About this episode

Inspired by Alexander Graham Bell, Prof Danielle George attempts to beam a special guest into the theatre via hologram, using the technology found in a mobile phone. When Scottish inventor Alexander Graham Bell demonstrated the first telephone in 1876, he could never have dreamed that in 2014 we’d all be carrying wire-free phones in our pockets and be able to video chat is crystal clear HD across the world. In this lecture, Danielle will explain how these technologies work and show how they can adapted to help keep you connected to the people around you. She’ll show you how to control paintball cannons with a webcam and turn your smartphone into a microscope whilst also investigating a device that allows you to feel invisible objects in mid-air.
