The animated GUI
Lessons from Disney
Kristel Van Ael and Joannes Vandermeulen of Namahn at SIGCHI.be Fall Conference on New Communities 19/10/2009
What are the principles of animation?How can animation enhance the user experience?
Assignment from Atos Worldline: use the full potential of a new 16-bit colour display to create a user-friendly and appealing interface for a new XENTA point-of-sales terminal.
Basic interface concept and flows designed by Namahn in 2003, and still standing
Now focus on colour, typography, iconography and … animation
Context
Provide a natural flow
Focus attention on the action
Provide a sense of bearing
Engage and appeal
NOT: disrupt or hold back
Why animate?
The illusion of motion
The human eye perceives motion at about 24 fps (frames per second)
20 fps is enough for simple feedback
25 fps is accepted as very decent
+30 fps for games
Frame rate
In the real world, an object leaves an impression of its path in our visual system – a smear.
Motion blur
A rule of thumb: if an object moves more than half its size between any two frames, motion blur must be added.
Motion blur
Visual response to user actions needs to be without delay
0,1 second is about the limit for having the user feel that the system is reacting instantaneously
More complex action may take at most 1,5 seconds
Instant response
8 Design principlesSolid drawing
Squash and stretch
Arrival and departure
Ease-in, ease-out
Arcs
Follow-through
Anticipation
Exaggeration
“Does your animation have weight, depth and balance?”
Solid drawing
Solid drawing
The creation of objects so they appear to have the potential for movement
Solid drawing
Avoid static symmetry and twin movements
Squash and stretch
Squash and stretch

Squash and stretch
Pin dropping in Google Maps on iPhone
Arrival and departure
Arrival and departure
In real live, objects do not appear (enter) or disappear (exit) suddenly
Three variations: objects fly in from off-screen,
objects grow from a point to their full size
objects dissolve onto the screen.
Objects exit in the opposite way that they entered
Arrival and departure
Visibility curve
Ease-in, ease-out
Ease-in, ease-out
Ease-in is a gradual acceleration into a motion from a key position
Ease-out is the gradual deceleration out of the motion to a key position
In either case this principle refers to the simple fact that objects in the real world do not suddenly start or stop moving

Arcs
The movement of most natural motion will be described by a slightly circular path or arc of some kind.
Follow-through
Follow-through
Objects in the real world do not come to sudden stops, all of the object coming to a standstill at once
Example: objects coming to a stop will wiggle at the end of their motion, as if reacting to a small spring at the end of their travel
Combine with overlapping motion
Anticipation
Anticipation
Anticipation is a technique to alert the viewer to an upcoming action so it is not missed. Exaggerating in order to give the audience a cue about the main action to follow
Examples: Contrary movement just before move
Retracting slightly before expanding
A character looking off screen in the direction where an important action is about to happen
Anticipation
Exaggeration
Exaggeration
By increasing the salience of certain aspects of the world, the animator gives the audience footholds from which to better interpret the nature of the character, action, or situation
Paradoxically, only by exaggeration do cartoons achieve more realism.
