MorphKeys: A Reconfigurable Keyboard System Using Switched NFC Tags
summary
A working prototype implements battery-free NFC keys that become active only while pressed, a reader with relay resonators to extend range, and a molded iron-sand clay base for magnetic, 3D fixation without eddy-current interference. The system detects keys reliably across 32–55 mm at center-to-edge, still reads tilted keys at 30° to about 20 mm, and reports roughly 26 ms single-key latency with linear increases under NFC anti-collision for simultaneous presses.
