17. UConnect Touch HMI Development Process CHRYSLER GROUP LLC
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…

18. UConnect Touch HMI Development Process CHRYSLER GROUP LLC
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
~3 year development process
Key Inputs
1) Ease of use
2) Minimize Driver
Distraction
3) Functional
Grouping of Alike
Controls
4) Simple Centerstack
Interfaces
5) Competitive
Benchmarking
6) Dissatisfaction with
UConnect Touch development process is
Non-functioning
Controls the foundation for all HMI interface
development (Cluster, EVIC, Rear Seat
Entertainment, Active Safety, etc.)
