Pipeline notes

The summary and note below are generated by the signal pipeline — they are Beyond Desk’s reading, not quotations from the source.

Crowdsourced experiments test seven visual channels (position, length, tilt, area, curvature, luminance, saturation) on four perceptual tasks using primitive stimuli, finding channel effectiveness is multi-dimensional. Rankings shift across tasks; a novel Anchored Harmonic Weber model formalizes discriminability; length excels in accuracy but area in pop-out detection.

Challenges the single-ranking view of chart channel effectiveness with task-conditional evidence, useful for anyone designing dashboards or analytic interfaces.
