'Show It, Don't Just Say It': The Complementary Effects of Instruction Multimodality for Software Guidance
In an observational study of expert–novice graphic design tutoring, speech, annotations, and remote control each trade precision for learner agency and sense of control over the shared workspace. Teachers mix modalities adaptively, supporting contiguity principles while motivating precision–agency trade-offs and digital territoriality as design constraints for adaptive software guidance.
Supporting Artefact Awareness for Partially-Replicated Workspaces
Cross-reality remote collaboration often yields partially replicated workspaces where artefacts drift out of sync across sites and collaborators lose mutual visibility of manipulations. We outline artefact awareness support so teams retain shared understanding of objects and changes despite asymmetric physical access.
