Display of Information Flashcards
Absolute Judgment
The classification of a stimulus when several options are avilable
Combination codes
Uses more than one type of coding in a display to maximize discrimination ability
Analog Display
Has a continuous scale and a pointer
Digital Display
Present information in alphanumeric form
Motion Interpretability
How well a display represents the motion of an object (e.g. GPS car movement)
Frequency of Sensory Displays
Most: Visual or Auditory; Some: Tactile; Rare: Scent and Taste
When to use Auditory Displays
Message is simple, short, no need for recall, events in time, immediate action, visual system of person is overburdened, receiving location has poor lighting, task requires continual motion
When to use Visual Displays
Message is complex, long, needs recall, deals with location in space, does not require immediate action, auditory system of person is overburdened, location is too noisy, task allows limited movement
Static Displays
Fixed and do not change (e.g. road sign)
Dynamic Displays
Change over time (e.g. speedometer)
How well the display attracts attention
Conspicuity
How well the display can be seen
Visibility
The ease with which symbols and letters in the display can be discerned
Legibility
The distance at which a person can read the display
Legibility Distance
The ability to comprehend the meaning of characters in a display
Readability
The property of the message to be unambiguous and include information about consequences if ignored
Intelligibility
The property of the display being constructed of appropriate materials for the environment
Maintainability
A display that uses words, letters, or numbers to convey information
Alphanumeric Display
The number of characters shown over the total area of the display
Overall Density
The density in the region immediately surrounding a character
Local Density
Use of Gestalt organizational principles
Grouping
Extent to which the layout is predictable
Layout Complexity
Display that conveys information using an image
Symbolic Displays
Coding Dimensions
The use of arbitrary features that are coded to specific meanings (e.g. street sign colors)
Relative Judgments
Directly comparing stimuli to each other
Link analysis
The technique used to assist in display configuration design by using links between items
HMDs
Helmet-Mounted Displays
Evokes general awareness of a marginal condition
Advisory
Evokes immediate attention and somewhat rapid response
Caution
Evokes immediate attention and response
Warning
Representational, everyday sounds with meanings
Auditory icons (e.g. police siren)
Brief, recognizable sequences of tones to provide information
Earcons (e.g. text message tone)
Displays that feed different information to each ear
Dichotic Displays
Displays that apply force, vibration, or motion to the user
Haptic Displays
