Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If neuroscience studies are conducted in controlled laboratory environments, then measurement precision is improved, but adaptability to different settings deteriorates
Solution Approach 1:
The patent introduces an extended reality (XR) system as an intermediary environment that creates a controlled virtual space within various physical settings. This XR environment serves as a mediator that maintains standardized experimental conditions (lighting, noise control, spatial configuration) while allowing the study to be conducted in different locations. The brain interface system synchronizes with the XR system to ensure precise measurement of neural responses to standardized stimuli, thus preserving measurement precision while enabling adaptability to different physical environments.
Solution Approach 2:
The patent creates a virtual copy of a controlled laboratory environment through the extended reality system. This digital replica reproduces the standardized lighting, acoustic properties, and spatial arrangement of a traditional lab setting, allowing researchers to conduct studies in diverse physical locations while maintaining the measurement precision associated with controlled environments. The virtual environment is synchronized with the brain interface system to ensure accurate temporal and spatial correspondence between stimuli and neural measurements.
2Reliability
If standardized task design and hardware calibration are implemented, then replicability is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal synchronization protocol that enables the brain interface system and extended reality system to communicate and coordinate their operations through standardized timing signals and data formats. This universal interface layer allows different hardware configurations to be calibrated and synchronized through a common framework, improving replicability across studies while managing device complexity through standardization. The synchronization mechanism ensures that stimuli presentation, neural measurement, and data recording are temporally aligned across different experimental setups.
3Loss of information
If extended reality system and brain interface system are synchronized, then loss of information is reduced, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical or manual synchronization methods with an electronic/digital synchronization system. The extended reality system generates timing signals that are electronically transmitted to and synchronized with the brain interface system through digital communication protocols. This substitution of electronic synchronization for mechanical coordination reduces information loss about temporal associations between stimuli and neural responses while managing the complexity through software-based solutions rather than complex hardware interconnections.
Data Source
AI summary
An illustrative system includes an extended reality system and a brain interface system configured to be concurrently worn by a user. The extended reality system is configured to provide the user with an extended reality experience and output a timing signal while the extended reality experience is being provided to the user, the timing signal representing a plurality of timing events that occur during the extended reality experience. The brain interface system is configured to receive the timing signal from the extended reality system while the extended reality experience is being provided to the user, acquire brain activity measurements while the extended reality experience is being provided to the user, and output measurement timestamp data representative of a temporal association of the brain activity measurements with the timing events.
