Abstract

Est décrit un dispositif électronique comprenant un afficheur, un processeur, une mémoire, et une interface d'entrée de stylet configurée pour recevoir une entrée de stylet provenant d'un stylet numérique. Le dispositif électronique peut afficher une première image sur l'afficheur et recevoir une première entrée tactile sur l'afficheur. Le dispositif électronique peut définir au moins une zone partielle de l'afficheur en tant que zone de prévisualisation tandis que la première entrée tactile est maintenue, définir une propriété concernant une entrée du stylet numérique en tant que première propriété, recevoir une première entrée concernant la zone de prévisualisation provenant du stylet numérique, et afficher une première image de prévisualisation qui est basée sur la première entrée, en superposant la première image de prévisualisation sur la première image. Lorsque la première entrée tactile est relâchée, le dispositif électronique peut arrêter l'affichage de la première image de prévisualisation et maintenir la propriété concernant l'entrée du stylet numérique en tant que ladite première propriété. Divers autres modes de réalisation identifiés tout au long du présent document sont possibles.
