Here is how you tell:
Screen>Eyes=Almost Instantaneous.
Speaker>Ears=~1ms*[feet away from the speaker].
This looks like it calculates reflexes, but this is an interesting idea.

@lv0404 Not everyone has the brain for programming... You need a good sense of logic. I know what I'm talking about. Trying to teach programming classes as optional classes to people in other fields of study showed me that fact. Students struggling to understand the concept of a for loop or even variables.

The advantage of the bluetooth dongle is that you do not need to connect the cable every time you want to update your program in the NXT. When your program is 100% okay you do not need the cable any longer and you can turn off your computer if you want. I found that connecting the cable every time is sometimes a hassle because I could not reach the NXT that easy in some of my models.

@lv0404 Thanks! Also, do you think if I get one I should get the BlueTooth dongle or is the USB cable supplied enough? Is there any difference? Like, do I have to have my NXT plugged in to my computer all the time while it's on, or only for syncing the files?

Well, not everybody has the brains for programming. But I guess you could go for it!

@lv0404 Ok so it is easy to build and program?

For this to work it needs to be configured to account for the difference between the speed of light and the speed of sound, the distance your eyes and also your ears are from the object and for a super accurate reading it needs to measure the air pressure. Nice idea though.

You are talking nano-seconds here... I'm afraid the NXT has a accuracy of less then a milli-second though...

Isn't it just to hold the Enter btn to get 0 ms reaction time? ;)

Ahhh, good point! Well, when you do this you will hear a buzzer and the delay time will be increased by some extra random number of seconds. These seconds start counting after you released the button. So when you hold it down you will have no score at all.
