Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current game controllers with vibrators lack effective methods to enhance user accessibility through tactile feedback, particularly in navigating user interfaces and enabling vibration functions based on user preferences.
Innovation Solution
An information processing device connected to an input device with left and right-side vibrators that receives directional inputs and adjusts vibration intensity based on focus movement, enabling vibration functions for user interfaces when enabled by the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vibration functions are added to enhance user accessibility, then user accessibility is improved, but device complexity increases
Solution Approach 1:
The vibrator is designed to serve multiple functions: providing tactile feedback during game play and enabling user interface navigation assistance. This multi-functionality allows the same hardware component to address both game feedback needs and accessibility requirements without requiring separate dedicated systems.
Solution Approach 2:
The vibration characteristics are made dynamic and adjustable based on context. The system can modulate vibration intensity, frequency, and duration according to whether it is providing game feedback or accessibility assistance, allowing flexible adaptation to different usage scenarios without requiring multiple fixed vibration mechanisms.
2Ease of operation
If vibration intensity is increased to improve tactile feedback, then user accessibility is improved, but harmful factors increase
Solution Approach 1:
The vibration intensity is dynamically adjusted based on the operational context. During game play, moderate vibration intensity provides sufficient tactile feedback without causing discomfort. During user interface navigation, the system can apply gentler vibration patterns that are sufficient for accessibility without overwhelming the user, thereby adapting the harmful factor level to the specific use case.
Solution Approach 2:
The vibrator employs periodic vibration patterns with varying intensities and durations. Rather than sustained high-intensity vibration, the system uses intermittent vibration cycles that provide clear tactile feedback while allowing brief recovery periods, reducing the cumulative harmful effect on the user's hand and wrist.
3Ease of operation
If vibration control signals are added to existing game controllers, then user accessibility is improved, but device complexity increases
Solution Approach 1:
The vibration control functionality is merged with the existing game controller architecture. The vibrator is integrated into the controller's existing processing and communication systems, sharing resources such as the microcontroller, power management, and wireless communication modules. This consolidation allows accessibility features to be added without proportionally increasing overall device complexity.
Solution Approach 2:
The controller's existing processing units and communication interfaces are designed to handle both traditional game control inputs and vibration control signals for accessibility features. This universal design allows the same hardware infrastructure to support multiple functions without requiring separate dedicated systems for vibration control.
