Apple is continuously dominating the market with the leap of their breathtaking gadgets Apple Pencil 2nd Generation as an example.
Have you ever wondered how Apple pencil works? What’s the technology behind its working?
Indeed, the Apple pencil delivers undoubtedly precision and industry-leading low latency, making it an excellent companion for drawing, sketching, coloring, taking notes, etc.
What is not imagined, can be drawn through Apple Pencil 2nd Generation when used with iPad Pro 12.9-inch (6th generation) and iPad Pro 11-inch (4th generation).
Let’s understand a bit about the technology working behind the Apple Pencil – that delivers precision, at every moment.Also read: Best 10 Email Marketing Tools in 2021

Apple Pencil is an innovative wireless stylus pen that infers low-latency touches and reacts quickly on the surface (iPad tablets) used for taking notes, marking up PDFs, sketching, coloring, and drawing.
When it is in hand, it feels easy and natural to use as a pencil.
Though it’s not made up of Wood and Graphite, it uses an ultra-low-power STM32L151UCY6 device featuring Arm Cortex-M3 MCU running at 32 MHz with 64 KB of flash memory.
Besides this, the Apple Pencil also uses a magnetic entity, meaning it has a magnetic top with a magnetic cap that helps to stick at both corners next to the force touch trackpad and speakers.
You can call it the ‘Magnetism of Apple Pencil’
Most people don’t know how the apple pencil works exactly. The Apple Pencil reads and functions based on the three following data(s):
👉 Pen tracking aka path
👉 Force measurement aka pressure sensitivity
👉 Orientation measurement aka tilt sensitivity
And we will learn each of them in detail.
Tracking of Stylus or pen tracking is the first primitive data indulged in the functioning of the Apple Pencil. This refers to tracing the movement of the Apple Pencil.
You would be flaunted to know that the tracking of the pen over the surface works by auditing the location of the Apple Pencil about 240 times in a second.
This scan helps ensure more accurate pen tracking information. That means the occurrence of tracking pass-over is very, very less.
Another reason for the accurate tracing of the stylus could be the surface of the iPad is meaningfully designed to accept both the stylus and hand input. This exception is absent in other Apple devices such as iPhones or Macs, making it incompatible with the Apple Pencil.
Measuring the hand force or calculating pressure sensitivity is the second important data required for the Stylus.
To do this, the stylus incubates a hyper-robust force sensor that calculates pressure information (varying as hard as you press the stylus) to result in a more mesmerizing drawing experience.
The calculation of force applied on the stylus is trickier than it appears. The force sensor resides above the stylus point, measures the pressure applied on the surface, and data is then processed and sent wirelessly to the tablet.
The force sensor is responsible for analyzing the variation of pressure i.e. three-dimensional force calculation; Axial force, Radical force, and Normal.
Certainly, this allows the stylus to measure the accurate force plus an exact angle to deliver a precise experience while writing or sketching.
For calculating and reading angle, there’s another sensor used. Read more in the next heading.
Tilt detection or orientation measurement is the final data to interpret in the working of the Apple Pencil.
So, how does tilt sensitivity work?
To calculate tilt shifting movement, the stylus uses tilt sensitivity and measures the orientation of the stylus relative to the surface.
Thanks to the industry-leading low latency, the stylus can study and react quickly to the tilt data, resulting in using the stylus with varying angles.
Besides this, there is more complex data used for the calculation of the angle of the tip.
Before going into the details, the Apple Pencil consists of two electrodes. Firstly, on the tip called tip electrodes, and second above it called ring electrodes.
These two electrodes are responsible for natural pencil-like behavior. Whatever, here are the working steps:
Capacitance is the ability of the material or device to store electric charge. Concerning capacitance, the tablet picks the stylus’s electrodes and then correlates the capacitances to measure the orientation of the Apple Pencil.Also read: 7 Best Instagram Font Generators (Apps & Websites)
From the above scripts, we learned that the Apple Pencil has pressure sensitivity and angle detection with super accurate low-latency response that enables smooth marking on the screen.
It incubates global-tech leading STMicroelectronics STM32L151UCY6 Ultra-low-power 32-bit RISC ARM-based Cortex-M3 chip powering at 32 MHz with 64 KB of flash memory.
