Fecha de publicación: 18/08/2011 Fuente: Wipo "digitalization" A method for pairing a control device with a digital sign is provided. The method includes receiving control device geometric attributes and digital sign geometric attributes, determining a digital sign identification based on the control device geometric attributes and the digital sign geometric attributes, and transmitting the digital sign identification to the control device. The control device geometric attributes may define geometric attributes of the control device. The digital sign geometric attributes may define geometric attributes of the digital sign that the control device is attempting to control. The digital sign identification may define the digital sign that the control device.
