Eye tracking technology offers great potential for improving road safety. It is already being built into vehicles, namely cars and trucks. When this technology is integrated into transit service vehicles, employees, i.e., bus drivers, will be subject to being eye tracked on their job. Although there is much research effort advancing algorithms for eye tracking in transportation, less is known about how end users perceive this technology, especially when interacting with it in an employer-mandated context. In this first study of its kind, we investigated transit bus operators' perceptions of eye tracking technology. From a methodological perspective, we introduce a mixed methods approach where participants experience the technology first-hand and then reflect on their experience while viewing a playback of the recorded data. Thematic analysis of the interview transcripts reveals interesting potential uses of eye tracking in this work context and surfaces transit operators' fears and concerns about this technology.

翻译：眼动追踪技术在提升道路安全方面展现出巨大潜力。该技术已被集成至各类车辆（特别是轿车与卡车）中。当此项技术应用于公共交通服务车辆时，相关从业人员（即公交车驾驶员）将在工作中接受眼动追踪监测。尽管当前已有大量研究致力于推进交通运输领域的眼动追踪算法，但终端用户（尤其是在雇主强制使用情境下接触该技术的群体）对此技术的认知仍缺乏深入探讨。作为该领域的开创性研究，本文首次探究了公交驾驶员对眼动追踪技术的感知与态度。从方法论角度，我们提出一种混合研究方法：让参与者亲身体验该技术后，通过回放记录数据引导其反思使用体验。对访谈记录的专题分析揭示了眼动追踪技术在此工作场景中潜在的应用价值，同时凸显出公交驾驶员对该技术存在的忧虑与关切。
