ABSTRACT: The importance of the aircraft
is increasing gradually; among them it may be called Ground Control Station
(GCS) receiving the highest expectations. In aspect of operation, operator’s
workload and working speed are one of the most important factors. Thus, we need
to compare Touch mode and Non Touch mode in order to improve workload and
working speed. In this paper, we analyzed the differences of Touch mode and Non
Touch mode about workload, working speed in operation of aircraft. Through
NASA-TLX and Measured working time, quantified data were collected and an
analysis of variance (ANOVA) was performed. According to experimental result,
working speed and workload according to input mode showed significant
difference. In ground operation, Touch mode is better than Non Touch mode about
working speed and workload. In the Touch mode, the optimal value of lower
display angle was selected as 60。 angle.
