Abstract: Present application discloses control method of controlling operation mode of washing machine by communication with washing machine. Control method includes obtaining vibration information indicative of vibration of washing tub of washing machine operating in predetermined first operation mode as operation mode; extracting predetermined feature amount having correlation with strength of floor on which washing machine is placed from vibration information; estimating strength of floor from extracted feature amount; determining whether or not operation mode needs to be changed from first operation mode based on estimated strength; and when determination is made that operation mode needs to be changed from first operation mode, outputting, to washing machine, instruction to change operation mode from first operation mode to second operation mode different from first operation mode.
