Wood Product Documents SIE 554A, Fall 2006 2.1 Deficiency A system does not currently exist to teach a baseball players to identify the spin of a ball in order to spin-induced deflection. 2.2 Inputs/Outputs The inputs to the system will be video from Bahill’s lab (1), video of spinning baseballs (2), and player input (3). The output from the system will be education material, likely in video format (1). 2.3 Functional Requirements 2.3.1 The system shall gather and store Player’s preferences for the session (CR-1). 2.3.2 The system shall gather and store Player’s cumulative information in a player data table (CR-2). 2.3.3. The system shall compute random numbers (CR-3). 2.3.4 The system shall alert Player that a pitch is about to come (CR-4). 2.3.5 The system shall present video images of various pitches on a display (CR 5). 2.3.6 The system shall accept Player predictions about the direction of spin- induced deflections using a numeric keypad (C-R6). 2.3.7 The system shall provide feedback to Player (CR-7). 2.3.8 The system shall store Player predictions in a response data table (CR-8). 2.3.9 The system shall be able to count from 0 to ten (CR-9). 2.3.10 The system shall store Player’s session in a response table (CR-10). 2.3.11 The system shall have a BST (CR-11). 2.3.12 The system shall be capable of timing display duration (CR-12). 2.3.13. The system shall use SI units (CR-13). 2.3.14. The system shall be capable of timing the response window (CR-14). 2.3.15. The system shall teach spin induced motion of various pitches (CR-15). 2.4 Technology Requirements 2.4.1 Available Technology The technology available for use in system development is personal computer technology that is commercially available, computer storage media such as CD-
Wood Product Documents SIE 554A, Fall 2006 The average player with basic computer skills shall be able to use the system. At minimum, a player shall be able to use all system features upon completion of the tutorial. 2.6 Trade-off Criteria The cost of the system will carry a weight of 15%. The functional requirements will carry a weight of 65%. The additional utilization of resources shall carry a weight of 20% (schedule is of utmost important and therefore shall be treated as an independent variable). 2.7 Design Verification Design verification will be achieved via demonstration, inspection, test or analysis. Method used for verification of each requirement will be as described in Document 3. A detailed verification plan shall be agreed to by the customer prior to beginning design verification.
