Remote Presentation Highlighter Using Digital Region Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for highlighting and magnifying content on a presentation screen, such as using handheld laser pointers, are inadequate for making small text, numbers, and details visible, especially in remote viewing scenarios, and can create glare on television screens.
Innovation Solution
A system comprising a primary electronic device for generating a presentation and a secondary device, such as a mobile device with a camera, that identifies and transmits a highlighted portion of the presentation for enhancement, allowing for remote magnification, color change, outlining, or contrast adjustment on the presentation screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a laser pointer is used to highlight content on a presentation screen, then the presenter can remotely point to specific areas, but the highlighted content remains difficult to see clearly and small text/details remain invisible
Solution Approach 1:
The system creates a digital copy of the highlighted region from the presentation source, processes it separately, and sends it back to the display device. This allows the highlighted content to be enhanced (magnified, recolored, outlined) in the digital domain before being displayed, solving the visibility problem while maintaining remote highlighting capability
Solution Approach 2:
The invention transitions from direct optical highlighting (2D screen surface) to multi-dimensional processing by capturing the highlight coordinates, retrieving the corresponding image data, applying enhancements in the digital domain, and redisplaying it. This dimensional transition enables both remote control and enhanced visibility
2Ease of operation
If a laser pointer is used on a television screen to highlight content, then remote pointing is achieved, but glare is created on the screen
Solution Approach 1:
The system introduces a digital intermediary process between the laser pointer and the screen. Instead of directly shining light on the screen, the laser pointer sends coordinate data to the presentation device, which then retrieves and processes the corresponding image region, and finally displays it back. This intermediary digital processing eliminates the need for direct optical interaction with the screen, preventing glare
Solution Approach 2:
The invention replaces the optical-mechanical laser pointer system with a digital data transmission system. The physical laser beam is substituted by electronic coordinate transmission, image data retrieval, digital processing, and electronic redisplay, eliminating the harmful optical reflection while preserving the remote pointing function
3Area of stationary object
If the entire presentation is displayed at normal size, then all content is visible, but small text, numbers, and details cannot be seen clearly
Solution Approach 1:
The system segments the presentation into distinct regions, allowing the presenter to highlight a specific segment. The highlighted segment is then separately processed (magnified, enhanced) and displayed while the rest of the presentation remains in its original context. This segmentation enables simultaneous visibility of both overall layout and detailed content
Solution Approach 2:
The invention applies local quality enhancement by magnifying and enhancing only the highlighted region while keeping the rest of the presentation at normal size. This allows viewers to see both the overall presentation context and the enhanced details of the specific region, solving the contradiction between overall visibility and detail visibility
Data Source
AI summary
A device, system and method for highlighting a portion of a displayed presentation. The invention includes a presentation device for generating a presentation for remote display; and an electronic pointer device for identifying a portion of the presentation for highlighting and for transmitting the identified portion of the presentation to the presentation device. The presentation device is then able, after receiving the transmitted identified portion of the presentation, to generate an enhanced copy of the identified portion on the remote display as part of the presentation. The enhanced copy of the identified portion on the remote display is magnified, colored, outlined or otherwise converted to contrast with the remainder of the presentation.
