Fig 5. Cursor autocorrelation functions for all subjects and all conditions.

For each SNR case, motor-imitation decoder curves are depicted in blue and the pre-computed decoder overlays it in red. Better controllability would be expected to be reflected in faster ACF falloff. In almost every case, falloff was faster for the cursor control using the pre-computed decoder (SNR-case 2 did not follow this trend as reliably—see main text for discussion).
