I am looking for some help, or even advice as how to proceed.(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to quantify an impulse from a hand (a high velocity low amplitude motion). In attempt to do that, I've tried attaching an accelerometer to my hand.

My problem is, that the values I'd like to calculate as an objective measure of the quality of the motion is speed and distance.

Here is one example of some of the data:

Date, t, Acceleration X (g), Acceleration Y (g), Acceleration Z (g), Acceleration Scalar (g), Speed (m/2)

2015-11-19 07:57:01 +0000, 43.609411, 0.382812, 0.359375, -0.875000, 0.020451, 1.589126

2015-11-19 07:57:01 +0000,43.655306, 0.367188, 0.414062, -0.855469, 0.018872, 1.589993

2015-11-19 07:57:01 +0000, 43.699334, 2.187500, 0.417969, -1.816406,1.873880, 1.672496

2015-11-19 07:57:01 +0000,43.759296, 0.632812, -0.160156, -1.070312, 0.253663, 1.687706

2015-11-19 07:57:01 +0000, 43.804159, -1.003906, -0.941406, -0.929688, 0.660841, 1.717353

2015-11-19 07:57:01 +0000, 43.851403, 0.078125, 0.781250, -0.699219, 0.051362, 1.719780

The calculations I've attempted with this data is as follows:

t0=43,655306

t1=43,759296

dt=0,10399

g=1,87388

a= g*9,815=18,3921322 m/s^{2}

s=(a/6)*dt^{3}=0,003447113 m

I am assuming that distance is a second integral of acceleration

From this I get that the distance of the motion is 3,4mm which sounds implausible.

Is there another way to calculate or use the accelerometer to get the data I need?

I hope you can help?

Sincerely,

Jacob
