What is it?
Grienna is an instantaneous commuting application that gives its users live feedback on their driving behaviour in regards to the emission outlet created in their car engine. This is made possible by a small sensor-device attached to the cars engine that transmits data about the emission outlet to the application Grienna. The commuting application Grienna was build as the digital representation of the feedback system, also acting as an incentive for making people try the sensor-device.
What I did?
In a two man team we build the prototype Grienna in a sprint of 6 weeks. I curated several brainstorm sessions did user research and designed the interface and interactions. When the prototype was finished we pitched the project at the digital days in Vienna.
