4. Ergorama-panorama links

By studying the ergorama and then the panorama, we were able to organize the luminance field in such a way as to enable appropriate visual performance while ensuring good visual hygiene conditions. This would perhaps be sufficient if the situation were static. But this is not the case. Depending on the type of activity, situations change both in terms of time and space. It is therefore necessary to examine the extent to which the organization of the visual space will enable the activity to be carried out without physical or mental overload, while maintaining a sufficient level of vigilance.

To this end, and following the proposals of E. Barthès and J.L. Richard, we distinguish three successive phases in the activity:
