Study on Hand Gesture Recognition?

To access any information user has to repeat keyboard and mouse actions which results in waste of time and it is inconvenient to use. So hand gesture recognition has received attention in the recent years. Using hand gesture we can easily interact with any device robustly. In this paper we have surveyed methods of hand gesture recognition like coloured glove, vision based depth camera etc. This paper focuses advantages and disadvantages of all these methods, and process of segmentation, thresholding which are required for hand gesture recognition methodology. We also present the applications from robot control to sign language recognition of hand gesture are studied.
