Technical meaning software, hardware, or both? Software side we need better graphics and ways to make those graphics. Laser scanning and imaging could be a lot better than it is today. I suspect by the time I die we'll have a 3D model of the vast majority of the planet, much like we have street view now. Hardware side we need better interaction. Providing tactile feedback and textures is a big one. I think the next logical step from Oculus is a glove with motors on it to simulate resistance when gripping an item, or force when something in a game moves your hand.
