Design process and practices, User experience and General aesthetics.

The display layout should be such that it is organized according to the information content (e.g.,importance,sequence, functionality), is sized manageably (e.g., divided into proper sections), is attention grabbing, and is visually pleasing (e.g., aligned and with restricted use of colors)

Clever designs for taking user input (e.g., raw information or system commands) can improve the overall performance, in terms of both time and accuracy, for highly interactive systems.

Visual Display Layout guidelines avoid cluttered displays, place important items consistently, place important items at the top center and stucture for easy comparison.
