Dual-Display Game Machine Virtual Camera Focus Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional game machines often impair the virtual game space image by displaying marks or cursors to indicate the selected character or focus point, making it difficult for players to identify the selected object and navigate the game space enthusiastically.
Innovation Solution
A game machine with a dual-display system, where the first display unit shows the game scene captured by a virtual camera, and the second display unit allows players to specify a focus target through feature information, without overlaying additional images on the game space, enabling intuitive selection and navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If marks or cursors are displayed to indicate the selected character or focus point, then the player can identify the selected object, but the virtual game space image is impaired and the selected object becomes difficult to view
Solution Approach 1:
The patent divides the display into two separate display units: the first display unit shows the virtual game space without any obstructing marks, while the second display unit displays feature information and selection interfaces. This segmentation allows the game space to remain visually clear while still providing necessary selection indicators through the separate second display unit.
Solution Approach 2:
The patent introduces a second display unit as an intermediary interface between the player and the game space. Instead of directly marking objects in the game space, the system uses the second display unit to show feature information, portraits, and selection indicators, serving as a mediator that provides selection feedback without contaminating the visual integrity of the game space.
2Ease of operation
If the focus point is determined by player operation, then the player can navigate the game space, but additional images or cursors must be displayed which obstruct the game space view
Solution Approach 1:
The patent segments the navigation and selection interface from the game space display by using a second display unit. The first display unit remains free of cursors or focus markers, while the second display unit handles all navigation controls and focus point indicators, allowing easy operation without visual obstruction in the game space.
Solution Approach 2:
The second display unit serves as an intermediary control interface that handles all navigation and focus-point-setting operations. Players interact with this separate interface to control the virtual camera and set focus points, eliminating the need to display cursors or markers within the game space itself.
3Area of stationary object
If multiple objects are present in a small area, then the game space is compact, but it becomes very difficult to identify the currently-selected object by determining the focus point
Solution Approach 1:
The patent segments the object identification function from the game space view by displaying feature information, portraits, and selection status on the second display unit. This allows compact game space design while maintaining clear object identification through the separate information display interface.
Solution Approach 2:
The second display unit acts as an intermediary that resolves the difficulty of identifying selected objects in compact game spaces. It provides detailed feature information, portraits, and selection indicators that would be impossible to display clearly within the limited game space area, thereby solving the identification problem without requiring more game space.

AI summary
A game machine is provided with two display units, that is, a first LCD and a second LCD. On the second LCD, feature information unique to each object located in a virtual game space is displayed. When a player selects, based on information displayed on the second LCD, one of the objects provided in the virtual game space, a focus point of a virtual camera provided in the virtual game space is set so that the virtual camera is oriented to a direction of the selected object, and the state of the virtual game space captured by the virtual camera is displayed on the first LCD. With this, the virtual game space can be displayed without impairing its worldview. Also, the player can be allowed to easily specify a desired focus target in the virtual game space.
