Intel’s second Ultimate Coder Challenge is underway, with seven developers putting their abilities in Perceptual Computing application development on the line. Since last week, the contestants have been working to build the “ultimate app” using the Lenovo Yoga Ultrabook™ and Intel’s Perceptual Computing SDK. The developers have seven weeks to create their cutting-edge applications and are blogging about their experiences on the Ultimate Coder Challenge portal. Four influential tech bloggers are also guest posting to provide guidance during the competition and will judge the final applications in April.
