Abstract: Various methods and systems are provided for authoring and presenting 3D presentations. Generally, an augmented or virtual reality device for each author, presenter and audience member includes 3D presentation software. During authoring mode, one or more authors can use 3D and/or 2D interfaces to generate a 3D presentation that choreographs behaviors of 3D assets into scenes and beats. During presentation mode, the 3D presentation is loaded in each user device, and 3D images of the 3D assets and corresponding asset behaviors are rendered among the user devices in a coordinated manner. As such, one or more presenters can navigate the scenes and beats of the 3D presentation to deliver the 3D presentation to one or more audience members wearing augmented reality headsets.

Abstract: Various methods and systems are provided for puppeteering in augmented reality. Generally, an augmented or virtual reality device for each user generates a virtual 3D environment comprising a virtual representation of a physical room and a 3D asset. An author can record a 3D path for a puppeteering animation of the 3D asset using a 3D interface. At the same time, a coordinated rendering of a corresponding 3D image moving along the 3D path is updated among author devices substantially in real-time. Distinct states of the 3D asset can be assigned to different portions of the 3D path, and authors can set behavior parameters to assign template behaviors such as obstacle avoidance, particle effects, path visualizations and physical effects. The behavior parameters are distributed among presenter and audience devices, and a coordinated rendering of an animation of the 3D image corresponding to the puppeteering animation is triggered.

Abstract: The disclosed technology is generally directed to mixed reality devices. In one example of the technology, a mixed-reality view is caused to be provided to an operator, wherein the mixed-reality view includes both a real-world environment of the operator and holographic aspects. The operator is enabled to navigate among a plurality of steps of a task, such that for at least one step of the plurality of steps of the task, while the operator is navigated to the step of the task: the mixed-reality view is caused to include at least one instruction associated with the step. The mixed-reality view is caused to include a hologram at a real-world location in the real-world environment at which work associated with the step is to be performed. The mixed-reality view is caused to continually include a visual tether from the instruction to the real-world location.

Abstract: Programmability of the data background patterns used to test random-access-memories (RAMs) is accomplished by adding to the memory input/output (I/O) buffers of RAM memory, for each data bit of a data background pattern to be programmed, a programming mechanism and a selection mechanism. The programming mechanism is capable of programming a data bit of the data background pattern in accordance with a programming information signal provided to the RAM. The selection mechanism provides either the programmed data bit or a normal, application data bit to an input/output buffer of the RAM in accordance with whether the RAM is in a test mode or a normal operating mode, as indicated by a test control signal provided to the RAM.
