How does a tri-axial accelerometer measure velocity?

tri axial accelerometer

Hi,
I'm doing a project to do with measuring velocity of an athlete.
I'm looking into using a wireless tri axial accelerometer.
I can't seem to find enough detailed information into how it works.
Could you please help!

recordings from accelerometers

Hi,
I'm currently using an accelerometer and it gives me data on a chart.
The acceleration is plotted on the graph and the max acceleration is shown aswel.
My main aim is highlight the max acceleration and show this figure without the graph on a monitor.
For example, my accelerometer gives a max acceleration of 9m/s, i want just this figure to be displayed on a monitor.
How can this be done or is it even possible?
Regards!

Hi,
I'm doing a project to do with 3D motion tracking.
I have looked at numerous websites into how motion tracking is done but only a brief description is given. Can anyone help me out with a detailed description into how 3D motion tracking is done?
Regards!

Are you constrained to using an accelerometer for the motion tracking, or can you use some other means? Does the tracking have to be self-contained on the person, or can part of it be something like a video camera mechanism tracking the motion? What are the constraints of this project?
