INTRODUCTION
Gesture recognition has emerged as one of the most important research areas in the field of motion-based image processing and recognition. The potential of vision-based human- computer interfaces for visual communication has increased dramatically during recent years and gesture recognition systems promise to play a major role in these scenarios. Although the problem of gesture recognition can be facilitated by using sensors for tracking body parts, or data gloves, clearly the most desirable interface would be a purely vision-based gesture recognition system, because this would lead to a mostly unrestricted visual communication process for the user. Identification of gestures using only image information is however the most demanding and challenging approach to gesture recognition
The use of hand gestures provides an attractive alternative to cumbersome interface devices for human-computer interaction (HCI). In particular, visual interpretation of hand gestures can help in achieving the ease and naturalness desired for HCI.The aim of the project is
“Controlling Computer Using Hand Gesture Recognition ”
Problem Statement
The goal of our project is to develop a real-time system capable of understanding commands given by Hand gestures. The user must be able to communicate to computer, all basic commands required by a human-computer interface.
Basic purpose is to develop system such that we are able to operate computer with the help of hand gestures without using mouse. This project helps us in introducing new computer interface, provided interface will be more natural and user friendly. It also reduces physical contact with devices and minimizes hardware required for interfacing.
Scope
In future project can be used for multimedia applications like playing games without using mouse also all keyboard operations can be performed using this project. But enhancing this project is quite complex and difficult, so lots of hard work is required.
LITERATURE SURVEY
A simplification used in similar type of projects, which was not found in any recognition methods researched, is the use of a wrist band to remove several degrees of freedom. This enabled three new recognition methods to be devised. The recognition frame rate achieved is comparable to most of the systems in existence (after allowance for processor speed) but the number of different gestures recognized and the recognition accuracy are amongst the best found. Figure shows several of the existing gesture recognition systems along with recognition statistics and method.
System Deployment and Maintenance
This makes for the final phase of the waterfall model, where the software is deployed at the user side, after it has undergone thorough testing. After the deployment of the software, routine maintenance work is carried out. In maintenance phase software is repaired if any problem occurs and returned back to user. There must be maintenance phase after delivery of software as it beneficial for maintaining good relationship with customers.
