The Valve Index Headset and Controllers is a new virtual reality gear that was created by Valve and released on June 28th, 2019. It is competing with the HTC Vive's VR gear and the Oculus' VR Gear. A large improvement to the VR Headsets known today and the revolutionizing finger-tracking controllers.
The displays of the inside the headset are now LCDs instead of OLED that have a resolution size of 1440 x 1600 per display. It's defintely a higher resolution than the HTC Vive's resolution which is 1080 x 1200. The change from OLED to LCD means there are more sub-pixels which further boost the resolution. The headset comes with the 'nearfield off-ear speakers' which means that the speakers are dangling closely near the person's ear. The Field of View is higher than the HTC Vive due to the eye-relief adjustment feature that Valve implemented in onto the headset.
The Valve Index controllers can track each individual finger by using sensors on the side of the controller to track the exact movement of the user's fingers. With individual finger tracking, the user can feel more immersive when interacting with the virtual reality environment since it almost feels quite natural when picking up an object as they would in real life.
