Embodiments of the application provide information processing systems, methods and devices based on Internet of Things. An information processing system comprises a server device, a first device and a second device. The first device and second device are both an Internet of Things device. The first device is configured to: in response to detecting that a first acquisition instruction is triggered, acquire biometric feature information, and send the acquired biometric feature information to the server device. The server device is configured to identify a user corresponding to the biometric feature information. The second device is configured to: in response to detecting that a second acquisition instruction is triggered, acquire body movement information associated with the user, and send the acquired body movement information to the server device. The server device is further configured to perform an operation for the user according to the body movement information.
