Control Theoretic Models of Pointing
summary
Compares four control-theoretic models (McRuer’s Crossover, Costello’s Surge, second-order lag, bang‑bang) against a 12‑participant mouse pointing dataset that records pointing trajectories with position velocity acceleration over time. Finds all models predict pointer position reasonably well but differ in dynamics: continuous models fit some users, open‑loop models fit others, and time-in-open-loop rises with target size, with low‑ID trials showing more variability. Releases the dataset and code; four control-theoretic models demonstrate concrete trade‑offs and complementary strengths.
