Information processing apparatus and information processing method

An information processing method executed by a system including a computer, a mat having position markers, and an imaging device configured to capture images of a user's foot positioned on the mat, the method comprising:

• a determination step of determining three-dimensional foot measurements based on the position markers in the captured images to generate measurement information;
• an acquisition step of acquiring the measurement information at a first timing taken by measuring a foot size of the user;
• a purchase tendency determination step of determining a purchase tendency of the user by comparing sizes of footwear previously proposed to the user with sizes of footwear actually purchased by the user;
• an estimation step of estimating a first period taken until the foot size of the user meets a predetermined condition based on the measurement information at the first timing acquired by the acquisition step and a foot development pattern based on an attribute of the user at the first timing to determine an estimation result;
• an adjustment step of adjusting the estimation of the first period based on the determined purchase tendency;
• and
• a provision step of providing information for proposing footwear in a size suitable for foot development of the user based on the estimation result.
