Abstract: A virtual object system can orchestrate virtual objects defined as a collection of components and with inheritance in an object hierarchy. Virtual object components can include a container, data, a template, and a controller. A container can define the volume the virtual object is authorized to write into. A virtual object's data can specify features such as visual elements, parameters, links to external data, meta-data, etc. The template can define view states of the virtual object and contextual breakpoints for transitioning between them. Each view state can control when and how the virtual object presents data elements. The controller can define logic for the virtual object to respond to input, context, etc. The definition of each object can specify which other object in an object hierarchy that object extends, where extending an object includes inheriting that object's components, which can be modified or overwritten as part of the extension.

Abstract: Terahertz sensing in this disclosure involves the use of at least one terahertz signal that is transmitted towards an object. At least one return terahertz signal is reflected from the object. The return terahertz signal(s) may be analyzed to determine one or more parameters, such as phase, frequency, amplitude, spectral profile, time of flight (TOF) etc. associated with the return terahertz signal(s). Based on the parameter(s), a portion of the object impinged upon by the transmit terahertz signal(s) and which reflected the return terahertz signal(s), and the state of the object/portion, can be identified. The identification of the portion and its state can be used in eye tracking implementations.

Abstract: The disclosed technology is a system and computer-implemented method for assembling and editing a video program from spoken words or soundbites. The disclosed technology imports source audio/video clips and any of multiple formats. Spoken audio is transcribed into searchable text. The text transcript is synchronized to the video track by timecode markers. Each spoken word corresponds to a timecode marker, which in turn corresponds to a video frame or frames. Using word processing operations and text editing functions, a user selects video segments by selecting corresponding transcribed text segments. By selecting text and arranging that text, a corresponding video program is assembled. The selected video segments are assembled on a timeline display in any chosen order by the user. The sequence of video segments may be reordered and edited, as desired, to produce a finished video program for export.

Abstract: The present embodiments relate to automated memory creation and retrieval from moment content items. In some implementations, the automated memory creation and retrieval system can obtain moment content items from user-designated sources with a single user perspective or multiple user perspectives. The moment content items can be assigned tags and arranged in chronological order. The arranged moment content items can be clustered into memory content items based on clustering conditions. Once memory content items are created, they can be arranged into a memory hierarchy made up of connected nodes. In some implementations, the memory content items are also linked together based on similarity in various dimensions in a memory graph. The automated memory creation and retrieval system can receive search criteria for memories from a user interface and provide the user with memories from matched nodes in the memory hierarchy or linked memories in the memory graph.
