The
Apply
button will apply the current setting and will rescale the Visualization window according to the
current setting. The
Clear
button will reset the position drawing.
The sub-steps within the Sensing Area step are as follows:
•
While touching the device, move the hand posture, which is typical for the application, along the
maximum XY positions which the user would like to reach in the application. Repeat the hand
moving along the maximum XY position about ten times to get a more meaningful drawing. The 2D-
signal plot in the Visualization window draws the calculated position based on the hand movement.
It is likely that the real position does not fit the calculated position.
•
Use the slider of the four scaling parameters to reduce the grid size until it fits within the deformed
position drawing.
•
Press
Apply
and check if reaching all XY positions with the same hand movement is now possible.
•
If all positions can be reached, continue with the next parameterization step. If not, adjust the
sliders and press
Apply
again until the positioning meets expectation.
The following graphic shows a typical position drawing and the parameter setting of the corresponding
parameterization step. The grid and thus the scaling are changing with the parameter settings.
