What sports use technology (or technological aids) in officiating?
We all know that several sports use technology to review and back-up the human officials. Instant replay in football and hockey, for example. But what sports can you think of that use technology to actually determine (or help determine) the call of a play live as it happens?
The two I can think of off the top of my head are:
* bowling – a machine determines when pins are down. (Ironically something a human could do with absolutely no problem and no controversy)
* racing – a machine determines down to the thousandth of a second how long it took the runner/driver/skier/etc to get from the start line to the finish line.
Can you think of others?
