  • projector devices such as digital projectors
  • digital projectors have found increased popularity as a tool for the presentation of content to an audience.
  • These projectors are typically used to project a computer- generated presentation onto a viewing surface, and allow a user to easily present high-quality, professional appearing images to audiences of a range of sizes.
  • these projectors are now often found as permanent fixtures in conference rooms and other meeting facilities.
  • Some projector devices are configured to enable a user to access a presentation by coupling their computer to the projector.
  • a user must physically connect their computer, such as a personal computer or personal digital assistant (PDA), to the image projector. This process may present issues to the presenter.
  • PDA personal digital assistant
  • connection to the image projector may require numerous cables and/or adapters to enable connection of the user's computer with the available projector. It is not unusual for the cables and adapters to get lost or become misplaced.
  • the first presenter when transitioning from a first presenter to a second presenter, the first presenter must physically connect an image source, such as a computer, to an image projector using the appropriate adapters and cables. The first presenter then typically seats himself or herself close to the image projector. When the second presenter wants to present their presentation, the first presenter may have to disconnect the computer from the image projector, enabling the second presenter to connect a new computer to the image projector, possibly using different adapters and cables. Typically, the first presenter may have to change seats with the second presenter to provide room for the second presenter to connect to the image projector.

  • the depicted embodiment includes a list of projectors, it will be appreciated that it may include other types of image display devices in the list. Examples include, but are not limited to, rear projection display devices.
  • the Status column indicates whether each projector is available, in use, or unknown, although other identifiers could be used, or only a single identifier may be used. If a projector is in use, its name may be grayed out (unless it is the projector the user is currently using). If there is only one available projector in the list, it may be selected by default. A projector's status may be unknown if it is one of the last 5 projectors used but is not on the current WLAN, for example.
  • a projector may be dropped from the list when a beacon is no longer heard and the WLAN settings are the same as when last checked and an attempt to connect to that projector has failed. Otherwise, the projector is left in the list and is unknown. However, a user may also drop a projector from the list manually.
  • the time to listen for a beacon on PC-based devices may be set to approximately 5 beacon intervals (i.e. the time between receiving beacons), while on Mac-based devices the value may be set to approximately 9 beacon intervals, to obtain desired performance.
  • a common listening time may be used for all devices.
  • the MRU list of the last or previously used devices may be updated based on whether a device is successfully used. If so, it may be added to the list. Further, if the WLAN is the same and no beacons are detected, the device may stay in the list with an indicated status of unknown. If the user tries to connect to it and it is not available, an error may be displayed and then the projector may be dropped from the MRU list. [0047] If an available or unknown projector is selected, the Project! in the figure button may be the default button. The Project!
  • button may be disabled if there are no projectors or devices found, or if there is no projector or device selected. Note that, in this example, the user may only select an available or unknown projector; projectors that are in use appear in the list but may be grayed out.

  • an alert dialog may be provided to notify the user that current network activities may be disrupted while the program looks for available devices or projectors, and that the user should close any applications using files on the network. Proceeding past this point dismisses the dialog and replaces it with a progress dialog that may be used to indicate progress in the search.
  • One of three things may then happen (when the user selects a projector or device whose status is unknown): (1) The projector or device cannot be found (e.g., it is out of range or turned off), which may generate an alert dialog as shown in Fig. 6, (2) the projector is found but is in use, which generates an alert dialog as shown in Fig. 7, or (3) the projector is found and is available, which projects the contents of the user's desktop (or some other selected file) on screen.
  • the Scan button may be enabled unless the user is currently projecting. Clicking the Scan button may also cause an alert dialog, followed by a progress dialog as described above. If more presenter-enabled projectors or devices are found, they may also appear on the list. If no more presenter-enabled projectors or devices are found, the progress dialog may be replaced by a dialog which states that no more presenter-enabled projectors or devices were found.
  • a Settings... button may be enabled when an available projector or device, or the projector or device the user is currently using, is selected. Clicking it opens a settings dialog, which may allow the user to adjust various settings, such as, for example: the presenter name, network name, and IP address (the user can either choose to obtain an IP address automatically or specify the IP address, net mask, and gateway).
  • the presenter module's MAC address may also be provided as read-only information.
  • the Settings... button is still available when projecting, but all content of the settings dialog may be read-only to reduce disruption of a presentation.
  • a diagnostics tab may also be provided which may enable a user to blink LED 30 on a projector or image-rendering device to verify a proper connection, and/or restore factory settings. The diagnostics tab may also illustrate the LED location on the projector or device, such as on the image-rendering device (30).

If not, in block 1020, the user interface provides an alert to the user indicating that no other projectors are available. Alternatively, when other networks have been identified, in block 1021 , the user interface provides an alert to the user that there may be a temporary loss of network connectivity.
  • the user may cancel the operation to return to block 1002.

  • the screen in Fig. 12 appears, which shows a list of projectors and/or other devices populated with those found (all boxes may be unchecked by default).
  • the list may be populated with presenter-enabled projectors on the current WLAN, and/or the last n number of projectors accessed.
  • the projectors on the current WLAN may be discovered via the methods described above in the context of Fig. 10, including but not limited to, receipt of a unicast, multicast or broadcast announcement "beacon" from the projector or associated image-rendering device.
  • the "version” information shown in Fig. 10 may be obtained from the "beacon” message (which may contain the version information), or may be obtained by querying the detected projectors and/or associated image- rendering devices. If no projectors are in the list or if the desired projector is not in the list, the user may clicks the Scan button, which operation is described above. The Scan button may result in an alert dialog if any other WLANs are detected, notifying the user that current network activities may be disrupted during the search. If the user clicks OK, a progress dialog may appear. As more presenter-enabled projectors are found, they may appear in the list as they are found (even while the scan continues). When the scan is complete, the progress dialog closes. If no more projectors are found upon completion of the scan, a dialog appears that indicates no more presenter- enabled projectors were found. The user may then check the desired projector(s) and click Update.
