One of the winning teams of a Princeton University hack contest created a devise for sign language users. Ethan Gordon, David Liu and Jeffrey Han took the best hardware design category this past weekend for their ASL Tegra. Using a camera to detect gestures, it translates them into text. Some 600 hackers were challenged to build something in 36 hours during the HackPrinceton event. First place earned team members hard drives, a remote-controlled helicopter and $1000 in cash. There's more details on the event
