Abstract: In a system for determining intent of a detected virtual contact between a user and a virtual object in a virtual reality environment, contact maybe detected between a designated selection device, manipulated by the user, and the virtual object. It may then be determined whether or not the detected contact between the designated selection device and the virtual object is intention. Determination of whether or not the detected contact is intentional may be based on at least one of an approach direction of the virtual contact with the virtual object, an approach velocity of the virtual contact with the virtual object, or an approach acceleration of the virtual contact with the virtual object.

Abstract: Computer-implemented systems and methods are provided for analyzing and determining properties of virtual environments rendered on a display. The disclosed embodiments include, for example, a method for obtaining, by one or more processors, one or more depth parameters comprising one or more display parameters reflecting characteristics of the display, wherein the display parameters include a height and width of the display, and one or more environment depth multipliers reflecting a scaling factor to optimize display performance. The method may also include calculating, by the one or more processors, a diagonal display distance based on the display parameters. The method may also include calculating, by the one or more processors, an environment depth based on the diagonal display distance and the one or more environment depth multipliers. The method may also include setting, by the one or more processors, the depth of the display equal to the environment depth.

Abstract: A system and method of operating an audio visual device generating a virtual immersive experience is provided. The system may include an optical system and a display system received in a housing, and an audio output device operably coupled to the display system, the housing being coupled to a frame to be worn by a user. A sensing device may sense at least one of an ambient brightness level or an ambient noise level, and a control system and processor operably coupled to the optical system, the display system, the audio output device and the sensing device may, in response to an external command to transition between the virtual environment and the ambient environment, adjust at least one of a brightness level or a noise level of the virtual environment based on the sensed ambient brightness level and/or the sensed ambient noise level before executing the received external command.

Abstract: Computer-implemented systems and methods are provided for analyzing and determining properties of virtual environments rendered on a display. The disclosed embodiments include, for example, a method for rendering a virtual environment, the method comprising operations performed with one or more processors. The operations of the method may include generating a plurality of object layers, the object layers representing permissible height values. The method may also include populating the environment with a plurality of objects, wherein each object is associated with a height value corresponding to one of the object layers. The method may also include determining whether any two objects form an occluded pair. The method may also include calculating a cast shadow index for each occluded pair reflecting a magnitude of a height differential between occluding object and the occluded object. The method may also include rendering the virtual environment in accordance with the calculated cast shadow indices.
