This paper is the second report on Touch Volley after Vol. 6 No. 1 of Journal of Volleyball Sciences.
This paper describes the outline of Touch Volley, an evaluation of the progress of each user's data input manipulation to this system and a Video Link.
Touch Volley is a volleyball tactical support system. Each computer implements a touch sensor function in the display. The developed system consists of 3 functions: Data Input. Tactical Support and Data Analysis. In the Data Input function, the user inputs game data by touching display directly. If 2 laptop personal computers are connected by LAN, the user can use the Tactical Support function during the game. This function receives a game data from Data Input function of the other laptop PC. After the game, the user can analyze details of the game data through the Data Analysis function. After the game, the user can pick up some of the plays and compare them, and the cause of the poor plays can be found.
We evaluated the system itself through the actual game to check the usability and reliability of each user's data input manipulation. From the experimental results, several trials are needed for the full command of the system.
We have incorporated Video System into Touch Volley. The Video System can record volleyball games and playback the video by referring to the analysis results. On inputting the Data, the user can choose the Recording Video function from the function list. Starting of the video recording is synchronized with that of the data input. The scene of scoring and spiking (or serving) by the player can be searched by the analysis results. The Video System makes the player aware of their good and bad points immediately.
