Hi all

I am stuck and need to know if there is any type of a device that will solve a
problem that I am working on.

The situation is that I have graphic scans (heart rate output over time) on 8-1/2
by 11 sheet of paper.  I need to translate these graphs into x and y coordinates
for the entire length of the graph.

I can manually, using a digitizing table and a cross-hair input device move along
the line and "click" each time I want to register a point.

What I need to know is there anyway that I can automate this process, because I
really need to obtain "continuous" points.

Is there some type of a "tracking device" that can be taught what a line is and
then follow the line as the chart is re-run through the machine that it was 
originally recorded on ??????  

Has anyone "mickey-moused" any eye-tracking devices to accomplish this ??


Any and all help will be appreciated.
