Table 10.2.
Search for a boarding gate on a static screen, series 2
We remark that the times have a tendency to be longer when the number of
people simultaneously present increases, without this tendency being very clear cut.
We also note that the search times among 20 pieces of information are a lot longer
than searches among 12 pieces of information.
10.8.1.3.
Dynamic version
Here we only display information relative to the users situated in proximity to
the screen, see Figure 10.12. Let us note that it could happen that two users are
searching for the same information (they are meant to take the same flight). In this
case, in dynamic mode, the screen was even less loaded than in the previous
experiment. The results are given by Table 10.3.
