Web Conference Annotation Visibility Decay Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In web conferencing, existing systems lack effective methods to manage the visibility and relevance of annotations based on participants' expertise levels, leading to inconsistent and potentially confusing presentations.
Innovation Solution
A method that assigns relevance parameters to annotations and generates decay models to control their visibility duration based on participants' expertise levels, ensuring that annotations are presented accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If annotations are made visible to all participants for the entire presentation duration, then all participants can access the information, but the presentation becomes cluttered and less clear for participants with different expertise levels
Solution Approach 1:
The system applies local quality by differentiating annotation visibility based on participant expertise levels. Each participant receives a customized view where annotations are filtered and timed according to their specific knowledge level, rather than applying a uniform visibility rule to all participants. This resolves the contradiction by making the presentation clear for each individual while maintaining information accessibility for all.
Solution Approach 2:
The system implements dynamics by making annotation visibility time-dependent and participant-specific. Annotations are displayed for different durations based on decay models that consider both the annotation's relevance and the participant's expertise level. This dynamic approach allows the presentation to adapt its information density over time for each participant, resolving the static contradiction between universal accessibility and individual clarity.
2Loss of time
If annotations are displayed for long durations, then participants have time to process the information, but less relevant annotations remain visible and cause confusion
Solution Approach 1:
The system applies periodic action through decay models that systematically reduce annotation visibility over time. Instead of static long-duration display, annotations are dynamically dimmed or removed based on elapsed time and relevance decay. This periodic fading allows participants adequate processing time initially while automatically removing less relevant annotations later, preventing information clutter.
Solution Approach 2:
The system changes parameters by adjusting annotation visibility based on multiple dynamic factors including elapsed time, annotation relevance scores, and participant expertise levels. The decay model continuously modifies the visibility parameter, transitioning annotations from fully visible to partially visible to completely hidden based on changing conditions, thus balancing processing time needs with relevance maintenance.
3Adaptability or versatility
If the system tailors annotation visibility to individual expertise levels, then presentation relevance is improved, but system complexity increases
Solution Approach 1:
The system applies preliminary action by pre-calculating decay models for each annotation based on its relevance to presentation portions and the participant's expertise level before the presentation begins. This upfront computation of personalized visibility parameters avoids the need for complex real-time decision-making during the presentation, reducing operational system complexity while maintaining high adaptability.
Solution Approach 2:
The system uses copying by creating simplified decay model representations for each participant based on their expertise level. Rather than implementing a single complex adaptive system, the system generates multiple simplified copies of the annotation visibility logic tailored to different expertise levels, making the overall system more manageable while achieving personalized adaptation.

AI summary
A plurality of annotations can be received for a presentation presented in a web conference. A respective relevance parameter can be assigned to each of the annotations. Each relevance parameter can indicate a relevance of a respective annotation to a portion of the presentation to which the annotation pertains. For each of the annotations, a decay model based on the respective relevance parameter can be generated. The decay model can indicate different durations of time the annotation is to be visible to different participants participating in the web conference based on respective expertise levels of the participants. Each respective annotation can be presented with the presentation in accordance with the decay model generated for the respective annotation.
