Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions do not adequately enable players to control video games on mobile devices without hardware joysticks or triggers, limiting the gaming experience on these platforms.
Innovation Solution
A system that uses a processor to identify the magnitude of touch input on a touch-enabled display, allowing actions such as changing attack modes, weapon selection, character movement speed, and emotional expressions in video games based on the force and size of touch inputs, utilizing pressure sensors and relational databases to correlate input with game actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video games are played on mobile devices without dedicated hardware controllers, then device portability and accessibility are improved, but control precision and gameplay complexity are limited
Solution Approach 1:
The touch-enabled display serves multiple functions: it acts as both the game display and the input controller. The screen can detect various touch magnitudes and translate them into different control commands, allowing a single component to replace multiple dedicated controller elements like buttons, joysticks, and triggers.
Solution Approach 2:
The system detects changes in touch magnitude parameters (pressure, contact area, duration) and translates these continuous parameter variations into discrete control actions. Different magnitude thresholds trigger different game commands, enabling fine-grained control without additional hardware.
2Measurement precision
If touch magnitude detection is implemented on mobile devices, then control precision and gameplay variety are improved, but device complexity and processing requirements increase
Solution Approach 1:
The touch-enabled display utilizes its existing pressure-sensitive capabilities to detect touch magnitude, rather than requiring separate sensor components. The display's native touch detection mechanism is extended to provide magnitude information, allowing the system to leverage existing infrastructure for enhanced functionality.
Solution Approach 2:
The patent replaces mechanical controller components (physical buttons, joysticks, triggers) with software-based interpretation of touch magnitude data. The mechanical input system is substituted with a digital sensing and processing approach that uses the touch display's electrical characteristics to infer physical touch parameters.
3Adaptability or versatility
If multiple touch magnitude thresholds are used for different game actions, then gameplay versatility and character control options are improved, but input recognition complexity and false action triggering increase
Solution Approach 1:
The system dynamically adjusts touch magnitude thresholds based on game context and current state. Rather than using fixed thresholds, the system can adapt the magnitude requirements for different actions based on gameplay situation, reducing false positives while maintaining versatility. The threshold values are not static but can change during game execution.
Solution Approach 2:
The system provides feedback mechanisms to confirm detected touch magnitudes before executing actions, or uses haptic feedback to inform users when their touch magnitude has been registered. This feedback loop helps prevent misinterpretation of touch inputs and allows users to adjust their input technique to achieve desired actions.
