Search time for a boarding gate on a dynamic screen
These results led to the following conclusion: the search for a piece of
information is much quicker when only information relative to users in the
immediate proximity is presented; see Figure 10.13.
Figure 10.13.
Comparison of the search times for a flight in terms of the number of people
simultaneously present. For each case studied, a segment figures on the graph: it indicates
the minimum and maximum times. The point situated in the segment represents the average
time. For legibility reasons, results of static experiment No. 1 are slightly staggered to the
left, whereas those of static experiment No. 2 are slightly staggered to the right. The results of
the dynamic experiment are therefore between the results of these two static experiments
