What is HMI @ Chrysler?

Human Machine Interface (HMI)Ergonomics

• Anthropometry• Visibility• Accessibility• Efforts

Cognitive Reasoning• Usability• Functional grouping• Workload management including driver

distraction• Menu navigation• Information processing

Systems Interaction• Evaluate as an environment versus a

component• Feature usage understanding

CHRYSLER GROUP LLCWhy focus on HMI?

Ensure all Interfaces are:• Simple, Intuitive, and Easy to

Use• Fit wide range of Persons• Anthropometry • Base to Tech User• Children to Wiser

Generation

Automotive Environment:

• Significant changes in automotive environment can have a significant impact on customer use cases, importance and frequency of use, i.e. …

– Climate – Very Hot to Very Cold

– Road Conditions – Dirt, Paved, Highway…

– Rural, Urban:

Scalable and Aligned Interfaces:

• Developing a scalable interface that can handle the complexity of automotive feature / hardware line-ups can be challenging:

– Multiple Displays and Control Interaction Pointes

– With & Without Navigation

– With & Without Safety Features

– With & Without Comfort Features

– Etc.

CHRYSLER GROUP LLCUConnect Touch Feedback

Motortrend:  2011 Chrysler 300"the new 8.4-inch touch screen navigation and entertainment system is refreshingly easy to use. In response to customer requests, Chrysler even went so far as to add redundant climate and audio controls below the touch screen for the most commonly used functions"

“Chrysler’s Uconnect controls use a big touch screen with large, clear on-screen “buttons.” Coupled with redundant hard keys for common functions, it is a much easier interface to use than cross-town rival Ford’s MyFord Touch system.”

UConnect Touch has a larger, less complicated touch screen - driver centric, first surface “short cuts” enabling quicker response times in a simple, intuitive, easy to use system…

Current Dodge Journey New Dodge Journey

“UConnect” (hands free) buttons will be packaged on our new corporate steering wheel – driver not required to “lean or glance” for button actuation…

UConnect Touch HMI Development Process

1) Ease of use

2) Minimize Driver Distraction

3) Functional Grouping of Alike Controls

4) Simple Centerstack Interfaces

5) Competitive Benchmarking

6) Dissatisfaction with Non-functioning Controls

Key Inputs

~3 year development process

UConnect Touch development process is the foundation for all HMI interface

development (Cluster, EVIC, Rear Seat Entertainment, Active Safety, etc.)

Design confidence gained from over 1000 non-Chrysler employees’ input through 30+ HMI User Tests that started 3 years prior to Launch – implement Voice of Customer, not Voice of Management
