Abstract: A measurement apparatus comprises a memory that stores instructions. The measurement apparatus comprises a processor that executes the instructions stored in the memory to: identify a propagation distance which is a length of a propagation path that a sound wave transmitted from a transmitting apparatus takes before reaching a receiving apparatus; determine, based on the identified propagation distance, a method to be used to identify a propagation time for the sound wave transmitted from the transmitting apparatus to reach the receiving apparatus from among a plurality of methods for identifying a propagation time of a sound wave; identify the propagation time for the sound wave transmitted from the transmitting apparatus to reach the receiving apparatus by the determined method; and measure an air characteristic of a location on the propagation path based on the identified propagation time and the identified propagation distance.

Abstract: Provided is a control apparatus connected to an operating apparatus and to an information processing apparatus. The operating apparatus receives an operation performed by a user. The information processing apparatus performs information processing based on an operation performed by the user at the operating apparatus. The control apparatus receives operation-related information indicating an operation performed by the user at the operating apparatus, acquires setting information regarding an operation content receivable by the operating apparatus, processes the received operation-related information according to the acquired setting information, and outputs the processed operation-related information to the information processing apparatus.
