Designing Interfaces: Patterns for Effective Interaction Design

•when a person uses an application, he interacts with the machine

•the machine must be as close to responsiveness as human: it should indicate when it's active (listening) and when it responds

•when designer designs a system, he designs a personality, the way the system responds

•user experience is not only about buttons and pages, it applies to modern technologies as well: user experience in virtual reality, touch screens, voice assistants

•it's useful to think of designing as a process of building up layers of design, one on top of the other (1-logical layer: concepts, relationships, categories; 2-functional layer: pages, lists, cards; 3-presentation layer: colors, layouts, graphics)

•best practices of UX: disassembling big tasks into steps for users to communicate their progress; highlighting the most frequently used apps

•When combining fonts that are in the same typeface family, use a different weight or style (bold, italic) to differentiate the text

•it's absolutely necessary to design interface for mobile devices. When designing it, try to minimize typing (it's better to provide users with an auto completion feature), design different screen colors, light and dark, place buttons down there, so that they were easily reachable

•usually mobile users go to mobile apps to check a specific information right now (weather right now, news right now etc)

•it's not always smart to make all the functionality visible. Sometimes it's better to use hover function and show the buttons to the user only when he wants to do an action (like it is in Slack or YouTube)
