playing from PC against opponents using smart phones?

when you're playing live chess from your pc is it possible that your opponent is playing on his/her phone (using the chess.com app)?

if so (and i'm quite sure it IS so) then i'd like to suggest that there could be a way of knowing beforehand the platform your opponent's using.

i say that because people using mobile devices (phones or tablets) may be playing wile walking, waiting for a bus, watching TV, on work, or in any other situation that may not make tham be able to fully focus in the game (even if they don't realize it).

so if you are playing from a pc and want greater chances that your opponent will be likewise fully focused then knwoing if him/her is playing from a mobile device could be handy.

i know it may sound a trivial and speculative thing, yet i'm sure it would be so easy to implement.
