Google Cardboard was introduced in 2014 as an inexpensive, easy to use virtual reality headset. The entire unit consists of a cardboard housing, velcro, and two lenses. To use the headset, a user places a smartphone in front of the lenses, while relying on a mobile application running on the phone to replicate a virtual environment. As the user’s head turns and moves, the application adjusts based on the phone’s sensors that detect movement.

Users can order a unit for as little as $19 from one of Google’s partners. Just last month Google announced it has shipped over 5 million Cardboard viewers.

In comparison, Facebook’s (FB) Oculus Rift headset is available for preorder with a price tag of $599, and that doesn’t include the Windows computer required to power the headset.

According to the Financial Times report, Google’s (GOOG) next viewer will be a more robust VR headset akin to Samsung’s Gear VR. The plastic housing will still rely on a smartphone for processing power and picture quality, however the new headset will gain improved sensors and lenses.

Samsung’s (SSNLF) Gear VR headset is limited in compatibility to Samsung’s own smartphones, whereas current Google Cardboard units works with any smartphone—Android or iOS—under six inches. The new viewer will also carry broader handset support.

Additionally, Google is adding support for VR headsets directly into the Android operating system according to the report. Currently, Google Cardboard apps are used to power the entire experience without the operating system providing any sort of VR optimization when a Cardboard app is running.

Latency—the amount of time it takes for a screen to refresh—can lead to motion sickness during VR session due to the delay in head movement and the image updating on the viewer. By improving upon the software experience combined with better sensors baked into new hardware, Google is hoping to improve the overall experience and reduce latency.
