What is 3D
Sensing?
3D sensing technology
gives digital devices the
ability to observe a scene
in three dimensions. And
translates into a synchro-
nized image stream
(depth and color).
3D Sensing
Basic 3D Sensing System Components
Illumination Sources LEDs or laser diodes typically generating infrared or near-infrared light which is often optically modulated to improve the resolution performance of the system. Controlling Optics Optical lenses help optimally illuminate the environment and focus reflected light onto the detector surface. A band pass filter lets only reflected light that matches the illuminating light frequency reach the light sensor. Depth camera A high performance optical receiver detects the reflected, filtered light, turning it into an electrical signal for processing by the firmware. Firmware very-high-speed ASIC or DSP chips process the received information and turn it into a format which can be understood by the end-user application such as video game software.

How 3D Sensing/Gesture Recognition
Works?
It works like human 3D recognition in nature. A light
source 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, 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 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.
Applications Capture accurate DIMENSIONS of objects and envi-
ronments with the push of a button. Control onscreen interaction of electronic devices
with simple HAND MOTIONS and GESTURES.
Advanced FACE RECOGNITION system with im-proved accuracy and security.
Detailed full body GAMING system where the play-er controls the virtual environment with his own body movements rather than using a controller.
