Authoring site-specific outdoor augmented reality (AR) experiences requires a nuanced understanding of real-world
126
+
contexts to create immersive and relevant content. Existing ex-situ authoring tools typically rely on static 3D
127
+
models to represent spatial information. However, our formative study (n=25) identifies key limitations of this
128
+
approach: models are often outdated, incomplete, or insufficient for capturing critical factors such as safety
129
+
considerations, user flow, and dynamic environmental changes. These issues necessitate frequent on-site visits and
130
+
additional iterations, making the authoring process more time-consuming and resource-intensive.

To mitigate these challenges, we introduce <spanstyle="font-variant: small-caps;">CoCreatAR</span>, an asymmetric
134
+
collaborative authoring system that integrates the flexibility of ex-situ workflows with the immediate contextual
135
+
awareness of in-situ authoring. We conducted an exploratory study (n=32) comparing <span
136
+
style="font-variant: small-caps;">CoCreatAR</span> to an asynchronous workflow baseline, finding that it
137
+
enhances user engagement and confidence in the authored output while also providing preliminary insights into its
138
+
impact on task load. We conclude by discussing the implications of our findings for integrating real-world context

A: In-situ: “Hmm no [the boombox] is still floating. Let me capture… [in-situ uses 3D Snapshot]”. Ex-situ, highlighted: “Ah now I can see it all. Should I put it on the pavement like this? [ex-situ moves boombox]”. In-situ: “That's good, yeah.” B: In-situ: “Maybe we can put [the map] here! [in-situ uses Surface Draw]”. Ex-situ, highlighted: “Perfect [...] Is this upside down? I can't really tell.” In-situ: “No that's the right way. [ex-situ aligns map with wall] Yeah, great.” C: Ex-situ: “Capture behind you so I can get more of the walls there so I can align [the garlands].” In-situ: “Okay, do you need 3D image or coarse mesh?” Ex-situ, highlighted: “Coarse mesh, for now. I don't need, like, full color, I just need a bit of the geometry [in-situ users Coarse 3D Mesh]”. D: In-situ: “Can you put the wine bottle like, here? [in-situ places 3D Cursor on the table]” Ex-situ, highlighted: “Hmm let me see, it's a little tricky [ex-situ moves wine bottle]” In-situ: “Yeah that's good!”" class="text-center"
