Electronic Scorebook Creation Device with Predictive Fielder Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic scorebook creation systems require waiting for a fielder to catch a batted ball before inputting entries, leading to delays in recording scores during a baseball game.
Innovation Solution
An electronic scorebook creation device with a display unit, operation input unit, and processor that displays a field image with position information of fielders, allows users to input predicted catch positions, determines catching fielder, batted ball type, and batting result candidates, and creates an electronic scorebook based on user selections, enabling quick input without waiting for the actual catch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the conventional method of waiting for a fielder to catch the ball before inputting entries is used, then the accuracy of scorekeeping is maintained, but the time required for recording scores increases
Solution Approach 1:
The system performs preliminary actions by automatically determining the catching fielder candidate order, batted ball type candidate order, and batting result candidate order based on fielder positions and ball trajectory before the user needs to input data. This pre-processing of information reduces the time required for actual input while maintaining accuracy through user confirmation of the pre-determined candidates.
2Measurement precision
If manual entry of all scorekeeping information is required, then complete control over data accuracy is maintained, but the complexity of the operation increases
Solution Approach 1:
The system performs self-service by automatically generating candidate information for catching fielders, batted ball types, and batting results based on fielder positions and ball trajectory data. This self-generated information is then presented to the user for confirmation, reducing the manual input burden while maintaining data accuracy through user verification.
Solution Approach 2:
The system provides feedback to the user by displaying candidate information that has been automatically determined based on fielder positions and ball trajectory. This feedback mechanism allows users to review and confirm the pre-determined information, ensuring data accuracy while simplifying the overall operation.
3Measurement precision
If a detailed field image with position information is displayed, then the precision of fielder position tracking is improved, but the device complexity increases
Solution Approach 1:
The field image display serves multiple functions: it shows fielder positions for tracking precision, provides the basis for determining catching fielder candidates, and visualizes ball trajectory information. This multi-functionality allows the system to achieve high position tracking precision without proportionally increasing device complexity, as the same display infrastructure supports multiple analytical purposes.

AI summary
An electronic scorebook creation device determines a catching fielder candidate order in which multiple fielders are arranged on the basis of operation input to a displayed field image and the positions of the fielders on the field image, and displays a catching fielder selection button group in which the fielders are arranged according to the catching fielder candidate order. The electronic scorebook creation device also determines a batted ball type candidate order in which batted ball type candidates are arranged, and displays a batted ball type selection button group in which batted ball type candidates are arranged according to the batted ball type candidate order. The electronic scorebook creation device further determines a batting result candidate order in which batting result candidates are arranged, and displays a batting result selection button group in which batting result candidates are arranged according to the batting result candidate order.
