Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of a computer-implemented system that coordinates the use of a presentation analyzer between student and instructor users for analyzing video and audio data associated with presentations, applying standardized scoring algorithms to generate scores for word rate, word clarity, filler words, tone, and eye contact, and calculating a presentation score based on averages or weighted averages.
Innovation Solution
A presentation assessment and valuation system distributed on servers, operably coupled to computing devices, that coordinates the use of a presentation analyzer to analyze video and audio data, applying standardized scoring algorithms to generate scores for word rate, word clarity, filler words, tone, and eye contact, and calculates a presentation score based on averages or weighted averages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a presentation analyzer applies standardized scoring algorithms to analyze video and audio data, then measurement precision of presentation quality is improved, but device complexity increases
Solution Approach 1:
The presentation analyzer divides the complex assessment task into separate analysis modules, each responsible for specific aspects: video data analysis for nonverbal behaviors, audio data analysis for speech characteristics, and automated scoring algorithms for quantitative evaluation. This segmentation allows precise measurement of individual presentation qualities while managing system complexity through modular design.
Solution Approach 2:
The system introduces standardized scoring algorithms as intermediary components that bridge the raw video and audio data with actionable presentation quality metrics. These algorithms act as mediators that transform complex behavioral data into standardized scores (word rate, word clarity, filler words, tone, eye contact), enabling precise measurement without requiring direct complex analysis of all data types simultaneously.
2Adaptability or versatility
If the system coordinates use of presentation analyzer between student and instructor users, then adaptability of the system is improved, but device complexity increases
Solution Approach 1:
The presentation analyzer is designed as a universal system that serves multiple functions for both student and instructor users. Students can use it for self-assessment and practice, while instructors can use it for evaluation of submitted presentations. The same core analyzer handles different user needs through coordinated access, improving adaptability without proportionally increasing complexity.
Solution Approach 2:
The system implements feedback mechanisms that coordinate between users: students receive automated feedback on their presentations, instructors receive detailed analysis reports, and the system tracks usage patterns to improve coordination. This feedback loop enables adaptable user interaction while managing complexity through automated information flow rather than complex user coordination protocols.
3Measurement precision
If standardized scoring algorithms are applied to generate multiple presentation scores, then measurement precision is improved, but loss of information increases
Solution Approach 1:
The scoring system segments the presentation assessment into distinct standardized categories (word rate, word clarity, filler words, tone, eye contact), each with its own scoring algorithm. This segmentation maintains measurement precision for each aspect while managing information loss by organizing detailed analysis results into structured score categories that preserve essential information in a standardized format.
Solution Approach 2:
The system transforms raw video and audio data into standardized score parameters through controlled parameter changes. The scoring algorithms convert complex behavioral measurements into standardized metrics (e.g., converting video frame analysis into eye contact scores, converting audio waveform analysis into word clarity scores). This parameter transformation maintains precision through standardized scaling while managing information loss by focusing on the most relevant assessment dimensions.
