Mixed Reality (MR) is a rapidly growing technology that is revolutionizing the way we interact with digital content. The recent release of the Mixed Reality Toolkit 3 (MRTK 3) has brought many new features and improvements to the development of AR applications. In this article, we will explore the key features of MRTK 3 and what they mean for AR development.

Key Features of MRTK 3

  • Spatial Awareness: MRTK 3 introduces a new spatial awareness system that allows for more accurate and realistic interactions between digital objects and the physical world. This feature is particularly useful for creating immersive experiences in which digital objects respond to their environment in a natural way.
  • Input System: The new input system in MRTK 3 allows for more intuitive and natural interactions with AR applications. This includes support for hand tracking and gesture recognition, as well as the ability to use multiple input sources at the same time.
  • Performance Optimizations: MRTK 3 includes a number of performance optimizations that help to improve the overall performance of AR applications. This includes support for Unity’s new Job System and Burst compiler, as well as improved memory management and reduced CPU usage.

What Does MRTK 3 Mean for AR Development?

The release of MRTK 3 brings many new opportunities for AR developers. With the improved spatial awareness and input system, developers can create more immersive and interactive AR experiences. Additionally, the performance optimizations in MRTK 3 make it possible to develop more powerful and responsive AR applications.


Mixed Reality Toolkit 3 is a powerful tool that provides developers with the tools they need to create cutting-edge AR experiences. With its advanced spatial awareness, intuitive input system, and performance optimizations, MRTK 3 is set to become the standard for AR development.
