Although many of Apple's products are equipped with touch screens, we can only use the mouse back when facing the large screen Mac. After getting used to the human-computer interaction mode of touch, I still have the impulse to press the screen from time to time when I use iMac. The iPen 2 is a pressure sensitive stylus designed for iMac and iPad. The iPen 2 allows you to scribble freely on the iMac. You will definitely be surprised that the iMac does not have a touch screen?

You don't need to make any changes to your Mac to use iPen 2. You don't need to change your screen. Just install a device like a speaker knob on the left and right sides of the screen to allow you to scribble on the Mac screen. It's no pressure for iPen 2 to let children practice arithmetic or draw on the iMac.

Positioning handwriting through two disks

IPen 2 is an upgraded version of iPen 1. Don't think of it as an iPad. iPen 2 has a very small pen tip, which can enable you to achieve the same accuracy in different angles. If you are left-handed, it is OK. The iPen 2 is also designed to simulate the natural writing nature of a ballpoint pen, so that you can use it just like on paper.

working principle: The two knobs you stick on the screen will generate invisible light to locate your moving handwriting. A micro camera is used as a receiver to capture invisible light from the pen tip and triangulation to measure the exact position. With this new method, the signal will not attenuate even if the pen tip is at the bottom of the screen. And the iPen 2 is also available in the iPad version, but you should attach a special case to your iPad and then use it with the iPen 2.
