Colophon
The table is set in Dahlia for display and Josefin Sans for text. It is a static site: every page is rendered ahead of time, and nothing about you is measured, stored, or sent anywhere. There are no cookies and no analytics.
Content is authored in Airtable and pulled into the site as a snapshot, so the table does not depend on any service staying up. This edition holds 118 elements and 6 sources, last synced 10 July 2026.
Second edition, 2026. First published 2021 as an undergraduate thesis.
The notation
Every tile carries four marks. A dot (•) means the value has not been recorded yet.
Dimensionality
How many degrees of freedom the interaction carries — from a single axis of text to the extra channels layered over direct experience.
- One-dimensional
- Two-dimensional
- Three-dimensional
- Four-dimensional
Temporality
Whether the interaction resolves in an instant or unfolds over time, and whether it can be said to end.
- Discrete, single-step
- Discrete, multi-step
- Continuous, finite
- Continuous, infinite
Discoverability
What a person must invest before the interaction becomes available to them.
- Immediately apparent
- Apparent on inspection
- Learned by demonstration
- Learned by instruction
Accessibility
Whether the interaction has an equivalent path for people who cannot perform it as designed.
- Has an equivalent path
- No equivalent path
