Control method, controlled device, user interaction device and computer program product
First Claim
1. A method for controlling a controlled device, wherein the controlled device comprises an RFID tag and a host controller, wherein the RFID tag is connected to the host controller via a wired host connection, the method comprising the following steps:
- (s1) the host controller writes operational parameters to the RFID tag through the host connection;
(s2) a user interaction device reads the operational parameters from the RFID tag through an RFID connection;
(s3) a user changes the operational parameters via a user interface comprised in the user interaction device;
(s4) the user interaction device writes the operational parameters to the RFID tag through the RFID connection;
(s5) the host controller reads the operational parameters from the RFID tag through the host connection and adapts the behavior of the controlled device by configuring a set of controlled functions based on the operational parameter;
wherein the RFID tag sends a wake-up signal to the controlled device upon a predetermined event, such that the controlled device wakes up from an off state or low-power state;
wherein a handshake protocol is executed between the user interaction device and the controlled device via the RFID tag, such that the controlled device may return to the off state or low-power state if it does not need to perform a step of the method;
wherein the handshake protocol comprises that the user interaction device changes a signaling flag comprised in the RFID tag;
wherein the signaling flag indicates whether or not the controlled device needs to perform a specific step of the method;
wherein, upon waking up, the controlled device reads the signaling flag and returns to the off state or low-power state if the signaling flag indicates that it does not need to perform any specific step of the method.
