This study investigates the effectiveness of Mixed Reality (MR) warnings for fall hazards, focusing on user perception and the impact of warning size, color, and visual complexity. Using a commercial off-the-shelf MR device, three different warning sizes were displayed in front of a staircase, and data were collected from twelve participants through semi-structured interviews. Findings revealed that while larger warnings attracted more attention, they sometimes became distractions instead. Participants preferred conspicuous colors and medium-to-large warnings but noted the need for these elements to blend seamlessly into the real-world environment to avoid cognitive overload. Additionally, participants expressed a desire for MR warnings in more safety-critical environments, such as road traffic scenarios. These results highlight the need for a balanced approach to MR warning design, ensuring they are noticeable without being intrusive to enhance safety in dynamic environments.
