A railway signaling system uses digital displays with tightly-spaced characters. If tracking between the characters is excessively reduced to fit more information on the display, which consequence follows?

💡 Explanation

Excessively reduced tracking causes individual characters to merge visually, hindering the reader's ability to distinguish them clearly, thereby decreasing legibility, because the Gestalt principle of proximity is violated. Therefore, legibility declines, rather than search time decreasing which would occur with optimized character spacing.
