Abstract

An information communication method includes transmitting a millimeter-band radio wave from a reception side, reflecting the transmitted radio wave at a transmission side while vibrating the transmitted radio wave corresponding to first information transmitted by the transmission side, and receiving the reflected radio wave at the reception side and reconstructing the first information based on a phase difference between the transmitted radio wave and the received radio wave.

Claims

1. An information communication method, comprising:

transmitting a millimeter-band radio wave from a reception side;

reflecting the transmitted radio wave at a transmission side while vibrating the transmitted radio wave corresponding to first information transmitted by the transmission side; and

receiving the reflected radio wave at the reception side and reconstructing the first information based on a phase difference between the transmitted radio wave and the received radio wave.

2. The information communication method according to claim 1,

wherein the transmission side vibrates a reflection mechanism for reflecting a millimeter-band radio wave using a speaker provided with the reflection mechanism, corresponding to the first information, to reflect the transmitted radio wave while vibrating the transmitted radio wave corresponding to the first information.

3. The information communication method according to claim 2,

wherein the transmission side outputs a signal mapped into a predetermined vibration frequency corresponding to the first information, to the speaker, and mechanically vibrates the speaker at the predetermined vibration frequency.

4. The information communication method according to claim 2,

wherein the first information transmitted by the transmission side at least includes audible information, the audible information enabling to reproduce audible sound output by the speaker.

5. The information communication method according to claim 1, further comprising:

modulating second information into a millimeter-band radio wave and transmitting the radio wave from one of the transmission side and the reception side; and

receiving the transmitted radio wave and demodulating the transmitted radio wave into the second information at another one of the transmission side and the reception side.

6. The information communication method according to claim 5,

wherein the reception side receives the radio wave for the first information using a first antenna, and

wherein the reception side transmits/receives the radio wave for the second information using the first antenna.

7. The information communication method according to claim 5,

wherein the reception side receives the radio wave for the first information using a first antenna, and

wherein the reception side transmits/receives the radio wave for the second information using a second antenna, the second antenna being different from the first antenna.

8. An information communication method, comprising:

emitting the radio wave to a reflection mechanism for reflecting a millimeter-band radio wave, and vibrating the reflection mechanism using a speaker provided with the reflection mechanism and provided to a transmission side, corresponding to first information transmitted by the transmission side, to reflect the radio wave; and

receiving the radio wave reflected by the reflection mechanism at a reception side and demodulating the first information.
