Behavior visualization device and behavior visualization method

A behavior visualization device comprising:

• processing circuitry performing a process of:
• setting a summary condition for extracting whereabouts deeply associated with a target of interest;
• extracting whereabouts deeply associated with the target of interest in each of a plurality of time zones on a basis of sensor information or device information indicating a change in state of a sensor or a device installed within a range to be whereabouts of the target of interest and the summary condition;
• calculating areas of figure regions of figures representing whereabouts deeply associated with the target of interest, and a distance between the figure regions, and generating drawing figure data for displaying a figure representing whereabouts deeply associated with the target of interest in a hierarchical structure;
• and
• displaying drawing figure data on a display device, wherein
• the process includes:
• estimating a degree of behavior indicating how much the target of interest is performing behavior in each whereabouts for each of the time zones on a basis of information defining a region to be whereabouts of the target of interest, information defining a place where the sensor and the device are installed, the sensor information, the device information, and the summary condition, extracting whereabouts having the highest degree of behavior as summary whereabouts for each of the time zones, and extracting whereabouts having the second highest degree of behavior after the summary whereabouts as associated whereabouts;
• and
• estimating, on a basis of the degree of behavior between two whereabouts included in the summary whereabouts and the associated whereabouts, a degree of association between the two whereabouts for each of the time zones, and
• the process generates drawing figure data for displaying a figure representing the summary whereabouts for each of the time zones on a time axis as a parent node on a basis of the degree of behavior and the degree of association, and displaying a figure representing the associated whereabouts below the figure representing the summary whereabouts in a hierarchical structure.

A behavior visualization method comprising:

• setting a summary condition for extracting whereabouts deeply associated with a target of interest;
• extracting whereabouts deeply associated with the target of interest in each of a plurality of time zones on a basis of whereabouts information indicating whereabouts of the target of interest and the summary condition;
• calculating areas of figure regions of figures representing whereabouts deeply associated with the target of interest and a distance between the figure regions, and generates drawing figure data for displaying a figure representing whereabouts deeply associated with the target of interest in a hierarchical structure;
• and
• displaying drawing figure data on a display device, wherein
• the step of extracting whereabouts deeply associated with the target of interest includes:
• calculating an accumulated value of time during which the target of interest exists in each whereabouts for each of the time zones on a basis of the whereabouts information and the summary condition, extracting whereabouts having the largest accumulated value in each of the time zones as summary whereabouts, and extracting whereabouts having the second largest accumulated value after the summary whereabouts as associated whereabouts;
• and
• calculating a movement frequency between the summary whereabouts and other whereabouts by the target of interest for each of the time zones and extracting whereabouts having a high movement frequency with respect to the summary whereabouts as the associated whereabouts on a basis of the summary condition, and
• the step of generating the drawing figure data includes,
• generating drawing figure data for displaying a figure representing the summary whereabouts for each of the time zones on a time axis as a parent node on a basis of information regarding an accumulated value of time during which the target of interest exists in each whereabouts for each of the time zones and information regarding a movement frequency between the summary whereabouts and other whereabouts by the target of interest, and displaying a figure representing the associated whereabouts below the figure representing the summary whereabouts in a hierarchical structure.
