Minimally Intrusive Display for Eyewear Heart Rate Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports eyewear lacks minimally intrusive display systems that can provide real-time feedback and heart rate monitoring without obstructing the user's view or requiring them to stop their activity.
Innovation Solution
A minimally intrusive display system (MIDS) integrated into various types of eyewear, such as swim goggles and sunglasses, which includes sensors for heart rate monitoring and provides feedback through a small, peripheral display that only appears when the user looks at it, allowing for continuous monitoring and feedback during activities like swimming, running, and bicycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display system is integrated into sports eyewear to provide real-time feedback, then information availability is improved, but visual obstruction increases
Solution Approach 1:
The display system is positioned in the peripheral vision area of the eyewear rather than in the central visual field. This allows the display to provide real-time performance feedback while occupying only a small portion of the total visual area, thus resolving the contradiction between information availability and visual obstruction.
2Loss of information
If the display is always visible to provide continuous feedback, then information availability is improved, but user distraction increases
Solution Approach 1:
The display system dynamically adjusts its visibility based on user needs and activity context. The display can be configured to show information continuously, intermittently, or only upon specific triggers, allowing the system to provide continuous monitoring capability while minimizing distraction by adjusting the temporal and spatial presentation of information.
3Illumination intensity
If the display system is made larger to improve visibility, then information clarity is improved, but device intrusiveness increases
Solution Approach 1:
The display system concentrates visual output in a localized peripheral region rather than spreading it across the entire visual field. This allows the display to achieve sufficient visibility for performance feedback while maintaining a compact form factor that does not significantly increase eyewear intrusiveness or alter the overall device complexity.
Data Source
AI summary
A system includes a minimally intrusive display system (MIDS) configured to be disposed on an eyewear. The MIDS includes a display system and a sensor system configured to provide for a sensor data. The MIDS further includes a processor configured to process the sensor data to derive a physiological measure. The processor is further configured to display, via the display system, the physiological measure, wherein the display system is disposed in the eyewear so that the physiological measure is only viewed when a user of the eyewear turns the user's pupil towards the display system at angle α from a forward direction.
