CA 2739891

An implementation of a system, device and method for projecting a visual indicator against a surface is provided. A display projection system in a handheld sensor device (e.g. a handheld wall scanner) projects a static or computer-controlled dynamic pattern of light onto a surface being scanned to indicate a specific feature, such as existence of solid structures of wood, metal or plastic, electric or magnetic fields, or a disturbance of a field. The projected light may be controlled by a computer via an aperture to allow flexibility in what is projected, such as icons, lines, graphics, characters and colors.

L'invention porte sur un système, un dispositif et un procédé pour projeter un indicateur visuel contre une surface. Un système de projection daffichage dans un dispositif de détecteur portatif (par exemple, un scanner mural portatif) projette un motif de lumière dynamique statique ou commandé par ordinateur sur une surface scannée pour indiquer une caractéristique spécifique, telle que lexistence de structures solides de bois, métal ou plastique, de champs électrique ou magnétique ou dune perturbation de champ. La lumière projetée peut être commandée par un ordinateur par lintermédiaire dune ouverture pour permettre une certaine flexibilité dans ce qui est projeté, tel que des icônes, des lignes, des graphiques, des caractères et des couleurs.
