A Page is the area that occupies the entire viewport of the screen during its current state. It organizes information while considering:

Mobile Display Elements

Message Display Characteristics

Legibility: Refers to the ease with which the elements (letters, numbers, symbols, etc.) can be detected and discriminated from one another.

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.

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).

Pleasurability: (branding, compatibility, appropriateness, experience) Good user experience, consistent with the visual character of the surrounding architecture, appropriate ‘style’ to the activity, emotional and aesthetic benefits.

Comprehension: Understanding the meaning of a given display so that an associated consequent course of action is both apparent and possible. Comprehension involves recognition as a necessary but not sufficient condition.

User Characteristics

Looking and Finding: Detection and Discrimination. Detection: Determining the presence of an object, target or symbol.

Descrimination: Determining that differences exists; discriminating between target objects and non-target objects is determining differences on the basis of which identifications can be made.

Identifying: Identification: Attributing a name or meaning to some object target or signal. Discrimination and identification are often parallel processes, but in psychological terms they make different demands of the presented information.

Recognizing: Recognition: Determining whether objects in the display have been seen before. Identification often accompanies recognition.
