For example, when the user is using the simulation, positioned such that the positive/increasing y-axis is displayed as a vertical orthogonal to the user’s horizon in the user’s line of sight, the user’s intuitive expectation is to feel gravity pulling in its normal direction. In contrast, sensations of gravitational pull associated with altered position in relation to the user’s y-axis angle of view may assist users in recognizing, encoding, and being cued by certain patterns in fourspace. <BR><BR> <b>Proposal for a Gravitational Translator:</b><br> A circle composed of 180 electromagnets, each capable of pulling approximately 150 kilograms, surrounds a triangular apparatus composed of non-conductive material suspended from an axle running through the electromagnetic circle’s center; the axle is suspended above the ground by tripods some distance from the triangle and circle. The triangle contains a seat, like that of a kayak or sports car; the seat must have a top-grade safety harness. It may also contain a footrest or pedals. A keyboard tray or other user input device is situated facing the seat while six position-adjustable screens of a [Double RainBow Tie Display](https://osf.io/dxjeo/wiki/doublerainbowtiedisplay/) also face the seat. As the angle at which the user rotates along the user’s y-axis view changes, so does the position of the triangle in the circle of electromagnets. For every two degrees of motion through the user’s y-axis visualization, the triangle in which the user is seated will move by one electromagnet. It will perform this motion by powering up the electromagnet toward which the triangle will move and then powering down the electromagnet that had been holding the triangle in place. (Because the triangle is essentially a portion of a wheel on an axle that fits inside the circle of electromagnets, a catastrophic power failure would leave a user returning to the ground after swinging like a pendulum—watch out for whiplash.) Of course, a vertex of the triangle close to the circumference of the circle of electromagnets must be outfitted with its own electromagnet or be magnet-friendly (e.g., a block of iron, cobalt, etc.).
