If you've never spoken on stage before, you might feel overwhelmed the first time you get up there. To help make you a bit more comfortable with the experience, Public Speaking for Google Cardboard helps simulate a crowd. This app provides a virtual, 360-degree stage complete with a captive audience that can make you feel like you're giving a real presentation. Alternatively, you can use the virtual board room for smaller-scale presentations, and you can even load your own slides. While it might seem a little silly, it's a handy way to get used to the feeling of standing in front of a small or large crowd to get over your fears before the real thing.
To use the app, you'll need a Google Cardboard unit. You can make one yourself with the official Google instructions, or you can buy pre-made kits online. The Public Speaking app is free.
