摘要： In an information processing apparatus, a display control part 31 causes a display part to display one or more human models in which parameters relating to shapes and sizes are set. A model selection reception part receives, from a user, a selection operation for selecting one human model from the one or more human models. A parameter changing part 34 changes the parameters set for the human model in conjunction with a change operation from the user for the selected human model.
