In-Depth Information
Dynamic version.
In this version, the screens display in addition information that
concerns users situated in proximity (see Figure 10.18). The departure times of the
trains of the latter, as well as their platform numbers and arrows that indicate the
directions to follow, complete the basic static display.

Results of the direction search experiment with the help of dynamic screens
As in the previous experiment, users starting from the corridor extremities
(landmarks 0 and 2) were already following optimal trajectories. We did not
reiterate these experiments and we concentrated on the experiments in which
subjects started from the middle of the corridor (landmark 1). The corresponding
results are given in Table 10.5. We can note that in all cases the movements are
optimal. On average, the use of a dynamic system brought the relative length of the
journeys departing from landmark 1 from 2.75 to 1.00.
