Methods and systems are provided for capturing written information from an information field of a document using a computer system. Whereas the power supply unit and the control electronics are in permanent operation when conventional devices are in the standby mode and consequently have a high power consumption, the invention proposes a solution for saving energy while retaining convenience of operation by which the power supply unit is switched off in the standby mode. Upon a triggering of the bonus event, any player eligible to participate in the bonus may achieve an outcome generated from the bonus event including the shared display. Each identified object may be scored by the social-networking system based at least in part on a connectivity of the corresponding external node to the one or more internal nodes.
