While the first three levels of the hierarchy focus on enabling users to use a system, this final tier focuses on encouraging them to do so.
Persuasive technologies compel users to act in a required way. The disciplines of psychology and HCI have built much knowledge as to how people react to various stimuli, and this knowledge can be harnessed when developing interactive technologies.
The purposes of compelling different behaviours may be:
- Increased use of the product itself.
- Increased use of certain functions such as premium services.
- Changing behaviours elsewhere to make users more sociable, healthy, productive, etc.
The psychological principles underlying emotion and persuasion have been studied for up to 100 years. More recently, practitioners (notably at Stanford University) have started to apply these learnings to the specific realm of technologies and interactive systems. New principles have been developed, and ethical conduct criteria have been established to ensure that these powerful techniques are not used to public detriment.
Methods that focus on persuasion include:
- Task analysis
- Iterative prototyping
- Expert review
- Real-user testing
- Collaborative design
Persuasion completes the hierarchy of system requirements. A persuasive system guarantees that the product will be used.
