Contour Bias
n. the prejudice toward natural gestures.
The common understandings of contour biases regularly miss the interactive opportunities. In three dimensional designs we are biased to prefer natural shapes, as in the design of a rounded soap dispenser or curvy car. In the temporal canvas we are drawn to natural gestures. Whether it be through Ux designers or conductors of orchestras, rounded natural motions offer readability over the mechanical or static by permitting the actor a model capable of entrainment and empathy.
