Tango Concepts Tango 概念

Tango is a platform that uses computer vision to give devices theability to understand their position relative to the world around them. It’ssimilar to how you use your eyes to find your way to a room, and then to knowwhere you are in the room and where the floor, the walls, and objects aroundyou are. These physical relationships are an essential part of how we movethrough our daily lives. Tango gives mobile devices this kind ofunderstanding by using three core technologies: Motion Tracking, Area Learning,and Depth Perception.


Motion Tracking overview 运动跟踪概述

Motion Tracking means that a Tango device can track its own movementand orientation through 3D space. Walk around with a device and move itforward, backward, up, or down, or tilt it in any direction, and it can tell youwhere it is and which way it’s facing. It’s similar to how a mouse works, butinstead of moving around on a flat surface, the world is your mousepad.

Area Learning overview 区域学习概述

Human beings learn to recognize where they are in an environment by noticingthe features around them: a doorway, a staircase, the way to the nearestrestroom. Tango gives your mobile device the same ability. With MotionTracking alone, the device “sees” the visual features of the area it is movingthrough but doesn’t “remember” them.


With Area Learning turned on, the device not only remembers what it sees, itcan also save and recall that information. When you enter a PReviously savedarea, the device uses a process called localization to recognize where you arein the area. This feature opens up a wide range of creative applications. Thedevice also uses Area Learning to improve the accuracy of Motion Tracking.

Depth Perception overview 深度感知概述

With depth perception, your device can understand the shape of yoursurroundings. This lets you create “augmented reality,” where virtual objectsnot only appear to be a part of your actual environment, they can also interactwith that environment. One example: you create a virtual character who jumpsonto and then skitters across a real-world table top.
