Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If biometric monitoring systems are used in virtual reality environments, then user identification and personalized control capability is improved, but device complexity and system integration requirement increases
Solution Approach 1:
The patent combines multiple biometric monitoring functions (heart rate, blood oxygen saturation, temperature) into a single wearable accessory that integrates with the virtual reality system. This merging approach enables comprehensive user identification and personalized control while managing system complexity through unified hardware design.
Solution Approach 2:
The wearable accessory is designed to perform multiple functions simultaneously: biometric data collection, user identification, and control signal generation. This multi-functionality allows the system to provide personalized control across various applications (home appliances, vehicle systems, security) without requiring separate dedicated devices for each function.
2Measurement precision
If multiple biometric parameters are monitored simultaneously, then user identification accuracy and personalized control precision is improved, but energy consumption and data processing load increases
Solution Approach 1:
The system monitors biometric parameters periodically rather than continuously, collecting data at specific intervals during virtual reality usage. This periodic monitoring approach maintains user identification accuracy by capturing relevant biometric changes while significantly reducing energy consumption compared to continuous monitoring.
Solution Approach 2:
The system monitors biometric parameters at a level that exceeds basic identification needs during certain phases of virtual reality usage, then processes and stores this data for later personalized control applications. This approach ensures high identification accuracy when needed while allowing energy management during less critical periods.

Function Achieved in This Case
Enables intelligent, secure, and interactive control of various systems and devices by recognizing individual users, enhancing user experience and energy efficiency through personalized device operation.
Implementation Method 1
An optical pulse oximeter generally emits a red light beam (wavelength of about 660 nm) and an infrared light beam (wavelength of about 910 nm) to penetrate a part of the human body and detects an intensity variation of the penetrating light based on the feature that the oxyhemoglobin and the deoxyhemoglobin have different absorptivities in particular spectrum
Data Source
AI summary
A virtual reality system including an image viewing device and a wearable accessary is provided. The image viewing device detects a biometric characteristic to identify a user ID according to the biometric characteristic, outputs an ID signal associated with the identified user ID and shows video stream associated with the identified user ID. The wearable accessary detects an attached status and movement of the wearable accessary after receiving the ID signal, and sends a control signal to the image viewing device to change image content in the video stream according to the detected movement of the wearable accessary when the attached status indicates continuous wearing.
