cognitive amplification[edit | edit source]

increased resources[edit | edit source]

high-bandwidth hierarchical interaction
parallel perceptual processing
offload work from cognitive to perceptual system
expanded working memory
expanded storage of information

reduced search[edit | edit source]

locality of processing
high data density
spatially-indexed addressing

enhanced recognition of patterns[edit | edit source]

recognition instead of recall
abstraction and aggregation
visual schema for organization
value, relationship, trend

perceptual inference[edit | edit source]

visual representations make some problems obvious
graphical computations

perceptual monitoring[edit | edit source]

compact presentation
multiple attributes simultaneously
range/distribution/outliers stand out
recognize patterns, clusters, gaps,
interaction
  • select, filter, group
  • multiple coordinated windows

8 golden rules of info vis[edit | edit source]

large issues[edit | edit source]

choice of services, intended users, ease of learning, range of exploration, etc.

medium issues[edit | edit source]

use of color, window management, interaction techniques, choice of widgets, data quality, etc.

small issues[edit | edit source]

terminology, label placement, color, fonts, etc.

  1. categorical data
  • provide appropriate high quality data for intended users
  • simplify learning, prevent errors, enable shortcuts
  • support exploration with proper widgets
  • coordinate multiple windows
  • strive for consistent terminology, color, fonts, etc.
  • ensure label clarity, complete legends, full titles
