Title (EN) METHOD AND APPARATUS FOR SENSING MULTI-TOUCH INPUTS
(FR) PROCÉDÉ ET APPAREIL POUR DÉTECTER DES ENTRÉES À EFFLEUREMENTS MULTIPLES
(KO) 복수의 접촉 입력을 감지하는 방법 및 장치
Abstract: front page image
(EN)Provided is a method for sensing multi-touch inputs, and more particularly, to a method for sensing at least two touch inputs, which comprises the steps of: receiving a sensing signal through plural sensor electrodes; obtaining from the received sensing signal a value that depends on the distance between the touch inputs; and determining the existence of two or more touch inputs if the obtained value is larger than a threshold value. The plural sensor electrodes include a pair of sending electrodes that correspond to coordinates on the same first axis, and the sensing signal is received from the pair of sending electrodes along the first axis in the step for receiving the sensing signal.
(FR)La présente invention concerne un procédé de détection d'au moins deux entrées à effleurement, et plus particulièrement un procédé permettant de détecter les entrées à effleurements multiples. Ce procédé consiste d'abord à recevoir un signal de détection au moyen d'une pluralité d'électrodes de détection. Le procédé consiste ensuite à déterminer à partir du signal de détection reçu une valeur fonction de l'écart entre les entrées à effleurement. Le procédé consiste enfin à déterminer l'existence d'au moins deux entrées par effleurement si la valeur obtenue est supérieure à une valeur plafond. Parmi les électrodes de détection de la pluralité d'électrodes de détection se trouve une paire d'électrodes émettrices qui correspondent aux coordonnées selon un premier axe. Pour l'opération de réception du signal de réception, le signal de détection pris en compte provient de la paire d'électrodes émettrices selon le premier axe.
(KO)2 이상의 접촉 입력들을 감지하기 위한 방법에 있어서, 복수의 감지 전극에 의해 감지 신호를 수신하는 단계와, 상기 수신된 감지 신호로부터 상기 접촉 입력들간의 거리에 의존하는 값을 획득하는 단계와, 상기 획득된 값이 문턱값 이상인 경우에 2 이상의 상기 접촉 입력들이 존재하는 것으로 결정하는 단계를 포함하는 접촉 입력 감지 방법이 제공된다. 복수의 감지 전극은 동일한 제 1 축 좌표에 대응되는 감지 전극쌍을 포함하고, 상기 감지 신호를 수신하는 단계는 상기 제 1 축을 따라 상기 감지 전극쌍으로부터 감지 신호를 수신한다.
