Quick Search Overlay for Vehicle Navigation Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional path display terminals require users to switch screens when inputting a destination, preventing them from viewing the vehicle's position and surrounding map simultaneously, especially in congested areas where quick searches are needed.
Innovation Solution
A quick search device for path display terminals that allows users to input destinations while viewing their vehicle's position on a map, with a transparent quick search area that converts to a button when necessary, and automatically selects search methods based on input formats, ensuring uninterrupted map viewing even at low speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional path display terminal converts the vehicle surrounding map screen to a destination input screen when the user inputs a search word, then the user can input the destination, but the user cannot view the vehicle position and surrounding map simultaneously
Solution Approach 1:
The terminal screen is segmented into multiple display regions: a map display region showing the vehicle position and surrounding area, and a quick search area overlaying part of the map. This segmentation allows simultaneous display of map information and destination input interface, resolving the contradiction between destination input capability and map visibility.
Solution Approach 2:
The quick search area is implemented as a transparent or semi-transparent overlay on top of the map display, adding a new display dimension. This allows the destination input interface to coexist with the map display in the same screen space, enabling users to input destinations while continuously viewing the vehicle position and surrounding map.
2Ease of operation
If the quick search area is displayed as an opaque overlay, then the user can easily input the destination, but the path information may be hidden when the vehicle advances along the path
Solution Approach 1:
The quick search area dynamically changes its transparency or visibility based on the vehicle's movement state. When the vehicle is stationary or moving slowly, the quick search area remains visible for easy destination input. When the vehicle advances along the path, the quick search area becomes transparent or converts to a button, ensuring path information remains visible. This dynamic adjustment resolves the contradiction between input visibility and path information visibility.
Solution Approach 2:
The display parameters of the quick search area (transparency, visibility, form) are changed based on vehicle movement conditions. The system monitors vehicle speed and position, and adjusts the quick search area's display properties accordingly - maintaining high visibility during stationary input phases and reducing visibility during movement phases when path information is more critical.
3Ease of operation
If the quick search area remains visible at all times, then the user can continuously access destination input, but the user cannot view a wide range of map at one time when the vehicle is driven at high speed
Solution Approach 1:
The quick search area's visibility and position are dynamically adjusted based on vehicle speed. At low speeds, the quick search area is prominently displayed for easy destination input. At high speeds, the quick search area becomes transparent or relocates to minimize obstruction of the map viewing area, allowing users to view a wider range of the map while maintaining the ability to access destination input functionality when needed.
