With a goal of not making people sick, ION VR, a Boise, ID based company, demonstrated at International CES 2016 a virtual reality headset that is modular and can adapt as technology changes. It leverages the smart phone one already has and can be adapted as new smart phone models are released. Most important, are the optics, which are designed to prevent virtual reality-caused, motion sickness experienced by some and allow for viewing of longer form virtual reality content.
