Basics Flashcards
What is Animation?
Animation is an umbrella term for the practice of adding motion to imagery. While it’s a part of UX/UI design, it also encompasses other fields - such as film, gaming, and VR.
What is Motion Graphics?
Refers to the process of adding motion to graphic design elements. Motion graphics are a type of animation.
Unlike other types of animation, motion graphics tend to place less emphasis on storytelling.
Why is UI animation important?
Animation adds a vital human touch to digital interfaces by simulating the experience of interacting with a physical object in real life. This helps make digital products human-centered, intuitive, and responsive.
This makes for an easier, more natural experience for the user, and reduces cognitive load.
Animation also reduces stress by providing real-time updates and feedback, keeping the user informed at all times.
From another perspective, animation can make an interface fun and engaging. Having a visually appealing interface is vital, and including just the right amount of animation could set you apart from the crowd.
What is the persistence of vision?
The optical illusion occurs when visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye.
The persistence of vision is an optical illusion where the human eye perceives the continued presence of an image after it has disappeared from view. Also known as retinal persistence, this optical effect was described by English-Swiss physicist Peter Mark Roget in the nineteenth century.
In the motion picture industry, animators have combined the basic principle of persistence of vision with the phi phenomenon, which postulates that showing still images in rapid succession can create the illusion of movement—as in a flipbook, for example. To this day, filmmakers rely on these phenomena to create the illusion of motion in animated films.
How does animation work?
Animation works by using an optical illusion.
By presenting a sequence of still images in quick enough succession, the viewer interprets them as a continuous moving image.
What is a frame rate?
Frame rate, which is also commonly labeled as frames per second (fps), is a term used to describe how many still frames will compose a single second of a moving image.
