Touch Panel Contact Area Detection for Game Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing devices with numerous operation buttons on screens can hinder game operation convenience due to clutter, making it difficult for users to see and interact with objects effectively.
Innovation Solution
An information processing device that uses a touch panel to detect touch operations, determining the contact surface area to differentiate between first and second operations, allowing users to control object actions by changing the size of the contact surface area, thereby reducing the need for multiple operation buttons and enhancing operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operation buttons are disposed on the screen to enable more actions, then the object can perform more actions, but the object becomes harder to see and operability deteriorates
Solution Approach 1:
The patent changes the parameter of touch contact surface area to differentiate between operation types. By detecting whether the contact area is large or small, the system distinguishes between first operations (e.g., movement) and second operations (e.g., attacks), eliminating the need for multiple physical buttons while maintaining diverse action capabilities.
2Adaptability or versatility
If multiple operation buttons are disposed on the screen to enable more actions, then the object can perform more actions, but the screen layout becomes cluttered and visibility of the object deteriorates
Solution Approach 1:
The patent extracts the operation type differentiation function from physical button distinctions and relocates it to the touch contact surface area parameter. This removes the need for multiple discrete buttons on the screen, freeing up screen space while preserving the ability to execute multiple different actions.
3Adaptability or versatility
If multiple operation buttons are disposed on the screen to enable more actions, then the object can perform more actions, but the device complexity increases
Solution Approach 1:
The patent makes the touch panel universally functional by enabling it to detect multiple operation types through a single interface. The touch panel detects both first operations and second operations by analyzing the contact surface area, making one component serve multiple functions and reducing overall device complexity.

AI summary
An information processing device includes: a controller that generates a game image of an object disposed in a virtual game space; and a touch panel that displays the game image. The touch panel detects an input of a user's touch operation on the game image and outputs, to the controller, a detection signal indicating the detection of the input. The controller determines a contact surface area at an indicated position on the touch panel indicated by the user's touch operation based on the detection signal. The controller determines, based on a size of the contact surface area, whether ae first operation or a second operation has been inputted. The controller performs a first control related to the object in response to the first operation, and a second control related to the object when the second operation has been inputted.
