Instead, we see through a series of visual queries http://www.flickr.com/photos/victoriapeckham/

Generalities >>> SpecificsPROBLEM SOLVING: Brain generates a series of steps to solve a visual problem (VISUAL QUERIES) and executes themEYE MOVEMENTS: Visual searching stage > Scanning the scene for candidates. When it finds something it passes it to the PATTERN TESTING LOOP which validates it.
Patterns become objects as they’re needed.Visual Working Memory = ~3 objects at a time
(REMOVE ALL COLOUR BUT RED)Colour search is much more efficient the fewer colours there are….http://www.flickr.com/photos/wwworks/2473052504/

Visual Queries can be primed / tunedStay consistent. Use the same highlight techniques across charts/graphics. If people know what element they’re seeking then they can find it faster. Colour receptors (or other receptors) will adjust to be more sensitive to the item being soughtPatterns are learned over time(Letters > Words, Charts, Signs, Etc.)Over time, higher level patterns are combinedMuch faster to process (2/10ths of a second)HAVE to be learned though…Much faster to process (2/10ths of a second)HAVE to be learned though…Proxies- Some of these learned patterns can be used as “proxies”… basically shortcuts to a bigger conceptsThetruthabout http://www.flickr.com/photos/thetruthabout/2666835568/Wootang01 http://www.flickr.com/photos/mckln/2894346353/Dno1967 http://www.flickr.com/photos/dno1967/3244178416/Sylvar http://www.flickr.com/photos/sylvar/3360734315/
Our eyes process colour from three perspectives > Red<>Green | Blue <> Yellow | Black <> WhiteThe extremes of each of these contrasts are the most unique/effectivecolours
Avoid visual conjunctionsOur low-level search can only be tuned for one element at a time. Not Both (Pg. 30 in Ware)Find Value a) then find b) among the a candidatesAt the lowest level we can search for only one criteria. We can search for the colour blue OR a square shape.
Channels can be layeredStill Takes additional cycles to process… but more efficient than multiple charts etc
