Since its early inception, virtual reality has offered an escape. Donning a headset can transport you to a brand new world, full of wonderment and excitement. Or it can let you explore a location too dangerous for human existence.  Or it can even just present the real world to you in a new manner. And now that we have moved past the era of bulky goggles and clumsy helmets, the hardware is making the aim of unfettered escapism a reality.

In this article, we present a roundup of the modern VR hardware systems. Each product is presented giving an overview of the device, and its price as of February 2018. Use this information to compare systems and find the device which best suits your personal needs.

There has been an explosion of VR hardware in the last three years. They range from cheaply made housings around a pair of lens to full headsets with embedded screens creating a 110-degree field of view. Each device offers distinct advantages and use cases. Many have even dropped significantly in price over the past 12 months making them more accessible to a wider audience of users. Following is a brief overview of each device, ranked in terms of price and complexity.

Google Cardboard

Cardboard VR is compatible with a wide range of contemporary smartphones.

Google Cardboard’s biggest advantage is its low cost, broad hardware support, and portability. As a bonus, it is wireless.

Using the phone’s gyroscopes, the VR applications can track the user in 360 degrees of rotation.

While modern phones are very powerful, they are not as powerful as desktop PCs. But the user is untethered and the systems are lightweight:

Google Cardboard

Cost: $5-20 (plus an iOS or Android smartphone)

Google Daydream

Rather than plastic, the Daydream is built from a fabric-like material and is bundled with a Wii-like motion controller with a trackpad and buttons.

It does have superior optics compared to a Cardboard but is not as nice as the higher end VR systems.

Just as with the Gear VR, it works only with a very specific list of phones:

Google Daydream

Cost: $79 (plus a Google or Android Smartphone)

Gear VR

Gear VR is part of the Oculus ecosystem. While it still uses a smartphone (Samsung only), the Gear VR Head-Mounted Display (HMD) includes some of the same circuitry from the Oculus Rift PC solution. This results in far more responsive and superior tracking compared to Google Cardboard, although it still only tracks rotation:

Cost: $99 (plus Samsung Android Smartphone)

Oculus Rift

The Oculus Rift is the platform that reignited the VR renaissance through its successful Kickstarter campaign. The Rift uses a PC and external cameras that allow not only rotational tracking but also positional tracking, allowing the user a full VR experience. The Samsung relationship allows Oculus to use Samsung screens in their HMDs.

While the Oculus no longer demands that the user remain seated, it does want the user to move within a smaller 3 m x 3 m area. The Rift HMD is wired to the PC.

The user can interact with the VR world with the included Xbox gamepad, mouse, and keyboard, a one-button clicker, or proprietary wireless controllers:

Oculus Rift

Cost: $399 plus $800 for a VR-ready PC

Vive

The HTC Vive from Valve uses smartphone panels from HTC.

The Vive has its own proprietary wireless controllers, of a different design than Oculus (but it can also work with gamepads, joysticks, mouse/keyboards).

The most distinguishing characteristic is that the Vive encourages users to explore and walk within a 4 m x 4 m, or larger, cube:

Cost: $599 plus an $800 VR-ready PC

Sony PSVR

While there are persistent rumors of an Xbox VR HMD, Sony is currently the only video game console with a VR HMD.

It is easier to install and set up than a PC-based VR system, and while the library of titles is much smaller, the quality of the titles is higher overall on average. It is also the most affordable of the positional tracking VR options. But, it is also the only one that cannot be developed on by the average hobbyist developer:

Playstation

Cost: $400, plus Sony Playstation 4 console

Microsoft’s HoloLens

Microsoft’s HoloLens provides a unique AR experience in several ways.

The user is not blocked off from the real world; they can still see the world around them (other people, desks, chairs, and so on) through the HMD’s semitransparent optics.

The HoloLens scans the user’s environment and creates a 3D representation of that space. This allows the Holograms from the HoloLens to interact with objects in the room. Holographic characters can sit on couches in the room, fish can avoid table legs, screens can be placed on walls in the room, and so on.

The system is completely wireless. It’s the only commercially available positional tracking device that is wireless. The computer is built into HMD with the processing power that sits in between a smartphone and a VR-ready PC.

The user can walk, untethered, in areas as large as 30 m x 30 m.

While an Xbox controller and a proprietary single-button controller can be used, the main interaction with the HoloLens is through voice commands and two gestures from the user’s hand (Select and Go back).

The final difference is that the holograms only appear in a relatively narrow field of view.

Because the user can still see other people, either sharing the same Holographic projections or not, the users can interact with each other in a more natural manner:

Microsoft Hololens

Cost: Development Edition: $3000; Commercial Suite: $5000

Headset costs and comparison across various features

The following chart is a sampling of VR headset prices, accurate as of February 1, 2018. VR/ AR hardware is rapidly advancing and prices and specs are going to change annually, sometimes quarterly. As of now, the price of the Oculus has dropped by $200:

Choosing which HMD to support comes down to a wide range of issues: cost, access to hardware, use cases, image fidelity/processing power, and more. The previous chart is provided to help the user understand the strengths and weaknesses of each platform.

There are many HMDs not included in this overview. Some are not commercially available at the time of this writing (Magic Leap, the Win 10 HMD licensed from Microsoft, the Starbreeze/IMAX HMD, and others) and some are not yet widely available or differentiated enough: Razer’s Open Source HMD.
