Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for authenticating a first computing device to access a secure account. Receiving a request from a second computing device to be authorized to access the secure account. Providing, to the second computing, first data that represents a first machine-readable code for presentation by the second computing device. Receiving, from the first computing device, second data that represents a second machine-readable code as read by the first computing device. Authorizing the second computing device to access the secure account in response to determining that the second data accurately represents the first machine-readable code as sent to the second computing device.

A group study system is described. The group study system allows for students to form study groups with other students in the same class or related classes by utilizing various technologies that make such a system possible. The system provides for an anonymous creation of the study sessions and maintains the anonymity until all students joining the study session participate in the study session. These sessions can be in person and virtual. Hybrid and virtual sessions are becoming more and more important with the increasing presence of online education. This system harnesses technology in an innovative way to do something that was not possible years ago by enabling students to gather in a learning environment with other students who previously did not know each other. Additionally, the system operates to allow crowd sourcing of data for the input of exam data, including date and time of the exam in order to automatically extend exam reminders.

One example method includes receiving, by a video conference provider, an indication of a meeting type of a video conference; obtaining, by the video conference provider, multimedia content associated with the meeting type; receiving a request from a client device to join a main meeting of the video conference; connecting the client device to a waiting room associated with the video conference; and providing the multimedia content to the client device in the waiting room.

A method and system for automatically adjusting a participation queue among multiple participants of a communication session are disclosed, comprising adding contribution requests to speak or share content in the communication session to the participation queue, calculating a participation metric for each of the multiple participants, determining an order of entries in the participation queue based on a comparison of the participation metrics of the respective participants in the participation queue to a determined participation metric threshold, to increase a priority of an entry of a respective participant having a calculated participation metric below the determined participation metric threshold.

Various embodiments of the present invention are directed to an improved group-based communication apparatus that is configured to render one or more workflow interface objects to a group-based communication apparatus in association with an operational sequence set returned by a query. The group-based communication apparatus is configured to detect a workflow trigger event associated with a workflow identifier, retrieve an operational sequence set based upon at least the workflow identifier from a group-based communication workflow repository, initiate the operational sequence set, and cause rendering of one or more workflow interface objects to the group-based communication interface. In some embodiments, the operational sequence sets are associated with a group-defined template.

A method for conducting a video conference includes providing a platform supporting a video conference between a plurality of participants, the plurality of participants engaging in a video conference thereon. Within the video conference, controls are provided to at least one of the participants to upload a document to be signed, the uploaded document viewable by all of the participants. Each of the participants in the video conference may independently control their view of the document.

Video sharing is an important part of information exchanging between people in business and in daily personal life. Video sharing between two or more user devices through a server on the Internet usually will consume tremendous network bandwidth. With the supporting of posting and un-posting operations and the dynamic workspace technology introduced in this invention, a server here can centrally coordinate the dynamic secure video sharing between two or more devices while avoiding itself being a bottleneck for the video sharing.

Improved virtual collaboration environments allow participants in a primary collaboration session to initiate side conversations with fellow participants based on virtual locations of each participant within a virtual collaboration layout. The virtual collaboration layout defines virtual locations of each participant in the collaboration session. If a virtual distance between two participants a below a threshold, the participants are able to engage in a side conversation. Management information is provided to a collaboration session host. The management information indicates, for example, a volume or frequency of communication occurring on each side conversation, or an elapsed time since the side conversation was initiated. The host is also provided with controls that allow the host to issue a warning to side conversation participants, to mute the side conversation, or to change a participant’s position within the virtual collaboration layout, thus changing the participant’s eligibility to participate in the side conversation.

When a first user makes a video call with a second user of the other side by using the video call function, a first state is set as a state in which the enclosure is flatly placed on a first surface of an object, and in which a face of the first user is included within a range of an angle of view AV1 of the front camera C1. In the first state, the mobile information terminal 1 detects a first region including the face of the first user from a wide angle image that is captured by the front camera C1, trims a first image corresponding to the first region, creates a transmission image to be transmitted to a terminal of the other side on the basis of the first image, and transmits the transmission image to the terminal of the other side.

A server or an on-premises computing node accesses a message and a destination tag indicating one or more client devices participating in a conference to receive the message. The server or the on-premises computing node determines a configuration for the message based on a source of the message. The server or the on-premises computing node transmits the message to the one or more client devices indicated in the destination tag to configure the one or more client devices to display the message according to the configuration within a display region associated with the conference.
