Sources of mode confusion
Mode confusion is due to
design mistakes:
Mode confusion occurs in two situations:
- Implicit state: the
state is not formalized in the
system design.
The design assumes that it is implied from the sequence of
operation (mode
confusion).
example: home TV
- Explicit state: the
state is formalized in the
system design, but
the operators are not aware of or disregard the
mode
(mode error)..
Example: Torrey Canyon
