Presentation Controller Page Tracking Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Attendees in presentations often lose track of the current page being presented due to inability to view the presenter's screen, leading to disconnection from the document being shown.
Innovation Solution
A presentation controller detects the activation of a document page on a presentation device, tracks the consecutive active time, and provides an output indicating the page number when the threshold is exceeded, allowing for real-time page number updates to a target source, such as through audio or instant messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If attendees use their own screens or printed materials to follow along, then they can view the document content, but they lose track of which page is currently being presented
Solution Approach 1:
The system implements feedback by automatically detecting which document page is currently active on the presentation device and transmitting this information back to attendees' devices. The presentation controller monitors the active page and sends real-time notifications to target sources (attendees' screens, mobile devices, or printed materials), ensuring they receive feedback about which page is being presented without needing to visually observe the presenter's screen.
Solution Approach 2:
The patent introduces a presentation controller as an intermediary component between the presentation device and attendees' devices. This intermediary automatically detects the active page, determines when to send notifications (based on threshold criteria), and transmits page number information to target sources. This mediator eliminates the need for direct visual contact between attendees and the presenter's screen while maintaining accurate page tracking.
2Measurement precision
If the system provides real-time page number notifications to all attendees, then page tracking accuracy improves, but system complexity increases
Solution Approach 1:
The presentation controller performs self-service by automatically detecting which page is active on the presentation device without requiring manual input from the presenter or attendees. The system autonomously monitors the document state, evaluates threshold criteria, and generates notifications independently, reducing the operational burden on users while maintaining high tracking accuracy.
Solution Approach 2:
The system utilizes parameter changes in the document state (page transitions, activation events) as triggers for notification. By monitoring changes in document parameters (such as active page identification, time thresholds), the system automatically initiates page number transmissions when specified conditions are met, improving accuracy while keeping the control logic relatively simple through event-driven architecture.
Data Source
AI summary
Methods, apparatuses, and computer program products for indicating a page number of an active document page within a document are provided. Embodiments include detecting, by a presentation controller, activation of a document page on a presentation device; in response to detecting the activation of the document page on the presentation device, tracking, by the presentation controller, an amount of time that the document page is consecutively active on the presentation device; determining, by the presentation controller, that the amount of time that the document page is consecutively active on the presentation device exceeds a predetermined threshold; and in response to determining that the predetermined threshold has been exceeded, providing to a target source, by the presentation controller, an output indicating a page number of the document page while the document page is active on the presentation device.
