Dynamic Displays Flashcards
(32 cards)
Field of Vision
People can only focus on a small field of vision at a time which means they can only see a small section of the panel at any given time.
Frequency of Use
Most frequently used and important displays are close to the line of sight under normal viewing conditions. (Right in front of the user)
Sequence of Use
The order the displays are used because it takes time to move eyes and head to see several displays clearly.
No sequence?
Displays grouped by function.
Link Analysis
Technique used to assist in the design of display configurations.
Link
Connection between a pair of items indicating a certain relation between them.
If a display has a strong link..?
Displays with strong links should be located closer together than weak links.
First Step Link Analysis
Prepare a diagram that shows the interactions between the display components
Second Step Link Analysis
Examine all relations between the displays and establish link values in terms of the frequency of eye movements between the displays
Third Step Link Analysis
Develop an initial link diagram in which the displays are rearranged so that the most frequently used displays are located in close proximity in the central visual field
Fourth Step Link Analysis
Refine the diagram we created in the first step to make the final layout
Motion interpretability
How well a display represents the motion of an object (GPS showing car’s motion)
How to determine the best way to provide motion information?
Consider the frame of reference (GPS shows the car move through a stationary world or does the external world move around the stationary car?)
Head-up Displays (HUDs)
Most commonly used in airplanes and video games (google glass)
Helmet-mounted Displays (HMDs)
Similar to HUDs but without requiring the user to move their head.
Three Types of Warning Signals and
Advisories: general response
Cautions: rapid response
Warnings: immediate response
Warning Signals
Display should show high-priority alert signals.
Near users line of sight.
Flashing easily detected
(Red for emergencies)
Warning Signals and Labels most effective if…
Describe the consequences of noncompliance Have wide, colorful borders Short and to the point Salient and relevant to the user’s goals Presented near the hazard
Warning Signals and Labels least effective if…
The users are already familiar with the object or product to which the warning is affixed
Users do not perceive a risk associated with the use of an object
Auditory Icons
Represents everyday sounds with stereotypical meanings. (Police car siren used for antivirus warning sound)
Earcons
Brief, recognizable sequences of tones to provide information. (Receiving text message)
Three-dimensional Displays
Can be made using auditory localized cues
Dichotic Displays
When each ear receives different auditory information. (headphones)
Speech Displays
Used to transmit slightly more complicated information.
