Presentation Remote is a Chrome app that allows you to use your smartphone to remotely control your presentations on Google Drive, Prezi, Scribd, Slideshare and Dropbox. Of course, to be able to do that you will have to have their app called De Modo installed on your phone. The app is free and is available for both iOS and Android. Here is how it works:
on your Computer :
Add the Presentation Remote app from the Chrome Web Store to the browser or visit presentationdocs.com on Chrome or Safari.
Click the “Connect” button in the left menu and a QR code will show up.
On your mobile device:
Install “de Mobo” on Android 2.3+ or iPhone 4+.
Click “Create Connection” on your mobile device to scan that QR code.
Make sure the mobile device and computer are using the same wifi network for reliable performance.
