The second session at Connect 2006, Innovative Multimedia Applications, had several interesting applications but the most compelling for me was an application developed by Kallideas SpA (in English) in Milan in partnership with Rietek SpA. The application is called Virtual Girlfriend and is best illustrated in this video.
Kallideas is the application provider using their avatar technology. Reitek provides the mobile video technology to get this running on mobile networks. As an application that appeals to individuals, especially to teenagers, this is a natural for your 3G mobile – frequently a teen has only shared access to a family PC, but sole possession of their mobile phone.
