Michael Rosen gets advice from Erica Dhawan on the best ways to communicate on-screen, as people work and live more in zoom, text, social media and email rather than meeting up. We need to find new ways of talking to each other 'virtually'. Erica Dhawan is the author of Digital Body Language: How to Build Trust and Connection, No Matter the Distance. Produced by Beth O'Dea for BBC Audio in Bristol.
