Nissan car User Interface study
The Gui as we know it Most display 6 icons at a time, but there are exceptions: Menu-based with icons and text
The Object-based interface • Click “Hot Areas” to navigate • Additional ‘picture level’ before text-based menu appears • Swipe to change camera angle • Click OUTSIDE / INSIDE to move in and out of the car • More than one path to certain services are possible
Object-Based interfaceAn example Click METERS Click SPEEDOMETER • Example options • Turn on cruise-control • Set speed limit • Comfort / sport drive
Research questions • Are object-based interfaces more intuitive than conventional menu-based interfaces? • More intuitive =def faster to find services, users find direct path(s) to services • Can users be trained more effectively on one system than the other? • Training =def familiarizing the user with the system • Training via recommendation system while driving • What paths do users choose to find a service? • Via the actual object OR via a proxy
A 2x2 between-subjects experiment Find nearby gas station? Find nearby gas station? Find nearby gas station? Find nearby gas station?
Pedal Area • Trunk • Open Trunk Lever • Dashboard • Trunk • Opens • OUTSIDE Retrieval paths in object-based interfaces • Retrieval path =defchain of navigation steps to reach service, starting from dashboard • Question: If more than one path is available, which path is used? • Hypothesis: Object-inclusive paths are chosen more frequently than proxy-inclusive paths.
