Running a Trace Test
You can use the Trace test to verify that your pen and finger presses register over the entire surface of the
interactive screen.
To Run a Trace Test
1. Press the Trace button, or select
Board > Trace
to display the Trace window.
A trace window appears over top of the main message window. This window shows you the precise x, y
coordinate points that correspond to points of constant or intermittent contact with the interactive screen. This
window provides you with a visual counterpart to the x, y coordinates that are generated in the main message
window (see page 8) when you touch the interactive screen.
2. Touch the interactive screen and drag your finger or pen around the screen.
In the Trace window, you’ll see the points of contact either as segments, dots, or dotted segments.
3. Use a pen tray pen (not your finger or a dry-erase marker) to draw a pattern that includes:
–
a rectangle around the edges of the screen.
–
two diagonal, straight lines that intersect in the center of the screen.
–
a large circle in the middle of the screen.
4. Look for breaks in the pattern where the interactive whiteboard didn’t register the pen’s touch.
–
If you see any breaks in the pattern, try drawing in that area again. If there are no breaks on your second
attempt, the interactive screen is fine.
–
If the breaks remain, make note of all of the system settings to help diagnose the problem.
NOTE:
If you encounter a problem, you should also save an image of the trace pattern. You can capture it to
Notebook software using the
Screen Capture
tool.
5. Close the Trace window.
If you see any problems with the interactive whiteboard’s touch screen, escalate the problem to your next level
of technical support.
