Holding manner determination device, control program, and recording medium

A holding manner determination device, comprising:

• a detection data acquisition circuitry that acquires detection data which is distribution data of sensor values detected by a plurality of touch sensors of an information terminal;
• a coincidence calculation circuitry that calculates a coincidence between reference data, which is the distribution data associated with a pre-assumed manner of holding the information terminal, and the detection data;
• and
• a holding manner determination circuitry that determines a manner of holding the information terminal on the basis of the coincidence calculated by the coincidence calculation circuitry.
