Fear of public speaking is quite common, and chances are you either know someone who has it or you suffer from the phobia yourself. This smart glass app called Rhema, created by researchers from the Human-Computer Interaction Group at the University of Rochester, was designed for people who need a bit of help addressing crowds. Rhema can listen as you speak, upload your recorded voice to a server, analyze its pace and volume, and then give you feedback in real time. To test it out, the team had 30 subjects try out several different feedback systems installed on Google Glass. These include ones that shows a traffic lights-like scheme and another that uses graphs.
