Earlier today, a recently-published patent filing in the US provided a glimpse at how Apple could improve the experience of wearing headphones. But now two new filings have popped up which point towards the future use of ultrasound technology in its devices.
Alongside the smartphone displays, this technology could also be used to improve the accuracy of the Apple Pencil. In this case, the stylus itself would be covered in multiple sensors that would allow it to detect how the user is gripping it. It’s unclear at this point what exact benefits this would bring, although one option could allow users to switch the type of strokes or the thickness by simply modifying the grip.
As this is still only a patent, there is no guarantee that Apple will add the technology to its devices. However, when the two implementations are combined together, the overall improvements to the accuracy and usefulness of the Apple Pencil could be improved drastically.
