U1.07

Shape, texture, and orientation encoding

Cards in this group · 5

  1. U1.07.1Shape is categorical only, and reliably distinguishable shapes are few
  2. U1.07.2Shape judgment needs adequate mark size; tiny scatter dots defeat it
  3. U1.07.3Texture fills are unstable under scaling and printing
  4. U1.07.4Orientation encodes a few ordered values but rotational symmetry confuses it
  5. U1.07.5Shape and texture differences survive greyscale output and colour-vision deficiency
