Spin Coach: A Baseball Training Software for Identifying Spin-Induced Deflections, Study notes of Engineering

University of Arizona (UA)Engineering

A part of the product documentation for spin coach, a baseball training software designed to help users identify the spin of a baseball and predict the resulting deflection. Information on document mappings, systems requirements, risk analysis, project schedule, and user manual. The software is intended for both professional baseball players and casual players, and includes features like classroom mode for learning about pitch types and their deflections, batting practice mode for applying this knowledge in an un-timed setting, and game mode for practicing identification of spin-induced deflections under time pressure.

Wood Product Documents SIE 554A, Fall 2006 Classroom: The Classroom mode allows the user to learn how pitch type affects the spin and the subsequent movement of the ball. You may choose to learn about spin induced deflections by selecting the Textbook or Display Spin Type icons. The Textbook contains basic background information about pitch type, levels in the game, and instructions for playing the game, or Display Spin Type allows you to view a spinning four-seam fastball, two- seam fastball, curveball, or slider and see the expected spin-induced deflection of the ball from the pitcher. Batting Practice: The Batting Practice mode allows the user to apply the information learned in the practice mode in an un-timed setting. A random sequence of pitch types will be displayed and the user must select the area on the screen corresponding to the appropriate spin-induced deflection.

  1. Select Begin Practice.
  2. Wait for the bell to sound to alert you that a pitch is about to come.
  3. A random pitch type will be displayed until you select the appropriate box on the screen corresponding to the appropriate spin-induced deflection.
  4. Use the keyboard number keys or mouse to select the area in the strike displayed on the screen that you expect the ball to go.
  5. You will be notified if you have hit or missed the pitch and advice on how to better predict the deflection of the ball. Game: The Game mode allows the user to practice identification of the spin- induced deflection after a defined display duration and response window (see Textbook for more information on selecting the appropriate level of play).
  6. Select Begin Game.
  7. Wait for the bell to sound to alert you that a pitch is about to come.
  8. A random pitch type will be displayed for the display duration corresponding to the level chosen.
  9. As soon as the ball disappears, notifying you of the start of the response window, use the keyboard number keys or mouse to select the area in the strike displayed on the screen that you expect the ball to go.
  10. You will be notified if you have hit or missed the pitch and advice on how to better predict the deflection of the ball.
  11. After each pitch, statistics displayed on the screen will updated. This allows to identify total pitches missed, pitched missed due to incorrect
