Smart Ring Projection Module for In-View Driving Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle information systems provide limited and distracting information to drivers, often requiring them to take their hands off the wheel or gaze away from the road, which can lead to hazardous driving conditions.
Innovation Solution
A smart ring wearable device that projects vital driving conditions, biometric data, and environmental information onto a surface within the driver's field of view, allowing for hands-free and gaze-free access to critical information, including speed, weather, driver state, and vehicle status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is displayed on a console display within the vehicle, then the driver can access vehicle operational information, but the driver must take hands off the steering wheel or gaze away from the road
Solution Approach 1:
The patent transitions the display from a traditional 2D console screen to a 3D spatial projection in the driver's peripheral vision field. The projector module projects information onto a surface (such as the windshield or a floating display) that appears within the driver's natural field of view, eliminating the need to shift gaze or remove hands from the steering wheel while maintaining information accessibility.
Solution Approach 2:
The patent introduces a projector module as an intermediary device that bridges the gap between the driver and the information display. Instead of directly viewing a console display, the driver receives projected visual information through this intermediary, which delivers data to the peripheral vision field without requiring physical interaction or gaze diversion.
2Reliability
If a smart ring device projects information onto a surface within the driver's field of view, then the driver can access information without diverting attention from the road, but the device complexity increases
Solution Approach 1:
The smart ring device integrates multiple functions into a single wearable unit: biometric sensing (heart rate, stress, fatigue detection), communication (wireless connectivity to vehicle systems), and projection (visual information display). This multi-functionality consolidates what would otherwise require separate devices, managing complexity through integration rather than proliferation of components.
Solution Approach 2:
The smart ring device autonomously monitors driver biometrics, processes the data, and triggers appropriate visual alerts or information projection without requiring manual intervention. The device self-regulates by detecting driver state (e.g., fatigue, stress) and automatically adjusting the type and timing of information presented, reducing the need for complex control interfaces.

Data Source
AI summary
A system for displaying information indicative of driving conditions, to a driver, using a smart ring are disclosed. An exemplary system includes a smart ring with a ring band having a plurality of surfaces including an inner surface, an outer surface, a first side surface, and a second side surface. The system further includes a processor, configured to obtain data from a communication module within the ring band, or from one or more sensors disposed within the ring band. The obtained data are representative of information indicative of one or more driving conditions to be displayed to the driver. The smart ring also includes a projector module display disposed on at least one of the plurality of surfaces, and configured to present information indicative of the one or more driving conditions.
