Effect of sparsity-aware time–frequency analysis on dynamic hand gesture classification with radar micro-Doppler signatures [PDF]

, 2018
Dynamic hand gesture recognition is of great importance in human-computer interaction. In this study, the authors investigate the effect of sparsity-driven time-frequency analysis on hand gesture classification.

Secret hand gestures in paintings.

Acta bio-medica : Atenei Parmensis, 2019
During the Renaissance period, hands were as important a focus of attention as the face was, because they were the only other visible area of the body. Hence, representation of the position of the hands became a decorative element that was almost as important as the face.

Hand gesture recognition

Global Research and Development Journals, 2020
Evolution of user interfaces shapes the change in the human-computerinteraction devices. As three-dimensional (3-D) applications take place, theneed for a new type of interaction device arises since traditional devices suchas mouse, keyboard, joystick, etc? become inefficient for interaction withinthese virtual environments.

Hand Gesture Recognition

REST Journal on Data Analytics and Artificial Intelligence
The "Real-Time Hand Gesture Recognition System" aims to enhance human-computer interaction using computer vision and machine learning techniques. Using the webcam for real-time video capture, the system uses OpenCV to process each frame in real-time. Thus, it recognizes hand gestures using models such as Cvzone's, Hand Detector or Mediapipe.
