  • Grid systemsGrid systems help designers organise information ito a coherent pattern.

    Gutters are the blank spaces that separate rows and columns

  • What applications do you find this grid system?

  • Powerpoint

  • Another familiar grid?See Comments in notes

  • Internet explorer gridSketch the grid IE uses

  • Your screen productSketch here the type of grid that would be most useful for the product you are building

  • Visual FlowIn Western culture the visual flow is left to right, top to bottom.Dont force users eyes to jump all over the screen.Achieve visual flow by the use of whitespace, positioning and alignment of objects

  • Squint testSquinting at the screen enables you to smudge the details and see which items on the screen have prominence.

    Good idea to use this on any visual interface you are designing

    Results may be surprising as it reveals that secondary of unimportant items seem overly important in the design

  • TypographyAn important choice in any visual interfaceProvides a platform for usable readable and clear labels and text & also personality

  • TypefacesCommonly called fontsGenerally categorised into two groups: serif and sans serifArialVerdanaTrebuchetTahomaTimes New RomanGeorgiaBookman Old Style

    Sans - serifSerif

  • TypefacesSerif typefaces are easy to read, excellent for long passages of text (eg books)

    San serif typefaces traditionally used for shorter passages of text eg signage

    Default choice for interaction designers in screen or physical design used for button labels instructional text, menus etc

    Medium width typefaces are good to use

    Avoid any that appear very heavy or very light

    Avoid using lots of different typefaces at one or combining type faces that are too similar

  • Generally typographic guidelinesAvoid using too many different type sizes and widths at the same time.All CAPITALS severely detracts from readabilityAvoid stretching or distorting typefaces

  • Typographic guidelinesSize: for screens 9 12points; mobile screen 6- 10 points; on physical devices- depends on size of device 6-9 points common

    Alignment: flush left and ragged right is more legible than flush right or justified. Use flush right sparingly; and justified for long line lengths.

    Rivers: formed when the white spaces between words seemingly lin up and form a river Avoid these.

    Widows & orphans: avoid widows (a word left on a line by itself) and orphans (a single word at the beginning of a column or page).

    Line Length: Goldilocks principle: not too long; not too short; but just right! Minimum characters 40; strive for 55- 75

    Leading: vertical space between lines. should 20% more than the font size (eg 10 point font, 12 point leading); very small fonts (ie below 8 points) needs more space; longer the lines more space is required; never add more than 40%

    Kerning: horizontal space between letters. Usually only needed in font sizes larger than 18 point.

  • ColourIn visual interface design, colour can be used to create personality and tone and provide cues for useEg red buttons on a mobile phone stop.Colour can establish relationships between disparate objects; Indicate importance

  • ColourColour can be greatly misused:Dull Too many coloursToo many saturated colours10% of male population has colour blindness (red/green) For more on colour see http://learnline.cdu.edu.au/units/hit151/basics/ colour.html

  • Material and ShapeThe physical form of a device tells a lot about how and where the device is meant to be used.Physical form can be made of: metal, plastic, wood clay, ceramic, cloth, rubber, glass, leather or a combination Ergonomics and human factors come into play- eg how small can a button be before a person cant press itOverall shape and size of a device are important visually. Think about the tablet PC as an example.

    This grid is often used in email clients and RSS readersWhat does yours use?
