In this project, we explored how we can build interfaces to suitably replace driver cues which pedestrians are used to receiving but will no longer receive as a result of introducing autonomous vehicles on our roads in the not-so-distant future.

Current vehicle-pedestrian interactions involve the vehicle communicating cues through its physical movement and through nonverbal cues from the driver. Our work studies vehicle-pedestrian interactions at a crosswalk in the presence of autonomous vehicles (without a driver) facilitated by the deployment of interfaces intended to replace missing driver cues. We created four prototype interfaces based on different modalities (such as visual, auditory, and physical) and locations (on the vehicle, on street infrastructure, on the pedestrian, or on a combination of the vehicle, street infrastructure, and the pedestrian). Our findings from two user studies indicate that interfaces which communicate awareness and intent can help pedestrians attempting to cross. We also find that interfaces are not limited to existing only on the vehicle.

In this project, we explored how we can build interfaces to suitably replace driver cues which pedestrians are used to receiving but will no longer receive as a result of introducing autonomous vehicles on our roads in the not-so-distant future.

Our work studies vehicle-pedestrian interactions at a crosswalk in the presence of autonomous vehicles (without a driver) facilitated by the deployment of interfaces intended to replace missing driver cues.
