BMW Assistant

UX Research

Voice interaction is slowly making its debut in the automotive industry as it helps minimise the drivers ‘eyes-off-the-road’ time. With the TU Delft, I helped BMW explore this topic and conducted the user research for their personal assistant. An intelligent, digital character that responds to the prompt “Hey BMW”, and is available in 23 languages and markets worldwide.

Research

We started the project with benchmark research in which we tested several voice assistants. Together with the results of an online survey⁠—in which more than 250 BMW drivers participated⁠—we were able to set the key qualities of the assistant. Fast prototyping allowed us to quickly transform the key qualities into initial ideas.

The ideas were integrated into a mock-up car and evaluated during ten user tests focussed on light- and voice interaction. The PrEmo research tool allowed us to measure the emotions of the participants and showed us that the use of light improved the interaction with the system and even evoked feelings of pride and fascination.

With the insights from the research, we refined the prototype and proposed three final interaction concepts for the new BMW personal assistant:

1. Personal activation

To make it possible for drivers to activate the personal assistant in a quick and easy way we decided to use "Hey BMW” as the standard activation word. By personalising their activation word—for example to “Hey Joy”—drivers can lend even greater personality to their assistant.

2. Cockpit interaction

To make the communication with the personal assistant feel as natural as possible, we decided to enable multimodality cockpit interaction. In this way, BMW drivers can use a combination of speech, gesture and eye movement to interact with their personal assistant, just as they would do in real life. 

3. Pro-active adaptation

To allow for a smart system that adapts to the needs of the driver, the personal assistant is able to apply learned routines in the appropriate context. For instance, “Hey BMW, I want to relax” starts a relaxation programme adjusting the light, music and temperature to the drivers' preferences.

“The BMW Intelligent Personal Assistant will take you onto a journey into a new era of intelligent multi-modal digital experiences.”
