The Happy App (Data Feelings) is an art project by Mari Nagem, that uses face detection and micro facial expression recognition to measure how computer usage affects happiness.

When running, the Happy App simultaneously triggers the computer camera and records a screenshot every 15 seconds. The pictures taken by the camera are analyzed and a connection is made between the user’s emotions and the content they are seeing on the computer.

the app can be downloaded for Mac and Windows on the project’s website: https://thehappyapp.art
