Abstract

Advancements in Technology aim in reduction of Human efforts to a greater extent. The objective of the project is to design a Hands-Free Text Entry System using LabVIEW. In order to assist physically handicapped persons (Bilateral Amputees in specific), a simple system is designed. Unlike previous systems which used a virtual keyboard and a webcam to detect the movements of user, we are using webcam to identify and compose the characters printed on a Sheet of paper into a String. A LASER pointer is mounted on top of camera to guide the user towards the required character. This paper contains two parts, Optical Character Recognition and composing the string obtained into a file. The OCR is developed using NI Vision Assistant for LabVIEW software-developing tool.
