In an information processing apparatus which is connected to an external terminal having an input unit via a network, can receive an input from the input unit of the external terminal, and has its own input unit, an exclusion manager (23) monitors an input from the input unit of the external terminal and that from the self input unit. As a result of monitoring, if an input from a given input unit is generated, the exclusion manager executes exclusion control that inhibits an input from the other input unit until that input is completed.
