Mercedes-Benz User Experience (MBUX)
What is NTG-7?

  •  A new Head Unit for Mercedes Benz cars.

  • Built on the feedback of the previous generation NTG6.

  • Its designed to incorporate multimodal feedback like Voice and Gestures etc.

  •  Across the various functions it allows the hardware to be controlled via UI and touch panel alone.

  • It supports deep integration of 3D interactions and Augmented Reality features.

  •  Zero Layer UI and contextual interactions elevates the overall user experience.

What I did?

Perform a detailed Usability Analysis of new Mercedes-Benz Head Unit display in collaboration with German Design team. The development of the touch display was running in parallel and I was asked to do a detailed UX review and Usability analysis of the software solution. In the given timeline I did the following:

  • Detailed Usability analysis of interactions and features.

  • Competitive Research

  • Usability improvements and suggestions

  • Interaction design for a feature called eAssist

Detailed Usability Analysis 
Competitive research and
Insights into UX
Understanding the users

  • Conducted and gathered insights from user interview sessions.

  • I deep dived into in-car UX and understood the main use cases.

  • Created personas and scenarios to understand the context.

Business Impact

  • Intelligent Zero Layer which goes beyond usability and provides access features and functions based on context.

  • Philosophy of selective monetisation where user can buy the features in the set of custom packages like OTA (Over There Updates) or ADAS banking  on the power of software.

  •  If a user does not want to any package he or she can simply opt out. This takes care of user needs as well as business needs, opening a proper monetisation channel.

  • Plug and play car infotainment software which is flexible to cater to global markets. Based on the demographics any third party vendors can be replaced, for example Spotify to WeChat.
