Pointing-Based Display Area Switching for Large Whiteboard Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic whiteboards struggle to display large content fully due to display size and resolution limitations, making it difficult to view detailed parts of a region without reducing the image size or moving the display area with swiping, which can be cumbersome for participants.
Innovation Solution
A device that detects pointing coordinates outside the display area and switches the display area to include the desired region, allowing users to gesture-point to areas outside the display for seamless enlargement without resizing or swiping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the entirety of large-size content is displayed on the display device, then the content can be viewed in full, but the displayed content becomes exceedingly small and difficult to see due to display size and resolution limitations
Solution Approach 1:
The patent divides the large content into multiple regions and displays only the necessary portion on the display device. When a user points to a specific region outside the current display area, the system segments the content and switches to displaying that specific region, allowing detailed viewing without requiring the entire content to fit on the display screen.
Solution Approach 2:
The patent introduces a virtual dimension by detecting pointing coordinates outside the physical display area. This allows users to access content regions that extend beyond the display boundaries, effectively adding a virtual extension to the display space without physically enlarging the display device.
2Ease of operation
If the display area is switched by swiping operation, then the desired region can be displayed, but the operation becomes cumbersome for participants
Solution Approach 1:
The patent replaces the mechanical swiping gesture with a pointing gesture. Instead of requiring users to physically swipe across the display surface to navigate between regions, users simply point with a pointing object (such as a pen or finger) at the desired region, and the system automatically switches the display area based on the detected pointing coordinates.
Solution Approach 2:
The system automatically determines which region to display based on the pointing coordinates without requiring users to perform complex navigation operations. The display area switching is performed autonomously by the system in response to the pointing gesture, reducing the operational burden on participants.
3Area of stationary object
If the image size is reduced to fit the display area, then the entire content can be displayed, but the detailed parts of the region become difficult to view
Solution Approach 1:
The patent implements dynamic display area switching based on user interaction. The display area is not fixed but can be dynamically adjusted in response to pointing gestures. When users point to specific regions, the display area dynamically switches to show that region in detail, allowing high-quality viewing of detailed parts while maintaining the ability to display the entire content when needed.
Data Source
AI summary
A device includes circuitry to detect coordinates of a position pointed to by a pointing object, and control a display to display a part of a region where a content having the coordinates is present in a case that the coordinates are outside a display area of the display and within the region of the content.
