A control method of presented information in a control device, having first and second sensor sections and that is connected to a network, is provided. The method includes acquiring information concerning a human activity detected by first and second sensor sections during first and second periods. The method also includes a first control operation of (i) determining content that is to be output by the first output section during the second period, based on the information concerning a human activity detected during the first period by the first and second sensor sections, and then (ii) causing the first output section to output the determined content in a case where it is determined that a human activity is performed during the second period in a space in which the first sensor section is disposed, based on the information concerning a human activity during the second period acquired from the first sensor section.
