For example, the intelligent ring may vibrate according to a feedback signal sent by an external electrical device, so as to confirm whether the information sent by the intelligent ring is confirmed or whether the instruction is recognized. For example, after the intelligent ring sends out an instruction for controlling unlocking of the car door, if the car door is unlocked smoothly, at this moment, the vehicle control system can send a feedback signal of successful unlocking to the intelligent ring, and after the intelligent ring receives the feedback signal, the microprocessor 30 can control the intelligent ring to vibrate to feed back information of successful unlocking. For another example, the intelligent ring is in communication connection with a mobile phone, and when the mobile phone receives information or a call, the intelligent ring can be controlled to vibrate to remind a user to check the information or answer the call. If the intelligent ring is in communication connection with the doorbell, the intelligent ring can be controlled to vibrate to remind a user to open the door when someone presses the doorbell.

It will be appreciated that the vibrations generated by the smart ring may be varied as appropriate to enable the user to learn the feedback information from the vibrations. For example, the vibration may be performed briefly once when the control command is confirmed and executed by the electrical appliance, and may be performed at consecutive intervals when the control command is not recognized or not executed by the electrical appliance. Therefore, after the user sends the command, the user can know whether the command sent by the user is executed or not according to the vibration feedback, and the use is more convenient and comfortable.
