Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality head-mounted displays lack efficient communication and sensing capabilities to dynamically adjust multimedia content based on user position, biometric data, and environmental information, leading to suboptimal user experience and potential eyestrain due to fixed display settings.
Innovation Solution
A virtual reality system comprising a head-mounted display apparatus with a multi-sensing module, multimedia module, and wireless communication units that allow for real-time sensing of user and environmental data, enabling dynamic modulation of multimedia content and display parameters, such as brightness and refresh rate, to enhance user experience and prevent eyestrain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed display settings are used in HMD, then device complexity is reduced, but user comfort deteriorates due to eyestrain
Solution Approach 1:
The patent implements dynamic display parameters that automatically adjust based on detected user state. The processing circuitry modifies refresh rate, brightness, and other display settings in real-time according to user biometric data from sensors, transforming static display configurations into adaptive dynamic settings that prevent eyestrain while managing complexity.
Solution Approach 2:
The system incorporates feedback loops where sensors continuously monitor user biometric data (such as eye movement, pupil dilation, or other physiological indicators), and the processing circuitry uses this feedback to automatically adjust display parameters. This closed-loop feedback mechanism enables the display to adapt to user needs without manual intervention, resolving the contradiction between simplicity and comfort.
2Adaptability or versatility
If multi-sensing modules and dynamic adjustment capabilities are added, then user experience is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple sensing capabilities (motion sensors, biometric sensors, environmental sensors) into a unified head-mounted display system where a single processing circuitry handles diverse functions including display rendering, sensor data processing, and parameter adjustment. This multi-functional integration approach enhances adaptability while managing overall system complexity through shared processing resources.
Solution Approach 2:
The system combines multiple previously separate functions (display control, motion tracking, biometric monitoring, environmental sensing) into an integrated head-mounted display unit with unified processing. By merging these functions into a single device with shared processing circuitry, the patent achieves enhanced user experience while avoiding the complexity of multiple separate systems.
3Measurement precision
If real-time sensing and dynamic modulation are implemented, then depth perception is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic or event-triggered sensing and display updates rather than continuous operation. The system monitors user state at intervals or triggers adjustments based on specific events (such as detected eye strain indicators), reducing the frequency of full system operations while maintaining depth perception quality. This periodic action reduces energy consumption compared to continuous real-time processing.
Solution Approach 2:
The system dynamically changes display parameters (refresh rate, brightness, resolution) based on user state and environmental conditions. When high precision depth perception is needed, the system increases measurement frequency and display quality; when user state is stable, it reduces these parameters to conserve energy. This adaptive parameter adjustment balances measurement precision with power consumption.
