Gestalt principles
Definition
- proximity
- similarity
- common fate (similar motion grouped together)
- continuity (continuous closures belong together)
- closure (closed contour ->group together
- common region (inside same region -> group together)
- element connectedness (stronger than similarity, weaker than common region
Term
synchrony
Definition
when objects move synchronously = generalized common fate
Term
signal-to-noise ratio
Definition
- maximize the intended information: signal
- minimize the extraneous information: noise
Term
progressive disclosure
Definition
- separate information to multiple layers
- default: present primary layer that is necessary and relevant
- place signifier to disclose more information
Term
what are the two special cases of the gestalt principle closure?
Definition
