  Recent technological advances are enabling HCI researchers to explore
interaction possibilities for remote XR collaboration using high-fidelity
reconstructions of physical activity spaces. However, creating these
reconstructions often lacks user involvement with an overt focus on capturing
sensory context that does not necessarily augment an informal social
experience. This work seeks to understand social context that can be important
for reconstruction to enable XR applications for informal instructional
scenarios. Our study involved the evaluation of an XR remote guidance prototype
by 8 intergenerational groups of closely related gardeners using
reconstructions of personally meaningful spaces in their gardens. Our findings
contextualize physical objects and areas with various motivations related to
gardening and detail perceptions of XR that might affect the use of
reconstructions for remote interaction. We discuss implications for user
involvement to create reconstructions that better translate real-world
experience, encourage reflection, incorporate privacy considerations, and
preserve shared experiences with XR as a medium for informal intergenerational
activities.
