Once again, congratulations for getting through the chapter. Despite implementing the same project, we have covered a lot. Throughout this chapter, we looked at how we can leverage the open source HolotToolkit project to accelerate our development. We also looked in depth at how to better understand the scanned environment, allowing us to make use of it. We emphasized the importance of user feedback and discussed briefly the important concept of intelligently assisting the user to improve the user experience. We will continue this theme in the next chapter, where we look at voice as our main input.
