AR HUD Personalization System (AHPS)

The AR HUD personalization system is designed to help novice drivers to improve the driving
experience and safe driving.

Role

As a novice driver, I find existing HUDs fail to provide precise information for me to make timely decisions. Therefore we propose a personalized HUD system to imrpove efficiency. In this project, I took on the role of UX designer and researcher.

Duration

3 months (Jun.2022- AUG.2022)

Overview

In current HUD systems, the visual display has many limitations. AHPS is designed to give users timely information and to enhance their driving experience.

Team

UI/UX Designers: Junyan Lu, Adele Wang

Tools

Figma, Photoshop, After Effects, Illustrator

Scope

UI/UX, Wireframing, Rapid Prototyping

The Big Picture

Studies have shown that HUD-using group demonstrated better driving performance than the group without. Specifically, in the following areas:

With all of this in mind, it is clear that drivers without HUD are exposed to more dangerous situations while driving. However, There are still areas that need to be improved, such as:

Therefore, it is critical to enhence the existing HUD features to better protect all drivers.

Starting Off

After Identifying the existing features of different HUDs in market, I drafted series of survey and in-person user interview questions.

What are industry standards
and trends? What are
the pros and cons?

What are the painpoints of
current HUDs? How can
we solve them?

What are some
improvements
that I can make?

Competitive Analysis

By comparing the exisiting HUDs in the market, I ventured out and analyzed the pros and cons of current HUD features of different brands.

Strengths

User Interview

Five novice drivers between the ages of 18-30 were interviewed about their driving confidence and use of the current HUD.

Painpoints

Varied needs

Drivers have different needs when it comes to hud visuals. Such as novice drivers, drivers with color blindness, etc.

Info Distraction

Existing HUDs displays too much information at once, making it difficult for drivers to capture the information they need.

Hard to use

Users need to spend a lot of time figuring out a new system for each car, as well as setting it up. Which becomes discouraging.

Prioritization Plotting

Based on the data collected, I drew up a list of potential features. I was able to narrow it down and focus on what was critical to the success of the product. I also came up with some features that we could build in the future.

Meet the Users

User Journey Map

Insight

Easy setup

Mobile app to set up HUD

Information Prioritization

According to their preferences, users can be informed of the information they want faster.

Simplified Information

Provide all information to the driver in a simple and easy way while driving

Information Architecture

Layout Research

Color Research

Low-fi Wireframes

Before embarking onto preliminary user testing and high fidelity mockups, I brainstormed on potential UI designs, illustrating wireframes to get a feel for the app and its core features.

Personalized Prioritization

Information will be displayed in different areas depending on user's needs and in different situations.

Always On

Temporarily On

Hi-Fi Interfaces

HUD User Scenarios

After a survey, we grouped the driving information different users wanted into five categories: road reality information, vehicle speed, warnings, road speed limit, and navigation. Depending on the user's preference, the priority can be adjusted to form different layouts. This allows users to see the information they want to know first while driving.

Scenario Assumption: Long distance Travel
(Real-time Road Information takes precedence)

Scenario Assumption: Commute
(Navigation information takes precedence)

Future Design

Universal Design

After market research, the existing HUDs do not have a color scheme for the visually impaired. There is generally only one universal color scheme, so we are continuing to develop this project in the future and we want to add universal design to help more people improve their driving experience and driving safety.
