Artificial iris responds to light like real eyes
The human iris does its job of adjusting your pupil size to meter the amount of light hitting the retina behind without you having to actively think about it. And while a camera's aperture is designed to work the same way as a biological iris, it's anything but automatic. Even point-and-shoots rely on complicated control mechanisms to keep your shots from becoming overexposed. But a new "artificial iris" developed at Tampere University of Technology in Finland can autonomously adjust itself based on how bright the scene is.
Nokia's Instant Community lets you socialize with those around you without actually meeting them (video)
Talking to people is hard, and talking to strangers? That's, like, really hard. Nokia has a better way: the Nokia Instant Community. It relies on ad-hoc WiFi connections from (Finnish) smartphones to create dynamic communities into which people can join. Once connected, trendy but introverted festival-goers can chat, exchange photos, and even download each other's bootlegs of the very show they're attending! It's the work of the Nokia Research Center along with Tampere University of Technology, and while it's just a prototype at this point, you can get the full walkthrough after the break -- the full, monotone walkthrough.
