Systems and methods for providing a universal platform for at-home health testing and diagnostics are provided herein. In particular, a health testing and diagnostic platform is provided to connect medical providers with patients and to generate a unique, private testing environment. In some embodiments, the testing environment may facilitate administration of a medical test to a patient with the guidance of a proctor. In some embodiments, the patient may be provided with step-by-step instructions for test administration by the proctor within a testing environment. The platform may display unique, dynamic testing interfaces to the patient and proctor to ensure proper testing protocols and accurate test result verification.

A screen sharing system includes a first display apparatus including first circuitry; and a second display apparatus including second circuitry. Both of the first display apparatus and the second display apparatus display an input screen. The first circuitry of the first display apparatus is configured to receive first hand drafted input data that is input to the first display apparatus, and set an edit authority, of a user of the second display apparatus, for the first hand drafted input data. The second circuitry of the second display apparatus is configured to restrict editing of the firsthand drafted input data based on the edit authority of the user set by the first display apparatus.

When a user creates a new video exchange session via an online system, the user specifies an activity for the video exchange session. The activity may specify a name for the video exchange session, as well as other thematic content (e.g., visual effects, backgrounds) displayed via the video exchange session. The online system trains a machine learned model that predicts a likelihood that other users will accept an invitation to join the video exchange session if a certain activity is specified for the video exchange session. The online system may then use these likelihoods to rank and sort the activities for the user or to highlight activities with threshold likelihoods.

Systems and methods for providing ephemeral streaming spaces may include (1) providing a user with a digital display of video cards, in which each video card within the digital display corresponds to a contact, of the user, designated as currently available for video conferencing, (2) receiving user input selecting a video card from the digital display, and (3) in response to receiving the user input, initiating a video conference between the user and a contact corresponding to the selected video card. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for recording a meeting using a retroactive record feature. The present technology provides for improved systems and methods for providing a recording of a virtual meeting, where a selection to initiate the recording from the beginning or an earlier time in the meeting from a current time may be received after the virtual meeting has started. The system may process received meeting content streams to generate a plurality of data segments that may collectively form a meeting recording. Each data segment, for example, may include meeting content associated with a particular user/attendee and associated with a timestamp and/or time duration. In some examples, the plurality of data segments may be stored on a blockchain, which may provide an immutable meeting record that may be concatenated together and made available for playback based on a selection to record the meeting and consent given by the users/attendees.

Examples associated with relationship preserving projection of digital objects are disclosed. One example includes identifying suitable locations within a physical space for projection of digital objects. The digital objects may be stored in a virtual space. A representation of a first digital object from the virtual space may be projected onto a first suitable location in the physical space and a representation of a second digital object from the virtual space may be projected onto a second suitable location in the physical space. The first suitable location and the second suitable location may preserve a spatial relationship between the first digital object and the second digital object.

Examples associated with room capture and projection are disclosed. One example includes an information management module that may maintain information regarding a virtual space and a first digital object within the virtual space. The first digital object may be associated with an artifact in a physical space. A room calibration module may map the virtual space to the physical space using sensors to detect attributes of the physical space. A capture module may record a modification to the artifact to be maintained by the information management module. A projection module may project a representation of a second digital object into the physical space. The representation may be projected based on a signal from the information management module.

Disclosed are a live broadcast stream pushing method and apparatus, and an electronic device. One specific embodiment of the method comprises: receiving viewing permission setting information, wherein the viewing permission setting information is used for representing viewing permission of viewing a live broadcast stream of a multimedia conference; on the basis of the live broadcast starting state of the multimedia conference and the viewing permission setting information, determining whether to push the live broadcast stream of the multimedia conference to a requester who requests the live broadcast stream; and in response to determining to push the live broadcast stream of the multimedia conference to the requester, pushing the live broadcast stream of the multimedia conference to the requester. According to the embodiment, the flexibility of pushing a live broadcast stream of a multimedia conference is improved.

One example method includes receiving, at a video conference server, interaction data representing a plurality of participant interactions in a virtual expo with a plurality of virtual expo elements; storing the interaction data in a data store, the interaction data including a participant identifier, a virtual expo element identifier, and an interaction characteristic; determining one or more analytics for one or more of the plurality of virtual expo elements based on the interaction data; and causing the one or more analytics for one or more of the plurality of virtual expo elements to be displayed on a client device.
