See my post about the conference and workshop this paper was discussed at, here.
We can't work as effectively when walking as when we're sat at our desks, and we still won't be able to once AR glasses are lighter, and mobile input better developed.
Part of the problem is that our attention is divided between walking and our virtual tasks, with our focus disrupted to navigate obstacles and way-find.
To make AR on-the-move a reality, we need to not only think about glasses weight, battery, and input techniques, but we also need to design interfaces that subtly support us as we walk, improving our focus, rather than dividing it further through notifications and alerts.
This CHI'26 I had opportunity discuss this, among various other challenges & opportunities, during the workshop titled "Next Steps for Augmented Reality On-the-Move", where we looked towards the future of AR interaction, and how we, as a research community, can get there.
