Published By: Blue Eyes Intelligence Engineering & Sciences Publication Pvt. Ltd. Hand Gesture Recognition Systems: A Survey

Abstract:The first mode of communication in the early ages was gesture. Later on the verbal communication was developed very well. But still non-verbal communication has its importance. Non – verbal communication is used for the physically challenged people, for different applications. For e.g. aviation, surveying, music direction etc. It is the method to interact with other peripheral devices, such as keyboard, mouse. The important steps involved in HGR systems are data acquisition, gesture modelling, feature extraction and hand gesture recognition. Different algorithm are followed by different researchers or sometimes used their own algorithm. This paper studies different methods of HGR and finally the desired characteristics of a robust and efficient hand gesture recognition system have been described.
