The present invention is derived from a study conducted as part of the IT new growth engine technology development project of the Ministry of Information and Communication [Task management number: 2005-S-065-03, Task name: Wearable personal station development].

As the number of digital devices such as digital devices and user devices used indoors and outdoors increases, many remote controllers are needed to control them, and thus a remote controller for controlling digital devices as many as the number of digital devices is required. Inconvenient to the user, an integrated remote control for controlling a plurality of digital devices with a single remote control appeared.

The integrated remote controller can control each home appliance by storing control commands of each digital device and changing modes in a menu manner. When the integrated remote controller needs to control a new digital device, it needs to learn a control command, and thus requires a menu (or graphic interface).

Recently, the research of Universal Remote Console (URC) has been active as a standard research for more convenient integrated remote control, but the emphasis is on data processing itself that can control various digital devices. Consideration of how to choose is poor.

However, these technologies can be greatly affected by ambient light sources (when too bright light is nearby or too dark), and the barcodes must be changed and scanned again to reflect changes in information due to software upgrades of the digital device. shall. At present, such a technique does not consider an intuitive indicating method, and therefore does not consider a case where a plurality of barcode images are photographed.

In the remote control system of a conventional digital device operating as described above, the indoor location-based service server or remote control of the digital device using a bar code, but there are disadvantages to each, many While there are many prior art methods for selecting digital devices using infrared communication, which is used to control digital devices remotely, infrared communication makes it easy to select a remote device with a wide irradiation angle, while adjacent devices are simultaneously infrared There is a problem that can detect a command and respond at the same time, and also a device that is not aimed by the reflection can detect and respond to the command.
