thats how gyro's calculate the the position from rate, although that might get a bit tricky(er) taking the second riemann sum , would have to come up with way to find the constant definitively.
While the theory is sound, this is impractical with an accelerometer. Even the integration of gyroscope signals accumulates error over time due to the limitations of the noisy signal and the discrete Riemann sum. Accelerometers are even noisier, from any vibrations, and also easily saturated. You also have to deal with errors in orientation, so computing just velocity, let alone position, from an accelerometer signal is not that easy.
