Smaller, quieter base stations for the Vive
The final version of the system will include new base stations that are quieter and smaller than in previous versions. The base stations just need a power source, and can wirelessly connect, eliminating the need for a wire attached to the PC.
Touch sensor and trigger
The wireless controller includes a touch sensor on the top for navigation, as well as a trigger to "grip" things in the virtual reality world or fire a virtual gun.
A VR system and a phone
The Vive system comes with a front-facing camera to detect what's in front of you, as well as a microphone to let you make and receive calls.
Vive gets a better fit
Changes include a more polished finish and changes to the strap for better comfort.
Wireless controllers included
Unlike the Oculus Rift, the Vive will come with two wireless controllers. HTC and Valve say they're critical to the consumer experience and for developers building consistent games.
The polished HTC Vive
After years of development and preproduction units, HTC and Valve finally unveiled the consumer version of their Vive virtual reality system. The whole shebang will cost $799 (£689).
Vive versus Rift
The Vive will have serious competition with the Oculus Rift, which starts to ship on March 28.
