Abstract

L'invention concerne un dispositif portatif d'interaction avec un cristal, ainsi qu'un système et un procédé d'interaction. Le dispositif portatif d'interaction avec le cristal comporte: un moyen de commande, et une balle de détection de pression qui est reliée au moyen de commande, une cavité intérieure de la balle de détection de pression comportant une cavité pneumatique et une cavité de mise en place qui sont agencées de manière cloisonnée; la cavité pneumatique est une cavité élastique qui se déforme sous un effort pour faire varier la pression dans la cavité; un système mécanique microélectronique et un unité de traitement de données sont agencés dans la cavité de mise en place; un capteur de pression d'air servant à détecter une variation de pression d'air est agencé dans la cavité pneumatique; et un commutateur de commande de verrouillage, qui est en liaison de communication avec le moyen de commande et verrouille une position correspondante dans un cristal au moyen d'un mappage, est en outre agencé sur le corps de la balle de détection de pression. Au moyen du dispositif portatif d'interaction avec le cristal, et du système et du procédé d'interaction avec le cristal, une structure microcristalline dans un espace virtuel est transposée sur une balle tenue à la main au moyen du dispositif portatif d'interaction avec le cristal, de sorte qu'un utilisateur interagit visuellement avec la structure microcristalline d'une manière cohérente avec un événement réel et, en particulier lorsqu'une structure cristalline est soumise à un ajustement complexe, l'utilisateur a la possibilité de se concentrer davantage sur un résultat d'ajustement plutôt que sur un processus d'ajustement.
