Designed for the Google Cardboard, this launcher allows you to change games/apps hands-free

Cardboard Home is an Android launcher designed for use with the Google Cardboard virtual reality headset. Cardboard Home is intended to replace a regular launcher when the user places their device inside a Google Cardboard viewer. Unlike a regular launcher, Cardboard Home uses side by side 3D to display a launcher interface that is useable while inside a Google Cardboard.
