Why Do Our Sims Move So Much?

Our team is consumed with providing our customers the most realistic motion simulation possible. So why does our simulator move around so much? To get the most realistic feel, wouldn’t it just tilt around as much as real car or plane? With unlimited space yes, but in order to simulate the feeling you get when speeding around in a car or plane in the small area that is possible with a simulator, you must be moved around much more.

Sims MoveAs explained in our earlier post of why our sims have mounted monitors, with limited space, the most effective way to simulate the forces applied to the body when accelerating or decelerating in a straight line is to tilt the user forwards or backwards. This also applies to the centripetal acceleration one experiences when turning in a car or plane, for which the simulator tilts left or right. This generates gravitational forces that replicate the feeling of maneuvering a plane or car in real life, while keeping the simulator’s footprint to a minimum.

Fictitious Forces: The Forces of Reality

When one accelerates in a straight line, they will experience the sensation of being pushed back into their seat (simulated by the backwards tilt). When turning left or right, they will experience an increasing force that pushes them in the opposite direction as they turn more sharply or increase their speed (simulated by a sideways tilt).This concept can be explained by the scientific principle of fictitious forces. As stated by Scientific American, “The forces you feel in a moving car—those that push you back into your seat when the driver steps on the gas or throw you side to side when the car makes sharp turns—are everyday examples of fictitious forces. In general, these influences arise for no reason other than that the natural frame of reference for a given situation is itself accelerating.”** What this means is that when you accelerate or decelerate in a vehicle you feel unseen forces beyond the visible tilting.

We firmly believe that having the simulator angle itself around a central point is the best way to simulate the sensation of motion because it has the ability to put force on your body in the same manner that actually accelerating would. The only difference is that we are replacing the fictitious force, that pushes you in the opposite way of the acceleration, with gravitational force that pushes you in the opposite direction as your acceleration. This is precisely why our simulators must move around so much. Because you can’t actually accelerate, the sensation you get from fictitious forces when actually driving a plane or car must be imitated by some other means.

The movement that our simulators implement to replicate these forces is the ideal solution if you want to have a realistic experience, feeling the sensation of flying a jet or driving a supercar around a race track.

The Advantage of Mounted Monitors

The research and development team here at Eleetus strive to provide our customers with the most immersive and realistic simulator experience. We are constantly advancing the technology not only with our motion engine, but the hardware and software that is built around it. Visuals are a key component in simulation. In non-VR applications, the monitors on an Eleetus simulator are mounted to the moving sled. This allows the monitors to remain directly in the user’s line of sight, delivering a visually accurate and expansive view of the simulated environment.

How Do We Simulate Reality?

With limited space, the most effective way to simulate the forces applied to the body when accelerating or decelerating in a straight line is to tilt the user forwards or backwards. This generates gravitational forces that replicate the physical force of the simulated experience, while keeping the simulator’s footprint to a minimum.

The same basic concept applies to the centripetal acceleration one experiences when cornering in a car. The simulator tilts to the left and right, enacting gravitational forces on the sides of the user’s body. This tilting is not meant to simulate the compression of a car’s suspension as it maneuvers around a bend, rather it imitates the acceleration force that is enacted on the body due to changing direction.

When accelerating linearly in a real vehicle, one experiences the sensation of being pushed back into their seat (simulated by the backwards tilt). When turning left or right, they will experience an increasing force that pushes them in the opposite direction as they turn more sharply or increase their speed (simulated by a sideways tilt).

Maintaining a Realistic Line of Sight

Because of this concept of limited space, the Eleetus simulator tilts up to 20 degrees in each direction to accurately simulate the forces of acceleration. With static screens, the user would have to adjust their line of sight in a way that is unnatural. This does not correlate with what you experience visually when flying an aircraft or driving a vehicle.  It is important that the monitors move with the user and remain stationary relative to the user’s line of sight. This provides a realistic sensation of linear movement as the horizon stays consistent no matter the level of motion.

Physics in Motion

As demonstrated in the following video of F1 driver, Lewis Hamilton, the view from a real vehicle stays steady, even in circumstances of extreme acceleration forces.

Hamilton is experiencing upwards of 6.5 Gs of force on his body from different angles. Despite this, the car stays stable and the horizon does not move up, down, left or right, rather it stays still and constant. With mounted monitors that provide the same steady visuals, our customers can simulate a similar experience for an affordable price.

The Reality of Teen Driving

According to a motor vehicle safety report by the Centers for Disease Control and Prevention, motor vehicle crashes are the leading cause of death for U.S. teens. Lack of driving experience and not being able to recognize hazardous situations are two factors that put teen drivers at risk.***


Partnership with the BMW Foundation

Over the past two years, Eleetus has been working with the BMW Foundation and their Street Survival program to develop a new simulation curriculum that simulates these hazardous situations. The program uses software modules developed by researchers at the University of Iowa and replicates hazardous situations that would be too dangerous for teens to actually replicate and practice on the road.  Through the use of these modules, combined with our full-motion simulators, we are able to accurately simulate the environment created by dangerous situations, and give teens the ability to practice what they’ve not been able to practice before.


Simulation Saves

It is one thing to expect the teens to react to the hazards thrown their way when sitting in front of a computer monitor, but it becomes an entirely different situation when you factor in the high levels of adrenaline that often occur in times of danger. For simulation to be successful, the subject needs to be exposed to a simulated environment that creates an all-encompassing, convincing experience that offers as close an approximation to the real event as possible.  This is simply not possible without full-motion driving simulation. The gravitational forces acting upon a body have a major impact on the brain and how teens react behind the wheel. Providing teens with such a way to practice these dangerous situations has the potential to improve their reaction and give them “more experience behind the wheel.”


It is the hope and intention of all involved that the expansion of this project leads to saving more lives on our roads.

The Eleetus Advantage

Part 1: Patented Motion Technology


One of the biggest advantages to Eleetus Motion Simulators is our patented technology.  Eleetus Motion Simulators use electric motors and a unique pivot point in order to produce our unique motion characteristics.  This patented technology produces realistic motion in a system that is engineered to last indefinitely. The load stays almost completely off of the motors due to the way they interact with the pivot point.  This allows for far greater durability, and a more instantaneous reaction from the motors, which creates a more realistic experience.

While technically a two degree of freedom (DOF) system, users actually get a 5 DOF motion experience with the Eleetus Motion Simulator. The 2 DOF that make up the majority of the experience are the 40 degrees of pitch and roll. However, due to the unique patented geometry of the Eleetus Motion Simulator, users also experience the translational forces of heave (20 inches), surge (16 inches), and sway (16 inches).

With the fulcrum of the motion platform placed in front of the rider, the pivot point can be raised and conical as seen in the figure below.  This moves the rider not only in the rotational plane of pitch and roll, but also in all three translational planes. Simulating more degrees of freedom produces a higher level of fidelity, as our motion platform has more ways to react to different motion inputs from the racing or flight softwares.

Difference in Standard DesignOur patented motion technology has allowed us to revolutionize the motion simulation industry.  With a more realistic experience, Eleetus Motion Simulators offers not only exceptional entertainment, but an advanced learning experience when used in an educational setting.
