1. A sensor data correction system, comprising:
a moveable mount configured to mount thereon a wearable sensor, the moveable mount configured to move with a predetermined force in a constant direction and at a constant speed; and
a computer configured to:
wirelessly receive via a network first sensor data that is sensed by a first wearable sensor mounted on the moveable mount,
wirelessly receive via the network second sensor data that is sensed by a second wearable sensor mounted on the moveable mount, and
calculate a relationship between the first sensor data and the second sensor data, and
correct the first sensor data or the second sensor data based on the calculated relationship.
