A dynamic projected user interface includes a light source for generating a light beam and a spatial light modulator for receiving and dynamically modulating the light beam to create a plurality of display images that are respectively projected onto a plurality of keys in a keyboard. An optical arrangement is disposed in an optical path between the light source and the spatial light modulator for conveying the light beam from the light source to the spatial light modulator.

L'invention porte sur une interface utilisateur projetée dynamique, qui comprend une source de lumière pour générer un faisceau lumineux et un modulateur de lumière spatial pour recevoir et moduler de façon dynamique le faisceau lumineux pour créer une pluralité d'images d'affichage qui sont respectivement projetées sur une pluralité de touches dans un clavier. Un agencement optique est disposé dans un trajet optique entre la source de lumière et le modulateur de lumière spatial pour transporter le faisceau lumineux de la source de lumière au modulateur de lumière spatial.
