‘I’m driving here!’ Here’s how Google’s self-driving car could talk to pedestrians

Humans are exceptionally clever at communicating from the driver’s seat. We wave our hands, we use our horns and lights, and in some cases, we roll down our windows and speak our minds. Autonomous cars don’t yet have the options that people do, so companies are busy devising creative ways for them to interact with the world outside.

One such company is Google. The multinational tech firm has been granted a patent that details just some of the ways its Self-Driving Car Project could talk to pedestrians. According to the patent, these methods will not only make the vehicle’s intentions clear, they will also determine the correct way to respond to passersby.

The most obvious means of communication that Google’s autonomous cars will use are the ones that we use behind the wheel every day — turn signals, lights, horns, reverse beepers, etc. — only they’ll be controlled by a computer in a driverless car, with a bevy of sensors and cameras determining when they’re appropriate. Google’s other ideas include light-up “walk” or “don’t walk” signs on the car’s body, image displays, and audible signals similar to the ones used at busy crosswalks. Some of the proposals, however, are slightly more bizarre.

“Other types of notification devices may include mechanisms that mimic human behaviors, such as a robotic hand to make gestures or robotic eyes on the vehicle that allow the pedestrian to recognize that the vehicle ‘sees’ the pedestrian,” the patent reads.
