Lewis’ research involves using mathematical tools to measure happiness on Twitter. He and several other researchers designed the hedonometer to visualise the happiness of the Australian ‘Twitterverse’ in real-time.
A few years ago, he built himself a small version of the hedonometer, which he called a hedoneggmeter.
But the exhibit will be more than just a big start to the exhibition, or a conversation starter for that matter. Lewis also hopes it will help him advance his research.
In essence, his research assigns scores to certain words used in Twitter posts. Those scores help him show whether the twitterverse is happy or not.
This new exhibition will also allow visitors to rate the words with a continuous slider, rather than just using 1 to 9 integer values.
“This should let us explore the scores with greater precision than before. Visitors can also contribute information about their age and gender, which will allow us to study how different demographics react to different words. That will help us improve future versions of the hedonometer,” said Lewis.
The Hedonism exhibition opens to the public on Saturday 25 May at MOD.
