like device. It is contemplated that, in one embodiment, requests made by prospective participants to generate a side conference call is agreed upon by the participants involved. It is contemplated that the server automatically generates a new conference call when all conditions are met for staging a new conference call. The conditions may comprise that a conference call be restricted certain participants or a number of participants. For example, the side conference may comprise members of a company or organization.
  • [0030]
    When there is more than one conference call available, the audio/video conferencing system may allow a participant to choose which conference call in which he would like to participate. Each conference call may be identified by way of a conference identifier. The conference identifier may comprise a software object that incorporates a conference call name. The conference identifier may comprise a software object that may incorporate a unique icon, logo, or other unique insignia. The graphical user interface may provide a default mode in which the first conference call identified by conference identifier #1 is provided as the audio and/or video feed. When the first conference call's audio feed is provided to the participant, the graphical user interface may highlight or color the conference identifier #1. In this fashion, the participant is visually notified as to the conference call in which he is listening and participating. It is contemplated that a user may select another conference call by way of using his exemplary mouse. For example, the appropriate conference call identifier may be selected by right clicking on the mouse to display one or more selection choices. An exemplary selection choice may be “select audio feed”, which may be selected by left clicking on the mouse. If another conference call is selected, the associated conference identifier may be colored or highlighted appropriately.
  • [0031]
    It is further contemplated that security of a conference call may be adjusted by way of the graphical user interface. For example, a particular conference call identifier may have a number of selections regarding the security used when a participant participates in a particular conference call's transmission. It is contemplated that the level of security or security standard used may be determined by right clicking on the mouse and selecting an appropriate security level for the conference call selected.
  • [0032]
    As illustrated in the embodiment shown in FIG. 4, a conference call may be locked to prevent others from participating in the conference call. This may occur when a particular time has elapsed after the conference call has started. In other instances, the conference call may be locked when a certain number of participants have been reached. The criteria for locking the conference call may be determined by an administrator prior to scheduling an audio/video conference.
  • [0033]
    While the invention has been described with reference to certain embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the scope of the invention.
