Abstract: A shared reality system is described here that defines a platform-agnostic format for three-dimensional objects for use with AR and VR and projects these objects into VR and AR worlds that can be seen by multiple users at the same time. Each user can see the same object and the object may contain shared information that an operator of the system wants everyone to see, such as scores, advertisements, offers, or status information. Rather than having separate individual experiences, each user sees the same virtual objects as if they were present in the real world. The format used for displaying the AR and VR content is compatible with a wide variety of device types, so that content creators can focus on their content and ignore platform differences. Thus, the shared reality system makes it easy for content creators to create shared reality experiences across a wide variety of devices.

Abstract: A portable field boundary for field sports such as soccer, football, flag football, rugby, field hockey, ultimate, lacrosse or others is formed of a flexible cord or twine with pennants or flags or other marking devices being permanently attached to the cord to denote appropriate desired points such as corners, goals, goal lines, mid-field, yardage increments or other desired elements. The boundary is designed to lay restingly on the ground with stakes or other anchoring devices used to affix the boundary to the desired surface defining the corners and perimeter of the playing field. The design is lightweight and durable to allow for multiple subsequent temporary applications, retrievals and storage of the apparatus, the duration of a single use typically being a single practice or competition.
