Recording Medium Program for Touch-Pressure Game Input Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices using touch panels are prone to unintended input when the user's touch position deviates from a neutral area, leading to erroneous instructions.
Innovation Solution
A system that utilizes touch position and pressure information to determine the presence and direction of game instructions, employing a touch panel with defined areas and pressure thresholds to prevent unintended inputs by maintaining a neutral state through pressure adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch panel is used to receive user input, then the ease of operation is improved, but unintended instructions are input when the touch position deviates from the neutral area
Solution Approach 1:
The system changes the parameter used for input detection from touch position alone to a combination of touch position and pressure information. By introducing pressure as an additional parameter, the system can distinguish between intentional inputs (with sufficient pressure) and unintentional contacts (with insufficient pressure), thereby resolving the contradiction between ease of operation and reliability
Solution Approach 2:
Pressure information acts as an intermediary parameter that mediates between the touch position and the final input determination. The pressure threshold serves as a filtering mechanism that allows the system to accept touch inputs while rejecting unintended contacts, thus improving reliability without compromising the ease of operation
2Reliability
If pressure information is used to determine input presence, then the reliability of input detection is improved, but the device complexity increases
Solution Approach 1:
The touch panel is designed to serve multiple functions: it detects both touch position and pressure information using the same hardware component. This multi-functionality approach allows the system to improve reliability through pressure detection without adding separate dedicated sensors, thereby minimizing the increase in device complexity
3Reliability
If a neutral area is required to prevent unintended input, then the reliability is improved, but the ease of operation deteriorates as users must reposition their touch
Solution Approach 1:
The system changes the basis for input validation from spatial position (requiring neutral area) to pressure magnitude. This parameter change eliminates the need for users to reposition their touch to a specific neutral area, as long as the applied pressure exceeds the threshold, thereby maintaining reliability while improving ease of operation

AI summary
A non-transitory computer-readable recording medium has recorded therein a program for causing a processor to function as: a touch position information acquirer configured to acquire touch position information regarding a touch position on a touch panel; a pressure information acquirer configured to acquire pressure information regarding a pressure applied to the touch panel; an input presence determiner configured to determine, based on the pressure information acquired by the pressure information acquirer, whether input of an instruction regarding a game is present; and an instruction determiner configured to determine a direction regarding the game indicated by the instruction, based on the touch position information acquired by the touch position information acquirer, when a determination result by the input presence determiner is affirmative.
