In the article, "Body acoustics can turn your arm into a touchscreen," found at
http://www.newscientist.com/article/dn18591-body-acoustics-can-turn-your-arm-into-a-touchscreen.html?DCMP=OTC-rss&nsref=tech , reported by New Science (NS), the article described the next great stride in man's technological advances, a touch screen on the arm. The key behind this new mind boggling technology is acoustics. "Dan Morris and Desney Tan at Microsoft's research lab in Redmond, Washington exploit the way our skin, musculature and skeleton combine to make distinctive sounds when we tap on different parts of the arm, palm, fingers and thumb," said NS. So now, when someone taps on their arm, an e-mail or phone will appear. (Let's see the teachers take our phones away in class now....) However, what does this mean for society? Now that we are integrating technology onto our own bodies, are we becoming robots? What's next, the ability to program the human brain? We can upgrade the tools we use but we should be careful about trying to influence people's free will.
