VR Controller Pointer Stabilization During Button Presses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control methods for mixed reality and virtual reality systems using hand-held controllers fail to accurately maintain the indicator position due to hand gestures, leading to unintended shifts during button operations.
Innovation Solution
An information processing apparatus that uses an HMD and a controller to detect hand and finger movements, adjusting the indicator position based on captured images and sensor data to restrict movements caused by hand gestures, thereby maintaining the intended position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the indicator position follows the motion of the operation unit, then the user can intuitively control the indicator, but the indicator position shifts unintentionally during button operations
Solution Approach 1:
The system dynamically adjusts the coupling between hand motion and indicator position based on operational context. During button-pressing operations, the coupling is reduced to prevent unintended shifts, while during navigation operations, the coupling is strengthened for intuitive control. This dynamic adaptation resolves the contradiction by making the system behavior context-dependent rather than fixed.
Solution Approach 2:
The system changes the parameter of indicator position responsiveness based on the detected operation type. When a button press is detected, the system temporarily reduces the responsiveness parameter to maintain indicator stability. When navigation is detected, the responsiveness parameter is increased for intuitive following. This parameter modulation allows the system to optimize for different operational requirements.
2Manufacturing precision
If the indicator position is fixed during button operations, then the accuracy of input is maintained, but the user experiences input lag
Solution Approach 1:
The system performs preliminary detection of button-pressing operations and proactively adjusts indicator position behavior before unintended shifts occur. By detecting the button press intent early and preemptively stabilizing the indicator position, the system prevents the need for corrective actions and reduces overall input latency while maintaining accuracy.
Solution Approach 2:
The system continuously monitors hand motion and operation state, providing real-time feedback to adjust indicator position behavior. When button press is detected, the feedback mechanism activates to stabilize the indicator. This closed-loop control ensures that the indicator remains stable during critical input moments while responding appropriately to user actions, balancing accuracy and responsiveness.
3Ease of operation
If the system detects hand finger gestures to control indicator position, then the ease of operation is improved, but unintended shifts occur during button pressing
Solution Approach 1:
The system dynamically modulates the sensitivity and responsiveness of indicator position to hand gestures based on the detected operation context. During button-pressing operations, the sensitivity is reduced to ignore minor gestures that cause unintended shifts. During navigation operations, the sensitivity is increased to respond to intentional gestures. This dynamic sensitivity adjustment maintains both ease of operation and input reliability.
Solution Approach 2:
The system changes the parameter of gesture responsiveness based on operational state. When a button press is detected, the gesture responsiveness parameter is temporarily lowered to prevent unintended indicator shifts. When navigation is detected, the parameter is raised for smooth control. This parameter modulation allows the system to distinguish between intentional navigation gestures and incidental movements during button operations.
