Dual Display Map and Panorama Control via Device Tilt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for displaying panoramic images corresponding to a position on a map often require a single screen, which limits user experience and visibility, as they cannot efficiently utilize two display devices to show different types of information simultaneously.
Innovation Solution
A display system comprising a first and second display device, along with a display control unit, that controls one device to display a map image and the other to show a partial panoramic image, allowing users to browse and interact with both images using two screens, with the ability to change the line of sight by tilting the terminal device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single display device is used to show panoramic images, then the device complexity is reduced, but the visibility and user experience deteriorate due to limited screen space
Solution Approach 1:
The patent combines multiple display devices (terminal device and car navigation system) to work together as an integrated display system. The terminal device displays map information while the car navigation system displays panoramic images, merging their display capabilities to provide comprehensive information without overwhelming a single device
Solution Approach 2:
The patent segments the display functionality across two devices: the terminal device handles map information display while the car navigation system handles panoramic image display. This segmentation allows each device to specialize in specific information types, improving overall visibility and user experience
2Loss of information
If different types of information are displayed on separate screens, then the information visibility is improved, but the ease of operation deteriorates due to needing to switch between devices
Solution Approach 1:
The system establishes bidirectional communication between the terminal device and car navigation system. When the user tilts the terminal device, the car navigation system detects this input and adjusts the panoramic image display accordingly, providing immediate feedback that maintains operational convenience while displaying information on separate screens
3Adaptability or versatility
If the panoramic image line of sight is changed by tilting the terminal device, then the adaptability is improved, but the measurement precision deteriorates due to difficulty in detecting device attitude
Solution Approach 1:
The patent introduces an intermediary detection mechanism that receives tilt input from the terminal device and translates it into line of sight adjustments for the panoramic image. This intermediary layer handles the complex conversion between physical tilt and virtual camera orientation, improving measurement precision while maintaining adaptability

AI summary
An exemplary display system includes: a first display device; a second display device; and a display control unit that controls one of the first display device and the second display device to display a map image corresponding to a given position, and controls the other of the first display device and the second display device to display a partial image which is a part of a panoramic image corresponding to the position.
