Human computer interaction

Gesture-Based Human Computer Interaction (GB-HCI) is a technology that enables users to interact with computers naturally through body movements, without the need for physical input devices like a mouse or keyboard. It captures gestures using sensors or cameras and processes them through image analysis and pattern recognition techniques. The recognized gestures are then translated into corresponding commands that allow the computer to respond and perform actions. This form of interaction makes computing more intuitive, efficient, hygienic, and immersive. It is widely used in areas such as virtual reality, gaming, robotics, smart environments, and assistive technologies, improving accessibility and user experience.
