Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional human-computer interaction methods (gesture, expression, voice) are used, then interaction naturalness is improved, but interpretation accuracy and reliability deteriorate
Solution Approach 1:
The patent replaces traditional mechanical interaction methods (gesture recognition, expression analysis, voice processing) with a physiological signal-based system. By substituting the mechanical sensing approach with EEG detection, the system directly captures neural activity related to head motions, thereby improving interpretation accuracy while maintaining interaction naturalness through head movement control.
Solution Approach 2:
The patent introduces EEG detection information as an intermediary between head motions and control information. Instead of directly interpreting gestures or voice, the system uses EEG signals as a mediator to translate physiological responses into control commands, improving reliability by capturing objective physiological data rather than subjective external expressions.
2Measurement precision
If EEG detection is used to determine control information, then interpretation accuracy is improved, but system complexity increases
Solution Approach 1:
The patent extracts and utilizes only the relevant EEG detection information related to head motions, rather than processing all possible physiological signals. By selectively focusing on specific EEG patterns associated with head movements, the system achieves high interpretation accuracy while minimizing processing complexity and avoiding unnecessary system components.
3Adaptability or versatility
If head motion control is implemented, then interaction flexibility is improved, but detection difficulty increases
Solution Approach 1:
The patent replaces complex mechanical motion tracking systems with EEG-based detection. Instead of using cameras, accelerometers, or other mechanical sensing devices to track head movements, the system detects the physiological correlate of head motions through EEG signals, simplifying the detection mechanism while maintaining interaction flexibility.
