Wearable Driver Display for Vehicle Environment Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems in motor vehicles often require the driver to divert their gaze from the road to view environment data displayed on fixed dashboard screens, particularly during reversing or parking, which can be inconvenient and unsafe.
Innovation Solution
A wearable apparatus with a communication device, display device, and processor that receives environmental data from the vehicle and displays it on a wrist-worn smartwatch or arm-mounted display, allowing the driver to view critical information without looking away from the driving direction, with options to selectively display rear, front, or lateral environments based on driving direction and user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If environment data is displayed on a fixed dashboard display device, then the driver can access environment data, but the driver must divert gaze from the road especially during reversing
Solution Approach 1:
The display device is moved from the fixed dashboard position to a wearable apparatus that can be positioned in multiple locations (wrist, arm, or head-mounted), adding spatial flexibility to the display system and allowing the driver to view environment data within their existing field of view
Solution Approach 2:
The wearable display device can be dynamically positioned and adjusted by the driver according to their viewing needs and driving situation, transforming from a static dashboard display to a dynamic, adaptable display solution
2Adaptability or versatility
If the driver changes viewing direction during reversing, then the driver can see rear environment, but fixed display device lies outside field of view
Solution Approach 1:
The display is relocated from the fixed dashboard plane to wearable positions that can be integrated into the driver's natural viewing geometry, allowing environment data to remain visible regardless of head or body orientation during reversing maneuvers
3Ease of operation
If environment data is displayed on wearable apparatus, then data remains within driver's field of view, but requires wireless communication and portable power
Solution Approach 1:
A wireless communication interface acts as an intermediary between the vehicle's sensor systems and the wearable display, enabling data transfer without physical connections and reducing the complexity of wired integration
Solution Approach 2:
The wearable apparatus serves multiple functions: displaying environment data, providing portable power through integrated battery, and enabling wireless communication, consolidating what would otherwise be separate systems into a single multi-functional device

AI summary
A wearable apparatus for use by a driver of a motor vehicle is provided. The apparatus comprises a communication device which is configured to communicate with a complementary communication device of the motor vehicle. The apparatus further comprises a display device and a processor device. The processor device is configured to receive, via the communication device, sensor-acquired data regarding an environment of the motor vehicle from the complementary communication device of the motor vehicle and to control the display device to display the received environment data or environment data derived therefrom.
