| Summary: | 碩士 === 國立交通大學 === 工業工程研究所 === 83 === The purpose of this study was to investigate the effect of
information display format on the performance of three
malfunction detection task.It aimed to examine which type of
display format is suitable for different kinds of tasks. The
experiment sample consisted of 36 university and gra- duate
students.By using split-plot repeated measure design, subjects
were randomly assigned to four blocks(i.e. alpha numeric
display,bar display,object display,and mimic disp- lay)and all
of them were asked to detect abnormality consis- ted of three
different kind tasks ( i.e. simple rule based task , complex
rule based task , and knowledge based task ).Before the
experiment started,subjects has to learn rules and knowledge of
the system. Then, subjects were instructed to perform the
simulated monitoring task on PC.Subjects were tested for their
performance with every system state,and response time along
with its accuracy was recorded. The result showed that there
was an effect of malfunction detection on dealing with
different information display format .In terms of accuracy,the
alpha numeric display perform worstor complex rule based task;
bar display performs better on ru- le based task than on
knowledge based task;object display and mimic display both
perform best on simple rule-based task;Pu- tting the result in
response time and accuracy together , theimic display is
effective.The result indicated providing sys- tem state
information in the format which is compatible with their task
familiarity display can aid users in performing mal- function
detection task.
