What we did:We designed two Augmented Reality visualizations, X-ray and Countdown, to assist cyclists in making crossing decisions at uncontrolled intersections.
What we found:We found that the X-ray visualization ensured faster selection of shorter gaps between cars, whereas the Countdown enhanced the feeling of safety and provided better situational awareness.
Takeaway:Our research demonstrates that Augmented Reality can effectively assist cyclists in navigating dangerous intersections, potentially leading to improved safety and decision-making.
Abstract
Cycling has become increasingly popular as a means of transportation. However, cyclists remain a highly vulnerable group of road users. According to accident reports, one of the most dangerous situations for cyclists are uncontrolled intersections, where cars approach from both directions. To address this issue and assist cyclists in crossing decision-making at uncontrolled intersections, we designed two visualizations that: (1) highlight occluded cars through an X-ray vision and (2) depict the remaining time the intersection is safe to cross via a Countdown. To investigate the efficiency of these visualizations, we proposed an Augmented Reality simulation as a novel evaluation method, in which the above visualizations are represented as AR, and conducted a controlled experiment with 24 participants indoors. We found that the X-ray ensures a fast selection of shorter gaps between cars, while the Countdown facilitates a feeling of safety and provides a better intersection overview.

We conducted a study to evaluate three notification selection techniques—Dwell Time, Gestures, and MAGIC Pointing—specifically for cyclists using Augmented Reality in a simulated biking scenario.
We conducted an outdoor experiment comparing three unimodal warnings for E-Scooter riders using Augmented Reality notifications, auditory signals, and vibrotactile feedback in a simulated environment.
We conducted a user study comparing three order picking assistance systems: textual instructions in German, textual instructions in Finnish, and an Augmented Reality system using a Microsoft HoloLens.
