An Online Embedded Handheld Writing System by Finger Writing in the Air

摘要

Objective/Background: Nowadays many writing systems are operated with physical touch of human fingers. The main objective of this paper is to transmit data by writing in the air using human figure. Methods/Statistical Analysis: In this work a novel method is proposed, based on the finger tip movements (gestures) captured by camera, using open CV math libraries the system translates the threshold image into time-series acceleration signals and feature vectors which recognizes characters or digits written in the air. Findings: Based on the color transformation the data is displayed in any of RGB colors on LCD display and displayed data transmits to the Mobile or Laptop through the corresponding IP addresses. Application/Improvement: It is used as a space pen, security purpose for creating the digital signatures in space.
