A good first impression is extremely important. It makes the difference between impressing a user thinking or making no impression at al. One of the first things drivers will see in their cars is the IVI user interface. Modello is an open source HTML5 UI proof-of-concept designed specifically for today's IVI systems and serves several purposes for Tizen IVI. In addition to demonstrating how an effective IVI UI could be laid out, Modello is also a test case for Tizen web APIs and performance. It can even be used as a way to quickly prototype new UI elements or applications. In this presentation we will to show what Modello can do today, give insights on what it will be able to do in the future, and demonstrate how developers can expand it further for their own projects.
