1.The application informs a reaction time from "beginning" to "hit" of a serve to the player by voice immediately after hitting.
2.The player can judge the adequacy of rhythmic movements(include the toss) by the length of reaction time, by comparing with the ones of succeeded serves.
3. In the case of lots of reaction times are deviated from the ones of "succeeded serve", it is much effective to hit real balls after repeated practices by using the moving image of an arm, a hand, and fingers of toss.
4. After ended a series of practices, it is computed a mean and a standard deviation.
5. These data are saved in "inner memory" of the smart phone.
6. You can see the development of serve skill at a glance, by analyzing a series of data properly.
7. The measurement of reaction time begins at the moment of "go" by the player, and ends at "hit sound."
8. On the application, it can be set freely a)the number of trials, b)the interval between trials, c)supply intervals of the balls, and d)the sensitivity of the Mic.
