IRIS Concept HMI

IRIS is a conceptual infotainment system designed to eliminate the typical driver distractions associated with using multiple devices on the road. It was presented at the Toyota Tech Expo in 2012. 


The team strove to design a system that’s intuitive and easy to learn, allowing for a safer driving experience.

Role & Responsibilities

  • Collaborated with an Industrial Designer to redefine interactions in relationship between physical buttons and soft buttons.

  • Completely re-invented the user experience and interaction based on research and data.

  • Designed an interface that works intuitively with the new users.


Research & Findings

  1. Gained insights observing the everyday behaviors of drivers on the streets. Evaluated research research and data available on NHTSA.

    • Finding: Driver distraction accounts for up to 50% of all accidents in the United States. Multitasking, when using the infotainment system and cell phone, is the main cause of driver distraction while driving.

  2. Re-evaluated the established Toyota infotainment system.

    • Finding: The interface of the current Toyota infotainment system is cluttered with too much information and functions for drivers to safely interact with while driving. Exacerbating the problem, visual cues are separated between different panels and physical controls. As a result, it's difficult for drivers to locate what they need.


Design Improvements


01: New System Structure & Controls for Intuitive Use

We grouped system functionalities into four major categories: Media, ContactNavi, and Settings. Each category has a physical button so drivers can jump across different functions with ease. In addition, the buttons have been moved to the driver' side for quicker and safer access.



02: Smart Duo-Display

A new visual structure was designed featuring a Main Display and a Mini Display. The screen is split between the Main Display, which contains primary information, and the Mini Display, which contains secondary background information. Users can manually choose which function to display on the Main Display by pressing a physical button. However, the system will base on situation and intuitively display primary information on the Main Display and secondary in the Mini Display.

Use Case: A driver is listening to the radio on the Main Display and using navigation on the Mini Display. When the driver receives a phone call and accepts, the system will turn off the radio and swap the navigation to the Main Display for better legibility while talking on the phone and driving, and display the call on the Mini Display.

03: Immediate Access for Maintain Focus On The Road


System Activated Quick Screen

System Activated Quick Screens are generated by the system. For user clarity, they appear on the Mini Display. System Activated Quick Screens include: incoming calls, Bluetooth connection status and requests, and other relevant auto-triggered information. 


User Activated Quick Screen

The User Activated Quick Screen is triggered by a set of on-screen buttons located at the top of the display. These buttons activate a drop-down “quick screen” for speedy task management on the Main Display. For example, your phone and media volume can be accessed from a single location with one tap.


The unveiling of the IRIS was a success and generated significant buzz in the automotive industry. Following the positive feedback, I was assigned to design the AXIS Prototype 17CY, a second-generation evolution of the IRIS Concept HMI.
