Abstract

The present invention relates to a display system for stereoscopic viewing, the system comprising a binocular viewing device, information content, and a display source. The display system is remarkable in that it further comprises electronic components for implementing pieces of software for optimizing the binocular viewing device, the information content, and the display source, said pieces of optimization software together forming a loop for managing various parameters. The wearer of said device can thus view the information content via the binocular viewing device under conditions that are best adapted to the wearer'"'"'s physiology.
