Humans are limited in their capacity to process information. This has important implications for design. Information is received and responses given via a number of input and output channels: o
visual channel
o
auditory channel
o
haptic channel
o
movement
Information is stored in memory: o
sensory memory
o
short-term (working) memory
o
long-term memory
Information is processed and applied: o
reasoning
o
problem solving
o
skill acuisition
o
error
!motion influences human capabilities. "sers share common capabilities but are individuals with differences# which should not be ignored.
The computer $ computer system comprises various elements# each of which affects the user of the system. •
Input devices for interactive use# allowing te%t entry# drawing and selection from the screen: o
te%t entry: traditional keyboard# phone te%t entry# speech and handwriting
•
•
•
•
o
pointing: principally the mouse# but also touchpad# stylus# and others
o
&' interaction devices
utput display devices for interactive use: o
different types of screen mostly using some for m of bitmap display
o
large displays and situated displays for shared and public use
o
digital paper may be usable in the near future
irtual reality systems and &' & ' visuali*ation have special interaction and display devices. arious devices in the physical world: o
physical controls and dedicated displays
o
sound# smell and haptic feedback
o
sensors for nearly everything including movement# temperature# bio-signs
+aper output and input: the paperless office and the less-paper office: o
o
•
•
different types of printers and their characteristics# character character styles and fonts scanners and optical character recognition
,emory: o
short-term memory: $,
o
long-term memory: magnetic and optical disks
o
capacity limitations related to document and video storage
o
access methods as they limit or help the user
+rocessing: o
the effects when systems run too slow or too fast# the myth of the infinitely fast machine
o
limitations on processing speed
o
networks and their impact on system performance.
The interaction
•
•
•
•
Interaction models help us to understand what is going on in the interaction between user and system. They address the translations between what the user wants and what the system does. !rgonomics looks at the physical characteristics of the interaction and how these influence its effectiveness. The dialog between user and system is influenced by the style of the interface. The interaction takes place within a social and organi*ational conte%t that affects both user and system.
