HMD Device Dynamic Massage Control for Content Urgency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display (HMD) devices do not effectively synchronize massage chair operations with the urgency level of content being viewed, leading to potential distractions or missed important scenes during high-urgency content due to inconsistent massage strengths.
Innovation Solution
An HMD device that adjusts massage strength and mode based on the urgency degree of the content by transmitting commands to a massage chair, increasing strength during low-urgency content and reducing strength during high-urgency content to maintain a realistic experience and prevent distractions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the HMD device increases massage strength during high-urgency content, then the realism of the virtual reality experience is improved, but the user's viewing of content is disturbed
Solution Approach 1:
The massage strength is made dynamic by continuously adjusting it according to the urgency degree of the content being viewed. The system transitions from static massage strength to dynamic adjustment based on real-time content analysis, allowing the massage intensity to vary with the narrative urgency of the virtual reality experience.
Solution Approach 2:
The physical parameter of massage strength is changed based on the urgency degree parameter of the content. The system monitors content urgency and translates it into corresponding massage strength adjustments, creating a mapping between digital content parameters and physical massage parameters.
2Object-affected harmful factors
If the HMD device reduces massage strength during high-urgency content, then the user's viewing of content is not disturbed, but the feeling similar to the urgency of the content is lost
Solution Approach 1:
The system implements dynamic control of massage strength that responds to real-time content urgency. Rather than maintaining a fixed massage pattern, the system continuously adapts the massage intensity to match the narrative flow, creating a synchronized experience between visual content and tactile feedback.
Solution Approach 2:
The system employs feedback mechanisms where the urgency degree of the content is continuously monitored and used to adjust the massage strength. This closed-loop control ensures that the massage experience remains synchronized with the virtual reality content, preventing both excessive distraction and loss of realism.
3Device complexity
If the HMD device uses fixed massage strength throughout content playback, then the device complexity is reduced, but the user experience is less optimized
Solution Approach 1:
The massage control system transitions from a static, fixed-strength configuration to a dynamic system that automatically adjusts intensity. This adds intelligence to the system, allowing it to adapt to different content scenarios without requiring complex manual controls or multiple physical settings.
Solution Approach 2:
The system performs self-adjustment of massage strength based on automatic analysis of content urgency. The HMD device independently monitors the content and makes appropriate massage intensity adjustments without user intervention, simplifying the user interface while enhancing the personalized experience.

AI summary
A head mounted display (HMD) device including a display configured to display content; a communication processor configured to communicate with a massage chair; and a controller configured to acquire information about an urgency degree of the displayed content, and transmit a control command to the massage chair for controlling the massage chair to perform a massage corresponding to the urgency degree.
