Communication method control system

A writing apparatus comprising:

• a writing unit that applies an external writing force so as to write images on a display retaining medium on which (i) the image continue to be displayed after halting application of the external writing force and (ii) the image is changed or erased according to an application of another external writing force;
• a transmission unit that employs any of communication methods, and that transmit information to a different apparatus;
• a reception unit that receives instruction information, the instruction information (i) which corresponds to identification information relating to transmitting the information to the different apparatus, (ii) which is transmitted from a control apparatus which detects the identification information and (iii) which relates to at least one of the communication methods available for the transmission unit transmitting the information;
• and
• a selector employs the received instruction information to select a communication method available for the transmission unit transmitting the information.

A control apparatus comprising:

• a storage unit that stores (i) identification information and (ii) communication method information indicating at least one of available communication methods, in association with each other,
• a detector that detects the identification information relating to a writing apparatus transmitting information to a different apparatus, the writing apparatus which applies an external writing force so as to write an image on a display retaining medium on which (i) the image continue to be displayed after halting application of the external writing force and (ii) the image is changed or erased according to an application of another external writing force;
• and
• a controller that controls to transmit, to the writing apparatus, based on the communication method information associated with the detected identification information, the instruction information relating to at least one of the communication methods available for the transmission unit transmitting the information, such that permitting the writing apparatus to select a communication method which is (i) available for the transmission unit transmit the information and (ii) one of the communication methods stored in the writing apparatus.

A computer readable medium storing a program causing a computer to execute a process for managing communication methods, the process comprising:

• applying an external writing force so as to write images on a display retaining medium on which (i) the image continue to be displayed after halting application of the external writing force and (ii) the image is changed or erased according to an application of another external writing force;
• employing any of communication methods, and that transmit information to a different apparatus;
• receiving instruction information, the instruction information (i) which corresponds to identification information relating to transmitting the information to the different apparatus, (ii) which is transmitted from a control apparatus which detects the identification information and (iii) which relates to at least one of the communication methods available for transmitting the information;
• and
• employing the received instruction information to select a communication method suitable to use for transmitting the information.
