Abstract: A discrimination device includes: a log acquisition unit that acquires sensor data including acceleration acquired by a sensor placed in a shoe, a storage unit that stores log data of the sensor data, a log calling unit that calls the log data stored in the storage unit, a discrimination unit that distinguishes a walking state from a waveform of the log data, a threshold setting unit that retains a first threshold and a second threshold, and sets the first threshold and the second threshold based on a discrimination result, and a transmission unit that transmits the discrimination result. When acceleration in the log data has not exceeded the second threshold within a discrimination time, the discrimination device outputs a discrimination result of being erroneous activation, and updates the first threshold based on a value of the acceleration in the traveling direction in the log data according to the discrimination result.
