Microsoft has released Emoji8, a sample UWP application that uses Windows Machine Learning to evaluate your facial expressions while you imitate a random selection of emojis.

The app takes in a video feed from your computer’s webcam and evaluates the images with the FER+ Emotion Recognition model version 1.2 locally on your machine. You can tweet a gif summarizing your best scoring pics when you have an internet connection and continue playing even when you don’t have one.

Besides the fun, the app gives you an end-to-end example of how you can use the Windows ML APIs to create simple yet magical experiences.

You can download Emoji8 from the Microsoft Store, but make sure you’re using the Windows 10 October 2018 Update.
