# Summary
Interaction design is a science that involves understanding human intent and creating fluid experiences. Metaphors, kinetic physics, and responsive gestures play a role in creating great interactions. Spatial consistency, fluid morphing, and fidgetability also contribute to a positive user experience.
# Facts
- Designers struggle to ground interaction design in science.
- Depth on interaction design can be found through extensive research and analysis.
- Great revelations in design often come from making and problem-solving.
- Interaction design is an artform that combines form and function.
- Metaphors are used in interaction design to create intuitive experiences.
- Deliberate design decisions tap into instinctive behaviors.
- Kinetic physics, such as momentum and angle, enhance interactions.
- The timing and triggering of swipe gestures impact the user experience.
- Responsive gestures provide immediate feedback to the user.
- Spatial consistency and fluid morphing contribute to seamless interactions.
- Frequency and novelty should be considered when animating interactions.
- Fidgetability is a design element that can enhance user engagement.
- Scroll landmarks and touch content visibility aid touch interfaces.
- Implicit input, using context as input, creates a magical user experience.
- Fitts's Law explains how target size and distance impact interaction time.
- Radial menus and operating system corner interactions follow Fitts's Law.
- Scrolling interactions should be optimized for smooth and easy use.
- 💻 Most operating systems allow scrolling in scrollable regions, even if the window is not active
- 👍 With the Magic Mouse, scroll events do not register on a second window when scrolling on the first window
- 👎 Traditional mice like the Logitech MX Master 3 hijack scrolling from the first window when moving to a second window
- 🖱️ With the Magic Mouse, scrolling is explicitly canceled by focusing another window
- 🖐️ Magic Trackpad and Magic Mouse enable direct manipulation for desktop computing
- 🤔 Understanding and analyzing design details helps to nurture taste and appreciate excellence in design execution.
