Gesture-based control

Definition

Gesture-based control is a technology that allows users to interact with devices and systems through physical movements, typically involving hand or body gestures. This method of interaction utilizes sensors and cameras to interpret user actions, enabling a more intuitive and immersive experience, especially within the expanding landscape of connected devices known as the Internet of Things (IoT). Gesture-based control enhances user engagement by allowing seamless navigation and command without the need for traditional input methods like keyboards or touch screens.
