we are currently working on a new concept for the automotive industry. we are experimenting with a projector on top of a car. I developed in vvvv a patch to project the driving trails. We are getting the data of the steering wheel by a modified mouse attached to the steering wheel.
After prototyping and working on the project we finally presented our project to Audi in Ingolstadt
