Lauren Mccarthy a artist and programmer. She focuses on the different human interactions and how the world around us affects our social relationships. In her talk at the 2017 Gray Area Festival she introduces a project that she and others worked on. Basically it is a watch that is connected to an app which allows you to determine and notice how you feel around others around you. The app will tell you if you are feeling stress, sad, happy or any other emotions around the people you see everyday. If the person makes you unhappy then you can take actions into account to delete the person. This project is to help people see and know their cause of emotions so that they can improve their mental health and have a positive life style. The name of the product is pplkpr. 

Here are some images of the project
