For example, when a word is presented at the precise moment it was sung, it was perceived as being too early or too late. Careful treatment on timing led to enhanced perception of simultaneity between the visual and aural. Another concern was readability of temporal typography. Unlike spoken language which can be heard from any direction, a reader's eyes have to focus on the words to read them. The composition was designed to visually flow from one word to the next, priming the reader to attend to the space where each word would appear.
Readability is also an issue when typographic forms change and move over time.
For example, in three-dimensional space, type forms may become distorted depending on the perspective and view angle. The text can even disappear when viewed from its side. Depending on the speed of the word as it moves across the screen, the word may not be perceptually distinguishable. To solve this problem, techniques such as blur were explored to enhance the readability of moving type forms. In addition to addressing the issues, our design goal was to create an overall visual narrative that enriches the inflection, tone of voice, mood and meaning of the lyrics sung.
