These guys are getting scarier by the moment.
The patent says: "User dialogue (eg from role playing games, simulation games, etc) may be used to characterise the user (eg literate, profane, blunt or polite, quiet etc). Also, user play may be used to characterise the user (eg cautious, risk-taker, aggressive, non-confrontational, stealthy, honest, cooperative, uncooperative, etc)."
The information could be used to make adverts that appear inside the game more "relevant to the user", Google says.
They always make it sound like invasive tech is "good for the user", how long before this is used to pump adwords revenue?
