Guide Display Device Screen Orientation Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hands-free devices for drivers require multiple procedures for making calls, which can be cumbersome and distract from driving, and there is a need to simplify these operations while ensuring safety.
Innovation Solution
A guide display device and method that detects screen orientation changes and displays necessary information, such as destination details or navigation, when close to the destination, and integrates with external equipment like portable phones for simplified hands-free operation by displaying relevant information, like a keyboard, only when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple procedures are required for hands-free operation, then calling functionality is achieved, but driver burden increases and safety decreases
Solution Approach 1:
The system performs preliminary actions by detecting screen arrangement changes and automatically displaying relevant information (destination details, keyboard) in advance of the driver's need, eliminating the need for manual navigation through multiple menus and procedures during critical driving moments
Solution Approach 2:
The hands-free device serves itself by automatically detecting when the screen arrangement changes and autonomously displaying the appropriate information without requiring driver intervention to navigate menus or initiate displays, thereby reducing operational steps while maintaining full functionality
2Loss of information
If detailed information is always displayed, then user needs are met, but driver distraction increases
Solution Approach 1:
The display system dynamically adjusts its behavior based on screen arrangement state, automatically switching between displaying detailed destination information and minimizing distractions, thereby adapting to different driving contexts without manual intervention
Solution Approach 2:
The system changes display parameters (information visibility, keyboard display) based on the detected screen arrangement state, ensuring that detailed information is presented only when appropriate (when screen arrangement changes indicate the driver is not actively viewing), thus balancing information completeness with driver safety

AI summary
The present invention provides the simple operation for displaying the information that is expected to be necessary for the user and the simplified procedure of the hands-free operation when displaying the map information on the screen. The display device 20 in which an arrangement state of the screen can be selected between a first state and a second state displays on the screen the detailed information of a destination or its surrounding area such as parking lot information, an access route guide to the transportation facilities, and information of the facility of the destination is displayed on the screen if a change of the arrangement of the screen is detected, if the destination has been set in advance, and if a distance between a current position and the destination is within a predetermined distance. Further, it comprises a display control means 27 for displaying at least a portion of the information acquired by the information acquisition means 23 if the change in the arrangement state of the screen is detected after the external equipment detection means 25 detected the connection of the external equipment 4.
