Document Reference Tracking in Video Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During video calls, it is difficult for participants to understand where the speaker is referring to in a shared document, and they may miss content not written in the document being discussed.
Innovation Solution
An information processing device that adds supplement information to the document displayed on both speaker and listener terminals, indicating the speaker's position and emphasizing important content, using analysis of voice data and video calls to synchronize the discussion with the document.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a document is displayed and explained during video call, then communication between participants is enabled, but it becomes difficult to understand which part of the document the speaker is referring to
Solution Approach 1:
The patent applies color changes by highlighting the corresponding document portion in the color indicated by the virtual callout icon. When a participant creates a virtual callout icon with a specific color to mark a document portion, that same color is applied to the highlighted portion in the shared document display, enabling participants to easily identify and understand which part of the document is being referred to during the video call.
2Reliability
If participants concentrate on understanding document content, then comprehension is improved, but they may miss content that is not written in the document being discussed
Solution Approach 1:
The patent implements feedback by displaying not only the highlighted portion of the document but also the text content of the virtual callout icon that contains supplementary information. When a participant creates a virtual callout icon with additional explanations or notes, this feedback information is displayed alongside the highlighted document portion, ensuring that participants receive both the primary document content and the supplementary context needed for complete understanding.
3Ease of operation
If no supplement information is added to the document, then the document display remains simple, but participants cannot easily track the speaker's reference position
Solution Approach 1:
The patent applies segmentation by dividing the document display into distinct visual elements: the original document content, the virtual callout icons created by participants, and the highlighted portions with color-coded indicators. This segmentation allows each element to serve its specific function - the document provides base content, the callout icons provide interactive markers, and the highlighted portions with color codes provide real-time reference tracking - making the system easier to use without overwhelming complexity.

AI summary
Provided are an information processing device, an information processing method, and a program that enable a person to easily grasp which part of a document another person is uttering about when the person and the other person perform conversation while referring to a common document. The information processing device includes a supplement processing unit that adds supplement information to a document displayed on an utterer terminal device used by an utterer and a listener terminal device used by a listener who performs conversation with the utterer in accordance with information regarding the conversation or the document.
