Images from police body camera footage with red and blue squares over important parts of the image. — Princeton researchers have found that AI models do not consistently analyze police bodycam footage accurately. Images above show different types of interactions, highlighting some that are easier or harder for AI tools to correctly identify. Images courtesy of the researchers

Four students hold posters printed with large cards to be used in a game about data privacy. — In the Keller Class “Critical Design Studio,” students learned structured techniques for intervening in complex societal challenges. In one project, students created a card game to help players take more active control of the privacy of their personal data online. “Learning about data privacy is usually abstract,” said economics major Chloe Chan, third from left. “We wanted to turn those abstract concepts into something you can see, feel, and react to in real time.” Chan said. The students finished the semester by testing the game with fellow students and professionals at Princeton’s Center for Information Technology Policy. “This was a really, really fun class,” Chan said. Vertesi “opened my mind to how big the field of design is.” (Photo courtesy of Chloe Chan)
