Popout

This is a recreation of Figure 5.12 of "Visualization Analysis and Design" by Tamara Munzner, ch 5, p 110.

Many channels support visual popout, including (a) tilt, (b) size, (c) shape, (d) proximity, and (e) shadow direction. (f) However, parallel line pairs do not pop out from a sea of slightly tilted distractor object pairs and can only be detected through serial search.
