Game Controller Vibration Feedback Loop for State-Aware Haptics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional game systems cannot accurately monitor the vibration output state of controllers, leading to inefficiencies in vibration feedback transmission.
Innovation Solution
A vibration control system where a first apparatus receives vibration instruction data, generates and stores vibration state data, and transmits it to a second apparatus, allowing the second apparatus to determine and adjust subsequent vibration instruction data based on the received state, enabling accurate monitoring and control of vibration output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If vibration instruction data is transmitted at predetermined intervals, then the control system operates with simple timing, but the game apparatus main body cannot understand the vibration output state of the controller
Solution Approach 1:
The controller transmits vibration state data back to the game apparatus main body, creating a feedback loop. This allows the main body to understand the actual vibration output state and adjust subsequent instruction data accordingly, resolving the information loss problem while maintaining simple communication protocols
Solution Approach 2:
The controller autonomously generates and transmits vibration state data without requiring the main body to query it. The controller serves itself by automatically reporting its state, eliminating the need for complex request-response protocols while ensuring information availability
2Measurement precision
If vibration state data is transmitted from controller to main body, then accurate vibration state monitoring is achieved, but data transmission time and system complexity increase
Solution Approach 1:
The vibration state data transmission is merged with the existing communication framework between controller and main body. By combining state reporting with regular communication cycles, the system achieves accurate monitoring without adding separate transmission channels or increasing overall communication time
Solution Approach 2:
The controller prepares vibration state data in advance during vibration execution and transmits it at optimal moments. This preliminary preparation ensures data is ready for immediate transmission, minimizing delay while maintaining monitoring accuracy
Data Source
AI summary
Vibration instruction data transmitted from another apparatus is received, data related to the vibration instruction data is stored in a memory, and a vibration apparatus is vibrated using the data stored in the memory. On the other hand, vibration state data indicating a vibration state of the vibration apparatus is generated, and the vibration state data is transmitted to the other apparatus.
