What is Information Design?

Presenting information about motion, process, mechanism, cause and effect.

How do we present information in a way that:

Clarity and Excellence in thinking = Clarity and Excellence in Data

Graphics reveal data.

Some examples:

Graphing Data

The use of abstract, non-representational pictures to show numbers (statistical graphs invented around 1750-1800).

Graphs allow us to reason about quantitative data. (They can also be misused.)

An excellent chart by Minard (1869) shows the relationship between the size of Napoleon's army as it marched on Russia in 1812, the obstacles it was forced to overcome and the times, places and success with which these obstacles were met.

Transport Maps

London Underground map, designed by Harry Beck in 1933 achieves a reduction of complexity through:

Too much reduction makes the representation too abstract and reduces understandability.

Of course mapping is a fantastic information display mode in many contexts!

Challenger Disaster

The space shuttle Challenger exploded, 73 seconds after launch, on January 28, 1986, killing the seven astronauts on board.

The shuttle failed because two rubber O-rings leaked fuel.

The O-rings lost their resiliency because the ambient temperature was very low.

Before the flight, engineers knew of the problems of O-ring damage with low ambient temperatures and recommended that the shuttle not be launched.

Was the information presented in a way that did not make the engineers claims clear?

Road and Transport Signage

Comparison of different signage systems.

 

Swatch Watch

Design style outweighs utility and functionality. A multitude of designs allows personalization for the buyer. The same methodology has been applied to a number of consumer products. (Swatch website)

Air Traffic Control System

Original design used a single colour vector display.

Extensive colour research allowed designers to come up with a perceptually-based system to help ease fatigue and draw operators' attention to critical data.

Do a web search to find out what these displays look like. Here is good example.

Web Examples

Crime Mapping

Thinkmap web site (Java)

Fuse98 web site (DHTML)

History Flow (WIKI / Wikipedia content diagram)



This lecture's key point(s):

Presenting information in ways that reveals the information content clearly and encourages analysis can have often critical advantages for multimedia design.
