cognitive amplification

increased resources

high-bandwidth hierarchical interaction

parallel perceptual processing

offload work from cognitive to perceptual system

expanded working memory

expanded storage of information

reduced search

locality of processing

high data density

spatially-indexed addressing

enhanced recognition of patterns

recognition instead of recall

abstraction and aggregation

visual schema for organization

value, relationship, trend

perceptual inference

visual representations make some problems obvious

graphical computations

perceptual monitoring

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

large issues

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

medium issues

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

small issues

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
