What makes the Vive Focus really stand out for me is the head strap. Adding a battery and embedded display and processor to these headsets adds some understandable weight, and to solve this the head strap is designed to hug your noggin perfectly. Where most headsets are starting to adopt the "halo" design that hugs your head like a crown, this strap system moves down to grab closer to the base of your skull. There's a gear to tighten the strap down across your head, ensuring the pressure is away from your eyes and nose. As a result, it's one of the most comfortable headsets I've ever put on, and does a great job making it easy to take on and off.
When asked if the Vive Focus would ever come to the US, the response was an almost programmed shoulder shrug.
As freeing as this comfortable 6DoF headset feels, that's exactly how restricting the 3DoF controller is to use. You can rotate the controller around in your hand and point at things like you would on Daydream or Gear VR, but if you move your arms around like you would a Vive or PlayStation VR, nothing happens in the headset. Instead, you have a trigger and touchpad for interacting with the world around you. Spark of Light, the award-winning game I was able to demo with this headset, worked hard to take advantage of this limitation. The game walks a character through a series of puzzles happening all around you, making it so you enjoy turning around and leaning in on the details while only occasionally clicking on specific set pieces to set up the next part of the puzzle.
When asked if the Vive Focus would ever come to the U.S., the response was an almost-programmed shoulder shrug. It's not impossible, but doesn't seem overly likely anytime soon. Google is fairly focused on Daydream Standalone everywhere outside of China, creating an opportunity for HTC to build a platform with Vivewave that lots of manufacturers can participate in over there. Which is a shame, because if that headset were available for me to purchase today I would absolutely do so.
