I was hoping to find something like "5cm", but it looks like "g" is all they offer.
Yes, I meant the amplitude of the seat. I was wondering while this solves reading gauges it doesn't help if you need to operate a switch.
If you know the g's of vibration (force) and the hertz they needed to use on the screen, can't you calculate it? Maybe you also need to know the weight of the passenger as well as the details of their strobe method.
No, you cannot calculate this from that. It is basically a free parameter depending on the shock absorbers of the seat.
