This describes a wireless wand for a magic-themed game. The wand is held in one hand and interacts with its surroundings using a wirelessly-powered radio-frequency system. This system specifically uses short-range inductive coupling, like an RFID tag, to communicate with a compatible reader within about two feet.
Why it matters: Filed before the widespread miniaturization and cost reduction of efficient inductive power transfer and short-range RFID systems. These technologies are now more readily available and affordable for consumer-grade interactive devices.
