For operation, after adjusting time and cooking mode as using ordinary stoves, the users can do whatever they want with wearing the ring. There is no need to stay all the time in the kitchen due to worries about forgetting time. When the food reaches the configured temperature or time, the chip of the induction cooker will sense the temperature change inside the cooker and send a wireless signal to the ring. The temperature of the internal heating strip of the ring will rise to 40 °C rapidly, giving the users a slightly hot feeling. Then the users can adjust the power of the cooker remotely by rotating the ring or simply turn off the cooker.
