Systems and Methods for Collision Avoidance in Virtual Environments

A system of assisting users in collision avoidance in a virtual reality environment comprising:

• a first user virtual reality device at least partially obscuring a first user's perception of a second user;
• a second user virtual reality device at least partially obscuring a second user's perception of the first user;
• a user location tracking system that tracks at least a first user's physical location and a second user's physical location within a physical environment associated with a first user's virtual location and a second user's virtual location within the virtual reality environment, wherein the virtual reality environment uses X, Y, or Z-axis offsets to unbind the scope of the virtual reality environment from the associated physical environment, wherein the size of the virtual reality environment is larger than the associated physical environment in at least one of the X, Y, or Z axes, wherein the X, Y, or Z-axis offsets that unbind the scope of the virtual reality environment from the associated physical environment include at least a first designated origin location that corresponds to a single X, Y, and Z location in the associated physical environment and corresponds to two or more X, Y, and Z locations in the virtual reality environment;
• a processor in communication with each of the first user virtual reality device, the second user virtual reality device, and the user location tracking system;
• and
• a memory in communication with the processor, the memory storing program instructions that, when executed by the processor, cause the processor to:
• present to each of the first user virtual reality device and the second user virtual reality device the virtual reality environment in which, when one of the first user or the second user moves to the first designated origin location in the physical environment, the corresponding first user or second user moves from a first X, Y, and Z location in the virtual reality environment to a second X, Y, and Z location in the virtual reality environment that is offset from the first X, Y, and Z location in the virtual reality environment in one or more of the X, Y, or Z axes altering an initial relationship between the first user's physical location and the first user's virtual location compared to the second user's physical location and the second user's virtual location to an altered relationship between the first user's physical location and the first user's virtual location compared to the second user's physical location and the second user's virtual location, such that when the first user and the second user occupy a single X, Y, and Z location within the physical environment, such that the first user and the second user physically collide, the first user and the second user may occupy two distinct X, Y, and Z locations within the virtual reality environment;
• provide a first user avatar visible to the second user in the virtual reality environment via the second user virtual reality device when the X, Y, and Z location and a relative position of the first user and the X, Y, and Z location and a relative position of the second user within the virtual reality environment suggest visual contact would exist within the virtual reality environment between the second user and the first user;
• provide a second user avatar visible to the first user in the virtual reality environment via the first user virtual reality device when the X, Y, and Z location and a relative position of the first user and the X, Y, and Z location and a relative position of the second user within the virtual reality environment suggest visual contact would exist within the virtual reality environment between the first user and the second user;
• track a location of the first user in the physical environment via the user location tracking system;
• track a location of the second user in the physical environment via the user location tracking system;
• based on the tracked location of each of the first user and the second user, calculate a collision probability between the first user and the second user in the physical environment;
• compare a threshold collision probability to the calculated collision probability;
• when the calculated collision probability exceeds the threshold collision probability and the X, Y, and Z location of the first user avatar visible to the second user in the virtual reality environment and the X, Y, and Z location of the second user avatar visible to the first user in the virtual reality environment 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 not triggered;
• and
• when the calculated collision probability exceeds the threshold collision probability and the X, Y, and Z location of the first user avatar visible to the second user in the virtual reality environment and the X, Y, and Z location of the second user avatar visible to the first user in the virtual reality environment 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, the collision alert is triggered.
