    摘要： A user may only log into an education application using login credentials of a third-party social media site. A browser is redirected to a server computer of the site which authenticates the user's credentials. The server confirms to the education application which displays its contents on the computer and allows the user to access the education application. Or, the user selects a mobile application on a telephone which connects to the server of the site. The site authenticates the user's credentials and sends a confirmation back to the mobile application. The mobile application connects to the education application and allows it to display its contents on the telephone. Alternatively, an actual minimum number of links is required before access is granted to the education application which is greater than a stated minimum. Attempting to log into the education application with fewer than the stated minimum results in a warning message and access is not granted. Attempting to log into the education application with greater than the stated minimum but fewer than the actual minimum results in a different warning message and access is not granted without further verification.

    摘要： An application delivers educational, entertainment or work-related content including videos and documents to any computing device of a user via an account, each account being uniquely identified. Upon each login, the application checks whether the user is already logged in on another computing device and issues a warning or logs out the new device. The application also checks all user accounts periodically to determine whether one account is logged into more than one computing device. Each video or document is associated with a course and has a corresponding course code. An institution database lists courses that a student is currently enrolled in. Another database records videos watched or documents viewed via a student account. Each student account is allowed a maximum number of courses or is limited by the courses in which they are actually enrolled. The application checks whether the videos watched correspond to more than the courses allowed and if so, then access by the student account is blocked.

    摘要： One or more users log in to a video conference with a shared, online electronic whiteboard and draw upon a shared whiteboard. Each user has a video and audio stream that are sent to a recording server. Data describing each drawing action upon the shared whiteboard is sent to a database server and each action is then distributed to all users to update their whiteboards. Screenshots of the drawing actions are created by emulating a browser and inputting data describing each action from the database. Alternatively, screenshots are taken by each user computer (after each action or periodically) and sent to the recording server. Audiovisual manipulation software is used to create a whiteboard video from the screenshots are then combined with the audio and video streams to create a resulting video of the entire session. A video clip is created simply by sending begin and end timestamps during the session.

    摘要： Various techniques are disclosed for facilitating a computer-supported collaborative session that includes at least two participants using different computing devices to view a canvas that is configured to contain objects added by one or more of the participants. The computer-supported collaborative session is configured to permit participants to mark and/or edit selected objects presented on the canvas. Participants may use a mobile device camera to capture images or video clips, and post the captured images or video clips to the canvas by emailing or text messaging the captured image to a designated email address or phone number.

    摘要： Once participants participate in a video conference the state of information during that video conference is retained for those participants. At a future time, when those participants again meet in a video conference the state of information that was retained is retrieved and presented for them again in the subsequent video conference based upon their identifiers. Information such as the whiteboard, the chat window, shared files, camera settings, images, background, video recording, etc. are retrieved and automatically presented in the new video conference. Alternatively, a participant may be asked if the state of information from a previous video conference should be retrieved. When a participant joins a conference, the current participants grant permission or not for the current contents to be viewed by the new participant. When a participant leaves the conference, or when they all leave, a triggering condition saves the state. Participants may join in a cross-platform conference and all content from a session in another platform is retrieved. Virtual reality may also be used.
