MorphKeys

A reconfigurable keyboard system that lets users freely arrange individual keys in three dimensions to match their ergonomic needs and specific usage scenarios. Each key is an independent, battery-free module powered and read via near-field communication (NFC) only while being pressed, enabling wireless key input detection.
