Using animated tutorials or walkthroughs in software interfaces to guide users through complex processes, such as setting up a new account or configuring settings.
P8. Information access
Placing important information, such as contact details or a call-to-action button, prominently at the top of a webpage where it is easily visible upon landing
P9. Proximity compatibility
Grouping related controls or options together in a software toolbar or menu, making it intuitive for users to locate and access functions that are commonly used together.
P10. Multiple resources
implementing keyboard shortcuts in software applications to allow users to perform tasks efficiently using both keyboard and mouse inputs simultaneously.
P11. Knowledge in world
Using real-world metaphors in digital interfaces, such as a desktop folder icon to represent file storage, to leverage users’ existing mental models and facilitate understanding.
P12. Predictions
Anticipating a user’s next actions in an e-commerce website based on their browsing history and providing personalized product recommendations accordingly.
