Hand input method

Abstract

The invention discloses a hand shape input method. The mobile phone camera is used to collect hand shape action videos, and the video data stream is processed at the same time in the background. The number of resampled images per second is designed to judge whether there is an input partition hand shape, and the data is re-divided by the partition hand shape. , the hand-shape input action video after partition hand-shape recognition is divided into a series of input hand-shape photo sequences; the hand-shape input video action captures the photo sequence, sequentially performs skin color recognition, adjusts the size of the hand-shape core area, and converts the color space to generate an image sequence , and then judge the positional relationship between the thumb and other fingers in the image according to the initially predetermined image features, and complete the left and right hand recognition and hand shape judgment. The invention is a coding method for inputting various symbols into a computer or other equipment using hand shape, which is convenient for human-computer interaction application in special crowds and special situations.

Description

technical field [0001] The invention relates to the field of human-computer interaction applications, in particular to a hand shape input method. Background technique [0002] Input Method (Input Method) refers to the input coding method rather than the software that realizes text input. The input method generally refers to the input method of the ordinary keyboard of the computer or the keyboard on the mobile phone. In a broad sense, the input method also includes handwriting, voice, OCR (Optical Character Recognition, optical character recognition) scanning reader, speed recorder and other input methods. Handwriting recognition utilizes the computer's word recognition function to identify text or other symbols from the user's handwritten characters. Speech recognition uses a microphone and speech recognition software to interpret text. There are many types of OCR software, such as Tsinghua OCR, which is commonly used. After the system recognizes the graphics, the system ...

AI Technical Summary

Problems solved by technology

Therefore, vision-based hand gesture input technology has far-reaching research significance. Hand gesture recognition technology has long been studied in depth along with human body characteristics such as face, iris, gait, and palm prints as biometric technology, but has not yet been developed. is directly applied to the input method
