Abstract
(EN)
In one embodiment, an electronic assembly includes a flexible circuit board formed into a curved shape that is configured to be substantially concentric with a viewer's eye. The electronic assembly further includes a plurality of facets coupled to a side of curved shape of the flexible circuit board that is configured to face the viewer's eye. Each facet has a planar face, one or more emitters configured to emit light towards the viewer's eye, and one or more receptors configured to detect the emitted light after it has been reflected back towards the electronic assembly from a retina of the viewer's eye. Each face is normal to a line pointing towards a center area of the viewer's eye when the curved shape is substantially concentric with the viewer's eye. Each facet is individually addressable such that the plurality of facets are configurable to detect a center of gaze of the viewer.

Dans un mode de réalisation, ‌la‌ présente invention ‌concerne‌ un ensemble électronique qui comprend une carte de circuit imprimé souple formée en une forme incurvée qui est configurée pour être sensiblement concentrique avec l’œil d'un observateur. L'ensemble électronique comprend en outre une pluralité de facettes couplées à un côté de forme incurvée de la carte de circuit imprimé souple qui est configurée pour faire face à l’œil du spectateur. Chaque facette a une face plane, un ou plusieurs émetteurs configurés pour émettre de la lumière vers l’œil du spectateur, et un ou plusieurs récepteurs configurés pour détecter la lumière émise après que celle-ci a été réfléchie vers l'ensemble électronique à partir d'une rétine de l’œil du spectateur. Chaque face est perpendiculaire à une ligne pointant vers une zone centrale de l’œil du spectateur lorsque la forme incurvée est sensiblement concentrique avec l’œil du spectateur. Chaque facette est adressable individuellement de telle sorte que la pluralité de facettes sont configurables pour détecter un centre de regard du spectateur.
