Adaptive Vehicle UI Layout Prioritizing Frequent Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted navigation systems do not adequately improve the ease of use of user interface elements during travel, as they maintain the same basic layout and disable operations without considering display constraints to enhance usability.
Innovation Solution
An information displaying device that evaluates the movement state of a vehicle and dynamically generates screen information by prioritizing frequently used UI elements during travel, displaying them in a layout that simplifies operations and reduces text amount, while allowing more elements to be displayed when instructed by the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the basic layout is maintained during travel with operations disabled, then display constraints are complied with, but ease of use deteriorates
Solution Approach 1:
The patent applies dynamics by making the UI layout adaptable rather than static. The system dynamically switches between a full layout and a limited layout based on vehicle travel state. During travel, frequently used UI elements are prioritized and repositioned in the limited layout, while less frequent elements are hidden or disabled. This dynamic adaptation maintains compliance with display constraints during travel while preserving ease of use for critical functions.
2Reliability
If only selectable items are limited in limited display mode, then display constraints are partially met, but ease of use remains unchanged and does not improve
Solution Approach 1:
The patent applies local quality by differentiating the treatment of UI elements based on their usage frequency and importance. Instead of uniformly limiting all UI elements, the system identifies frequently used elements and gives them priority placement in the limited layout during travel. Less frequently used elements are hidden or disabled. This selective, localized optimization improves ease of use for critical functions while maintaining compliance with display constraints.
3Device complexity
If the same layout is used regardless of travel state, then device complexity is reduced, but ease of use deteriorates during travel
Solution Approach 1:
The patent applies universality by creating a multi-functional layout system that adapts to different travel states. The same UI framework serves multiple purposes: displaying the full layout when the vehicle is stationary and displaying a optimized limited layout during travel. The system universally handles both states through a single adaptive mechanism, avoiding the need for completely separate UI systems while improving ease of use during travel.

AI summary
An information displaying device comprises: an input unit that receives operations from a user; a movement state evaluating unit that evaluates a state of movement of the mobile entity; a display information generating unit that generates screen information including UI elements (user interface elements) to be displayed on a display, based on a layout selected from layouts according to the evaluated state of movement of the mobile entity; and an operation detecting unit that detects the operations on each of the UI elements, and counts frequency of the operations on each of the UI elements while the movement state evaluating unit evaluates that the mobile entity is traveling; wherein, in the screen information based on the layout selected when the mobile entity is traveling, the UI elements with higher frequencies of the operations, which are detected by the operation detecting unit, are preferentially displayed on the screen of the display.
