Gesture Recognition based Fingertip Air Writing to Text Convertor using Image Processing and HCI

Gesture Recognition based fingertip air writing to text converter which permits to write and sketch text characters in fore of a web camera in the laptop computer over the air. The two main tasks of proposed methods are a blue-colored object is taken in the hand. To perceive the written characters from video frames, a blue-colored object is being tracked and optical English text reformation is applied over the plotted images. Additionally, a stylus pen, touchscreen pen, keyboard, glove or any other device is not required for giving input characters a habitual human-computer interaction is developed to address it. Application based on Open CV with the python language is designed for experimental purposes. It is relevantly a straightforward software-based approach, which is effortless and effective. Moreover, it requires a web camera and a blue-colored object other than hardware or any other sensors.
