HTC Vive VR Headset
Having pretty much identical specs as the Rift, the biggest difference is the $799 USD price point. However, the Vive is consider the most complete VR package because of several standard features offered that other headset don't.
The Vive stands out because comes with motion controllers that completely change how users interact with VR. The motion controllers allows the user to reach out and seemingly feel and interact within the VR world. If controllers just aren't interactive enough, there's also a virtual reality gloves created by Manus.
The Vive comes included with three games, Job Simulator, Tilt Brush, and Fantastic Contraption. The awesomest feature is the front-facing camera on the Vive headset. The camera casts a blue outline on the walls and objects when you get too close. It acts like a safety net allowing the user to get up from their seat and explore a 3D environment (Vive has a 15x15ft tracking space using 2 included base stations). If you'e looking for unlimited movement like walking or jumping, Virtuix and Cyberith has a VR motion platform that lets the user walk, run, strafe, crouch, jump, or sit.
Same as the Rift, you'll need a powerful desktop or laptop with at least a GeForce GTX 970 or comparable graphics card to operate the Vive. Engadget has an in-depth article comparing the Vive and Rift that is worth checking out.
