Blur Test for Vehicle GUI Readability Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for designing graphical user interfaces for vehicles are time-intensive and costly, as they require extensive testing on actual prototypes, which is inefficient and expensive.
Innovation Solution
A method involving a 'blur test' to validate GUI designs by simulating the driver's peripheral vision, where a blurred version of the design is tested for readability, allowing redesigns until it meets readability criteria before creating a prototype, focusing on increasing size, color contrast, and clarity of safety-related elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional prototype testing methods are used to validate GUI design, then design reliability is improved, but development time and cost increase significantly
Solution Approach 1:
The blur test is performed during the design phase before prototype creation, allowing designers to identify and fix readability issues early. This preliminary validation prevents the need for multiple expensive prototype iterations, thereby reducing overall development time while maintaining design reliability.
Solution Approach 2:
Instead of creating multiple physical prototypes for testing, the invention uses a simplified blur test copy or representation of the GUI design. This copying approach allows rapid validation of design concepts without the time and cost overhead of building and testing actual prototypes repeatedly.
2Manufacturing precision
If multiple prototypes are created for testing, then design accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The blur test validates design accuracy early in the design phase, identifying issues before prototype manufacturing begins. This preliminary check ensures design accuracy is achieved through low-cost design iterations rather than expensive prototype re-manufacturing.
Solution Approach 2:
The invention replaces expensive, long-lived physical prototypes with inexpensive, disposable blur test representations. These cheap test copies can be rapidly created and discarded, allowing multiple validation iterations without significant manufacturing cost.
3Reliability
If detailed design testing is performed early, then design quality is improved, but complexity of the testing process increases
Solution Approach 1:
The invention extracts the essential validation requirement from complex prototype testing processes. By isolating the critical readability assessment into a simple blur test, it maintains high design quality validation while eliminating the complexity of full prototype testing procedures.

AI summary
A method of validating a design for a graphical user interface of a motor vehicle includes creating a tentative design, and/or a few drafts or prototype for the graphical user interface. A blurred version of the tentative graphical user interface design is produced. The blurred version of the tentative graphical user interface design is tested for readability and whether the overall GUI design is suited to be perceived at a glance. If it is determined that the blurred version of the tentative graphical user interface design is not readable or understandable, then the graphical user interface is redesigned and the producing and testing steps are repeated for the redesigned graphical user interface. After the blurred graphical user interface design has been determined to be readable, then a higher fidelity graphical user interface is made.
