Safeguard: Preventing drowsy driving accidents in EVs

Digital Product Design | UX / UI

Context

I was tasked with designing a new feature for an fictional EV car company named XENOS. I decided to focus on driving safety, after conducting 8 user interviews I decided to focus on mitigating the risks of drowsy driving.

328,000

Drowsy driving crashes occur in the U.S. annually

He is a young professional who lives in a very busy city, therefore he spends a lot of time commuting to work. This is what a typical day in his life looks like:

This is Safeguard

I was responsible for prototyping in Figma the Safeguard app feature, this included the Emergency and Prevention modes.

Emergency Mode

​The EV owner will have their car app and they will set up this feature as shown in the video, they will have the option to customize:

​

  • How this mode will automatically activate in the car:

    • Leveraging EV cameras to detect driver nodding off​

    • Leveraging biometrics from smartwatch to monitor drops on HR

    • ​

  • How they prefer the vehicle to "react" to wake them up

    • Seat vibration, sound alarm, or both​

​

The alerts are designed to activate instantly and wake you up to avoid accidents.

Prevention Mode

​The owner will also have the option to set up and customize a "prevention" mode, they will have the option to select:

​

  • How this mode will automatically activate in the car:

    • Detecting "long" drives - the use will be able to define how much time should pass before activating

    • Sunset to sunrise - the user will be able to determine certain hours where they prefer the mode activated

    • + similar futures to the ones in the emergency mode 

​

  • How they prefer the vehicle to "react" to keep them energized during their drive

    • Music preferences, temperature preferences, calling a friend

​

The responses are designed to keep the driver alert and energized!

Learnings

Mapping the E2E Experiences

I was able to learn how to effectively  leverage frameworks like 5 E's of Service Design to map and design the full experience and identify the screens required for every step.

User testing with mockups

I learned the importance of rapid interaction testing through mockups. This helped me quickly identify where users struggled the most and change the interface to make it more user friendly for the high fidelity prototype
