1. A control method of an information terminal device provided with a vibration sensor, a processor, and a memory, the control method causes the processor to execute:
first measuring, by the vibration sensor, magnitudes of a plurality of vibrations of the information terminal placed on a bedding during a first period;
determining, by the processor, whether or not there is a body movement of a user on the bedding based on whether or not the magnitude of a vibration of the information terminal device is equal to or greater than a threshold value;
acquiring, by the processor, the magnitude of the vibration of the information terminal device detected by the vibration sensor, and a vibration time indicating a time at which the vibration sensor detected the vibration of the information terminal device;
associating, by the processor, the vibration time with the magnitude of the vibration;
storing a plurality of pieces of vibration data that include the magnitude of the vibration and the associated vibration time in the memory;
acquiring, by the processor, log information including a time at which an operation by the user was performed with respect to the information terminal device;
storing the log information in the memory,
modifying, by the processor, the stored plurality of pieces of vibration data by excluding one or more pieces of first vibration data corresponding to a target vibration time period from the plurality of pieces of vibration data stored in the memory such that the modified pieces of vibration data include less data than the stored plurality of pieces of vibration data,
wherein
the target vibration time period includes an operation period in which the user performed the operation with respect to the information terminal device,
the target vibration time period includes a start time point and ending time point,
the start time point being when the user starts performing the operation with respect to the information terminal device, and
the operation period is specified based on the time in the log information stored in the memory;
updating the threshold value using the plurality of pieces of vibration data from which the one or more pieces of first vibration data are excluded;
second measuring, by the vibration sensor, magnitudes of a plurality of vibrations of the information terminal placed on the bedding during a second period; and
determining, by the processor, whether or not there is a body movement of the user on the bedding based on whether or not one or more of the magnitudes of the plurality of vibrations of the information terminal device measured during the second period is equal to or greater than the updated threshold value.
