A method of enabling interaction with a printed schedule document using a mobile device including sensing means, processing means and a transceiver, the schedule document including human-readable first schedule information and machine-readable coded data, the method including the steps of: (a) sensing at least some of the coded data with the sensing means while the mobile telecommunications device is used by a user to physically interact with the schedule document; (b) decoding, with the processing means, at least some of the sensed coded data and generating indicating data on the basis of the decoded coded data; (c) transmitting, using the transceiver, the indicating data to a remote computer system via the wireless telecommunications network; (d) receiving, using the transceiver, response data from the computer system, the response data having been sent in reply to the indicating data; (e) generating, using the processing means, a layout based on the response data, the response data representing further schedule information; and (f) outputting the layout in a human-readable form.
