Elliptic Labs has developed touchless control technology that allows users to control devices like computers and phones without touching them. Sensors are mounted around the display that can detect 3D hand movements within the line of sight of the sensors. When a hand moves in front of the sensors, the motion is detected and translated into on-screen movements and interactions. This touchless technology provides a more durable and easier user experience compared to traditional touchscreen inputs and allows for creative gestures.
