Vehicle Heads-Up Display With Steering Wheel Tactile Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems fail to effectively minimize visual, manual, and cognitive distractions for drivers using mobile devices while driving, leading to accidents due to the need for drivers to interact with screens and input devices directly.
Innovation Solution
A vehicle heads-up display system comprising a display assembly with a combiner glass and a tactile input device mounted on the steering wheel, allowing drivers to interact with a mobile device through a touch-sensitive input device that communicates wirelessly, enabling control of the device without direct visual or manual interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If drivers directly interact with mobile device screens and input devices, then complete control and access to device functions is achieved, but visual, manual, and cognitive distractions increase
Solution Approach 1:
The system divides the mobile device control functionality into separate components: a display assembly mounted on the windshield for visual information, and a tactile input device mounted on the steering wheel for control inputs. This segmentation allows the driver to access device functions without directly interacting with the mobile device screen, reducing visual and manual distraction while maintaining operational capability.
Solution Approach 2:
The patent introduces intermediary devices between the driver and the mobile device: the display assembly acts as an intermediary for presenting information, and the tactile input device serves as an intermediary for transmitting control commands. These intermediaries enable driver control of the mobile device while keeping the driver's attention on the road, effectively mediating the interaction to reduce distraction.
2Ease of operation
If tactile input devices are integrated into steering wheels, then manual control is maintained, but device complexity increases
Solution Approach 1:
The tactile input device acts as an intermediary between the driver and the mobile device, mounted on the steering wheel to maintain manual control capability. While this adds components to the system, the intermediary approach consolidates control functions in a single location, potentially reducing overall system complexity compared to having separate control mechanisms for steering and device operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system minimizes visual, manual, and cognitive distractions by projecting essential information onto the windshield and allowing drivers to control their mobile devices using a tactile input device, reducing the need to look away from the road or remove their hands from the wheel.
Implementation Method 1
a combiner glass (e.g., half reflective mirror) that presents a display

AI summary
Provided is a heads up display system having a platform having a receiver configured to removably receive and physically support a mobile phone and/or tablet having a display screen, a medium oriented at an angle with respect to the platform, and an opening defined in the platform between the receiver and the medium. The system may include a couple configured to couple the platform to a structure or surface. The coupler can be configured to enable the platform to be coupled to the surface or structure at a selected angle.
