Virtual reality is a up and coming technology that allows for a fully immersive experience with your phone. All you need is a smart phone such as an iPhone and a virtual headset to try it out for yourself. Cardboard virtual reality headsets are an affordable way to enjoy virtual reality instead of investing in a high end alternative. Before you can start enjoying Google VR iPhone apps and media sources, you need to assemble your headset first. Carefully bend the cardboard along the lines to create even creases before securing the sides in place into the slots. Be sure to place the lens properly and secure them in the holes for optimal viewing. You may want to clean the lens prior to placing them to ensure that the view is clear and free of debris.
