Environmental tracking: We know what you're doing
Google secured a patent this week for a technology capable of determining not just where you are but what you're doing based on ambient sounds, temperature, and other environmental conditions. So, for example, your might call Google's 411 service - and thanks to the sounds of the crowd and an announcer, Google knows you're attending a baseball game on a cool autumn night. Google could then serve up a targeted ad, such as a coupon for dinner near the stadium or a deal on sweatshirts at the souvenir stand if the weather drops below 60 degrees. But put to ill use, this technology is great for knowing where you go and what you do when you get there.
