Microsoft Kinect uses infrared sensors to determine movement
However, game developers are not interested in creating games with lots of body movement. Because they are used to designing games based solely on traditional handles and there is no compelling reason to change. So very few games came out using Kinect's motion capture feature.
Big games, such as Halo, never want to create the Kinect-style action style, or at least to the extent that developers need this device's feature.
From a broader perspective, Microsoft wants to use Kinect to play video and audio via Skype and Twitch, but this obviously doesn't guarantee Kinect's existence.
Even though it's a hardware device, Kinect's depth-sensing is still used, for example, Microsoft uses the technology of Kinect camera on Hololen virtual reality headsets.
Kinect's 3D sensor technology is not only used by Microsoft. It is also available on the upcoming iPhone X phone with Face ID, infrared face detection technology.
Kinect, though dead, its applications still exist and extend much more than the scope of video games that failed to exploit.
