In the late 1970s, while at Cornell University, I made our first "cell poker" for studying the mechanical properties of living cells. Another person
made a data acquisition device that accepted simple commands over a serial line. For people to operate this device, we needed software that would
translate a concept such as "poke" into machine actions. We needed the software to output a motor control signal while digitizing the sensor signals,
make graphs of the data, derive the probe force from the position measurements and graph the results, and send the data to the department's mainframe
for archiving and more analysis.
