Title
(EN) METHOD OF CONSTRUCTING HYBRID TACTILE DISPLAY
(FR) PROCÉDÉ DE CONSTRUCTION D'UN AFFICHAGE TACTILE HYBRIDE
Abstract
(EN)
The present disclosure discloses a method of constructing tactile display with combination of different kinds of stimuli wherein the stimulus of the combination of two or more stimuli that are linearly aligned with each other is perceived at levels lower than the perception threshold values of individual kind of stimulus due to reduction in tactile threshold. The reduction in applied stimulus due to reduction in threshold prevents, discomfort, irritation, burns or any kind of damage in prolonged usage.
(FR)
La présente invention concerne un procédé de construction d'un affichage tactile au moyen d'une combinaison de différents types de stimuli, le stimulus de la combinaison d'au moins deux stimuli qui sont alignés linéairement l'un avec l'autre étant perçu à des niveaux inférieurs aux valeurs de seuil de perception d'un type individuel de stimulus dû à une réduction du seuil tactile. La réduction du stimulus appliqué due à une réduction de seuil empêche une gêne, une irritation, des brûlures ou tout type de dommage pouvait avoir lieu pendant une utilisation prolongée.
