Abstract: An alert system for alerting a user in a virtual reality environment is provided. The virtual reality environment has a corresponding physical environment that is monitored by a detector of a fire alarm system through an alarm panel, and the virtual reality environment is provided to one or more user virtual reality devices by a central server. The alert system includes a processor in communication with the alarm panel of the fire alarm system and the central server of the virtual reality system and a memory. The processor continuously monitors the alarm panel of the fire alarm system, receives a signal from the alarm panel when an alarm of the detector has been triggered, and disconnects the one or more user virtual reality devices from the central server upon receipt of the signal.

Abstract: Systems and methods of assisting users in collision avoidance in a virtual reality environment include tracking a location of first and second users in a physical environment; based on the tracked location of each of the users, calculating a collision probability between the first user and the second user in the physical environment; comparing a threshold collision probability to the calculated collision probability; and when the calculated collision probability exceeds the threshold collision probability and the first user avatar visible to the second user and the second user avatar visible to the first user do not visually suggest to each of the first user and the second user a representation of the probability of collision in the physical environment, a collision alert is triggered.

Abstract: Systems and methods of assisting users in collision avoidance in a virtual reality environment include tracking a location, speed, and direction of movement of first and second users in a physical environment; based on the tracked location, speed, and direction of each of the users, calculating a collision probability between the first user and the second user in the physical environment; comparing a threshold collision probability to the calculated collision probability; and when the calculated collision probability exceeds the threshold collision probability and the first user avatar visible to the second user and the second user avatar visible to the first user do not visually suggest to each of the first user and the second user a representation of the probability of collision in the physical environment, a collision alert is triggered.
