The concept exploration for the spin coach product during the sie 554a, fall 2006 semester. The team, consisting of blake, wolert, montealegre, and wood, developed several concepts for an interactive baseball training system. These concepts include an instructional dvd, an interactive batting cage, cd-rom interactive training, special magnifying glasses, and sonar head gear. Each concept aims to improve the player's ability to assess pitches and make appropriate adjustments to achieve optimal ball deflection.

Wood Product Documents SIE 554A, Fall 2006 3 12/05/2006 J. Wolert Editorial updates. 5.1 System Design Concepts 5.1.1 Concept 1 – Instructional DVD An instructional DVD can be used to teach a player to how to assess a pitch and make appropriate adjustments to the bat to achieve desired deflection of the ball via instructional modules in DVD format. Upon start up of the DVD a main menu would appear that displays the module choices. The training modules can focus on the following areas: laboratory demonstrations of ball spin on a drill bit (from Bahill); live pitching examples, including slow motion replays that focus in on areas of interest (pitcher’s grip, ball spin, ball trajectory); live hitting examples that discuss how each pitch should be hit to result in desired deflection of the ball; a quiz section that uses live and laboratory examples to assess the users understanding of the concepts. 5.1.2 Concept 2 – Interactive Batting Cage A batting cage and pitching machine can be outfitted with additional hardware (computer) with a software interface that uses interactive technology to teach the player to recognize the pitch and react accordingly. The instruction would not only academic, but add the physical interact to put instruction into practical application. A commercial off-the-shelf computer can be modified so that it can interact with a pitching machine. Electrical connections will allow message traffic between the computer and the pitching machine. The computer software would allow the player to choose the mode in which they would like to operate: Stand Alone (Classic Instruction), Classic Quiz, Interactive Learning, Go Mode. Stand Alone (Classic Instruction) Mode would consist of traditional computer learning tools that are similar to video instruction. It would have modules that focus on laboratory demonstrations of ball spin on a drill bit (from Bahill); live pitching examples, including slow motion replays that focus in on areas of interest (pitcher’s grip, ball spin, ball trajectory); live hitting examples that discuss how each pitch should be hit to result in desired deflection of the ball. Classic Quiz Mode would consist of interactive quizzes that use live and laboratory examples to assess the users understanding of the concepts. The quizzes would be interactive and adaptive to the answers given by the user. Feedback and further instruction on a concept would be given upon receipt of an incorrect answer. Interactive Learning Mode would be the mode where instructions are put into practice. In this mode the player could choose from several physically interactive modules: pitch recognition where the software drives the pitching machine to randomly send pitches and audibly announces what type of pitch is sent and

Thus, it would allow the player to better discriminate the different types of pitches, especially spins on the ball. This insight would allow the batter to better position himself for optimal deflection once the ball is hit. This system would also contain a variable magnification option. An additional 100X magnification would provide the player with an understanding of the pitcher’s grip type prior to ball release. With this option and an included reference manual, the player would be able to learn the relationship that exist between the grip types, spin on the ball, and hit ball deflection. See figure below.
Wood Product Documents SIE 554A, Fall 2006 5.1.5 Concept 5 – Sonar Head Gear This system would use a technology that mimic’s what is found in nature. Dolphins use their sonar to identify objects of different sizes and shapes. With this system, the player would wear a head gear that transmits sound waves ranging from 1 – 120 kHz to the ball; these sounds waves will be then transmitted back to the head gear. Depending on the spin of the ball, the player would hear different types of sound pitches and adjust accordingly to optimize the deflection of the ball once hit. See figure below.
Wood Product Documents SIE 554A, Fall 2006 would alert the batter on the incoming spin type. The player would then adjust accordingly to optimize the deflection of the ball once hit. See figure below. 5.1.7 Concept 7 – Do Nothing Alternative The player can relay on his knowledge of batting against each type of pitch, using traditional training (repetition, coaches, etc). 5.2 Evaluation Criteria Most of the below of figures of merit were develop from input provided by the customer, Dr. Terry Bahill. His written documents and personal interviews identify that the following systems measurements would provide indication of the degree fulfillment to some customer requirements. 5.2.1 I/O PERFORMANCE REQUIREMENTS
Wood Product Documents SIE 554A, Fall 2006 5.2.1.1 Convenience The measurement of convenience stems from a combination of portability, ease of use, and accessibility. The scoring for this measurement follows a Monotonic Increasing Function with a baseline of 5 and U/L thresholds of 10 and 0. This measurement is unit less. 5.2.1.2 Effectiveness The measurement of effectiveness determines the percent increase on the user’s batting average over time. The scoring for this measurement follows a Monotonic Increasing Function with a baseline of 20% and U/L thresholds of ∞ and 0. The unit of measure is in percent. 5.2.1.3 Sensory Perception The measurement of sensory perception relates to the easiness of identifying the different pitch types either via a sound, display, touch or other. The scoring for this measurement follows a Monotonic Increasing Function with a baseline of 5 and U/L thresholds of 10 and 1. This measurement is unit less. 5.2.1.4 Duration Control The measurement of duration control relates for the ability of the player to control the display duration of the image presentation. The scoring for this function follows the below Boolean outputs: 0 = the player cannot control duration of the image presentation. 1 = the player can control the duration of the image presentation 5.2.1.5 Verification The measurement of verification relates to ability for the system to store the player’s progress and stats. The complexity and the presentation of the amount of information being stored would be the basis for this rating. The scoring for this measurement follows a Monotonic Increasing Function with a baseline of 5 and U/L thresholds of 10 and 0. This measurement is unit less.
Wood Product Documents SIE 554A, Fall 2006 follows a Monotonic Decreasing Function with a baseline of 6 U/L thresholds of 12 and 0. This measurement is in months. 5.2.3.2 Upgrade Ability This measurement relates to the ability for the system to be upgraded to handle more sophisticated pitching scenarios or demands by baseball and softball players. The scoring for this measurement follows a Monotonic Increasing Function with a baseline of .5 and U/L thresholds of 1 and 0. This measurement is in percent. This measurement is unit less. 5.2.3.3 Time to Train This measurement relates to how easy is to train the baseball or softball players on how to use the system. The scoring for this measurement follows a Monotonic Decreasing Function with a baseline of 3 U/L thresholds of 7 and 0. This measurement is in days. 5.3 Figures of Merit The figures of merit are calculated using the test plan described in Document 3 and based on the systems described in Documents 6.
