Interaction Modalities for Notification Signals in Augmented Reality

Toward AI-enabled augmented reality to enhance the safety of highway work zones: Feasibility, requirements, and challenges

“…Despite the abundance of literature on digital warnings in general, a significant gap exists in the research regarding warning designs and modality in AR environments in the context of real-time safety systems for Vulnerable Road Users (VRUs) [38]. The majority of previous studies [39], [40], [16] have focused mainly on in-vehicle AR warnings, leaving a gap in understanding how to effectively design AR warnings for workers and other VRUs.…”
