Get used to seeing more and more places banning Google Glass before it hits retail. While many devices capable of surveillance are available - like smart phones - Google Glass is a bit more stealth-like in how it works.

A Caesars Palace casino spokesman today told Computerworld that people wearing the Google Glass technology won't be allowed in the casino.

"Gaming regulations prohibit the use of computers or recording devices by persons who are gambling," said Gary Thompson, a spokesman for Caesars, in an email. "Therefore, individuals wearing Google Glass would not be allowed to gamble. If they attempted to do so, would be subject to arrest under various state gaming regulations."

Google said every new technology generates new questions, legal and otherwise.

"It's early and we are thinking very carefully about how we design Glass. New technology always raises new issues," said a Google spokesman.
