I predict that the next generation of touchscreens will be screens whose surface can programmatically change on a physical level, such that you can physically feel a screen button (your finger noticeably presses against it while sliding), and when pressed, it gives the sensation that the button has been pressed.
Currently, engineering solutions for this are expensive (or not as cheap as necessary), but they exist. Next up are miniaturization, cost reduction, and scaling.
