International Journal of Latest Trends in Engineering and Technology · 2016
Gestures are expressive meaningful body motions -i.e. the movements of any part of the body such as fingers, hands, arms, head, face, or body itself with the intent to convey some required information or interact with the environment.So many aspects of gestures are there that may be relevant and therefore may need to be represented explicitly.It can be categorized as follows: Spatial information -Where it occurs, locations a gesture refers to. Pathic information -The path that a gesture takes. Symbolic information -The sign that a gesture makes. Affective information -The emotional quality of a gesture.The number of senior citizens and handicapped people are increasing and accordingly the need of human friendly wheelchair is also consistently increased.Traditional power wheelchairs are having buttons or joysticks for controlling the wheelchair but some disable people are so affected that they can't even apply that much force because of psychomotor problems.Human interface of intelligent wheelchair for easy operation is the most popular research area.Yi Zang, Jiao Zang [1], proposed an intelligent wheelchair system based on hand gesture recognition again but they were used neural network concept and trained the system, In this article that factor by using classification techniques has been removed and real time approach is used.
