Apple is apparently planning a new generation of the Apple Pencil that will be significantly more capable than previous models. The digital pen will no longer be tied to a touchscreen. Instead, it could be used on any surface—from the iPhone to a tabletop. A new patent application suggests just that.

Patents are nothing unusual at Apple. Every year, the company secures many ideas. But not all of them end up in a finished product. Nevertheless, they often reveal what Apple is working on or what technical directions the company wants to explore. In this case, it's about an Apple Pencil that works on or over any surface—without direct contact with a screen. That sounds futuristic, but it's based on fairly concrete descriptions in an officially granted patent.

An input device with optical sensors

The patent is titled "Input device with optical sensors" and describes an Apple Pencil that can function completely independently of the touchscreen of an iPad or iPhone. Instead of relying on a touch-sensitive display, all sensors would be located directly within the Apple Pencil itself. This would allow the pencil to write or draw on any surface—even in midair, similar to hover mode.

Works even without screen contact

The Apple Pencil could emit light from its tip, which would be captured by the integrated sensors. These detect so-called "spatiotemporal image brightness variations," meaning the smallest changes in the light pattern created by the movement of the pencil – even in ambient light. This is supported by a built-in accelerometer and other motion-tracking components. This allows the Pencil to detect how fast you're moving it, at what angle, and how far it is from the surface.

Drawing on any surface

Theoretically, you could sketch with the Apple Pencil on your desk while the lines are displayed on your iPad or MacBook. The movement is detected and translated digitally, similar to Wacom graphics tablets. A screen is still needed, but it doesn't have to be touch-sensitive—and you don't have to draw directly on it.

More than just a drawing tool

Interestingly, Apple lists over 20 different functions the Apple Pencil could perform in the patent. These include things like moving a cursor, opening files, adjusting volume, changing audio settings, or even making calls. So, the Pencil isn't just intended as a creative tool, but also as a general input device.

Security and access control

Apple also describes a possible use of the Apple Pencil as a security tool. Users could use the pencil to access protected areas of a computer or network. This doesn't necessarily mean that the Pencil has biometric sensors, such as a fingerprint scanner. It's more likely that authorization is handled through other means, such as Face ID, and the Apple Pencil serves only as a supplementary tool.

Possible use on many devices

Several devices appear in the patent's images: iPad, iPhone, MacBook Pro, and even the Apple Watch. An iPod is also mentioned—although this is likely meant symbolically, as current iPods are no longer available. The key point is that the new Apple Pencil could theoretically be combined with any type of display, even one that doesn't respond to touch. The stylus would provide the inputs, and the device would demonstrate the implementation.

Mechanical innovations included

The patent also mentions a mechanical variant: an Apple Pencil with a rotating ball-tip. Whether this is an alternative input method or simply an evolution of the physical tip remains unclear. Ideas for color and texture recognition have also been addressed in other patents in the context of the Apple Pencil—Apple appears to be exploring many possibilities here.

Apple Pencil of the future: How likely is its implementation?

Whether we'll ever see a product with all these features remains unclear. Apple tests many concepts, and by no means all of them make it into a finished device. But the current patent is detailed, practical, and technically sound. It shows that Apple is actively developing the Apple Pencil—away from being a mere iPad accessory and toward a versatile input tool for the entire Apple ecosystem. If, in the future, you could use the Apple Pencil to write on your iPhone, draw on your Mac, or create designs simply by moving it around your desk, that would be real progress. And that's exactly what Apple seems to have in mind. The best products for you: Our Amazon Storefront offers a wide selection of accessories, including those for HomeKit.
