At the resurgence of virtual reality in this decade, many companies saw using your phone and its screen as the basis for VR systems as the best solution. Samsung and Oculus built the Gear VR platform. Google created the Cardboard and then the Daydream platforms. A variety of other companies, including Monster, got into the game. All of these used your phone as the center of the VR experience, rather than creating dedicated VR hardware.
The problem with this approach is that consumers seemed unwilling to care. Outside of educational venues or corporate demos, I never saw a Google Daydream in the wild. Samsung was so desperate to make the platform work, they gave Gear VR headsets away with a Galaxy S8 purchase, and owners didn't request their free hardware. In response, Samsung didn't even make the 10 series, the Galaxy S10 and the Note 10, compatible with their Gear VR headsets.
Following suit, Google announced this week that the Google Daydream View hardware had taken the eternal nap. The dumb headset, as it were, was launched in 2016 and featured VR lenses and nothing more. Visually, it was probably the best recognized of the headset hardware, as it featured the strange grey fabric on the outside. However, being recognizable does not make you successful.
With this move, the era of dumb headsets and phone-based VR is all but dead. Sure, the existing hardware is still out there, both from Samsung and Google, but with no new hardware development, there is little chance that developers will put any effort into supporting these systems. So, during any software overhaul, you can expect Daydream and Gear VR support to be dropped. Hulu, as part of their UI overhaul last month, already dropped support for Daydream, beating Google to the punch.
So, with that, the failed experiment has completed. If you want to use VR going forward, you will need to use dedicated VR hardware. Fortunately, we have standalone platforms like Oculus Go, which will allow you to use VR without a computer, just like Daydream and Gear VR did.
