Virtual Touch Area Mapping for Large Game Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large touch screens in gaming devices require significant finger movement for input, making it difficult for players to perform operations efficiently, especially when the screen size increases, and existing solutions like easy access functions either complicate operations or hide lower screen parts.
Innovation Solution
A game system that sets a virtual touch area smaller than the entire screen, allowing players to input operations within this area, with coordinates from the virtual touch area being mapped to screen coordinates, enabling game processes using these mapped coordinates as input, and switching between virtual and normal input modes based on game status or player preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the touch screen size is increased, then the display area is improved, but the finger movement distance required for input operations increases
Solution Approach 1:
The patent divides the touch screen into two functional zones: a virtual touch area (first area) for input operations and the remaining screen area (second area) for display. This segmentation allows the input operations to be confined to a smaller region while maintaining access to the full display area, resolving the contradiction between large display area and limited finger movement.
2Ease of operation
If easy access functions are implemented to reduce finger movement, then the ease of operation is improved, but the operations become complicated or lower screen parts are hidden
Solution Approach 1:
The patent extracts the input function from the entire screen and concentrates it in the virtual touch area at the lower end of the screen. This extraction allows input operations to be performed in a dedicated region without complicating the overall operation system or hiding display content, as the virtual touch area is positioned to not interfere with the display of the second area.

AI summary
The game system includes a processor including hardware. The processor performs a reception process of receiving coordinates of a touching operation in a touch screen as touching operation coordinates when the touching operation is performed by a player with respect to the touch screen; a virtual touch area process of associating the touching operation coordinates in the virtual touch area set in the touch screen as an area smaller than the touch screen with mapping coordinates on the touch screen; when the touching operation is performed with respect to the virtual touch area, an input process of setting the mapping coordinates as input coordinates, assuming that the touching operation is performed with respect to the mapping coordinates associated with the touching operation coordinates in the virtual touch area in which the touching operation is performed; and a game process based on the input coordinates.
