A motion simulator (or "sim" for short) is a stationary base that recreates the feelings of motion produced by an event or experience. Motion simulators can be used to replicate anything from driving a Formula 1 car, to dogfighting in an old World War II airplane.
Motion simulators aim to trick the human brain into believing in an artificial experience. The better the simulation, the more realistic the experience seems. Eleetus aims to blur the lines between simulation and reality.
Range of motion, degrees of freedom, velocity, and displacement are all important characteristics to consider when evaluating the quality of the motion simulator.
Fidelity is a term that describes the precision of the motion simulation. How quickly does the motion simulator react to cues from the software? How accurately does it mimic the simulated experience? All are important when considering the fidelity of a motion simulator.
A simulation is only convincing if there is nothing to distract the user from the experience. Failures are unacceptable in any quality motion simulator.
