  • step S210 for example, after the significant movement of the smart glass wearer 10, which is performed in step S210, it is determined whether or not a channel change signal is received (S220). Accordingly, after determining the presence of the significant movement in step S210, when a channel change signal is received within a predetermined short period of time (T) (S220), the controller 110 may finally determine the channel change, which is performed by the smart glass wearer 10 (S230).
