Can you build a consistent accelerometer that does what you want?
If you think about the accelerometer as a little micromechanical arm which is being deflected relative to the laptop by the force of gravity, it makes a lot more sense. When they're falling together the deflection is 0.

But if you allow external communications it becomes very doable (see: GPS system). Also, if you allow another input that tells the device it's orientation wrt. the gravitational field, say a magnetic field sensor, it becomes easy.
- theoh 11y agoIf your accelerometer measures what Wikipedia calls "coordinate acceleration" it's something observer relative so I expect (waves hands) "problems" will arise with measuring in relation to your chosen reference frame at relativistic speeds.
