In a business school classroom in Spain, a computer alerts the professor that one of her students is losing interest. This is no ordinary lecture hall. It’s the Instituto de Empresa’s “WOW” room, or the “Window on the World,” a place the Spanish business school believes is the future of the master’s in business administration. The room is a physical space where faculty members deliver course modules to an audiovisual mosaic wall of students watching via video camera. A software application scans the video streams and runs a sentiment analysis to gauge students’ reactions. It can, for example, alert a lecturer if someone is losing interest, or is angry.
