Trajectory of Hand Gesture Capturing Device for Sign Language Recognition

Hand gesture is interaction between hand action and microcontroller. The gesture recognition system consist of three main modules like hand segmentation continued by hand tracking system and then by the gesture recognition from hand features. The hand gestures have not been fully explored to HCI application. It is important for achieving more gestures as the command of interface like embedded system via wireless. It detects the signal given to the controller. The limitation of the proposed trajectory recognition is that it can only recognize a letter or a number finished with a single stroke. The two main algorithms are Histogram Oriented Gradient (HOG) and Support vector machines (SVM) to recognize combination hand action. The camera is used to capturing the hand actions and then current image transfer to the microcontroller, the interface of electrical appliances is controlled by hand action.
