Center node: "hand gesture recognition based text input method for ar vr wearable devices"
  Abstract: Static and dynamic hand movements are basic way for human-machine interactions. To recognize and classify these movements, first these movements are captured by the cameras mounted on the augmented reality (AR) or virtual reality (VR) wearable devices. The hand is segmented using segmentation method and its gestures are passed to hand gesture recognition algorithm, which depends on depth-wise separable convolutional neural network for training, testing and finally running smoothly on mobile AR/VR devices, while maintaining the accuracy and balancing the load. A number of gestures are processed for identification of right gesture and to classify the gesture and ignore the all intermittent gestures. With proposed method, a user can write letters and numbers in air by just moving his/her hand in air. Gesture based operations are performed, and trajectory of hand is recorded as handwritten text. Finally, that handwritten text is processed for the text recognition.
