There are two touch pens in this pillar. The top surface of the pillar is an aluminum plate, so it conducts electricity. The touch pens and the aluminum plate are connected by wiring inside, so the Anamorphicons are shown on the iPad while the user is touching the plate, it’s just as if the user is touching the iPad with two fingers. The coordinates of two points on the bottom of the pillar are obtained by an iPad application. The coordinates of the pillar and the rotation angle are obtained relative to them, and the content is provided accordingly.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
