Overview

There are several Windows within the GASP lab software that display pressure data.

They are Forceplate which has a default position as a tab on the main window  but can be moved or docked to anywhere within the program.  A good position is on the right group of windows. (See image 1)

The second window called the COP window shows the COP as you move through the swing.

Third Window is called balance and this shows right to left (image 2)

ForcePlate Windows

See any of the images above.

There you are able to view the pressure measurement via the color coding to the left.

 

The % pressure on the left toe area Top left in (image1) 38%.

The % pressure on the right toe area Top right in (image1) 59% .

The % pressure on the left heel area bottom left in (image1) 63%

The % pressure on the bottom right area bottom right in (image1) 41%

 

Measurements may be 1 %  out combined as we round each number rather than displaying the decimals.

 

The central number left and right relate to the % of total pressure between the whole of the left foot and right foot.

 

The central X denoted the center of pressure between the left and right foot, with the x between the does and heels showing the COP between them. As the toes and heels more off the pressure system this X will disappear.

 

Configure your pressure plate.

 

Do not stand on the pressure system at this stage

Select the configure icon at the top of the Forceplate window.

You then need to select the FDM option if a right handed player would stand on the system and the white section is plate is near the right foot.(see image of the right player in any of the images above).

If you have the plate the other way around then you should select Rotate FDM.

 

Pressure calculation

 

We recommend that you mark the mat covering the plate with a central position this will avoid having to to use the Set Split Icon which is used to adjust the system if pupils are not stood in the center of the mat.

 

Use the Set Split Position if your pupil is not standing in the middle of the plate to ensure you get accurate reading. Once you select the Set Split Position Icon you can select anywhere in the Pressure plate image to make sure you spilt the horizontal line between the toes and heels and the left and right foot.

 

3D Icon

 

See (mages 4) Once selected the pressure plate image will rotate to show how high the force goes and the pressure readings over the feet. You are also able to move the 3D plate by left Clicking and dragging.

COP Window

The COP trace (center x image 2) show the direction of the movement of the COP.

Manually Synchronizing the force plate with your Video – Once you have adjusted the latency offset in the force plate settings if further adjustment is require you are able to move the force plate data backwards and forward for each clip by using the manual adjust settings in the force plate window.as illustrated below.
