A Review of Vision-Based Hand Action Recognition Techniques

In recent years, with the development of artificial intelligence, hand action recognition has been widely used in human-computer interaction and virtual reality, etc. To help researchers understand the current development status of vision-based hand action recognition technology, this paper presents the latest progress in hand action recognition technology. The methods are divided into machine learning-based hand action recognition and deep learning-based hand action recognition. The article discusses the advantages of both ways and the limitations of each especially focusing on the deep learning-based recognition method. The challenges of the current hand action recognition technologies are presented based on the existing research results.
