Abstract:
(EN) A method and apparatus for distinguishing writing made by multiple electromagnetic pens, and an electronic device. The method comprises: calculating touch position information and pressure sensing information about an electromagnetic pen by acquiring an electromagnetic touch signal produced when writing is carried out with the electromagnetic pen; expanding the pressure sensing information, so that the pressure sensing information generated by different electromagnetic pens has different characteristics; encapsulating the touch position information and the expanded pressure sensing information into a multi-point touch signal; matching writing attribute information pre-set for the electromagnetic pen according to the expanded pressure sensing information; and generating a writing trajectory having the pre-set writing attribute at a touch position of the electromagnetic pen. By setting writing attribute information, such as different colours and line shapes, when writing is carried out with different electromagnetic pens, a writing trajectory of different colours and line shapes can be generated, so as to distinguish between writing content corresponding to each writer.
(FR) La présente invention concerne un procédé et un appareil pour distinguer une écriture produite par de multiples stylos électroniques, et un dispositif électronique. Le procédé consiste à : calculer des informations de position de contact et des informations de détection de pression relatives à un stylo électromagnétique, par l'acquisition d'un signal de contact électromagnétique produit pendant l'écriture avec le stylo électromagnétique ; étendre les informations de détection de pression, de sorte que les informations de détection de pression générées par différents stylos électromagnétiques présentent des caractéristiques différentes ; encapsuler les informations de position de contact et les informations de détection de pression étendues dans un signal de contact multipoint ; mettre en correspondance des informations d'attribut d'écriture prédéfinies pour le stylo électromagnétique selon les informations de détection de pression étendues ; et générer une trajectoire d'écriture présentant l'attribut d'écriture prédéfini au niveau d'une position de contact du stylo électromagnétique. La définition des informations d'attribut d'écriture, telles que des couleurs différentes et des formes de ligne différentes pendant l'écriture avec différents stylos électromagnétiques, permet de générer une trajectoire d'écriture présentant des couleurs et des formes de ligne différentes qui permettent de distinguer le contenu d'écriture correspondant à chaque personne qui écrit.
(ZH) 一种多电磁笔书写区分方法、装置及电子设备,所述方法通过获取电磁笔书写时产生的电磁触摸信号计算电磁笔的触摸位置信息、压感信息;对压感信息进行扩充,使不同的电磁笔生成的压感信息具有不同特征;将触摸位置信息、扩充后的压感信息封装成多点触摸信号,根据扩充后的压感信息匹配为电磁笔预设的书写属性信息,在电磁笔的触摸位置生成具有预设书写属性的书写轨迹。通过设置不同的颜色、线形等书写属性信息,使用不同的电磁笔书写时,能够生成不同颜色、线形的书写轨迹,从而区分出各书写者对应的书写内容。
