No, I'm talking about representing your real keyboard, in it's correct relative space, in your virtual space, so you can correctly use it in reality. If there was a front facing camera on the VR set, you would just pass the image of keyboard and your hands through when in that entry mode, but without that you approximate the keyboard position and the position of your hands (with extra hardware, or a leap motion, etc), and represent them correctly in VR so they can be used as expected.
