In-Vehicle App Display With Switchable Full-Screen Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-vehicle systems, such as HiCar, cannot fully occupy the head unit screen, limiting user interaction and experience when extending mobile phone applications to vehicles.
Innovation Solution
A display method that allows users to operate the head unit to display application interfaces in full screen by hiding the navigation bar upon user input, enabling customizable full-screen or non-full-screen modes through specific operations, such as gestures or voice commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the navigation bar is displayed to provide navigation controls and information, then the ease of operation is improved, but the area available for application display is reduced
Solution Approach 1:
The navigation bar is designed to be dynamically adjustable between displayed and hidden states. Users can switch between full-screen mode (hiding navigation bar) and controlled mode (showing navigation bar) based on their immediate needs, allowing the interface to adapt to different usage scenarios
2Area of stationary object
If the application interface is displayed in full screen to maximize display area, then the area of stationary object is improved, but the ease of operation deteriorates due to loss of navigation controls
Solution Approach 1:
The system provides dynamic switching between full-screen display mode and controlled display mode. Users can toggle the navigation bar visibility according to their needs, enabling full-screen immersion when navigation is not required and controlled access when navigation controls are needed
3Area of stationary object
If the navigation bar is permanently hidden to maximize application display area, then the area of stationary object is improved, but the adaptability deteriorates as users cannot access navigation controls when needed
Solution Approach 1:
The navigation bar implements dynamic visibility control where users can switch between hidden and displayed states. This allows the system to adapt to different user preferences and usage scenarios, providing both full-screen experience and navigation control access as needed
Solution Approach 2:
The system changes the visibility parameter of the navigation bar based on user input. By toggling this parameter between visible and hidden states, the system provides different display modes (full-screen vs. controlled) to accommodate various user needs and scenarios

AI summary
A display method includes sending, by a first electronic device, information about a first application to a second electronic device; displaying, by the second electronic device, an icon of the first application on a display in response to the received information about the first application; in response to an operation performed by a user on the icon of the first application on the second electronic device, displaying, by the second electronic device, a navigation bar in a first region of the display and displaying a first interface of the first application in a second region of the display; detecting a first operation performed on the second electronic device; and hiding, by the second electronic device, the navigation bar and displaying the first interface of the first application in full screen.
