This work explores the potential of using OpenCV and MediaPipe to develop gesture-based interaction modules aimed at enhancing human–computer interaction. The five preliminary modules in this study include finger count, finger tracker, air canvas versions 1 and 2, color selection and graphical tools, and a gesture-based computer control system. These modules using rudimentary image processing from the OpenCV module for images and MediaPipe for gesture recognition are a path toward fully realizing mapped intent to allow for a smoother integration of human intent and machine response. This investigation not only enhances the development of gesture recognition technology but also provides directions for future studies to enhance the gesture-based interaction on digital devices.
