Wireless communication device, the logical value selecting method and a logical value selection program

Measurement unit (111) measures the field intensity of radio waves received from the second device (102). Requesting unit (112) performs one of the second operation does not cause a change in the field intensity of the received radio wave that is the first operation and the measurement that produce a change in the radio wave intensity of the received radio wave to be measured requesting message requesting the second device to present to the user (104) (102) as. Selecting unit (113), whether the request unit (112) is a change in the field intensity of the received radio wave between requesting the presentation of the message to the second device (102) of any of the time limit has occurred detected, selects one of the values ​​of the logical value if the change in the field intensity of the received radio wave during the time limit has occurred, if the change in the field intensity of the received radio wave during the time limit has not occurred selecting the other values ​​of the logic value.
