A matching processing unit (312) calculates a coincidence between distribution data of sensor values detected by a touch panel (10) and holding hand reference data (Ref1), and a holding hand determination unit (314) determines a holding hand on the basis of holding hand information of the holding hand reference data (Ref1) whose coincidence with detection data is equal to or greater than a threshold. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The holding manner determination device according to claim 1, further comprising an erroneous touch determination circuitry that determines a position of an erroneous touch on the basis of the reference data, wherein erroneous touch information indicating the position of the erroneous touch when the information terminal is held with the pre-assumed specific holding manner is added to the reference data. ### Claim 3 (depends on 1) The holding manner determination device according to claim 1, wherein the distribution data generated when a user actually holds the information terminal with the specific holding manner is stored in a storage of the information terminal as the reference data. ### Claim 4 (depends on 3) The holding manner determination device according to claim 3, further comprising a reference data deletion circuitry that, in a case where as a result of calculating coincidences between the reference data and the predetermined number of pieces of detection data by the coincidence calculation circuitry, the number of times that a coincidence equal to or greater than a threshold is obtained does not exceed a reference value, deletes the reference data from the storage. ### Claim 5 (depends on 3) The holding manner determination device according to claim 3, further comprising a reference data addition circuitry that, in a case where coincidences between the detection data and respective pieces of the reference data that have been already stored in the storage are all lower than a predetermined value, causes the storage to store the detection data as new reference data corresponding to the holding manner determined by the holding manner determination circuitry. ### Claim 6 (depends on 1) The holding manner determination device according to claim 1, further comprising a holding manner information output circuitry that outputs, to a control device that executes an application in the information terminal, a determination result which is determined by the holding manner determination circuitry and which indicates the manner of holding the information terminal. ### Claim 7 (depends on 2) The holding manner determination device according to claim 2, further comprising an erroneous touch information output circuitry that outputs, to a control device that executes an application in the information terminal, a determination result which is determined by the erroneous touch determination circuitry and which indicates the position of the erroneous touch. ### Claim 8 (depends on 1) The holding manner determination device according to claim 1, further comprising a reference data selection circuitry that selects, from pieces of reference data stored in a storage device that is able to be used by the holding manner determination device, the reference data that is used when the coincidence calculation circuitry calculates the coincidence between the reference data and the detection data, on the basis of user information acquired in advance by the information terminal. ### Claim 9 (depends on 8) The holding manner determination device according to claim 8, wherein the storage device that is able to be used is an external storage device of the information terminal. ### Claim 10 (depends on 1) A non-transitory computer-readable recording medium having a control program that causes a computer to function as the holding manner determination device according to claim 1 and that causes the computer to function as each of the circuitries. ### Claim 11 (canceled)
