Highlighting
You can achieve better legibility in the work area of a screen by highlighting important or structuring elements. There are several different types of highlighting.
Guidelines
Highlighting Types
From the ergonomic point of view, the possible types of highlighting can be divided into the following three groups:
- Tolerable highlighting that is to be used very sparingly and
only in the case of an emergency (see below) includes:
- Lines as single lines, interrupted lines and double lines
- Intensity
- Hardly tolerable highlighting that is to be avoided, if possible, includes:
- Semi-graphic symbols such as * ! #
- Ergonomically bad highlighting that is not to be used on a screen includes:
- Uppercase
- Spaces text
- Flashing
- Color
Highlighting Usage
The highlighting in the first two groups is to be used only if all means of spatial and conceptual structuring have been exhausted.
As a rule, not more than 10 % of the screen should be extra emphasized. This portion is already exhausted by the lines for groups and lists or tables.
Therefore, try to avoid further highlighting under all circumstances.
