Hack.Stuttgart Hackathon by Daimler

Hack.Stuttgart was a hackathon by Daimler from 8th to 9th April 2016. I was focused on the topics “Smart Home & Mobility” as well as “Health & Mobility”. I participated with a team from PionierGarage in Karlsruhe. The hackathon was the first of its kind from Daimler, starting a global series of hackathons in China, India, and the US.

Our Idea: Road Joy

The idea of my team was to measure stress and adapt the settings of the car accordingly to allow for a stress free ride. To achieve this, the car includes a system called “Road Joy” which measures stress levels with smartwatches. When in “Road Joy mode” (comparable to Sport and Sport+ modes) and if the stress levels of the passengers rise above a certain threshold the system decreases the automatic acceleration, enforces a higher distance to the car ahead, and decreases the throttles responsiveness. This way, we try to shift the drivers attention to a stress-free driving behavior.

The Hackathon: Working prototype and 3rd place

During the hackathon we implemented the stress detection with a heart rate monitor because no team-member was in possession of a smart watch. We then used the heart rate to infer a stress level based on the average pulse and the standard deviation. With these stress levels it was possible to adapt the stress reduction measures accordingly. For demonstration, we developed a virtual head unit that displays the measured stress levels and shows the inferred settings. My part was to implement the backend which receives the heart rate, infers a stress level, and computes the stress reduction measures.

In the end, we had a fun weekend, many laughs in the team, and won the third place. I would like to thank Daimler for the great time, the provided hardware, and the insightful mentoring.
