Microsoft's Kinect hasn't had many good video game titles come out and even then, only a handful are interesting to hardcore gamers. Make that less than a handful if you hate dancing. But it's interesting tech nonetheless, and Microsoft is pushing to have it have a life outside of gaming.
According to an article in the Financial Times, "Hundreds of commercial applications are under development for the $150 motion-sensing camera, ranging from aiding surgeons in operating theatres to selling cars....Microsoft has been working on a pilot programme with more than 200 companies for use of the Kinect across 25 industries, from healthcare to education, advertising and the automotive industry." The article points out that Toyota has already created a "virtual showroom," and a separate program allows doctors to explore patients' records on PC by just waving their hands.
According to Microsoft's CFO, the widespread interest comes from the device's relatively low price point, $150 -- two years ago, the in-development project still cost between $30,000 to $40,000.
But I guess this means you shouldn't find it strange if, the next time you're standing in a grocery checkout line you have to wave your arms around to scroll through menus, and talk to the screen to try and process your payment.
