Abstract
(EN) Embodiments of the present invention relate to a recognizable electronic paper and an answer card. The electronic paper comprises a substrate. Multiple signal sensing units are disposed on the substrate. Each signal sensing unit comprises at least two end portions, and the multiple signal sensing units are arranged in an array manner. The electronic paper also comprises a signal detection unit. Two end portions of the signal sensing unit are in communication connection with the signal detection units respectively. A user changes the state of a signal sensing unit to record writing information of the user. The signal detection unit inputs an electrical signal to one end of the signal sensing unit, and the signal detection unit senses signal change information of the signal sensing unit according to an electrical signal of the other end of the signal sensing unit. The signal detection unit determines writing information of the user according to the signal change information of the signal sensing unit and position information of the signal sensing unit. In the embodiments of the present invention, writing information of the user is recorded by means of the signal change information of the signal sensing unit, and writing information of the user can be determined according to the signal change information and the position information of the signal sensing unit.
(FR) Des modes de réalisation de la présente invention se rapportent à un papier électronique reconnaissable et à une carte de réponse. Le papier électronique comprend un substrat. De multiples unités de capture de signaux sont disposées sur le substrat. Chaque unité de capture de signaux comprend au moins deux parties d’extrémité, et les multiples unités de capture de signaux sont agencées sous forme de matrice. Le papier électronique comprend également une unité de détection de signaux. Deux parties d’extrémité de l’unité de capture de signaux sont en connexion de communication respectivement avec l’unité de détection de signaux. Un utilisateur change l’état d’une unité de capture de signaux pour enregistrer des informations d’écriture de l’utilisateur. L’unité de détection de signaux entre un signal électrique à une extrémité de l’unité de capture de signal, et l’unité de détection de signaux capture des informations de changement de signal de l’unité de capture de signaux selon un signal électrique de l’autre extrémité de l’unité de capture de signaux. L’unité de détection de signaux détermine des informations d’écriture de l’utilisateur selon les informations de changement de signal de l’unité de capture de signaux et des informations de position de l’unité de capture de signaux. Dans les modes de réalisation de la présente invention, des informations d’écriture de l’utilisateur sont enregistrées au moyen des informations de changement de signal de l’unité de capture de signaux, et des informations d’écriture de l’utilisateur peuvent être déterminées selon les informations de changement de signal et selon les informations de position de l’unité de capture de signaux.
