Solution Overview
Problem
Current teleprompters require manual scrolling by presenters, which can be distracting and inefficient, and lack features like automatic eye-gaze correction and real-time feedback for improving presentation skills.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual scrolling is used in current teleprompters, then the presenter can control the script display, but it causes distraction and reduces presentation effectiveness
Solution Approach 1:
The teleprompter system automatically scrolls the script by detecting the presenter's eye gaze direction and speech content, eliminating the need for manual scrolling control. The system serves itself by using onboard sensors and machine learning models to autonomously adjust the script display based on the presenter's natural behaviors.
Solution Approach 2:
The system continuously monitors the presenter's eye movements and speech through cameras and microphones, processes this data through machine learning models, and provides real-time feedback by adjusting the script scroll position. This closed-loop feedback mechanism ensures the script remains synchronized with the presenter's reading pace without requiring manual intervention.
2Reliability
If automatic scrolling is implemented using machine learning, then presenter distraction is reduced, but system complexity increases
Solution Approach 1:
The machine learning model serves multiple functions: it performs speech-to-text conversion, analyzes the textual representation for content matching, determines eye gaze direction from video frames, and calculates scroll positions. By consolidating these diverse functions into a single multi-functional AI model, the system reduces overall complexity compared to implementing separate specialized systems for each function.
Solution Approach 2:
The machine learning model acts as an intermediary layer that processes raw sensor data (video frames, audio signals) and translates it into meaningful control commands for the teleprompter. This intermediary processing layer simplifies the system architecture by abstracting the complex relationship between multiple sensors and the scroll control mechanism into a unified intelligent decision-making component.
3Measurement precision
If real-time audio analysis is performed, then accurate script position tracking is achieved, but processing time and computational resources increase
Solution Approach 1:
The system performs speech-to-text conversion and textual analysis in advance, before the scrolling decision is made. By pre-processing the audio content and comparing it with the script content ahead of time, the system determines the current script position proactively, allowing the teleprompter to display the appropriate section without real-time processing delays during the actual scrolling operation.
Solution Approach 2:
The machine learning model rapidly processes audio segments and skips through the textual comparison process efficiently by focusing only on relevant portions of the script. Instead of analyzing the entire script sequentially, the system intelligently jumps to and compares only the sections that are likely to be currently displayed or about to be displayed, significantly reducing processing time while maintaining accuracy.
Data Source
AI summary
Techniques performed by a data processing system for a machine learning driven teleprompter include displaying a teleprompter transcript associated with a presentation on a display of a computing device associated with a presenter; receiving audio content of the presentation including speech of the presenter in which the presenter is reading the teleprompter transcript; analyzing the audio content of the presentation using a first machine learning model to obtain a real-time textual translation of the audio content, the first machine learning model being a natural language processing model trained to receive audio content including speech and to translate the audio content into a textual representation of the speech; analyzing the real-time textual representation and the teleprompter transcript with a second machine learning model to obtain transcript position information; and automatically scrolling the teleprompter transcript on the display of the computing device based on the transcript position information.
