Information reception system, recording medium, and information input method

An information reception system receiving input information according to a user's operation, comprising:

• a first operation target member on which an operation surface is formed, the operation surface adjusted to produce a characteristic first melody when the operation surface is rubbed by an object;
• and
• an information reception device;
• wherein
• the information reception device, comprising:
• a storage configured to store first candidate information which serves as a candidate of the input information, the first candidate information is related with the first melody;
• an observation sensor configured to acquire observation information according to observation of sound arising in surrounding environment;
• and
• circuitry configured to:
• judge whether or not the first melody exists in the observation information acquired, and
• select, when the circuitry judges that the first melody exists, the first candidate information related with the first melody as the input information.

A non-volatile computer-readable storage medium storing computer-readable instructions that, when executed by a computer including circuitry, cause the computer to perform a method comprising:

• storing, by the circuitry, candidate information which serves as a candidate of input information, the candidate information is related with index vibration;
• acquiring, by an observation sensor, observation information according to observation of actual vibration arising in surrounding environment;
• judging, by the circuitry, whether or not the index vibration exists in the observation information acquired, and
• selecting, by the circuitry, when the circuitry judges that the index vibration exists, the candidate information related with the index vibration as the input information.
