Jaguar Land Rover's "projection pod" technology uses lights to cast images on the ground. Those images are meant to convey directions to pedestrians, so nearby people can see what the vehicle intends to do next.
The lights are dynamic, too. The space between the lines displayed on the road will shorten as the vehicle prepares to brake, and that space will expand as the vehicle speeds up. They can also flex to the left or right to announce an upcoming turn.
Removing the human-driver element eliminates the usual method of looking at the driver and waiting for them to either ignore you or wave you past, so JLR's trying to figure out how to make up for that. Its creepy googly eyes were meant to mimic making eye contact with a driver to determine that you've been noticed and accounted for. But since those are creepy as all get-out, this seems like a better solution.
"The trials are about understanding how much information a self-driving vehicle should share with a pedestrian to gain their trust," said Pete Bennett, a mobility research manager at Jaguar Land Rover, in a statement. "Just like any new technology, humans have to learn to trust it, and when it comes to autonomous vehicles, pedestrians must have confidence they can cross the road safely. This pioneering research is forming the basis of ongoing development into how self-driving cars will interact with people in the future."
