The referenced article on glanceable reading links to a paper[1] with an interesting result. It finds uppercase text is more quickly recognised than lower case text for individual words. The paper suggests customisable text settings in user interfaces may actually interfere with legibility, although it is not immediately obvious in which scenario this might occur. > The significant interaction between typeface size and case shows that design factors can influence one another, as in this case the taller capital letters assisted readers in quickly distinguishing stimuli presented at a smaller typeface size. Consider, for example, an interface where the user may enlarge or reduce the text size. The present data suggest that this seemingly minor degree of control could have unintended consequences. Reduced lettering height could lead to interactions with other design decisions, and surprising emergent issues. More generally, the customizability of operational interfaces is called into question, as end-users may choose combination they consider aesthetically pleasing, but are ultimately operationally detrimental. 1. http://jdobr.es/pdf/Sawyer-etal-2017.pdf http://jdobr.es/pdf/Sawyer-etal-2017.pdf
