In this paper, we report on initial work exploring the potential value of technology-mediated cues and signals to improve cross-reality interruptions. We investigated the use of color-coded visual cues (LED lights) to help a person decide when to interrupt a virtual reality (VR) user, and a gesture-based mechanism (waving at the user) to signal their desire to do so. To assess the potential value of these mechanisms we conducted a preliminary$2\times 3$within-subjects experimental design user study$(N=10)$where the participants acted in the role of the interrupter. While we found that our visual cues improved participants' experiences, our gesture-based signaling mechanism did not, as users did not trust it nor consider it as intuitive as a speech-based mechanism might be. Our preliminary findings motivate further investigation of interruption cues and signaling mechanisms to inform future VR head-worn display system designs.
