Game Controller Haptic Control With Wide-Band Vibration Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current game controllers with eccentric motors provide limited tactile feedback, lacking the ability to freely control drive frequency and strength, and are not responsive enough to express detailed vibrations such as latch feeling or rough textures, leading to a less immersive gaming experience.
Innovation Solution
An information processing apparatus and method that includes a control section capable of changing control on a tactile feedback apparatus based on recognized feedback types, utilizing a wide-band vibrating device externally attached to the game controller, which can independently control vibration amplitude and frequency, enhancing tactile feedback beyond what eccentric motors can provide.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple applications are operated simultaneously in a smartphone, then functional versatility is improved, but memory resources are depleted and processing speed deteriorates
Solution Approach 1:
The system continuously monitors memory usage and application states, using this feedback to dynamically adjust resource allocation. The processor determines whether to suspend or terminate applications based on real-time memory status, creating a closed-loop control system that balances versatility and performance
Solution Approach 2:
The patent implements dynamic resource management where application states can change between active, suspended, and terminated based on system conditions. This dynamic adjustment allows the system to adapt memory allocation in real-time, maintaining processing speed while supporting multiple applications
2Adaptability or versatility
If memory resources are allocated to multiple simultaneous applications, then functional versatility is improved, but available memory for current operations deteriorates
Solution Approach 1:
The system segments memory resources by creating distinct memory spaces for active and suspended applications. This segmentation allows the system to maintain multiple applications in memory simultaneously while isolating their resource usage, enabling versatility without permanently reducing available memory for current operations
Solution Approach 2:
The patent implements a mechanism where suspended application memory can be recovered when no longer needed. The system discards memory allocations from suspended applications and makes them available for active operations, dynamically reconciling versatility with available memory quantity
3Quantity of substance
If application execution is suspended to conserve memory, then available memory is improved, but user convenience deteriorates due to restart requirements
Solution Approach 1:
The system performs preliminary suspension of applications in low-memory conditions, preserving their state in memory rather than fully terminating them. This preliminary action allows rapid resumption when memory becomes available, maintaining user convenience while temporarily conserving memory resources

AI summary
[Object] Tactile feedback that a user can acquire is limited because a game controller includes only a specific vibrating device and game software supports only the specific vibrating device. [Solution] An information processing apparatus including: a control section configured to generate a control signal that controls an operation of a tactile feedback apparatus including a tactile feedback section. The control section changes control on the tactile feedback apparatus on the basis of a type of the tactile feedback section which is recognized by the control section.
