A digital input method based on gesture

Abstract

The invention provides a digital input method based on gestures and belongs to the field of computers. According to the method, a virtual interface which is an operator gesture operation area is constructed and can change along with the body position or the posture of an operator; N digits are sequentially input through the virtual interface, or N virtual interfaces are generated, one digit is input into each virtual interface, and the N virtual interfaces form a virtual interface group; a display screen is defined as a physical interface, and the space between the operator and the physical interface is defined as a physical space; the physical space comprises the virtual interface and a non-virtual interface; the gestures of the operator are effective and perceptible within the virtual interface and ineffective within the non-virtual interface; the digits are input through the virtual interface group.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a gesture-based digital input method. Background technique [0002] Inputting numbers with gestures has always been one of the difficult and key issues in gesture interaction theory and application research, and it is also one of the pain points in industrial fields such as smart home appliances. [0003] At present, gesture numbers are generally used to input numbers with different gestures. It first recognizes gesture images, and then interprets different gestures as different numbers. The main problems of this method are: (1) The recognition rate is affected by many factors. (such as distance, feature extraction, recognition operator, etc.), especially for gestures with similar shapes, it is difficult to distinguish them by ordinary methods; (2) when multiple people operate at the same time, they are easy to interfere with each other; (3) there is a "MidasTouch problem" ....
