The primary thread was the relationship between XR interfaces and knowledge work, examined through two contrasting live demonstrations. Frode Hegland showed his Author system running in a headset, visualizing metadata from the ACM Hypertext 2023 conference — people, papers, locations — with selection, layout, and focus controls operated via a spatial toolbar. Ken Perlin then demonstrated two prototypes: a hierarchical Wikipedia page viewer navigable with both controllers and hand gestures, and a semantic zoom demo using Robert Frost’s “Stopping by Woods on a Snowy Evening,” where walking closer to an object progressively reveals its title, full text, and analysis. Sam Brooker introduced the ACM Hypertext 2026 conference (London, September 14–18), themed around “hypertext method” — hypertext understood not just as technology but as a way of thinking: non-linear, networked, dynamic. This framing set the stage for the group’s broader inquiry into how spatial computing might serve scholarly communities.
