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

Page 30: Persuasive systems design: Case Recover! app · ⑥Persuasion through persuasive systems must always be unobtrusive to a user’s primary tasks ⑦Persuasion through persuasive systems

Humanized

technologies

Being part of our everyday lives

opens up tremendous

opportunities for influencing

people’s behaviors

The role of persuasive systems

design will only keep growing

Finally, effort should be put

into…

Page 31: Persuasive systems design: Case Recover! app · ⑥Persuasion through persuasive systems must always be unobtrusive to a user’s primary tasks ⑦Persuasion through persuasive systems

… understanding user behaviors

better

Page 32: Persuasive systems design: Case Recover! app · ⑥Persuasion through persuasive systems must always be unobtrusive to a user’s primary tasks ⑦Persuasion through persuasive systems

… building HBCSSs for users

Page 33: Persuasive systems design: Case Recover! app · ⑥Persuasion through persuasive systems must always be unobtrusive to a user’s primary tasks ⑦Persuasion through persuasive systems

… by using PSD methodology

Page 34: Persuasive systems design: Case Recover! app · ⑥Persuasion through persuasive systems must always be unobtrusive to a user’s primary tasks ⑦Persuasion through persuasive systems
