Perspective: Orient and focus

MIT/ CALTECH/Carnegie : voting is worth technology

• Analysis and Engineering?
• Computers designed for tabulation and interaction
– Paper interfaces better and easier?
– not solve the problem with computers and networks?
• Reference Platform?
• Public Policy in a Digital age:

Perceptual
• Graphical
– View ability
• Color, contrast, size,
– Readability (this is)
• Distinctions, lack of distracters, experience
– Distinguishably (this is not that)
• Precognitive, cognitive,
• Feedback
– Proprioceptive feedback
50ms
– Social feedback
3 seconds
– Emotional feedback
30 + seconds

Cognitive Interface
• Short term memory 7 +- 2 ( in 2 d)
• Depth of information 2 or three
• The book that I bought with the other books proceeds…
• Recognition is better than Recall (except when the
stimulus is confusing “red” written in blue
•
syntactic, semantic
• Cognitive load, bored … overloaded
• Precognitive recognition issues

Cognitive Styles

•
•
Verbal/ Visual
Procedural/Conceptual
Myers Briggs
Physical, perceptual, psychological, neurological

Obvious Design problems..
Distinguish ability
– Ambiguity, mislabel
– Alignment
– Viewable height
– Poor audio, labeling on audio (1 …. To select gore 2…. to select Bush )
Effects
– Button association
– Button not viewable
Feedback and Side effects
– Action
– Undo … action symmetry?
– Visual
(x not counted)
– Completion
Validation
– counted
Mechanical
–

–
–
Difficult to pull, push, turn grab or reach
Parallax,
Dexterity, accuracy,
Button pressure

Seeing it all: visualization
• Perspective and focus
• View ability-vs- procedure that is easy to follow

Principled voting

•
No one is trustworthy
We make mistakes with unfamiliar things
Transcription is prone to error
Transportation is prone to error
Hard to make decisions without information
Ted Selker © 2001, MIT
Eliminate people
• Immediate feedback
• No one person, organization, or mechanism in charge
• Personal Intentions matter:
• Consider , review and change their vote without coercion

Reference Platform: Brazil
• Electronic voting; 96, 98, 2000
– 96 Unisys
7% failure
– 98 Procomp
– 2000 Procomp .02% failure 106,000,000 votes
• Trusted Scientific organization
– Create requirements
• Trusted Technical organization
– Create reference platform
• Companies (5)
– Create demonstratable products for bid
• Government election officials
– Create open viewing and decision of vendor

Public Policy in a Digital age:
• Computational Platforms: Simulations, the rhetoric of the future?
• “Mosaic” of opinion and decision;
– Government,
– community,
– school,
– job,
– family,
– recreation,
