Relay device for relaying data from a sensing device to a computer system

摘要

A relay device for relaying data from a sensing device to a computer system, the sensing device having an image sensor to read coded data on a first interface in order to generate first indicating data indicative of a region of the first interface, the relay device comprising: a first communications module for receiving the first indicating data from the sensing device, the first indicating data having a first format; a relay device processor for generating second indicating data using the first indicating data, the second indicationg data having a second format; and a second communications module for transmitting the second indicating data to the computer system.
