Overview

Role UX Research, UX Design               Tools Figma

This project is a Range Rover 5 redesign focusing specifically on low tire pressure and how we can design to let the driver know of this issue in an efficient and helpful manner. I designed around three key design decisions: red only being used for warnings, the warning appearing on multiple screens, and utilizing Hick's law. 

Do you know what this sign is?

If you didn't, you're not alone!

49% of younger drivers and 39% of overall drivers were unable to recognize the TPMS warning symbol in a survey of more than 1,000 U.S drivers.

Problem

"

The National Highway Traffic Safety Administration found that there are nearly 11,000 tire-related motor vehicle crashes each year - many of these accidents are a result of tire under-inflation

"

"

This leads us to the problem...

Drivers need an in-vehicle digital experience that allows for easy access to tire pressure status and related assistance while driving

Research

Slide 16_9 - 23 (1).png

When looking at other automotive designs, I realized that current trends have some similar patterns:

1. The low tire pressure icon is small and in a location that isn't easily viewable

2. The color that it glows in is in a unnoticeable color like yellow 

3. Usually, there isn't any way to know anything beyond that your tire has low tire pressure

Final Design

Key Design Decision #1

Cluster Warning (1).png

Red Only Used For Warnings

The only time that red will be used on any of the interfaces is for warnings/emergencies. In this way, the driver will automatically know based on color that they are being alerted to something that requires attention.

  • Red is the most visible color from a distance; the wavelength of red light is able to penetrate further through fog, dust and clouds

  • No having to decipher, which distracts the driver; they will be able to know based on color alone that there needs to be immediate action taken

Key Design Decision #2

Warning appears on Multiple Screens

App 3.png

To make sure that the warning will be noticed wherever the driver's attention is, I designed it so it would appear on an app as well, not just on the cluster and centerstack.

  • As it is displayed on multiple platforms, it can easily catch the drivers attention and also let them see it without having to physically be inside the vehicle

  • The warning appears on the landing page + shows extended information when the status is clicked. 

  • Currently, Range Rover 5 does not have an in control app. Land Rover has an app but the reviews on the app store are low and mostly negative. Creating an in control app would help with emphasizing warnings and elevate safety. 

Key Design Decision #3

Hick’s Law

HVAC (1).png

Hick's Law: idea that the more choices you present your users with, the longer it will take them to reach a decision.

  • HVAC screen has a limited amount of buttons/options; I limited it to just the ones I believed were essential when adjusting and changing temperature settings

  • Users will not have to go through the hassle of going through multiple buttons to perform the desired action nor rack through a cluttered page of buttons to look for their desired one 

Reflection

This was my first big UX design project so I enjoyed being able to learn more about automobile user experience while sharpening my design skills and learning more about the UX laws. I hope to be able to do more automobile design in the future and explore the various types of automobiles and their range of users.
