Device control method and system thereof

A system, comprising:

• a plurality of electronic devices configured to establish a communication network;
• a portable device having image capturing function, being connected to the communication network and communicable with the electronic devices, wherein the portable device is operable to;
• capture a first image of a specific area, wherein the first image containing a number of electronic devices connected to the communication network within the specific area;
• and
• execute a device recognition and control procedure, comprising:
• a). transmitting a connection signal through the communication network to the selected one electronic device on a device list, wherein the device list containing all electronic devices connected to the communication network;
• b). determining whether a selected electronic device is appeared in the first image captured based on whether a response from the selected electronic device has be received within a preset period;
• c). identifying the selected electronic device on the device list and the relative position of the selected electronic device with respect to another electric device in the first image captured upon determining that the selected electronic device is in the first image;
• and
• d). transmitting, by the portable device, the connection signal to another electronic device on the device list and repeating, processes b) and c) until all the connected electronic devices on the device list are verified, to identify the relative positions of all electronic devices contained in the first image.

A non-transitory compute readable medium having instructions which when executed by a processor of a portable device with image capturing function perform a method comprising:

• causing the portable device to capture a first image of a specific area, wherein the first image containing a number of electronic devices connected to a communication network within the specific area;
• and
• causing the portable device to execute a device recognition and control procedure, comprising:
• a). transmitting a connection signal through the communication network to a selected electronic device on a device list, wherein the device list containing all electronic devices connected to the communication network;
• b). determining whether the selected electronic device is in the first image captured based on whether a response from the selected electronic device has been received within a preset period;
• c). identifying the selected electronic device on the device list and the relative position of the selected electronic device with respect to another electric device in the image captured upon determining that the selected electronic device is in the image;
• and
• d). transmitting, by the portable device, the connection signal to another electronic device on the device list and repeating, processes b) and c) until all the connected electronic devices on the device list are verified, to identify the relative positions of all electronic devices contained in the first image.
