multimodal car display
Oslo is an in-car navigation assistant that uses directional voice controls, a context-aware dashboard, a heads-up windshield display, and haptic feedback to keep the driver’s eyes and mind focused on the road while navigating.
Setting Design Principles
Current Voice UI Increases Driver Distraction
AAA's study shows how many of today's voice-control driving assistants increases driver distraction and therefore, increasing the cognitive load.
Touch Displays Take Drivers' Eyes Off The Road
Switching from 3D buttons to flat icons requires the driver to take their eyes off the road to know what to press and to register the feedback. In high-stakes fast-moving environments like driving, having such distraction could be very dangerous.
Through our research in the problem space, our team focused on designing a better navigation experience and defined the following 3 Design Principles:
DESIGN PRINCIPLE #1
Minimise cognitive Load
design principle #2
The system should support the driver to
focus on the driving environment
DESIGN PRINCIPLE #3
The system should not draw unnecessary attention to itself
Since we only had 2 weeks to finish the entire prototype, our team quickly dived into ideation after research.

Second round of ideation
Oslo is an in-car navigation assistant that uses directional voice controls, a context-aware dashboard, a heads-up windshield display and haptic feedback to keep the driver’s eyes and mind focused on the road while navigating.
Oslo is contextually-aware and provides feedback at the time needed in a meaningful form to enhance the driving experience for the user.
voice: DIRECTIONAL VOICE CONTROLS
Oslo gives easy-to-understand directions based on landmarks in addition to street names. In moments where sudden turns are required, Oslo's voice will be louder in the direction of where the driver would want to turn to.
Oslo also "lives" in the steering wheel to build trust with the driver by bridging the mental dissonance between the system and the car itself.
visual: CONTEXT-AWARE DASHBOARD
Map directions adjusts its view based on both the stage of the trip and also the incoming directions - ie: showcasing a further distance if the driver will be driving straight for a long time (opposite if there are many turns).
These instructions appear in-between the steering wheel so that the driver can quickly glance at it.
visual: HEADS-UP WINDSHIELD Display
Turn-by-turn timed navigational directions displayed on the HUD so that the driver can keep their eyes on the road.
touch: HAPTIC FEEDBACK FOR SAFETY ALERTS
In the event of an emergency, Oslo alerts the driver through haptic feedback on the steering wheel.

what I would do differently now
Test the readability of the typefaces and font size: Prototyping a car display through a computer screen can hide many pitfalls of the design when it is used contextually. One of these pitfalls would be around font sizes and clarity of typefaces when the display is put at a distance from the driver, which would need to be texted in a car-context.
- More realistic interface: To increase the believability of the system, we would need to make a scaled-out version of the interface so that it could be seen from different angles and to see the car wheel turn.
