## Abstract

In a control method, a vibration sensor of an information terminal apparatus acquires vibration data that is time-sequential data of vibrations including vibrations based upon body movements of a user on bedding on which the information terminal apparatus is placed. The acquired vibration data is stored in a memory, an action performed by the user is detected, and, from among the vibration data stored in the memory, vibration data included in a predetermined period that ends at a time at which the detected action was performed is extracted. Then, a vibration waveform indicated by the extracted vibration data is stored in the memory as a bed-leaving vibration pattern produced by the user.

## Claims

acquiring, using a vibration sensor of an information terminal apparatus, vibration data (i) that is time-sequential vibration data and (ii) that includes information on vibrations by body movements of a user on bedding on which the information terminal apparatus is placed;
storing the acquired vibration data in a memory of the information terminal apparatus;
detecting an action performed by the user; and
extracting, from among the stored vibration data, vibration data included in a predetermined period that ends at a time at which the detected action was performed, and storing a vibration waveform indicated by the extracted vibration data, in the memory as a bed-leaving vibration pattern produced by the user.

### Claim 2 (depends on 1)

The method according to claim 1, further comprising:
determining whether or not the vibration waveform indicated by the acquired vibration data conforms with the vibration pattern stored in the memory; and,
when the vibration waveform indicate by the acquired vibration data is determined to conform with the vibration pattern, transmitting, via a network, a control signal that causes operation of an electrical device that can be controlled by the information terminal apparatus.

The method according to claim 1, further comprising:
acquiring log information that includes a time at which an operation by the user was performed with respect to the electrical device,
wherein,
when the action performed by the user is to be detected, the action performed by the user is detected using the acquired log information, and,
when the vibration pattern is to be stored in the memory, the vibration pattern is stored in the memory with the time included in the acquired log information, being used as the time at which the action was performed.

### Claim 5 (depends on 1)

The method according to claim 1, further comprising:
acquiring log information that includes a time at which an operation by the user was performed with respect to the information terminal apparatus,
wherein,
when the action performed by the user is to be detected, the action performed by the user is detected using the acquired log information, and,
when the vibration pattern is to be stored in the memory, the vibration pattern is stored in the memory with the time included in the acquired log information, being used as the time at which the action was performed.

### Claim 6 (depends on 1)

The method according to claim 1, further comprising:
acquiring a detection result produced by a person-detecting sensor capable of detecting that the user is in a location that is different from on the bedding,
wherein,
when the action performed by the user is to be detected, the action performed by the user is detected using the acquired detection result, and,
when the vibration pattern is to be stored in the memory, the vibration pattern is stored in the memory with a time included in the acquired detection result, being used as the time at which the action was performed.
