|Looks like Google is improving the original VR headset in this 2015 patent app so that it can communicate wirelessly with other devices. I'm guessing that would include a smartphone. (HMD is head-mounted device.)|
0085] In one example, the HMD may include a wireless communication system for wirelessly communicating with one or more devices directly or via a communication network. For example, wireless communication system could use 3G cellular communication, such as CDMA, EVDO, GSM/GPRS, or 4G cellular communication, such as WiMAX or LTE. Alternatively, wireless communication system could communicate with a wireless local area network (WLAN), for example, using WiFi. In some embodiments, wireless communication system could communicate directly with a device, for example, using an infrared link, Bluetooth, or ZigBee. The wireless communication system could interact with devices that may include, for example, components of the HMD and/or externally-located devices.
