Principles of Interaction Design
According to
Nielsen
Norman Group, there are several important fundamental
principles of interaction design that are completely independent of
technology:
· Visibility (also called perceived
affordances or signifiers)
· Feedback
· Consistency (also known as
standards)
· Non-destructive operations (hence
the importance of undo)
· Discoverability: All operations
can be discovered by systematic exploration of menus
· Scalability. The operation should
work on all screen sizes, small and large.
· Reliability. Operations should
work. Period. And events should not happen randomly.
The first principle visibility need to be extended to hearing with same fundamental awareness.
Distictive Non-intrusive Non-speech Audio Design
Non-speech audio is part of everybody's daily life. It contains rich
information. You may not notice it but it's vital for evironment
awareness. The design would definitely take this virtue. The difficulty
is distictive but non-intrusive sound design. It requires unique
non-nature sound to isolate itself from environment. It also requires
non-intrusive except alert sound to comfort user as background
information. How hard it is!
Instant Interactive Audio Feedback Design
Instant interactive audio feedback design is the key element. Just like
scratching sound on the surface of an objetc, user can percieve the
attribute of the object. The sound is generated by user interaction
with the object in the fashion of instant feedback. User may adjust the
action in "no time". It's the closed loop of interaction. Machine
provides this means only without involve into interpreting the user
action, make decision and then send feedback. However, machine can
retrieve the user action from the closed loop. This is the design
guidline.
