Message Display Characteristics
Legibility: Refers to the ease with which the elements (letters, numbers, symbols, etc.) can be detected and discriminated from one another.
- Font Design
- Upper/lower case
- Letter height
- X-height
- Stroke width/weight
- Letter/line spacing
- Contrast
- Illumination/luminance
Conspicuity: In addition to involving legibility, it also implies other display characteristics. It is nicely summed up by the notion of signal/noise ratio–the ease with which a given piece of information is detectable in the presence of other competing information.
- Design presentation:
- Spatial coding (grouping)
- Shape coding
- Color coding
- Temporal coding
- Size coding
- Pictograms, maps, images
- Attention/target value
Readability: In the display of messages we can affect another property of the message– its readability–by the actual choice of words, the sentence structure and the appropriate language(s).
