Abstract: The present disclosure provides a user interface process flow for posting content on a display device. The disclosed techniques include a user interface process that initiates a connection that enables a host device to receive content from a guest device in a secure and discrete manner. The host device utilizes one or more graphical elements to invoke a user input at the host device to verify that the user is physically present at the host device. In response to the user input, a server generates a connection identifier that is communicated to, and displayed at, the host device. The connection identifier and an address of a server are displayed at, or otherwise communicated from, the host device to a guest device. The guest device uses the connection identifier to establish a connection with the host device for delivery of content from the guest device for display on the host device.

Abstract: The present disclosure provides a system that enables manipulation of a persistent display of shared content. Content can be shared with a host device from a guest device. A rendering of the content is configured to be manipulated by a user at the host device. For instance, a rendering of the content can be resized, scaled, rotated and moved within a graphical user interface. Annotations can also be added to the rendering of the content. The rendering of the content can also be persistently and automatically displayed in response to a device operating in a predetermined state. The predetermined state can include, for example, a lock screen mode, a bulletin board mode, or a mode when application user interfaces are minimized. The rendering may be removed from a display when the device exits the predetermined state or when the device receives a specific command to remove the rendering.

Abstract: The present disclosure provides a system that controls an interim connection between two computing devices. The system first determines if a person if physically present at the host device by detecting an interaction with an input device attached to the host device. In response to the input, the system generates a connection identifier that is displayed at the host device. The display of a graphical element for communicating the connection identifier enables the guest device to receive the connection identifier. The graphical element can be a Quick Response (QR) code, bar code, text, etc. The guest device can send a connection request to the server using the connection identifier. In response to the request, the server verifies the connection identifier and establishes a data connection between the host device and the guest device. Data can be exchanged between the host device and the guest device via the server.

Abstract: A communal computing device, like an interactive digital whiteboard, can detect the start and end of user sessions with the device. When a communal computing device detects the end of a user session, the it can determine if a personal device that was connected at the start of the user session or during the user session was also connected at the end of the user session. If so, the device can initiate actions based on the session start or end signals such as, but not limited to, transmitting a message to an organizer of a meeting scheduled during the time of the user session, transmitting a message to a participant of a meeting scheduled during the time of the user session, transmitting a message to an administrator, or generating a notification, such as a user interface reminding a user to take their personal device.

Abstract: A technique allows a user to project content onto a shared display region in a controlled manner. The technique involves receiving context information that describes a context in which a user is currently interacting with a local user computing device. The technique then determines, based on policy logic and the context information, whether it is appropriate to invoke a private state, or to remove the private state and enter a shared state. The private state involves presenting a privacy screen on one or more shared display regions. The local user computing device remains connected to the display device(s) that host the shared display region(s) while operating in both the private state and the shared state. According to one advantage, the technique eliminates or reduces the risk that the user will inadvertently release private information to others; further, it does so without asking the user to perform burdensome preparatory actions.

Abstract: A computer-implemented technique is described herein for facilitating a user's interaction with graphical elements, such as emoji characters. The technique entails: presenting a collection of graphical elements on a display surface of a user interface mechanism; presenting a selector mechanism on the display surface that provides a plurality of attribute value options (such as skin tone options); receiving a selection by the user of one of the attribute value options, to provide a selected attribute value; globally modifying at least a subset of the graphical elements in the collection based on the selected attribute value, and displaying those modified graphical elements. In one approach, the technique presents the collection of graphical elements in an array that is capable of being panned along at least a first axis of movement. The technique reveals the selector mechanism when the user pans the array along a second axis of movement.
