Abstract

A communication terminal includes: a communication section configured to perform non-contact communication with an external apparatus; an alarming section; and a control section configured to determine a communication state of the communication section with the external apparatus, and if the communication state is determined to be a communication error state, the control section configured to cause the alarming section to give an alarm prompting a user to change a relative position of the communication terminal with the external apparatus on the basis of communication data at the time of the communication error.

Claims

1. A communication terminal comprising:

a communication section configured to perform non-contact communication with an external apparatus;

an alarming section; and

a control section configured to determine a communication state of the communication section with the external apparatus, and if the communication state is determined to be a communication error state, the control section configured to cause the alarming section to give an alarm prompting a user to change a relative position of the communication terminal with the external apparatus on the basis of communication data at the time of the communication error.

2. The communication terminal according to claim 1, wherein the communication data is packet data received from the external apparatus, and

the control section changes a displacement of the relative position in accordance with a communication error part in the packet data.

3. The communication terminal according to claim 2, wherein the control section causes the alarming section to give an alarm so as to determine the displacement of the relative position in the case of the communication error in an earlier part in a reception order from the external apparatus of the packet data to be larger than the displacement of the relative position in the case of the communication error in a later part in the reception order.

4. The communication terminal according to claim 3, further comprising a voltage measurement section configured to measure a voltage in the communication section,

wherein the packet data includes a data main body having a late order in the reception order and an additional part having an early order in the reception order and indicating a start position of the data main body, and

if the control section determines that the communication error occurs in the additional part among the data main body and the additional part, the control section causes the voltage measurement section to measure the voltage.

5. The communication terminal according to claim 4, wherein if the communication state is determined to be a communication error state, the control section causes the alarming section to give an alarm prompting the user to change the relative position after the measurement of the voltage by the voltage measurement section, and

if the voltage measured again after the alarming by the alarming section is lower than the voltage measured before the alarming, the control section causes the alarming section to alarm in a different alarming mode.

6. The communication terminal according to claim 1, wherein the control section causes the alarming section to give an alarm of movement of the communication terminal in a predetermined direction as the displacement of the relative position.

7. The communication terminal according to claim 6, further comprising

a movement detection section configured to detect the movement of the communication terminal after the alarming section gives the alarm,

wherein if the control section determines that the communication error continues after the movement detection by the movement detection section, the control section causes the alarming section to alarm movement to a different direction from the movement direction detected by the movement detection section.

8. The communication terminal according to claim 7, wherein if the control section determines that the communication error continues after the movement detection by the movement detection section, the control section causes the alarming section to alarm movement to the opposite direction to the movement direction detected by the movement detection section.

9. The communication terminal according to claim 1, wherein the alarming section is at least one of a display section displaying information, a light emitting section emitting light, a vibration section vibrating a main body of the terminal, and a sound outputting section outputting a sound.

10. A method of communication, comprising:

a communication terminal performing non-contact communication with an external apparatus;

the communication terminal determining a communication state with the external apparatus; and

if the communication state is determined to be a communication error state, causing an alarming section of the communication terminal to give an alarm prompting a user to change a relative position of the communication terminal with the external apparatus on the basis of communication data at the time of the communication error.

11. A program for causing a computer to perform processing comprising:

a communication terminal performing non-contact communication with an external apparatus;

the communication terminal determining a communication state with the external apparatus; and

if the communication state is determined to be a communication error state, causing an alarming section of the communication terminal to give an alarm prompting a user to change a relative position of the communication terminal with the external apparatus on the basis of communication data at the time of the communication error.
