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.

Tango是一個使用計算機視覺的平臺，讓設備能夠了解他們相對于周圍世界的位置。它類似于你如何使用你的眼睛找到你的房間的方式，然后知道你在房間里的地方，墻壁和你周圍的對象在哪里。這些身體關系是我們如何在我們的日常生活中不可或缺的一部分。Tango通過使用三種核心技術為移動設備提供這種理解：運動跟蹤，區域學習和深度感知。

Motion Tracking overview 運動跟蹤概述

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.

運動跟蹤意味著Tango設備可以通過3D空間跟蹤其自身的運動和方向。用設備走動，向前，向后，向上或向下移動，或向任何方向傾斜，它可以告訴你它在哪里，它面對的方式。它類似于鼠標的工作原理，但不是在平坦的表面上移動，世界是你的鼠標墊。

Area Learning overview 區域學習概述

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.

人類通過注意它們周圍的特征來學習識別他們在環境中的位置：門口，樓梯，通往最近的洗手間的方式。探戈給您的移動設備相同的能力。僅使用運動跟蹤，設備“看到”它正在移動通過的區域的視覺特征，但不“記住”它們。

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.

啟用區域學習后，設備不僅會記住它看到的內容，還可以保存和調用該信息。當您輸入先前保存的區域時，設備使用稱為本地化的過程來識別您在該區域中的位置。此功能打開了廣泛的創意應用程序。該設備還使用區域學習來提高運動跟蹤的準確性。

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.

使用深度感知，您的設備可以了解您的周圍環境的形狀。這允許您創建“增強現實”，其中虛擬對象不僅看起來像是您的實際環境的一部分，他們也可以與該環境交互。一個例子：你創建一個虛擬角色，跳到現實世界的桌面上然后跳過。
