VR Haptic Feedback Control Based on Posture Stability Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Haptic sensations in virtual reality environments can cause user startled depending on the type and magnitude of the user's posture when not yet stable, the user may be startled depending on the type and magnitude of the user's posture when the user's posture is not yet stable, the user may be startled depending on the type and magnitude of the haptic sensation, leading to a drop in operability.
Innovation Solution
An information processing device that includes a processor and memory, which executes acquisition, setting, and control processing to determine haptics-enabled and haptics-disabled regions and adjust haptic feedback based on the user's posture and virtual object position, ensuring stable haptic sensations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If haptic sensation is provided when user posture is not stable, then haptic feedback functionality is achieved, but user operability deteriorates due to startling
Solution Approach 1:
The system performs preliminary assessment of user posture stability before activating haptic feedback. By evaluating posture stability in advance and only enabling haptic effects when the user is in a stable state, the system prevents startling while maintaining haptic feedback functionality, thus resolving the contradiction between reliability and ease of operation
Solution Approach 2:
The system continuously monitors user posture and uses this feedback to dynamically control haptic feedback activation. When posture instability is detected, haptic feedback is suppressed; when stability is confirmed, haptic feedback is enabled. This closed-loop feedback mechanism ensures both reliable haptic functionality and high user operability
2Ease of operation
If haptic effect generation is controlled based on virtual object position, then user operability is improved, but system complexity increases
Solution Approach 1:
The system applies different haptic control strategies to different spatial regions. A first region is defined where haptic effects are suppressed to prevent startling, while a second region allows normal haptic effects. This localized quality approach improves user operability in critical regions while maintaining functionality in safe regions, with manageable system complexity
Solution Approach 2:
The virtual space is segmented into multiple regions with different haptic feedback characteristics. By dividing the space into zones with distinct haptic behaviors, the system achieves sophisticated control of user experience without requiring complex global control mechanisms, thus balancing operability improvement with system complexity

AI summary
An information processing device includes a processor, and a memory storing a program which, when executed by the processor, causes the information processing device to execute acquisition processing to acquire information about a physical characteristic of a virtual object, execute setting processing to set a first region and a second region different from the first region in a space where the virtual object is located, and execute control processing to, in a case where a position of the virtual object held by a user falls within the first region in the space, not control generation of a haptic effect based on the information, and in a case where the position falls within the second region, control the generation of the haptic effect.
