Abstract: A notification device that gives notification of predetermined information can be used more conveniently. A notification device includes a state detecting section, a guidance notifying section, a determining section, and a notification control section. The state detecting section sequentially detects a face state of a subject on the basis of images which are sequentially input.

In a case in which the determining section determines that the state corresponding to the notified face guidance information is satisfied, the notification control section controls the guidance notifying section such that another face guidance information different from the notified face guidance information is notified.

Abstract: An augmented reality device receives beacon signals within a geographical area from beacons that facilitate determining a distance between the device and a respective beacon. The device sends beacon-related signals indicative of the beacon signals to a server, which determines the area of the device. The server determines markers within the area of the device, and sends marker signals and augmented reality content associated with the markers to the device. The device scans the area and outputs content associated with a marker it identifies based on the marker signals. As the device enters subsequent areas, it receives additional beacon signals from additional beacons, sends additional beacon-related signals, and receives additional marker signals and content. If there is insufficient storage space on the device to store the additional marker signals and content, the device deletes previous marker signals and associated content. The device stores the additional marker signals and content.

The computing device may place or overlay a 3D virtual object on the physical object in AR based on a predefined location relation between the 3D virtual object and the 3D model of the physical object, and further, generate a composite view of the placement or overlay.

Abstract: Methods are disclosed for providing alternate reality (e.g., virtual reality) representations to users. Exemplary methods employ data collections (e.g., stacks) which affect the virtual representations of baseline virtual models. Data collections contain layers which contain deltas. The deltas specify modifications to the baseline virtual reality world or model. The deltas may be geocoded, while the layers that contain them may not be geocoded. Separately selectable layers are used to temporarily modify or substitute baseline data or virtual elements (e.g., virtual objects) that are ultimately presented to a user on an output device. Conflict resolution algorithms harmonize conflicts between layers of a collection.

Abstract: Presented here is a system and method to increase the speed of computation of a volumetric scattering render technique. The volumetric scattering can include path tracing which simulates interactions between a virtual ray of light and a volume. The interaction can include reflection of the virtual ray of light of a particle within the volume. The system can obtain a threshold number of interactions between a virtual ray of light and a three-dimensional object through which the virtual ray of light is traveling. As the system performs the simulation, the system can compare a number of the interactions to the threshold number. Upon determining that the number of interactions is equal to or exceeds the threshold number, the system can terminate the simulation and approximate interactions between the virtual ray of light and the volume using a second rendering technique that is computationally less expensive than simulating the interactions.
