Golf Game Apparatus Target Position Setting with Power Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf game technologies do not allow for simple and intuitive setting of a target position for a ball object in a virtual space, particularly when considering terrain undulations and shot power limitations.
Innovation Solution
A golf game apparatus with a mark displaying portion, determining portion, and power calculating portion that displays a target shot power for moving a ball object to a designated position in a virtual space, taking into account terrain undulations and club parameters, allowing players to easily set the target position with a simple operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the player manually sets the target position and calculates shot power in existing golf games, then the game can be played, but the operation becomes complex and time-consuming
Solution Approach 1:
The system pre-calculates and displays multiple candidate target positions (first through fourth positions) based on the current ball position and terrain information before the player makes a selection. This preliminary preparation eliminates the need for manual calculation of shot power and trajectory, allowing players to simply select from predefined options.
Solution Approach 2:
The system creates virtual target position markers that are displayed on the operation screen at locations corresponding to calculated landing positions. These visual copies of target positions allow players to intuitively select destinations without performing complex calculations or measurements.
2Reliability
If the game calculates shot power considering terrain undulations and club parameters, then the golf simulation becomes more realistic, but the calculation complexity increases
Solution Approach 1:
The shot power calculation is divided into discrete segments corresponding to different club types (wood, iron, putter). Each club type has pre-stored parameter sets including club length, weight, and loft angle. The system selects and applies the appropriate segment based on player input, simplifying the overall calculation process while maintaining accuracy.
Solution Approach 2:
The system varies calculation parameters based on terrain conditions, applying different gravitational acceleration values and resistance coefficients depending on whether the ball is moving uphill, downhill, or on flat ground. This parameter adaptation allows accurate shot power calculation across diverse terrain without requiring a completely separate calculation system for each condition.
3Loss of information
If the game provides detailed terrain information and multiple shot options, then the player can make better decisions, but the information display becomes overwhelming
Solution Approach 1:
The operation screen displays terrain information and target positions selectively based on the current ball location and relevant shot options. Only the first through fourth target positions and associated terrain data are shown, filtering out unnecessary information. This localized display approach provides comprehensive relevant information without overwhelming the player with extraneous details.

AI summary
A non-limiting example game apparatus includes a first LCD and a second LCD, a touch panel is provided on the second LCD. A pre-hitting operation screen is displayed on the second LCD, and a mark for designating a target landing point is displayed in this screen. A player designates a desired target landing point by moving the mark by a touch operation. A target shot power value for causing a ball to arrive the designated target landing point is calculated with using parameters set for a club that is currently selected. However, when the designated target landing point exceeds a position that the ball is hit using the club under selection with a maximum power value, the mark is moved to the position concerned and the maximum power value is set as a target shot power value.
