In-car entertainment has gotten a little more surreal on the back of some Toyota innovation that sees passenger car windows transformed into interactive sketchpads.
Toyota has revealed an augmented reality system that is has been working on with the Copenhagen Institute of Interaction Design that turns a window into a touch sensitive screen that interacts with the outside world.
The car-maker's new technology, dubbed 'Window to the World', allows passengers to draw images onto their windows that interact with the scenery outside the car. In a demo video from Toyota's Belgian wing, a child is shown drawing a tree which then tracks along the window and out of view as the car begins to drive.
This is just one feature of a host of more impressive technologies, with the ability to zoom in sections of scenery by drawing and stretching a square on the window and pinpointing distances of landmarks.
It's not all in the windows either - a virtual constellation feature crops up on a panoramic roof display, pointing out star patterns and displaying information about them.
It's still a concept, first put on show last month at the Autoworld Museum in Brussels, but it does give a keen glimpse at the future of in-car entertainment and augmented reality.
