Peripheral vision in a human-machine interface

A computer-implemented method for managing a graphical human-machine interface, includes the steps of receiving information relating to the position of the eyes and the gaze direction of a user at the interface; receiving physiological information of the user; determining a level of cognitive load on the basis of the received physiological information; adjusting the display of the interface on the basis of the gaze direction and/or of the determined level of cognitive load. Some developments describe the management of the display zones (foveal zone and peripheral zones), the selection of one or more displays, the management of the distance from the message display to the current gaze location, the management of the criticality of the messages, various graphical techniques for attracting attention, the management of the flight context in the avionic case, the management of visual density, etc. Some system aspects are described (virtual and/or augmented reality).
