Vehicle Display Graphic Object Pivoting for Acceleration Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle information display systems fail to provide an adaptive and intuitive representation of the driving situation, lacking feedback to the driver through dynamic changes in graphical objects based on vehicle acceleration.
Innovation Solution
The method involves dynamically changing the representation of graphical objects on a vehicle's display device in response to detected acceleration, using three-dimensional perspective or autostereoscopic pivoting movements that align with the vehicle's acceleration axes, allowing for intuitive visualization of the driving situation without requiring special viewing aids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If static graphical objects are displayed on the vehicle display, then the display system is simple and easy to operate, but the driver receives no feedback on the driving situation
Solution Approach 1:
The patent applies dynamics by transforming static graphical objects into dynamic representations that pivot and change orientation based on detected vehicle acceleration. The graphical objects respond to acceleration inputs by rotating and repositioning themselves, providing real-time feedback on the driving situation without requiring complex additional hardware.
Solution Approach 2:
The patent implements feedback by using acceleration sensors to detect vehicle motion and automatically adjusting the graphical object representation accordingly. The system closes the feedback loop by taking sensor data about vehicle acceleration and using it to modify the display output, giving the driver intuitive visual feedback about the vehicle's dynamic state.
2Ease of operation
If traditional 2D display representations are used, then the display device is simple, but the driver lacks intuitive understanding of the driving situation
Solution Approach 1:
The patent applies dimensionality change by transitioning from flat 2D graphical representations to pseudo-3D representations that utilize depth perception through perspective projection. The graphical objects are rendered with three-dimensional properties and pivot in 3D space, creating a more intuitive visual experience that helps drivers understand the driving situation better.
Solution Approach 2:
The patent implements parameter changes by dynamically modifying multiple parameters of the graphical objects including their orientation, position, scale, and perspective based on acceleration sensor data. These parameter changes occur in real-time as the vehicle accelerates, providing intuitive visual feedback about the driving situation.
3Loss of information
If acceleration-based dynamic display changes are implemented, then intuitive feedback on driving situation is provided, but the processing requirements and system complexity increase
Solution Approach 1:
The patent uses an intermediary approach by introducing a control device that acts as a mediator between the acceleration sensor and the display device. This control device processes the acceleration data and generates appropriate graphical object transformations, simplifying the overall system architecture while still providing sophisticated dynamic feedback.
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
This approach provides the driver with real-time, intuitive feedback on the vehicle's acceleration and direction, enhancing situational awareness through adaptive and engaging graphical representations that align with the vehicle's movements, improving the overall driving experience.
Implementation Method 1
the acceleration of the vehicle is detected by means of an acceleration sensor
Implementation Method 2
the graphic object is displayed in three-dimensional perspective pivoted about an axis when the display is changed
Implementation Method 3
the graphic object is displayed autostereoscopically pivoted about an axis when the display is changed. In this case, in contrast to the perspective representation, one eye of the viewer sees a slightly different image than the other eye, so that a real three-dimensional representation is achieved
Implementation Method 4
The mask is a wavelength-selective filter mask, for example. This filter specifies the light propagation directions of the individual sub-pixels of the display by covering or filtering
