A first exemplary embodiment of the present invention will be described. An example of a block diagram of an information processing device according to the present embodiment is shown in
The short distance wireless communication unit 21, by short distance wireless communication, transmits and receives other devices and a short distance radio signal. In the storage unit 22, a plurality of setting functions is registered. In the present embodiment, in the storage unit 22, as a setting function, a storage function, a camera function, a mouse function, and a key input function and the like are registered. The device control unit 23, when the short distance wireless communication unit 21 receives a short distance radio signal, selects the predetermined setting function from the storage unit 22 and sets the function relating to the selected setting function to a device of a transmission source of the short distance radio signal. In the present embodiment, the device control unit 23 makes selection of the predetermined setting function according to the type of the device of transmission source of the short distance radio signal, or makes selection based on the time when receiving a short distance radio signal, or makes selection based on information which the user set in advance.
Next, a procedure to extend the function of the information processing device 20 will be described using
As described above, the information processing device 20, when a short distance radio signal is received, sets the predetermined function to a device of transmission source of the short distance radio signal. The information processing device 20, for example, selects the predetermined setting function from the storage unit 22 based on the type of a device of transmission source of the short distance radio signal, or the time when receiving the short distance radio signal, or information which the user set or the like. The device of transmission source, by having the predetermined function to be set, functions as an external device of the information processing device 20.
As described above, by having the device of transmission source function as an external device of the information processing device 20, the information processing device 20 can use a plurality of functions provided in the device of transmission source as if it is the function which the information processing device 20 has even when it is the function which the information processing device 20 does not originally have. Accordingly, as well as effectively using a plurality of functions that the transmission source has, the convenience of the information processing device 20 improves.
Here, by registering an identification ID of the device of transmission source to the storage unit 22, only when the identification ID of the device of transmission source matches the identification ID registered in the storage unit 22, it is also possible to set the predetermined function to the device of transmission source. That is, the information processing device 20, when receiving a short distance radio signal, acquires the identification ID of the device of transmission source of the short distance radio signal by inputting directly, or receiving as a short distance wireless communication or an e-mail, or the like. Then, only when the acquired identification ID matches with the identification ID registered in the storage unit 22, the predetermined function is set to the device of transmission source. In this case, it is possible to prevent the information processing device 20 being unfairly operated by an ill-willed third party.
Further, by setting an operation unit to the information processing device 20, and when the user performs an input relating to a function extension using the operation unit after the short distance wireless communication unit 21 receives a short distance radio signal, the predetermined function can also be set to the device of transmission source. In this case, when a short distance radio signal is received from a device which is not a target of the function setting, it is possible to prevent the function being automatically set to a device which is not a target of the function setting.

Then, when it can be authenticated, monitors whether a measurement result of the electric field strength is transmitted or not. The device control unit 23A, when a measurement result is received, refers to a function setting table of the storage unit 22A, selects the setting function that is associated with the received measurement result, and sets the function relating to the selected setting function to the portable communication terminal 10 which has transmitted the short distance radio signal.
For example, the information processing device 20A, when receiving a measurement result indicating a large electric field strength, sets the function as a storage device of an external connection of the information processing device 20A to the portable communication terminal 10. Further, when receiving a measurement result indicating the electric field strength of the medium degree sets a function as a mouse, and when receiving a measurement result indicating a small electric field strength, sets a function as an external camera of the information processing device 20A.
As described above, in the present embodiment, the desired function is selected according to the measured electric field strength and is set to the portable communication terminal 10. Accordingly, based on a positional relation of the portable communication terminal 10 and the information processing device 20A, the most suitable function is set to the portable communication terminal 10
