Solution Overview
Problem
Conventional wearable devices require user interaction to access biometric data, disrupting physical activities and hindering performance improvement.
Innovation Solution
A head-worn wearable device coordinates sensor data display through an LED without a heads-up display, using physiological-based thresholds to illuminate variable light patterns based on biometric and other sensor data, allowing users to monitor their performance without distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional wearable devices are used to display biometric data, then users can access their performance information, but users must interrupt or pause their physical activity to review the data
Solution Approach 1:
The patent replaces the mechanical interaction system (requiring users to physically interact with devices to access data) with an optical communication system using LEDs. The head-worn device displays biometric information through illuminated patterns that can be perceived without physical interaction, allowing users to monitor their workout in real-time without pausing or diverting attention from the activity.
Solution Approach 2:
The patent introduces an intermediary communication channel between the biometric sensor and the user. Instead of directly displaying data on a traditional screen that requires attention, the system uses light patterns as an intermediary medium to convey biometric information subconsciously or peripherally, eliminating the need for users to actively seek out and interpret data displays.
2Loss of information
If conventional wearable devices with displays are used, then users can view biometric data, but users must physically interact with the device to access information
Solution Approach 1:
The system performs self-service by automatically interpreting and displaying biometric data without requiring user initiation. The head-worn device continuously monitors physiological parameters and autonomously translates them into visual light patterns, eliminating the need for users to press buttons, swipe screens, or otherwise physically interact with the device to access their performance information.
Solution Approach 2:
The patent replaces the mechanical interaction system (requiring users to physically interact with devices to access data) with an optical communication system using LEDs. The head-worn device displays biometric information through illuminated patterns that can be perceived without physical interaction, allowing users to monitor their workout in real-time without pausing or diverting attention from the activity.
3Loss of information
If heads-up display or overhead display is used to show sensor data, then users can view information during activity, but the display may obstruct the user's view
Solution Approach 1:
The patent applies local quality by using multiple LEDs positioned at different locations on the head-worn device, each displaying specific biometric information. The light patterns are distributed across different spatial zones, allowing users to perceive various types of feedback (heart rate, pace, posture) at different locations without any single display obstructing their view of the environment ahead.
Solution Approach 2:
The system segments the information display function across multiple spatially separated LEDs rather than using a single consolidated display. Each LED or group of LEDs handles specific data types, distributing the visual information load across different locations on the device perimeter, thereby maintaining clear visibility of the user's path forward while providing comprehensive biometric feedback.

AI summary
Methods and systems of coordinating display of biometric data at a head-worn wearable device based on sensor data from a wrist-wearable device are disclosed. A method includes receiving an indication that a user of a head-worn wearable device is performing a physical activity. The head-worn wearable device includes a light-emitting diode visible to the user while wearing the head-worn wearable device and is in communication with a wrist-wearable device worn by the user. The wrist-wearable device is configured to sense biometric data for the user during the physical activity. The method includes, after receiving the indication and while the user is performing the activity, in accordance with a determination that the biometric data satisfies a physiological-based threshold indicating that information about the biometric data would assist the user in performing the physical activity, causing the head-worn wearable device to present, via the light-emitting diode, the information about the biometric data.
