A Systematic Review of Computer Vision-Based Virtual Conference Assistants and Gesture Recognition

In the process of introducing gesture recognition, it is essential to explore its technical background and implementation methods. Gesture recognition algorithms based on deep learning perform exceptionally well when processing real-time video streams. These algorithms can extract gesture features and classify them to identify user intentions. For instance, analyzing gesture images using Convolutional Neural Networks (CNN) can effectively enhance recognition accuracy and real-time performance. Additionally, combining optical flow methods with object detection techniques allows for real-time tracking of user hand movements, leading to more precise recognition results. Factors such as changes in ambient lighting, cluttered backgrounds, and the diversity of user gestures can all impact recognition accuracy. Therefore, researchers need to continuously optimize algorithms to improve the robustness and adaptability of the system. At the same time, when designing virtual conference assistants, the user interface's friendliness and usability should also be considered, enabling users of varying technical skill levels to use the system with ease.
