I was unable to find any game that used a proximity sensor like this. 
This is a hypothetical use case that currently does not exist on mobile 
devices. I'm not saying it is not a valid case, just that no one has 
demonstrated this on any mobile device (or even if it would help or not 
better be done with camera tracking).

You can't rely on it because the hand could be bent at an angle (thus 
radiation would be difference at the same distance).

Agree. But can we do them as separate specs? (i.e., "User Proximity" and 
"General Proximity Sensor")?
