A new patent by Apple shows how it may solve its MacBook keyboard woes in future iterations of the laptops.

The display of the laptop in the patent looks like any other, but the bottom section sandwiches a touch-sensitive display between a glass keyboard and the bottom of the device.

Phone keyboards do the job just fine. However, the key thing this patent is looking for is feedback from the keys. On a smartphone, you know if you’ve hit a key because the phone will briefly flash the character you’ve tapped and also vibrate. There’s very little feedback from just hitting the screen.

Much of the patent is made up of possible designs for how the key would move when force is applied.
A final set of considerations are made regarding enhanced feedback for key presses. Other than the act of pushing down on the key, the patent leaves room for the possibility of haptic feedback (smartphone-like vibrations for each tap), or "resilient members,’" either spring or collapsible dome structures within the key that make them harder to press, giving the user a similar feeling to typing on a normal keyboard.

There have also been complaints about the space bar entering two spaces instead of one.
Your skeptic hat must be firmly on while looking at these designs; there’s no guarantee this will become part of any Apple product soon, or even ever. The whole glass keyboard layer does seem at this point in time an ambitious thing to actually make, but existing large dual screen and touch screen devices, like Lenovo’s Yoga Book, are asking questions about keeping the traditional physical keyboard.
Even if Apple’s design doesn’t pan out, it’s still a strong suggestion that the days of the keyboard as we know it are numbered.
