Method of activating and deactivating a screen saver in a video conferencing system
First Claim
1. A method of controlling a screen saver process in a video conferencing system comprising:
- detecting when a presence exists in an area where the video conferencing system is sited in a predetermined period of time and detecting when a video conferencing session is in progress;
activating the screen saver process only when no video conferencing session is in progress and when no presence has been detected for the predetermined period of time; and
deactivating the screen saver process when initiation of a video conferencing session is detected.

Abstract
Activation and deactivation of a screen saver in a video conferencing system is based on detected presence of a person in the room wherein the video conferencing system is sited and the current status of a videoconferencing session. The video conferencing system processes a screen save message received from an operating system and informs the operating system not to launch the screen saver if the video conferencing system detects that there is an active video conferencing session or if a presence detection technique has detected a presence in the room or area wherein the video conferencing system is sited within a predetermined time period. When a videoconferencing call is connected or a presence is detected and the screen saver is active, the screen saver is terminated. The presence may be detected by motion, sound, or other techniques.

6. A video conferencing system including a screen saver process, the video conferencing system comprising:
-
a presence detection subsystem to detect when a presence exists in an area where the video conferencing system is sited in a predetermined period of time; a conferencing subsystem to detect when a telephone call or a video conferencing call is initiated; and a control subsystem to activate the screen saver process when no presence has been detected in the predetermined period of time according to the presence detection subsystem and when no video conferencing session is in progress according to the conferencing subsystem; wherein the control subsystem is adapted to deactivate the screen saver process when initiation of a video conferencing session is detected by the conferencing subsystem or when the presence is detected in the area by the presence subsystem. - View Dependent Claims (7, 8)

- 9. An article comprising a machine readable medium having a plurality of machine readable instructions, wherein when the instructions are executed by a processor, the instructions cause a video conferencing system to detect when a presence exists in an area where the video conferencing system is sited in a predetermined period of time and when a video conferencing session is in progress, and to activate a screen saver process when no presence has been detected for the predetermined period of time and when no video conferencing session is in progress, and to deactivate the screen saver process when initiation of a video conferencing session is detected or when a presence is detected in the area.

12. A method of controlling a screen saver process in a video conferencing system interacting with an operating system, the method comprising:
-
receiving a request from the operating system to initiate the screen saver process; determining if a video conferencing session is in progress or if motion occurs in an area where the video conferencing system is sited in a predetermined period of time in response to the request; signaling the operating system to allow launch of the screen saver process when no video conferencing session is in progress and no motion has occurred in the predetermined period of time; and signaling the operating system to inhibit launch of the screen saver process when a video conferencing session is in progress or motion has occurred in the predetermined period of time. - View Dependent Claims (13, 14)

15. A method of controlling a screen saver process in a video conferencing system corresponding to the current operating context of the system comprising:
-
inhibiting the screen saver process from executing when the video conferencing system is in use for a video conference; activating the screen saver process when a human presence is detected in a room where the video conferencing system is situated for a first predetermined period of time followed by a second predetermined period of time of no motion being detected; deactivating the screen saver process when a human presence is detected in the room and the screen saver process is active; and automatically deactivating the screen saver process when an incoming conference call is detected and the screen saver process is active.

16. A system comprising:
-
a screen saver process to display an image on a display; an operating system to send a screen save message to top level windows of the system to verify that launch of the screen saver process is acceptable and to launch the screen saver process after a predetermined time period has elapsed in which no user input event is detected; and a video conferencing system, the video conferencing system including a conferencing subsystem and a presence detection subsystem, to process the screen save message, to instruct the operating system to inhibit launch of the screen save process when the conferencing subsystem detects that there is an active video conferencing session or when the presence detection subsystem detects a human presence in a room where the system is sited within a predetermined time period, and to instruct the operating system to activate the screen saver process when the conferencing subsystem detects that there is no active video conferencing session and when the presence detection subsystem detects no human presence in a room where the system is sited within a predetermined time period. - View Dependent Claims (17)
