ACCELEROMETER MOVEMENT VIEWED IN 3D

[DaveK]

I am able to take the digital out-put data (X,Y,Z axis) from my
accelerometer and save it to an Excell file. I can plot the data using
but can't get a real good feel for what is really going on with the
movement of the accelerometer. Is there software that I can down load
this data into, view it in 3D, and be able to se it from different
angles? I would also like be able to view the movement in real-time
also. Ultimately, I would like to compare one person's movement
against another's doing similar tasks. Are there any software packages
or information out there that may lead me in the right for my
particular application? I have limited experience with accelerometer
and for that matter electronics. Any information would greatly be
appreciated.

Just in case you don't already know this, acceleration is the
rate of change of velocity, which itself is the rate of change of
position. So if you want to visualize the motion of the accelerometer
position as it moves in space, you will need to integrate its output
twice: Once to get to velocity, and integrate that to get position.

Integration in the digital world is simply summation of data points.
So the second output point of the integrator is the sum of the
first and second input points, the third output point is the sum of
input points 1-3, and so on.

interpreting the data correctly is 99 percent of the task.

use a simulator that places the accelerator stationary, and uses the data to
perform a graphic dx/dy of the wall planes as time progresses. 3d
visualization can be very helpful in many aspects of device / result
interaction.

you may find it easier to generate many multiple images and create a GIF
file that is easily viewed also. transparency of the bitmaps should be
enabled to allow all planes to be viewable as they are displayed
sequentially

happy fishin!
