A Printed Game Controller Has Printed Buttons and Wires, but Needs Finger Sleeves
印刷するゲームコントローラ | ProtoPedia
Kazutaka Kurihara's controller prints conductive touch buttons and wiring into one 3D-printed plate. Players wear conductive finger sleeves. AI can change the layout and generate print files, including versions with 16–18 buttons.
Printing the controls together somehow added equipment to the player's fingers.
