Abstract:
(EN) Provided in one embodiment of the present invention is a contact position and depth measurement algorithm for a three-dimensional touch recognition device, the algorithm allowing a user input for an elastic and smooth material to be performed such that various user inputs are recognized, determined, and processed, and enabling various patterns to be implemented by recognizing the pattern generated on the basis of three-dimensional coordinates of a point at which contact is made. The contact position and depth measurement algorithm for a three-dimensional touch recognition device, according to the one embodiment of the present invention, comprises the steps of: i) allowing a user input to take effect on a sheet; ii) allowing an imaging unit to transmit, to an analysis unit, a marker image captured by photographing the inner side surface of the sheet per unit time; iii) allowing the analysis unit to measure image variation and position variation of each marker; iv) allowing the analysis unit to analyze the image variation and the position variation of the markers so as to estimate a contact position, which is the position at which a user input is applied, and a contact depth, which is the depth at which the user input is applied; v) allowing the analysis unit to remeasure the image variation and the position variation of a reference marker, which is the closest marker to the contact position, and to remeasure, on the basis of the reference marker, an auxiliary marker positioned within a reference range, which is a predetermined range; and vi) allowing the analysis unit to calculate the contact position and the contact depth by using information of the reference marker and the auxiliary marker.
(FR) Selon un mode de réalisation, la présente invention concerne un algorithme de mesure de position et de profondeur de contact pour un dispositif de reconnaissance tactile tridimensionnel, l'algorithme permettant à une entrée d'utilisateur pour un matériau élastique et lisse d'être effectuée de telle sorte que diverses entrées d'utilisateur sont reconnues, déterminées et traitées, et permettant de mettre en œuvre divers motifs en reconnaissant le motif généré sur la base de coordonnées tridimensionnelles d'un point auquel le contact est réalisé. L'algorithme de mesure de position et de profondeur de contact pour un dispositif de reconnaissance tactile tridimensionnel, selon le mode de réalisation de la présente invention, comprend les étapes consistant à : i) permettre à une entrée d'utilisateur de prendre un effet sur une feuille; ii) permettre à une unité d'imagerie de transmettre, à une unité d'analyse, une image de marqueur capturée par photographie de la surface latérale interne de la feuille par unité de temps; iii) permettre à l'unité d'analyse de mesurer une variation d'image et une variation de position de chaque marqueur; iv) permettre à l'unité d'analyse d'analyser la variation d'image et la variation de position des marqueurs de façon à estimer une position de contact, qui est la position à laquelle une entrée d'utilisateur est appliquée, et une profondeur de contact, qui est la profondeur à laquelle l'entrée d'utilisateur est appliquée; v) permettre à l'unité d'analyse de remesurer la variation d'image et la variation de position d'un marqueur de référence, qui est le marqueur le plus proche à la position de contact, et de remesurer, sur la base du marqueur de référence, un marqueur auxiliaire situé dans une plage de référence, qui est une plage prédéterminée; et vi) permettre à l'unité d'analyse de calculer la position de contact et la profondeur de contact en utilisant des informations du marqueur de référence et du marqueur auxiliaire.
