A controller device with a vibrating element, reception, acquisition, and vibration control means that adjusts vibration intensity and frequency based on hand contact state information, ensuring consistent user feedback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the controller device is fastened to the user's hand with a fixed method, then the device structure is simple, but the degree of close contact varies from one play to another causing unstable vibration perception

Engineering Contradiction:

Improvevibration perception consistencyVSAvoidcontact state detection system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The controller device dynamically adjusts vibration intensity based on real-time contact state detection. The vibration control unit modifies vibration parameters according to the detected contact degree, transforming a static vibration system into a dynamic one that adapts to varying user-hand contact conditions, thereby ensuring consistent vibration perception across different plays.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The device incorporates a feedback mechanism where the vibration control unit receives contact state information from detection units and adjusts vibration intensity accordingly. This closed-loop feedback system ensures that vibration perception remains consistent by continuously monitoring and responding to changes in contact degree between the controller and user's hand.

Inventive Principle:

Principle #23Feedback

2Reliability

If the vibration intensity is increased to compensate for poor contact, then the vibration perception is improved, but the vibration becomes excessively strong when contact is already good

Engineering Contradiction:

Improvevibration perception stabilityVSAvoidexcessive vibration intensity

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The vibration control unit changes vibration parameters (intensity, frequency) based on the detected contact state. When contact degree is high, the system reduces vibration intensity to prevent excessive strength, while when contact degree is low, it increases intensity to ensure adequate perception. This dynamic parameter adjustment eliminates the harmful effect of excessively strong vibration while maintaining reliable vibration perception stability.

AI summary

An information processing system includes a controller device to be fastened to a user's hand and an information processing apparatus that is connected to the controller device to exchange information with the controller device. The controller device includes a vibrating element causing a housing of the controller device to vibrate, receives information indicating a vibration intensity of the vibrating element, and acquires information related to a contact area between the controller device and the user's hand so as to cause the vibrating element to vibrate. Also, the controller device or the information processing apparatus corrects information indicating the vibration intensity on a basis of information acquired by acquisition means of the controller device.
