Solution Overview
Problem
Conventional game systems inadequately express game statuses through controller vibrations, failing to provide a clear and intuitive representation of game operations and statuses to players.
Innovation Solution
A game system incorporating a controller with an inertia sensor and a vibrating portion, where the vibration intensity, frequency, and waveform are dynamically adjusted based on the speed and orientation of the controller's operation, allowing for more precise and intuitive feedback of game statuses to the player.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the controller is simply vibrated when a predetermined game condition is satisfied, then the controller provides basic vibration feedback, but the game status cannot be sufficiently expressed and the player cannot specifically recognize the game status
Solution Approach 1:
The patent applies parameter changes by varying multiple vibration parameters (intensity, frequency, waveform pattern) to encode different game status information. The determination section analyzes operation data and generates vibration signals with specific parameter combinations that represent different game states, allowing rich information transmission without increasing hardware complexity.
Solution Approach 2:
The system uses dynamics by making the vibration characteristics adaptive and variable based on real-time game conditions. The vibration signal is dynamically adjusted according to the determined game status, creating a flexible feedback system that can express multiple states using a single vibrating portion through changing its vibration behavior over time.
2Loss of information
If the vibration intensity is increased to express game status more clearly, then player recognition improves, but the vibration feedback becomes less nuanced and cannot express different game states distinctly
Solution Approach 1:
The patent applies local quality by using different vibration parameters (intensity, frequency, waveform) as distinct channels for encoding information. Each parameter dimension provides localized differentiation capability, allowing the system to convey nuanced game status information through coordinated variations across multiple parameter dimensions rather than relying on a single parameter.
3Loss of information
If multiple vibration parameters are adjusted to express game status specifically, then information transmission improves, but the control system becomes more complex
Solution Approach 1:
The patent applies universality by using a single vibrating portion to perform multiple functions through varying its vibration parameters. The same physical component can express different game statuses by changing intensity, frequency, and waveform characteristics, eliminating the need for multiple separate vibration actuators while maintaining rich feedback capability.
