What is motion tracking?
Introduction to motion tracking
AR motion tracking generally refers to the function of tracking the six degrees of freedom (6DoF) position and orientation of a device (such as a smartphone, tablet, or smart glasses) relative to the environment in real-time through computer vision and sensor fusion algorithms. Some manufacturers or operating system-native mixed reality SDKs provide similar motion tracking functions, such as Apple's ARKit, Google's ARCore, and Huawei's AR Engine. On some smart glasses, manufacturers provide similar motion tracking functions. On the WeChat Mini Program platform, WeChat has opened 6DoF AR capabilities that are functionally similar to motion tracking.
The proportion of devices supported by manufacturers or operating systems is relatively low. To enable more devices to support motion tracking, EasyAR's Motion Tracker utilizes computer vision and visual-inertial simultaneous localization and mapping (VI-SLAM) technology to achieve real-time 6DoF tracking on more devices.
