Driving from southern Italy to Scandinavia is not that difficult. All you need is a car and GPS on your smartphone. But if you have to find something closer and smaller, like a restroom in a shopping mall, chances are your mobile device will be useless. No one knows that better than Domenico Colucci, a 26-year-old computer scientist from Bari, a city in the deep south of Italy. Colucci was named Young Web Entrepreneur of the Year by the European Commission in Helsinki, Finland, late last year. The tiresome experience of taking 30 minutes to get to a much-needed bathroom in a multi-storied supermarket in Milan convinced him that he had to start working on developing a way to make indoor positioning systems more pervasive. Eventually, he found what he thinks is the answer.
