Abstract

Selon un mode de réalisation, un dispositif électronique peut comprendre : un dispositif de prise de vues ; un écran souple ; et un processeur. La surface arrière de l'écran souple qui fait face à l'appareil de prise de vues peut comprendre un motif disposé le long de la limite entre une première zone et une seconde zone d'une zone active de l'écran souple. Le processeur du dispositif électronique peut acquérir une image par l'intermédiaire de l'appareil de prise de vues en réponse à une entrée visant à activer l'appareil de prise de vues. Le processeur peut identifier si un objet visuel correspondant au motif est inclus dans l'image. Le processeur peut commander un actionneur afin d'aligner l'appareil de prise de vues par rapport à la première zone sur la base de l'image comprenant l'objet visuel.
