Core Concepts
Wearable AR concepts offer a promising solution to enhance interaction between autonomous vehicles and pedestrians, reducing cognitive load and improving safety. The study highlights the importance of user-initiated communication and the potential of wearable AR in complex traffic scenarios.
Abstract
The study explores novel wearable AR concepts designed to assist pedestrians in multi-vehicle scenarios. Participants favored sending crossing requests to AVs over passive detection systems. Factors influencing adoption included costs, data privacy, technical defects, liability risks, maintenance duties, and form factors. Wearable AR was perceived as exciting but unfamiliar, with concerns about reliance on eyewear and potential technical issues. The combined approach of visual cues provided extra security and increased confidence in interactions with AVs.
Key points:
Wearable AR offers flexibility in crossing locations compared to fixed infrastructure.
Concerns about cost, data privacy, liability risks, maintenance duties, and reliance on eyewear hinder adoption.
User-initiated communication provides a sense of control and accuracy in interactions with AVs.
Clear communication mechanisms with AVs influence perceived safety.
The combination of visual cues enhances confidence and security during street crossings.
Stats
Three distinct communication approaches were tested: aggregated response (AR crosswalk), distributed response (AR overlay), and both types combined.
SUS scores ranged from 74.48 to 85.31.
NASA-TLX scores ranged from 13.99 to 21.35.
Trust scale ratings ranged from 4.82 to 5.83.
Quotes
"Wearable AR is like having mind control over stopping cars."
"I feel safer using the pedestrian push button because it's something I'm used to."
