When users want to control Google Glass, they have to first tap on the device and then say "OK Glass" before instructing the high-tech eyewear to do something, such as take a photo or send someone a message.
That command will also surprisingly work with Apple's Siri voice assistant, a feature on the latest versions of the
I tried the command on Siri in a variety of ways -- telling her to play a song, look up restaurants, and asking it how far we are from Neptune -- and the Apple voice assistant responded perfectly each time.
About the only time the command didn't work was when I quietly said "OK Glass, tweet my location." Siri misinterpreted what I said as "Okay glass treatment location" and pulled up a number of glassware stores. And of course, Siri was unable to take a picture or shoot a video when I asked it to, as I could if I was using Google Glass.
So if you want to feel as if you own one without having to pay $1,500 for the device, play with Siri -- and make sure to do it before Apple decides to gag it.
