Justification: Balanced Tweets

Justification is a tech-based art installation that analyses the emotional content of tweets, balancing them out with messages conveying the opposite emotion.

Created by Berlin-based art student Ann-Katrin Krenz, the installation was on show at the Resonate arts festival in Belgrade earlier this month. Its aim is to create emotional "peace" through the use of intuitive technology.

A set of scales displays the emotional balance of a trend on Twitter. The scales are connected to a machine that analyses the emotional content of tweets on a subject, identifying when there is an imbalance of emotion and sending a tweet to correct it. Krenz says she used the project to explore ways in which the spread of emotion can be measured, manipulated and controlled using technology.

Quantifying emotion in a digital world can be a tricky task without the help of indicators like body language and tone of voice. Brands are experimenting with new ways to identify and respond to consumer emotion – from emoji-based marketing campaigns, to social media personas that mimic the voices of real people.
