Overview

What is iDrive 8.5?

The iDrive 8.5 is BMW's latest infotainment system, featuring a sleek curved display and intuitive touch, all designed to elevate the driving experience.

Problem Statement

How might we redesign the BMW iDrive 8.5 system to help drivers reduce cognitive load while interacting with the car dashboard intuitively and efficiently?

Problem Space

1. Over-complicated climate control

Overcomplicated climate control with a cluttered UI, nested menus, and multi-step clicking.

2. Confusing Media Control Interface

Media controls feel clunky, and simple tasks require unintuitive navigation. For example, the music playback page does not have a pause button.

3. Overwhelming All Apps menu

The "All Apps" menu is also overwhelming, as it displays too many options at once with an outdated UI.

Persona

Dashboard Redesign Concept

Redesign #1: All apps Comparison

Flattened icons were used to replace the current 3D icons, and a mono-color was implemented for highlighting instead of gradient colors, as gradients were found to be distracting for drivers. The bottom control bar was also refined with an improved hierarchy.

Overall, the UI was given a more modern feel, making the entire layout more concise and clear.

A new seat control icon was added to the bottom climate control shortcut, enabling users to directly view and adjust seat heating and cooling levels intuitively. This reduces the cognitive load for drivers.

Redesign #2: Media Comparison

According to the user interview I conducted, people were complaining about the inefficient usage of the layout. For example, the music playback screen lacks a pause button.

In the redesign, the control hierarchy was flattened, reducing the steps to access a favorite song from five taps to two. A different layout was implemented to increase screen space utilization. The general UX of the existing Spotify app was followed, with the addition of a "Shuffle Play All" button to quickly shuffle and play songs from all existing playlists.

Redesign #3: Climate Control Comparison

In the existing dashboard on the right, auto and manual modes are shown in two very different UI and controlled by a rocker switch button. Steering wheel heating can be turned on and off in the auto mode, but can not heat and cool the seat.  

My redesign consolidates the control in different modes and presents everything needed in a single intuitive experience. Driver can access the climate control from the bottom shortcut. When not in auto mode, airflow direction can be manually selected. Other controls such as steering wheel heating and defrost can be quickly accessed through the icons on the left. This design better utilized the screen space and reduced driver's cognitive load by reducing the search and interaction time.

Service Design

Customer Journey Map

This customer journey map outlines the various stages and touchpoints a customer experiences when interacting with our car service and maintenance offerings. The map highlights several pain points and opportunities for improvement.
One notable pain point is during the "Preparation" stage, where customers may feel inconvenienced due to the need for service interruption. This could be caused by factors like long wait times or complex scheduling processes. Addressing this pain point could help reduce customer frustration.

Service Design Blueprint

Through creating the service design blueprint, I got a clear view of the key touchpoints and interactions that make up the customer experience for the car maintenance service. The different stages the customer goes through, from receiving the service alert all the way to retrieving their car after the work is complete. 
By understanding these backstage elements, I can identify opportunities to streamline workflows, improve communication, and ensure the supporting systems and processes are optimized to deliver a seamless experience for the customer.

The dashboard will show details about the maintenance alert and provide ways for the users to schedule services. If users tap the app button on the dashboard, a QR code will be popped and users can scan it to directly jump to the scheduling page on the app. 


The redesign prototype of the scheduling experience via the mobile app, which doesn't currently exist. Users can conveniently select what service to perform, time of the appointment, and review the information or provide notes before scheduling. Within just simple 4 steps, a maintenance appointment can be scheduled. This could greatly reduce the anxiety caused by these maintenance alerts.

Competitive and Comparative Analysis

The competitive and comparison analysis matrix provides a helpful overview of the key services and offerings from several leading auto service centers, including the dealership. This analysis considers factors like service quality, scheduling options, and wait options. Each service provider has its own unique strengths. Some, like Jiffy Lube, specialize in oil changes. Others like Firestone stand out for its full-service maintenance and repair capabilities. Dealership service centers provide manufacture-specific service but could cost more.

What I learned

Through this project, I started diving into Human Machine Interaction design, and I found it so different from what I was used to, such as mobile apps or web design. It requires the interface to strip away anything non-essential and prioritize immediate, real-time interactions and present critical information in a clear and glanceable way. It gaves me a deeper understanding of interactive design fundamentals and how to create interfaces that are tailored to the user's needs and environment.

Service design is important because it offers a transformative perspective that extends beyond screen-level interactions. Through it, I gained a holistic view about user experiences, mapping entire customer journeys across multiple touchpoints and understanding how backend processes, and organizational systems inter-connect.
