Presenter Superimposition in Web Conferencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current web conferencing systems fail to replicate the immersive experience of an in-person presentation for remote participants, as they typically display the presenter and presentation in separate windows, lacking the integrated and dynamic view that live attendees enjoy.
Innovation Solution
A system and method that capture images or video streams of both the presenter and the presentation, detecting transitions to superimpose or remove the presenter's image based on gestures or movements, creating a combined image that simulates the in-person experience for remote viewers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the presenter and presentation are displayed in separate windows, then the system is simple to implement and transmit, but the remote participant cannot experience the immersive feel of an in-person presentation
Solution Approach 1:
The patent combines the presenter video feed and presentation content into a single integrated view for remote participants. The system merges these separate elements by detecting when the presenter is not visible in the presentation view, then automatically inserting the presenter's video into the presentation stream, creating a unified immersive experience that replicates the in-person presentation environment.
2Loss of information
If the presenter image is continuously superimposed on the presentation, then the remote participant sees the presenter clearly, but bandwidth usage increases
Solution Approach 1:
The system uses periodic detection of presenter visibility in the presentation view. Instead of continuously transmitting the presenter video, the system periodically checks whether the presenter is visible in the current presentation frame. When the presenter is determined to be invisible, the system then superimposes the presenter image; when visible, the superimposition is removed. This periodic action optimizes bandwidth usage by transmitting presenter video only when necessary.
3Loss of energy
If the presenter image is removed when visible in presentation, then bandwidth is saved, but the remote participant loses the integrated experience
Solution Approach 1:
The system implements a feedback mechanism where the presenter video feed is continuously monitored for visibility in the presentation view. Based on this feedback, the system dynamically adjusts whether to superimpose the presenter image onto the presentation stream. When the presenter becomes visible in the presentation, the system removes the superimposition to save bandwidth; when the presenter becomes invisible, the system adds the superimposition back to maintain the integrated experience.

AI summary
The system and method capture an image of a presenter of a presentation. The image of the presenter may be a still image or a video stream. In one embodiment, the image of the presenter has the background removed. An image of the presentation is captured. The image of the presentation may be a still image or a video stream. A transition, such as a gesture or movement of the presenter is detected. In response to the detection of the transition, an image of the presenter is superimposed on the image of the presentation to create a combined image. Alternatively, in response to the transition, the image of the presenter is removed from the presentation. The combined image or the image of the presentation with the image of the presenter removed is then sent to participants viewing the presentation.
