Abstract: A collaborative session (e.g., a virtual time capsule) in which access to a collaborative object and added virtual content is selectively provided to participants/users. In one example of the collaborative session, a user interacts with the collaborative object using hand gestures. The virtual content associated with the collaborative object can be accessed with an opening hand gesture and the virtual content can be hidden with a closing hand gesture. The hand gestures are detected by cameras of a client device used by the user. The collaborative object can be moved and manipulated using a pointing gesture, wherein the position of the collaborate object can be confirmed to a new position by titling the client device of the user.

Abstract: Collaborative sessions in which access to added virtual content is selectively made available to participants/users. A participant (the host) creates a new session and invites participants to join. The invited participants receive an invitation to join the session. The session creator (i.e., the host) and other approved participants can access the contents of a session. The session identifies a new participant when they join the session, and concurrently notifies the other participants in the session that a new participant is waiting for permission to access the added virtual content. The host or approved participants can set up the new participant with permissions for accessing added virtual content.

Abstract: A collaborative session (e.g., a virtual time capsule) in which access to a collaborative object and added virtual content is selectively provided to participants/users. In one example of the collaborative session, a participant (the host) creates a new session and invites participants to join. The session creator (i.e., the host) and other approved participants can access the contents of a session (e.g., which may be recorded using an application such as lens cloud feature; available from Snap Inc. of Santa Monica, California). A timestamp is associated with each received virtual content, and the users are provided with a timelapse of the collaborative object as a function of the timestamps.

Abstract: A collaborative session (e.g., a virtual time capsule) in which access to a collaborative object with an associated material and added virtual content is provided to users. In one example of the collaborative session, a user selects the associated material of the collaborative object. Physical characteristics are assigned to the collaborative object as a function of the associated material to be perceived by the participants when the collaborative object is manipulated. In one example, the material associated to the collaborative object is metal, wherein the interaction between the users and the collaborative object generates a response of the collaborative object that is indicative of the physical properties of metal, such as inertial, acoustic, and malleability.

Abstract: Collaborative sessions in which access to a collaborative object and added virtual content is selectively provided to participants/users. In one example of the collaborative session, a participant crops media content by use of a hand gesture to produce an image segment that can be associated to the collaborative object. The hand gesture resembles a pair of scissors and the camera and processor of the client device track a path of the hand gesture to identify an object within a displayed image to create virtual content of the identified object. The virtual content created by the hand gesture is then associated to the collaborative object.

Abstract: A collaborative session (e.g., a virtual time capsule) in which access to a collaborative object and added virtual content is selectively provided to participants/users. In one example of the collaborative session, authentication of the collaborative object is performed by all of the users to complete the collaborative session. Each user authenticates the collaborative object, such as using a stamping gesture on a user interface of a client device or in an augmented reality session. User specific data is recorded with the stamping gesture to authenticate the collaborative object and the associated virtual content. In an example, user specific data may include device information, participant profile information, or biometric signal information. Biometric signal information, such as a fingerprint from a mobile device or a heart rate received from a connected smart device can be used to provide an authenticating signature to the seal.

The method uses a baseband signal to modulate an optical carrier to generate a modulated optical signal including a plurality of high-order sidebands; the modulated optical signal is divided into two paths which are respectively injected into two slave lasers for high-order sideband injection locking to obtain two locked sideband optical signals; Based on combining and splitting two locked sideband optical signals, the radar transmitting signal and receiving optical signal can be obtained through photo-detection and electro-optic modulation. After coherent detection of receiving optical signal, obtaining the intermediate frequency signal, and detection target information can be extracted from intermediate frequency signal by radar algorithm.

Abstract: In an approach a computer receives a first request from a metadata service to store metadata for a virtual machine (VM). The computer validates the metadata service.
