Abstract
An excretion behavior recording device includes a detection section configured to detect vibration of a toilet bowl, an extraction section configured to extract a feature value included in a vibration waveform and indicating excretion behavior of each of urination and defecation of a user, a determination section configured to determine whether an occurrence cause of the vibration is the urination or the defecation based on the extracted feature value, and a recording section configured to record the determined urination and defecation.
Claims13
An excretion behavior recording device comprising:
- a detection section configured to detect a vibration waveform of a toilet bowl used by a user;
- an extraction section in communication with the detection section and configured to extract a feature value included in the vibration waveform and indicating excretion behavior of each of urination and defecation of the user;
- a determination section in communication with the extraction section and configured to determine whether an occurrence cause of the vibration waveform is the urination or the defecation based on the extracted feature value;
- and
- a recording section configured to record the determined occurrence cause of the vibration waveform being the urination or the defecation,
- wherein the detection section is attached at a position on an outer surface of the toilet bowl within a range of a height of cleaning water stored in the toilet bowl.
A life behavior display system comprising:
- a excretion behavior recording device including
- a detection section configured to detect a vibration waveform of a toilet bowl used by a user, wherein the detection section is attached at a position on an outer surface of the toilet bowl within a range of a height of cleaning water stored in the toilet bowl,
- an extraction section in communication with the detection section and configured to extract a feature value included in the vibration waveform and indicating excretion behavior of each of urination and defecation of the user,
- a determination section in communication with the extraction section and configured to determine whether an occurrence cause of the vibration waveform is the urination or the defecation based on the extracted feature value, and
- a recording section configured to record the determined occurrence cause of the vibration waveform being the urination or the defecation;
- a life behavior recording device configured to detect and record life behavior other than the excretion behavior of the user in a residence;
- and
- a display device configured to display multiple items of the life behavior including the excretion behavior of the user in a time-series graphic form.
An excretion behavior recording method comprising:
- a detection step of detecting a vibration waveform of a toilet bowl used by a user;
- an extraction step of extracting a feature value included in the vibration waveform and indicating excretion behavior of each of urination and defecation of the user;
- a determination step of determining whether an occurrence cause of the vibration waveform is the urination or the defecation based on the extracted feature value;
- and
- a recording step of recording the determined occurrence cause of the vibration waveform being the urination or the defecation,
- wherein the detection step uses a detection section attached at a position on an outer surface of the toilet bowl within a range of a height of cleaning water stored in the toilet bowl.
