Abstract: A distribution system is provided, the distribution system including a mobile communication terminal for detecting a gesture of a user by using a gesture detection device that is wirelessly connected, and a distribution device that can communicate with the mobile communication terminal, the distribution system including an accepting unit configured to accept registration of first acceleration data expressing a variation in acceleration within a predetermined time, and advertisement data indicating an advertisement to be displayed on the mobile communication terminal; a distributing unit configured to distribute the first acceleration data and the advertisement data to the mobile communication terminal; a comparing unit configured to compare the distributed first acceleration data with second acceleration data expressing the gesture of the user sent from the gesture detection device; and a first outputting unit configured to output the advertisement data, when the comparing unit makes the comparison.

Abstract: A gesture detection system having a gesture detection apparatus to detect a gesture of a user, and a mobile communication terminal that can communicate with the gesture detection apparatus, includes a storage unit to store first gesture data defining the gesture of the user, and audio or visual data associated with the first gesture data; an obtainment unit to obtain second gesture data representing the gesture of the user; a transmission unit to transmit the second gesture data to the mobile communication terminal; a determination unit to determine whether the gesture defined by the first gesture data is the same as the gesture represented by the second gesture data; a selection unit to select the audio or visual data associated with the first gesture data depending on the determination result; and an output unit to output the audio or visual data.
