Self-boosted Gesture Interactive System with ST-Net

In this paper, we propose a self-boosted intelligent system for joint sign language recognition and automatic education. A novel Spatial-Temporal Net (ST-Net) is designed to exploit the temporal dynamics of localized hands for sign language recognition. Features from ST-Net can be deployed by our education system to detect failure modes of the learners. Moreover, the education system can help collect a vast amount of data for training ST-Net. Our sign language recognition and education system help improve each other step-by-step.On the one hand, benefited from accurate recognition system, the education system can detect the failure parts of the learner more precisely. On the other hand, with more training data gathered from the education system, the recognition system becomes more robust and accurate. Experiments on Hong Kong sign language dataset containing 227 commonly used words validate the effectiveness of our joint recognition and education system.
