Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Extended reality devices are unable to utilize biometric data collected by wearable devices to update the extended reality environment, limiting the user's experience.
Innovation Solution
Wearable devices establish a wireless connection with user devices and extended reality devices to send biometric data, allowing the extended reality device to provide visual, audio, and/or haptic feedback based on the collected data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If wearable devices collect biometric data, then data availability is improved, but the extended reality device cannot utilize the data effectively
Solution Approach 1:
The system implements a feedback loop where biometric data from wearable devices is continuously transmitted to the extended reality device, which then adjusts the virtual environment in real-time based on the user's physiological state. This closed-loop feedback mechanism enables the extended reality system to adapt to user needs dynamically, resolving the contradiction between data availability and effective utilization.
Solution Approach 2:
The extended reality device is designed to handle multiple data types (biometric, motion, environmental) and provide multiple functions (visual feedback, audio feedback, haptic feedback, environment adjustment) through a unified system. This multi-functionality allows the device to effectively utilize various biometric data streams for different purposes, improving both data utilization and system adaptability.
2Ease of operation
If the extended reality device provides personalized feedback based on biometric data, then user experience is improved, but system complexity increases
Solution Approach 1:
The system introduces intermediate processing layers including wireless communication modules and data processing algorithms that act as mediators between the wearable devices and the extended reality device. These intermediaries handle data transmission, filtering, and preliminary analysis, reducing the computational burden on the main extended reality system while enabling sophisticated personalized feedback without proportionally increasing overall system complexity.
3Speed
If the extended reality device uses biometric data to update the environment in real-time, then responsiveness is improved, but data processing requirements increase
Solution Approach 1:
The system implements selective processing where only relevant biometric parameters are processed at high frequency for real-time environment updates, while other parameters are processed at lower frequencies or aggregated over time. This partial action approach maintains responsiveness for critical parameters (such as heart rate for intensity adjustment) while reducing overall processing energy requirements by avoiding unnecessary high-frequency processing of all available data streams.

AI summary
Methods, systems, and devices for a wearable device are described. An extended reality device may establish a connection with a wearable device, such as directly with the wearable device or via a user device connected with the wearable device. The extended reality device may acquire biometric data from sensors of the wearable device, the biometric data for a user of the extended reality device and the wearable device. The extended reality device may provide feedback to the user by updating an extended reality environment, an extended reality experience, or both. For example, the extended reality device may provide visual feedback, audio feedback, haptic feedback, or any combination thereof.
