Distortion/interference measurement device for virtual reality environments

A measurement device and methods for detecting distortion or interference in an environment are described herein. The measurement device comprises a transmitter and a receiver attached to a rigid body such that a position and orientation (P&O) of the receiver with respect to the transmitter is fixed. When measuring distortion, the transmitter transmits electromagnetic waves over one or more frequency channels and measures electromagnetic waves over the channel(s) and a P&O of the receiver relative to the transmitter may be computed. Based on the computed P&O and the known P&O of the receiver with respect to the transmitter, the system determines a level of distortion that would cause the change in position and orientation. When measuring interference, the transmitter does not transmit electromagnetic waves and the receiver measures the electromagnetic waves in the environment. The measurement device is moved to identify locations where the measurements of distortion and/or interference are below a threshold value.
