Synchronized Eyewear for Multi-Channel Display Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display techniques, such as split screens, are limited in presenting multiple channels simultaneously and fail to provide privacy for individual viewers, as they typically require equal-sized viewing areas and do not allow for selective viewing.
Innovation Solution
A system comprising eyewear devices and a processor that synchronizes the operation of eyewear with a common display to allow multiple users to view different images sequentially, using time-division multiplexing and polarization techniques to privatize channels for individual viewers while presenting a neutral screen to onlookers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If split screen display is used to present multiple channels simultaneously, then multiple viewing areas are provided, but the viewing areas are limited in size and cannot be selectively viewed by individual users
Solution Approach 1:
The display system segments the viewing experience by assigning different image channels to different users through synchronized eyewear devices. Each user receives a dedicated full-resolution image stream while sharing a common display, effectively dividing the viewing content without reducing individual viewing area quality
Solution Approach 2:
The invention adds a temporal dimension to the display system by using time-division multiplexing. Images are displayed in rapid succession across multiple channels, and the synchronized eyewear filters these channels temporally to deliver separate full-resolution images to different users simultaneously
2Object-affected harmful factors
If privacy filters are positioned in front of a monitor to make information visible only to a particular viewer, then viewing privacy is provided, but the display cannot serve multiple users with different content simultaneously
Solution Approach 1:
The common display serves multiple functions by presenting different image channels sequentially that are selectively viewed by different users wearing synchronized eyewear. The same physical display adapts to serve multiple users with different content needs simultaneously, replacing the need for multiple separate displays or privacy filters
Solution Approach 2:
The system dynamically switches between different image channels in rapid succession, with the eyewear synchronization ensuring each user sees only their assigned content. This dynamic temporal multiplexing provides privacy while maintaining multi-user versatility
3Quantity of substance
If multiple full-resolution channels are displayed sequentially on a common display, then private viewing for multiple users is enabled, but synchronization between display and eyewear is required
Solution Approach 1:
The system uses feedback mechanisms where the display and eyewear devices communicate to maintain synchronization. The processor coordinates the timing of image channel display with the eyewear's active periods, ensuring each user receives their designated content at the correct moments

AI summary
Methods and apparatus for rendering plural channels on a common display are provided. In a method embodiment, a method for allowing sharing of a display by a plurality of users wishing to view a plurality of respective images includes displaying the plurality of respective images sequentially on the display. The method further includes selectively allowing the respective image to be viewed by the respective user, but not by any other of the plurality of users.
