gestalt principles

  • Gestalt psychology is a theory of mind and brain that proposes that the operational principle of the brain is holistic, parallel, and analog, with self-organizing tendencies (via)
  • was originally a theory to describe thought processes, perception
  • basic Gestalt principles:
    • law of closure - we percieve incomplete figures as a whole; our mind fills in the missing information
    • law of similarity - we percieve unity when things appear the same (form, color, size, brightness)
    • when several things are similar we can use contrast (make something dissimilar) to draw attention
    • law of proximity - elements that are close to each other are seen as belonging together
    • law of symmetry - symmetrical objects are seen as belonging together regardless of their distance
    • law of continuity - we percieve a pattern even after it stops
    • figure-ground - the tendency to perceive one aspect of an object as figure or foreground and the other as the ground or background
  • images borrowed from Spokane Falls Communtiy College
  • more on Gestalt principles
  • from a design perspective should be thought of as tools, rather than rules
  • web page elements and objects can be arranged and designed to exploit perception to create understanding

web typography tips

  • the number of typefaces available to web designers is limited due to the way that fonts are specified on web pages
  • creating text as images can overcome this but be careful not to overdo it
  • sans-serif fonts are preferable for body copy
  • serif fonts work but don't make them too small
  • choose fonts that are appropriate for your purpose and audience
  • fonts can also convey implied meaning:
    • sans-serif = modern
    • serif = old-fashioned
    • display = fun, casual
  • fonts can make your site look amateurish (comic sans) or professional (anything other than comic sans)
  • choose a font family and stick with it - too many fonts are like too many colours: can be garish and/or confusing
  • find ways to emphasize headings other than size (CSS)
  • make sure that body copy is legible and resizable
  • try to keep text blocks to a width that accommodates 8-12 words per line - longer lines make it harder to keep position
  • experiment with line spacing using CSS to improve readability
  • use centred text sparingly and never for large passages or entire web sites
  • never justify text - screens deal badly with extra spaces
  • use text as a design element when good imagery is lacking

in-class exercise

To be continued in week five.

Create a home page mockup for Giant Client using the following:

Once you've finished the home page, create a variant for use on second level pages. What will you change? What will stay the same? Why? Be prepared to explain your choices.
