Title: (DE) ADAPTIVES ABTASTEN VON BERÜHRUNGSEMPFINDLICHER BILDSCHIRMEINGABE
(EN) ADAPTIVE SAMPLING OF TOUCH SCREEN INPUT
(FR) ECHANTILLONNAGE ADAPTATIF D'UNE ENTREE PAR ECRAN TACTILE
Abstract: front page image
(EN) A touch screen input device (10) includes a display screen (12) adapted for receiving a touch input from a user; means (14) for sampling the touch screen input at any one of a plurality of sampling rates; means (18) for storing a predetermined sampling rate (28) for each application or for each function; and means (16) for setting the sampling rate of the sampling means (14) to the sampling rate (28) stored for a given application or a given function whenever that given application is being executed or that given function is being performed, respectively. In an alternative embodiment, the rate of change (R) of the touch screen input sample points is measured and the sampling rate (f) increased or decreased when the rate of change (R) of the sample points increases or decreases, respectively.
(FR) L'invention se rapporte à un dispositif à entrée par écran tactile (10) comportant un écran de visualisation (12) conçu pour recevoir une entrée tactile d'un utilisateur; un élément (14) destiné à échantillonner l'entrée par écran tactile à une fréquence d'échantillonnage quelconque choisie parmi une pluralité de fréquences d'échantillonnage; un élément (18) destiné à mémoriser une fréquence d'échantillonnage prédéterminée (28) pour chaque application ou pour chaque fonction; et un élément (16) permettant de caler la fréquence d'échantillonnage de l'élément d'échantillonnage (14) sur la fréquence d'échantillonnage (28) mémorisée concernant une application donnée ou une fonction donnée et ce, à n'importe quel moment de l'exécution de cette application donnée ou à n'importe quel moment de l'accomplissement de cette fonction donnée. Selon un autre mode de réalisation, on mesure le taux de variation (R) des points échantillon de l'entrée par écran tactile, la fréquence d'échantillonnage (f) augmentant ou diminuant, respectivement, lorsque le taux de variation (R) des points échantillon augmente ou diminue.
