90% of everything we say is communicated nonverbally. So can we ever get across how we really feel over chat apps, emails or conference calls? This week Damian talks to Rana el Kaliouby who, as founder and CEO of Affectiva, has pioneered a digital software that can read and analyze human emotion in real time. The pair discuss how tracking viewer response helps brands like Coke and Dove make better, more-inclusive ads, and why a future grounded in digital comms might see us emotionally regress.
