## Routing Note

Primary owner: human-centered-design-kb. This is the foundational primary source for Fitts's law — the cognitive-foundations / motor-control law that underpins target acquisition in interface design. It resolves the previously **To be validated** Fitts (1954) citation in `Wiki/fitts-law.md` (compiled from the Yablonski (2024) secondary source) and is also cited as theory in [[selection-and-control-of-action]]. Provenance note: the file is the 1992 public-domain APA Centennial reprint of the 1954 original; the reprint's own pagination (262–269) is used for page locators, while the formal reference uses the canonical 1954 pagination (381–391).
