PROBLEM TO BE SOLVED: To provide a technique for suppressing power consumption required for data processing, in a device having a configuration of performing the data processing linked to walking or running of a user.SOLUTION: A walking linkage communication device (10) comprises: a pressure sensing part (120) for detecting foot pressure during walking or running of a user; a radio communication device (13) for sending data; and a control part (14) for controlling the pressure sensing part (120) and the radio communication device (13). The control part (14) controls on/off of sending of the data by the radio communication device (13) according to whether or not, an output of the pressure sensing part (120) is equal to or more than a threshold, or is equal to or less than the threshold.SELECTED DRAWING: Figure 1【課題】ユーザの歩行または走行と連動したデータ処理を行う構成を備えた装置において、上記データ処理に要する消費電力を抑制する技術を提供する。【解決手段】歩行連動通信装置(10)は、ユーザの歩行時または走行時の足圧を検知する感圧部(120)と、データの送信を行う無線通信装置(13)と、感圧部(120)および無線通信装置(13)を制御する制御部(14)とを備え、制御部(14)は、感圧部(120)の出力が閾値以上になるか否か、または閾値以下になるか否かに応じて、無線通信装置(13)によるデータの送信のオンオフを制御する。【選択図】図1
