Supporting Remote Expert Guidance using Extended Reality in Skilled Hobbies

Image shows an remote expert wearing a VR headset and novice wearing an AR heaset. The expert is able to see the first-person-view of the novice. The expert and novice are talking to each other about how to use a tool (pruning shears in this image).

I’ve conducted participant observation (CHI’20), and user-centered design studies (CSCW’22, Best paper at CHI’23) to understand how to design, build and evaluate systems that enhance the social and instructional experience of remote skill-sharing in expert-novice groups in skilled hobby activities (e.g. gardening, woodworking). Gardening is a useful case to explore design for collaboration in hobbies as it has widespread intergenerational appeal and is viewed as a meaningful activity for individuals, families and communities. For this project, I have built Networked Unity and AFRAME (WebXR) based design probes whose related GitHub repos can be accessed via request.
