A method, apparatus, system, and article of manufacture provide the
ability to utilize fingertip tracking technology during the course of a
medical examination. A sensor is mounted on a fingertip of a finger of a
first person. Such a sensor is communicatively coupled to a computer to
record measurements. The sensor is calibrated using a known target. The
finger having the sensor is then engaged to perform a medical examination
directly on a second person. Measurements are obtained from the sensor on
the fingertip during the medical examination. Data is obtained (e.g., via
calculations or interpolation) based on the measurements.
