Abstract: The growth of touchless technologies has created opportunities for clean communication between humans and computers. This paper introduces GestKey, a system that lets you type using hand gestures and MediaPipe Hand Landmark detection. With GestKey users can input text without touching anything. The system uses a webcam to capture hand movements and find finger positions.It does this by using a -trained model that tracks hands.By linking gestures to keyboard inputs users can interact with a keyboard on the screen. GestKey aims to make things more accessible.It reduces the need for keyboards. Makes it easier to use in situations where touch input is not convenient or safe. The system processes hand landmark coordinates over time. It uses algorithms to recognize gestures and convert them into keystrokes quickly. It also includes techniques to filter out noise and stabilize gestures for accuracy. This helps prevent inputs.Experimental results show that GestKey works well in lighting conditions and backgrounds. This makes it suitable for uses like technologies, public interfaces and smart environments. Overall GestKey provides a cost and user-friendly way to type without contact. It supports the growing field of gesture-based interaction systems, like GestKey.
