Coordinated Scrolling of 3D and 2D Display Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for scrolling two-dimensional images on touch panels do not account for the display of virtual three-dimensional space images or the simultaneous display of both two-dimensional and three-dimensional images on a single screen, leading to suboptimal user convenience and operability.
Innovation Solution
A computer-readable storage medium with an information processing program that enables screen scroll control by positioning objects in a virtual three-dimensional space, using a virtual camera to generate three-dimensional images, and displaying both three-dimensional and two-dimensional images on a single screen, allowing for intuitive operability and effective use of screen space through coordinated scrolling and zooming based on user input.

Engineering Contradiction Analysis
1Loss of information
If a two-dimensional image and a virtual three-dimensional space image are simultaneously displayed on a single screen, then the information display capability is improved, but the operability and user convenience deteriorate due to lack of coordinated scroll control
Solution Approach 1:
The screen is divided into a content display area and a menu display area, with further segmentation of the content display area into a three-dimensional image display region and a two-dimensional image display region. This segmentation allows independent control and optimization of each region's functionality and display characteristics, resolving the conflict between displaying multiple image types and maintaining ease of operation.
Solution Approach 2:
The patent implements dynamic scroll control where the scroll behavior adapts based on the type of image being displayed. When the three-dimensional image display region is active, scrolling controls the virtual camera position; when the two-dimensional image display region is active, scrolling moves the content display area. This dynamic adjustment maintains operability while displaying multiple image types simultaneously.
2Ease of operation
If the content display area is scrolled on the screen, then the two-dimensional image area can be navigated, but the three-dimensional image area may lose its optimal viewing position
Solution Approach 1:
The scroll control system dynamically adjusts its behavior based on which image type is currently active. When the two-dimensional image area is the focus, the entire content display area scrolls to enable navigation. When the three-dimensional image area is active, only the virtual camera position changes while the content display area remains stationary, preserving the three-dimensional image's optimal viewing position.
Solution Approach 2:
Different scroll behaviors are applied to different regions based on their specific requirements. The two-dimensional image region benefits from full content display area scrolling for navigation, while the three-dimensional image region maintains its position with only camera movement, ensuring each region receives the appropriate scroll control for its optimal functionality.
3Measurement precision
If the three-dimensional image area is enlarged, then the viewing detail is improved, but the screen space for two-dimensional image display is reduced
Solution Approach 1:
The display system dynamically adjusts the size and visibility of different image regions based on user interaction. When the three-dimensional image area is enlarged for detailed viewing, the two-dimensional image display area automatically adjusts its size and position. This dynamic redistribution of screen space allows temporary enhancement of three-dimensional image detail while maintaining overall screen utilization.
Solution Approach 2:
The patent utilizes the spatial arrangement in another dimension by positioning the three-dimensional and two-dimensional image areas in different regions of the screen. When one area is enlarged, the other can be repositioned or resized in the remaining space, effectively using the two-dimensional screen real estate to accommodate both image types at different scales simultaneously.

AI summary
A content display area that is an area where screen scroll is possible on the basis of an input performed with a pointing device and includes a three-dimensional image area for projecting a three-dimensional image and a two-dimensional image area for displaying a two-dimensional image, the two-dimensional image area being adjacent to the three-dimensional image area, is displayed on a screen. Then, when the content display area is scrolled on the screen, both the three-dimensional image area and the two-dimensional image area are scrolled on the screen together.
