tracking operator's distance traveled on shop floor using arduino

Hello, my name is Ashutosh Akolkar, and I'm a mechanical engg. I'm very new to electronics and arduino.
Being into manufacturing if auto components, I usually face problem tracking operator's movement, from his machine for various reasons.
I would like to use an arduino based product, say like a small arduino with proper emitter and receiver sensor fitted onto his shoes, for example, and track his movement.
Can anyone in this group help me in this activity ?
