Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are used to acquire diverse feature data, then measurement precision and interaction accuracy are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensor types (cameras, gyroscopes, accelerometers, barometers, humidity sensors, temperature sensors) into an integrated sensor system within the VR glasses. These sensors are merged to collectively capture comprehensive feature data including line-of-sight information, head movement, environmental temperature, and humidity, thereby improving measurement precision while managing device complexity through integration.
Solution Approach 2:
The sensor system is designed with multi-functionality to serve multiple purposes: cameras capture line-of-sight and environmental images, gyroscopes and accelerometers track head movement, while environmental sensors monitor temperature and humidity. This universal sensor platform improves various measurement accuracies simultaneously without requiring separate dedicated systems for each function.
2Measurement precision
If environmental feature data is incorporated into interactive control, then interaction accuracy is improved, but data processing complexity increases
Solution Approach 1:
The data processing system is segmented into specialized modules: a sensor data acquisition module collects raw data from multiple sensors, a feature data processing module extracts relevant features, and an interactive control module generates control instructions. This segmentation allows the system to handle complex environmental and biological data through distributed processing, improving interactive control accuracy while managing overall system complexity.
Solution Approach 2:
The patent introduces an intermediary processing layer that receives raw feature data from sensors, processes and integrates this data, and then outputs refined information to the interactive control system. This intermediary module acts as a mediator between complex sensor inputs and control outputs, enhancing processing accuracy while abstracting the complexity of handling multiple data sources.
