- The patent shows how lasers could monitor a display for touch inputs.
- It would increase the accuracy of iOS keyboards, and could even allow for touch-typing.
An Apple patent published today has revealed how the laser technology at the heart of Face ID could also be used to track touch inputs on a display so as to revolutionize typing on a touch-screen display.
As reported by AppleInsider, the patent is titled "Self-Mixing Interference Based Sensors for Characterizing Touch Input", and is focused around VCSEL (vertical-cabity surface-emitting lasers). These lasers could be housed in a display. By emmitting light, they could measure a display surface to track touch inputs, improving the accuracy of what's recorded. According to the report:
By measuring deflection, the system could determine not only where you are pressing, but how much pressure is being applied, similar to 3D touch. As AppleInsider notes, this feature could be engineered to ignore touches below a certain level of pressure. This could mean that a user might be able to rest their fingers on the touch screen without triggering an input, to allow for touch-typing.
Of course, filing a patent doesn't guarantee that this tech will ever feature in an iOS device of the future. However, this patent certainly is among the less outlandish and more applicable patents we've seen.

Touch keyboards "advancements" are like someone trying to solve a problem that's already been solved. It's called a physical keyboard, it has the best accuracy which you won't be able to beat with any touchscreen keyboard and you can also type without looking. Autocorrect, lasers, swipe keyboards, key prediction, suggestions… You don't need any of these band aids if you just have a physical keyboard
Agreed, the writing is on the wall for completely useless on-screen keyboards. Apple needs to bring back the physical keyboard on the iPhone 12! /s
Even with the sarcasm, there's a market for people who want physical keyboards, and plenty of people use them on the iPad where you already have far better accuracy on the touchscreen thanks to the size of the screen. BlackBerry is still releasing phones with physical keyboards, and a company called F(x)tec has been working on a phone with a slide-out physical keyboard which has gained a lot of popularity (https://www.fxtec.com/pro1/).
