Non-contact type intelligent inputting method based on video images and device using the same

The invention discloses an interactive intelligent inputting method based on video images. The interactive intelligent method based on the video images is capable of enabling a user to achieve non-contact type operations. Through collecting information like motion paths, speed and acceleration of two hands of the user, the input function of an entity keyboard is achieved, and the collected information is outputted in the mode of characters for upper layer software to invoke and achieve customized application. The non-contact type intelligent inputting method based on the video images is capable of further achieving dynamic adjustment of the operation range of the virtualized keyboard according to the change of the motion range of the two hands of the user. When the two hands of the user are arranged in the working area of an image collection device, a displaying device displays the relative positions of the virtualized keyboard and virtualized fingers of the user, the user can achieve the corresponding operations of the buttons of the virtualized keyboard through the pressing actions of the fingers. In view of being compatible with habits of pressing the keyboard of all kinds of users, the device using the interactive intelligent method based on the video images provides a supervising function of the inputting of the virtualized keyboard, and corrects differences of accuracy brought by all kinds of actions which are not the keyboard inputting action. The non-contact type intelligent inputting method based on the video images is characterized in that a user does not need any auxiliary positioning areas and auxiliary positioning objects for inputting, and the inputting action can be achieved at any position inside the working area of the image collection device. The interactive intelligent method based on the video images is low in cost, wide in applicability, and intelligently interactive. The invention further provides the realizing device based on the interactive intelligent method based on the video images.
