===Definition===
Ease is the quality of requiring little effort — in interaction design, the property of a system that lets a person accomplish what they came to do without expending attention, learning or patience on the system itself.

It is the direct inverse of the [[Frictional Interface|frictional interface]], and the two are best understood as a single scale.

===Kinds of Ease===
The word covers several distinct properties that trade against one another, and much bad design comes from optimising one and calling it ease.

* '''Ease of learning.''' How quickly a new user becomes competent. Optimised by convention, visible options and forgiving defaults.
* '''Ease of use.''' How little effort a competent user spends. Optimised by shortcuts, memory, and removing steps — often by exactly the means that make learning harder.
* '''Ease of recovery.''' How cheaply a mistake can be undone. The most neglected of the three, and the one that most determines whether people explore a system or approach it warily.
* '''Cognitive ease.''' Daniel Kahneman's term for the subjective sense of fluency, which is produced by familiarity, legibility and repetition — and which people reliably mistake for truth, safety and quality. This is why ease is not automatically a virtue.

The learning/use trade-off is the central design decision and is usually made by default rather than deliberately. A chording keyboard (see [[Mobile Text Entry|mobile text entry]]) chooses expert speed over discoverability; almost every mass-market interface chooses the reverse, and thereby denies its most frequent users any path to expertise.

===Ease and Its Costs===
Ease is not free, and the question is always who pays.

'''Complexity is conserved, not removed.''' Larry Tesler's law of conservation of complexity holds that every process has an irreducible amount of complexity, and the only question is whether the user or the developer absorbs it. An interface that feels effortless has generally moved the work rather than eliminated it — sometimes to the engineer, sometimes to a support worker, sometimes to a person in another country doing the classification the system appears to be doing itself.

'''Ease removes friction in both directions.''' One-click purchase, frictionless sharing and infinite scroll are all genuine reductions in effort, and all reduce the interval in which a person might have reconsidered. Where the interests of the operator and the user diverge, ease is applied asymmetrically — see the discussion of dark patterns under [[Frictional Interface|frictional interface]].

'''Ease can conceal.''' A system that hides its mechanism is easier to use and harder to understand, to audit, to repair and to leave. [[Materials|Repairability]] and legibility are frequently traded away for smoothness.

===When Difficulty Is Right===
Deliberate difficulty is appropriate where the cost of an error is high and irreversible, where a pause serves the person rather than the operator, and where the effort is the point — as in learning, where "desirable difficulties" reliably improve retention. The test is not whether an action is hard but whose interest the hardness serves.

===Relevance to Cyborg Anthropology===
Ease is the quality that makes a technology disappear into ordinary life, and disappearance is the precondition for a tool becoming part of a person rather than something they operate. It is therefore both the goal of good design and the mechanism by which systems become invisible enough to stop being questioned.
