Online offers by universities are mostly limited to playing back videos of lecturers’ presentations. There aren’t any opportunities for direct interaction. Scientists at the Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institut, HHI, want to change that with their VoluProf project. This project involves 32 cameras recording the lecturer’s presentation from all angles. The video data is used to generate a photo-realistic animated avatar that appears lifelike via AR glasses, and can even answer questions.
