The author discusses key findings of a series of video walks developed as part of her practice-based PhD research (2011–2014). Four video walks were produced for handheld projectors and tested in four different public spaces. The first video walks (The Surface Inside, 2011; I-Walk, 2012) were guided, and only one handheld projector was available. The latter (Walk-itch, 2013; (wh)ere land, 2014) were created for multiple handheld projectors, offering participants a cocreative role. Onsite observations revealed a shift in participant engagement between earlier and later video walks. A threefold method for analyzing audiovisual documentation also emerged during the research.

便携式投影：分析共同创建的特定于站点的视频漫游

作者讨论了作为她基于实践的博士研究（2011-2014）的一部分而开发的一系列视频漫步的主要发现。为手持投影仪制作了四个视频漫步，并在四个不同的公共场所进行了测试。第一次视频步行（The Surface Inside，2011 年；I-Walk，2012 年）是有指导的，并且只有一台手持投影仪可用。后者（Walk-itch，2013 年；（wh）是土地，2014 年）是为多台手持投影仪创建的，为参与者提供了共同创造的角色。现场观察显示参与者参与度在较早和较晚的视频步行之间发生了变化。研究期间还出现了一种用于分析视听文件的三重方法。
