The present disclosure encompasses apparatuses, methods and systems for monitoring, predicting, replicating and simulating particle
ray tracing and
interfacing said tracing with alert, response, measurement and entertainment systems or devices in an ergonomic fashion. Among the objectives of this disclosure is to provide related variations to designs that protect, guide, inform, or entertain users or systems. In order to accomplish this feat, the disclosure requires one or more particle
ray observation sensors (PROS), which observe particles and their movement and send a
signal to one or more particle
ray response relays (PRRR), which perform an action in response to a said
signal. Developments from this disclosure can be used to build safety devices that assist users, protect users from danger, assist
dental hygiene, duplicate live music in other real or virtual environments, and help commercial assessors value buildings, renovations or optimal use of space with the aid of
Artificial Intelligence.
