MULTISCREEN IN-VEHICLE

INFOTAINMENT SYSTEM

DESIGN

01. Background

Since the Connected Cars were widely introduced in late 2000, Automakers, Tier 1s, and IT Giants started cramming more and more technologies into vehicles. Latest developments, indeed, gave drivers the ability to take calls, read and send texts via voice, navigate around using the latest maps updated over-the-air, and choose what to listen. Handy you say. To some extend. 

 

Infotainment Systems are often brought to market in form of complicated and information-overcrowded systems.  At its core, here is a design problem to balance, convenience and safety.

02. The Goal

Multiscreen In-Vehicle Infotainment System project aimed at maintaining interaction design simplicity and functions accessibility within existing driver behaviour patterns, keeping in mind the major problem of Driver Distraction and the time Driver's eyes spend away from the road.

Multiscreen In-Vehicle Infotainment System is solving problem of traditional designs, such as crowded interfaces, complicated graphics, and unclear hierarchy. Google and Microsoft material design guidelines were taken as a base on the approach of delivering interactive features and mobile experience 

Tasks

integrate latest technologies to assists driver on the core task of driving

eliminate the interaction with contents unrelated to the core task of driving

minimize the time driver's eyes spend away from the road to 2 seconds

minimize driver's learning curve to complete the task

integrate handhelds and 3-rd party apps 

Approach

Group and prioritize 200+ features 

Split information and features across three (3) screens 

Utilize colors and elements dimensions 

03. My Role

Project Initiator who led the project as Product Analyst and UX Strategist. I coordinated cross-functional team to define, design and validate customer interactions with in-vehicle digital dashboard. I led discovery workshops, gathered and documented requirements, mapped customer journeys, delivered wireframes and designed interactive prototypes to tests and to validate assumptions to conclude experiments

Main Tasks

 

 

Cross-team coordination

Conceptualization and ideation

Scope definition and project planning 

Project vision and business goals alignment 

Design execution and assumptions validation 

04. The Challenge

The entire project is build around pre-set hardware and in-vehicle controls. Software product design, prototyping, testing, and implementation tasks were completed under an extremely compressed timeframe in order to meet customer deadlines, and showcase customer's latest infotainment platform at the top automotive event in Geneva (Switzerland). To meet internal and external deadlines, some functionalities where compromised, and replaced with high quality visual effects.    As timeline did not allow for the ideal upfront planning, developers were put together to working in parallel with designers to develop the base wireframes on spot. In order to assist the development visual designers had to jump ahead rapidly gathering Product Analyst and UX Strategist insights on the critical visuals which had not been created yet

 

05. The Structure

To assist on driver transition and to solve the problem of traditional automotive designs, minimalist, distinctive and clear visual structure along with content hierarchy was applied to reflect existing user behaviour. Horizontal content alignment was applied to simulate familiar consumer electronics mobile interfaces. Most critical information was pulled upfront: Traffic alerts, audio library, most recent contacts, and voice assistant. 3-rd party apps support was brought on top of existing dashboard functionality. In order to fit the 3-rd party apps into the vehicle displays, the content was scaled and graded to the vehicle GUI (aka. Graphic User Interface) standards 

06. The Impact

In order to minimize driver interaction with handhelds while driving, the system architecture is primary focused on accommodating core-task focussed dashboard contents, and merging those contents up with 3-rd party automotive-tailored apps (e.g. Google Maps, Spotify, TineIn, etc.) to keep the person behind the wheel connected to the world and digital media. Selected touch-based interfaces (GUI) commands were replaced with voice interfaces (VUI) to allow for prompt tasks accomplishments. The top time consuming tasks, such as setting up the navigation (45 seconds), select the radio station (42 seconds) or find a record (37 seconds) where accomplished by volunteers who tested the system in 15 seconds per task

Minimalist user interface and visual structure allowing for a critical 2-seconds glance to accomplish a step of the

intended task

1000+

Third party Apps delivering driver-focused infotainment options: Audio-books, digital radio, parking search and booking, gas stations, navigation, etc.

With integrated VUI (aka. Voice User Interface)  most time consuming tasks accomplishment time was reduced from 45 to 15 seconds average
