3D Sensing/Gesture Recognition and Lumentum
■The first generation of 3D sensing systems worked much like human 3D recognition in nature. A light source such as the sun bathes an object in a full spectrum of light. The eye senses reflected light, but only a limited portion of the spectrum. The brain compares a series of these reflections and computes movement and relative location.
■In a computer game where a player swings a golf club in front of 3D sensor, illumination sources in the device flood the player and surrounding area with invisible, near-infrared light. The light bounces off the player and reflects back to the device. Optical filters screen out spurious and ambient light, letting only the near-infrared spectra through to the light sensor.Interpreting differences in the light bouncing back from different parts of the play, firmware creates an electronic 3D map of the player and sends it to the computer game. The result is a very realistic gaming experience with a minimum of accessories such as remotes.
