Estimation device, information presentation system, estimation method, and recording medium

A method for estimating a future status related to a long-term care need of a user, the method comprising:

• acquiring sensor data measured according to walking of the user by a measurement device disposed on footwear of the user;
• generating time-series data based on the acquired sensor data and calculating, for each of a plurality of gait cycles of the user, a walking speed of the user based on the time-series data;
• calculating, as a numerical value related to a distribution of the walking speeds, at least one of a mean value and a standard deviation of the walking speeds over the plurality of gait cycles;
• acquiring physical data of the user including at least an age of the user;
• inputting the numerical value related to the distribution of the walking speeds and the physical data of the user to an estimation model that outputs care-related information including at least one of a degree of required care, a degree of required support, and a reference time related to recognition of required care, in response to inputs of the numerical value related to the distribution of walking speeds and the physical data of the user, to obtain the care-related information;
• and
• generating output data representing at least one of the degree of required care, the degree of required support, and the reference time related to recognition of required care included in the obtained care-related information.

A non-transitory computer-readable recording medium storing instructions that, when executed by a processor, cause the processor to perform a method for estimating a future status related to a long-term care need of a user, the method comprising:

• acquiring sensor data measured according to walking of the user by a measurement device disposed on footwear of the user;
• generating time-series data based on the acquired sensor data and calculating, for each of a plurality of gait cycles of the user, a walking speed of the user based on the time-series data;
• calculating, as a numerical value related to a distribution of the walking speeds, at least one of a mean value and a standard deviation of the walking speeds over the plurality of gait cycles;
• acquiring physical data of the user including at least an age of the user;
• inputting the numerical value related to the distribution of the walking speeds and the physical data of the user to an estimation model that outputs care-related information including at least one of a degree of required care, a degree of required support, and a reference time related to recognition of required care, in response to inputs of the numerical value related to the distribution of walking speeds and the physical data of the user, to obtain the care-related information;
• and
• generating output data representing at least one of the degree of required care, the degree of required support, and the reference time related to recognition of required care included in the obtained care-related information.
