Abstract:
(EN) A keyboard input system and a keyboard input method using finger gesture recognition are disclosed. The keyboard input system according to an embodiment of the present invention comprises: a virtual keyboard display unit that is configured to overlay and display a virtual keyboard having keys arranged thereon onto an image obtained by an image capturing unit; and a virtual keyboard input unit that is configured to output the keys of the virtual keyboard based on the finger gestures of a user that are recognised from the image. The virtual keyboard input unit comprises: a finger recognition unit that is configured to recognise a finger gesture of the user from the image; a click gesture determination unit that is configured to determine whether the finger gesture is associated with a predetermined click gesture; and a key output unit that is configured to determine a key that is overlapped with a predetermined finger position of the user when the click gesture occurs. The click gesture may include an interaction between two or more fingers of the user.
(FR) L'invention concerne un système de saisie au clavier et un procédé de saisie au clavier utilisant une reconnaissance de geste de doigt. Le système de saisie au clavier selon un mode de réalisation de la présente invention comprend : une unité d'affichage de clavier virtuel qui est configurée pour recouvrir et afficher un clavier virtuel ayant des touches disposées sur celle-ci sur une image obtenue par une unité de capture d'image; et une unité de saisie au clavier virtuel qui est configurée pour afficher les touches du clavier virtuel sur la base des gestes de doigt d'un utilisateur qui sont reconnus à partir de l'image. L'unité de saisie au clavier virtuel comprend : une unité de reconnaissance de doigt qui est configurée pour reconnaître un geste de doigt de l'utilisateur à partir de l'image; une unité de détermination de geste de clic qui est configurée pour déterminer si le geste de doigt est associé à un geste de clic prédéterminé; et une unité d'affichage de touche qui est configurée pour déterminer une touche qui est chevauchée par une position de doigt prédéterminée de l'utilisateur lorsque le geste de clic se produit. Le geste de clic peut comprendre une interaction entre deux doigts ou plus de l'utilisateur.
(KO) 손가락 동작 인식을 이용한 키보드 입력 시스템 및 키보드 입력 방법이 개시된다. 본 발명의 실시예에 따른 키보드 입력 시스템은 영상 촬영부에 의해 획득된 영상에 글쇠들이 배열된 가상 키보드를 겹쳐서 표시하도록 구성되는 가상 키보드 표시부; 및 영상에서 인식된 사용자의 손가락 동작을 기반으로 가상 키보드의 글쇠를 출력하도록 구성되는 가상 키보드 입력부를 포함한다. 가상 키보드 입력부는 영상에서 사용자의 손가락 동작을 인식하도록 구성되는 손가락 인식부; 손가락 동작이 설정된 클릭 제스쳐에 해당하는지 판단하도록 구성되는 클릭 제스쳐 판단부; 및 클릭 제스쳐가 발생한 때에 사용자의 설정된 손가락 위치와 중첩되는 글쇠를 결정하도록 구성되는 글쇠 출력부를 포함하다. 클릭 제스쳐는 사용자의 적어도 두 손가락들 간의 상호 작용을 포함할 수 있다.
