• Word Shape Theory

• It's not true that UPPERCASE TEXT is harder to read than Mixed Case Text or lowercase text.

• ... But people aren't as used to reading uppercase, so they read it more slowly. Also, it's perceived as SHOUTING, so use sparingly.

• Saccade and Fixation

• Our eyes move in quick, sharp jumps as we read text (not fluidly). Our eyes mostly jump forward, but also look backward occasionally. 

• Saccade = when your eye jumpsFixation = moment of stillness
