Forms of influence
Forms of influence
Persuasion Inducements
Exchanges of money, goods, or
services for actions by the person being

A pop-up window or a hyperlink may be
purposefully deceitful (example)

The PSD Model
• Persuasion Postulates
• Persuasion Context
– To discern opportune and/or inopportune
moments for delivering the message(s)
• Persuasive Features
– To implement actual SW features

Persuasion postulates
① Information technology is never neutral
② People like their views about the world to be organized as consistent
③ Persuasion is often incremental
④ Direct and indirect routes are key persuasion strategies
⑤ Persuasive systems should be both useful and easy to use
⑥ Persuasion through persuasive systems must always be unobtrusive to a user’s primary tasks
⑦ Persuasion through persuasive systems should always be transparent

• Recovery statistics
• Posture change reminder
• Dietary rhythm rehearsal
• Diet planning
• Circadian rhythm
Of course. But something more important...
