The HTV Vive is is an upcoming virtual reality head-mounted display being developed in co-production between HTC and Valve Corporation. It is also part of Valve Corporation's SteamVR project.
The Vive has a refresh rate of 90 Hz, requiring content to be rendered at 90 frames-per-second. The device uses two screens, one per eye, each having a resolution of 1080x1200. The Vive has more than 70 sensors including a MEMSgyroscope, and laser position sensors nicknamed "Lighthouse" base station. The Lighthouse system uses simple photosensors on any object that needs to be captured, this is combined with two, to avoid occlusion problems, lighthouse stations that sweep structured lightlasers within a space.
Samsung GearVR + Note4
The Samsung Gear VR is a mobile virtual reality device developed by Samsung Electronics in collaboration withOculus VR. A compatible Samsung Galaxy device (Galaxy Note 4 or Galaxy S6/S6 Edge), sold separately, acts as the headset's display and processor, while the Gear VR unit itself contains the high field of viewlenses as well as a custom IMU for rotational tracking which connects to the smartphone via micro-USB. This IMU is more accurate and well calibrated with lower latency than internal smartphone IMUs.
The Oculus Rift DK2 headset has a resolution of 960×1080 per eye, a low-persistence OLED display, 75 Hz refresh rate and positional tracking.
