Touch Screen Display Repositioning for Speaker-Blocked Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large touch screens obstruct audience members' view of the content when the speaker is in front of the screen, leading to a suboptimal viewing experience and information reception.
Innovation Solution
A touch screen system that uses a camera to detect the speaker's position and dynamically adjusts the display to show blocked content in unobstructed areas using picture-in-picture technology, maintaining the aspect ratio and filling the unblocked area with screen content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the speaker stands in front of the large touch screen to present, then the speaker can operate the screen directly, but the speaker's body obstructs the view of the content for some audience members
Solution Approach 1:
The screen is divided into multiple display areas, with the main content displayed on the primary screen and the blocked content displayed in a separate picture-in-picture window. This segmentation allows the speaker to operate the main screen while audience members can see both the speaker and the content simultaneously through the divided display areas.
Solution Approach 2:
The solution transitions from a two-dimensional flat display to a multi-layered display by adding a picture-in-picture window that overlays additional content. This dimensional change allows multiple pieces of information (speaker view and screen content) to be displayed simultaneously without obstructing each other.
2Loss of information
If an additional display device is provided to show blocked content, then audience members can see the content, but the cost and space requirements increase
Solution Approach 1:
The large touch screen performs multiple functions: it serves as both the main display for content and the picture-in-picture display for blocked content. This multi-functionality eliminates the need for additional display devices, reducing both cost and space requirements while maintaining the ability to show blocked content to audience members.
Solution Approach 2:
The solution merges the main content display and the blocked content display into a single integrated system. The picture-in-picture technology combines multiple video streams into one display device, allowing the touch screen to simultaneously present both the speaker's view and the original content without requiring separate display equipment.

AI summary
A touch screen includes a power supply unit, configured to supply power; an image capturing unit, configured to capture images; a storage unit, configured to temporarily store screen content; an image display unit, configured to display the screen content; and a processing unit, coupled to the power supply unit, the image capturing unit, the storage unit, and the image display unit, configured to execute an image display method. The image display method includes capturing an image of an area in front of the touch screen; determining a position of a speaker according to the image, and determining a blocked area and an unblocked area according to the position; and displaying screen content related to the blocked area in the unblocked area.
