Abstract

A mobile terminal device and receiver sensitivity informing method for suitably receiving an electromagnetic wave from an external reader/writer to enable a user to use service promptly and reliably. In a mobile terminal device 1 that performs communication with an external R/W 2 in a noncontact matter, when an IC card section 12 receives an electromagnetic wave from the external R/W 2, a control section 11 determines a receiver sensitivity of the device 1 corresponding to the electromagnetic wave, and an informing section 14 informs the user of a different item of content corresponding to the determined receiver sensitivity of the device 1. The informing section 14 informs the user of the content using a display 141, vibrating device 142, speaker 143, emitting device 144 or a combination thereof.

Claims

1. A mobile terminal device that performs communication with an external reader/writer in a noncontact manner, comprising:

a receiver that receives an electromagnetic wave from the reader/writer;

a determiner that determines a receiver sensitivity of the device corresponding to the electromagnetic wave; and

an informing section that informs a user of a different item of content corresponding to the receiver sensitivity of the device.

2. The mobile terminal device according to claim 1, wherein the informing section informs the content enabling a grasp of a position over the reader/writer where the receiver sensitivity of the device is the highest.

3. The mobile terminal device according to claim 2, wherein the informing section informs the content to guide the device to the position over the reader/writer where the receiver sensitivity of the device is the highest.

4. The mobile terminal device according to claim 3, wherein the informing section informs the content corresponding to a distance to the position over the reader/writer where the receiver sensitivity of the device is the highest.

5. The mobile terminal device according to claim 1, wherein the informing section has a display that displays the content corresponding to the receiver sensitivity of the device, a vibrator that vibrates corresponding to the receiver sensitivity of the device, a sound output section that outputs a sound corresponding to the receiver sensitivity of the device, an emitter that emits light corresponding to the receiver sensitivity of the device, or a combination thereof.

6. The mobile terminal device according to claim 5, further comprising:

an input section that receives an input of operation of a user,

wherein the informing section informs the content using the display, the vibrator, the sound output section, the emitter or a combination thereof, according to an instruction from the user received via the input section.

7. The mobile terminal device according to claim 1, further comprising:

a storage that stores threshold data used in determining the receiver sensitivity of the device, wherein the determiner determines the receiver sensitivity of the device based on the threshold data.

8. The mobile terminal device according to claim 7, wherein the storage stores a plurality of items of threshold data, and the determiner determines the receiver sensitivity of the device by comparison with the plurality of items of threshold data.

9. A method of informing a receiver sensitivity in a mobile terminal device that performs communication with an external reader/writer in a noncontact manner, wherein an electromagnetic wave is received from the reader/writer, a receiver sensitivity of the device is determined corresponding to the electromagnetic wave, and a user is informed of a different item of content corresponding to the receiver sensitivity of the device.

10. The method of informing a receiver sensitivity according to claim 9, wherein informed is the content enabling a grasp of a position over the reader/writer where the receiver sensitivity of the device is the highest.

11. The method of informing a receiver sensitivity according to claim 10, wherein informed is the content to guide the device to the position over the reader/writer where the receiver sensitivity of the device is the highest.

12. The method of informing a receiver sensitivity according to claim 11, wherein informed is the content corresponding to a distance to the position over the reader/writer where the receiver sensitivity of the device is the highest.

13. The method of informing a receiver sensitivity according to claim 9, wherein the content is informed using a display that displays the content corresponding to the receiver sensitivity of the device, a vibrator that vibrates corresponding to the receiver sensitivity of the device, a sound output section that outputs a sound corresponding to the receiver sensitivity of the device, an emitter that emits light corresponding to the receiver sensitivity of the device, or a combination thereof.

14. The method of informing a receiver sensitivity according to claim 13, wherein the content is informed using the display, the vibrator, the sound output section, the emitter or a combination thereof, according to an instruction received from the user.

15. The method of informing a receiver sensitivity according to claim 9, wherein threshold data used in determining the receiver sensitivity of the device is stored, and the receiver sensitivity of the device is determined based on the threshold data.

16. The method of informing a receiver sensitivity according to claim 15, wherein a plurality of items of threshold data is stored, and the receiver sensitivity of the device is determined by comparison with the plurality of items of threshold data.
