Just in case you are yet to understand these two gadgets, read on. Windows made Oculus rift dk2 for developers and not for consumers. They don't even have a return policy that allows you to return it in case you don't like it. Yet they are still selling the device to the public. Samsung has branded it an innovators edition for developers and those who adopted it early.
Oculus DK2 has a resolution of 960 x 1080 pixels per eye as stated by Oculus. Galaxy Note 4's 5.7 inch Quad HD Super AMOLED display is what VR Gear uses as display to put a 2560 × 1440 pixels in the front of both eyes, so that on the basis of pixels per inch between DK2 and Galaxy Note 4, the one with the far better quality image will be the Note 4.
I don't know what the Gear VR weighs, since the Note 4 which weighs 6.3 oz is attached to the front, we could say that it might weigh 15.5 oz like the Oculus, when you are wearing it. The two devices are very flexible and they have soft cushion that will give you comfort since it will be covering your face. The Gear VR is available in Frost White, the Oculus Rift comes in black.
Just like Oculus Rift the Samsung Gear VR has several command controls. These consist of a touchpad, a back button, forward button. Both the Gear VR as well as the Oculus Rift tracks your activities, in an excellent way. Both gadgets consist of numerous sensing units: a compass, gyro as well as accelerometer, and also the necessary sensing unit to ensure that video games quit when you get take off the headset.
