Motion Sensor Authentication for Audio-Visual Terminal Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote education systems cannot accurately authenticate whether a learner has viewed an audio-visual program, as they rely on examination questions that may be answered correctly without viewing, and the confirmation process is time-consuming and prone to errors, especially when the learner is distracted during code input.
Innovation Solution
An audio-visual terminal equipped with a reproducing part, motion instructing part, motion sensor, sending part, and coding part that instructs the viewer to make specific motions and detects these motions to authenticate genuine viewing, transmitting this information to a viewing authentication system for verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a viewing confirmation code consisting of a predetermined character string is transmitted via the audio-visual terminal, then the viewing authentication is achieved, but the viewer may miss important video images or descriptions because the viewer must look away from the audio-visual program to input the code
Solution Approach 1:
The patent replaces the mechanical manual input method (typing codes on keyboard) with automatic motion detection using sensors. The motion sensor detects the viewer's body movements and automatically transmits the motion data as viewing confirmation, eliminating the need for manual code input and thus preventing distraction from the program content.
Solution Approach 2:
The system uses the viewer's own body movements as the authentication mechanism. The motion sensor captures the viewer's natural motions during program viewing, and the system automatically processes these motions as authentication data without requiring the viewer to perform separate authentication actions that would divert attention from the program.
2Reliability
If the viewer manually inputs a viewing confirmation code, then the authentication process is completed, but the confirmation process takes much time
Solution Approach 1:
The system continuously captures motion data from the viewer during program viewing as preliminary action. The motion sensor operates throughout the program, collecting motion information that can be immediately processed as authentication data, eliminating the need for separate manual code entry steps and reducing overall authentication time.
Solution Approach 2:
The patent replaces time-consuming manual code input with automatic motion detection and processing. The motion sensor continuously monitors viewer movements and the system automatically processes this data into authentication results, significantly reducing the time required for confirmation compared to manual typing and submission processes.
3Measurement precision
If examination questions are used to check learner understanding, then the learning outcome is assessed, but it is impossible to know whether the learner has actually viewed the program
Solution Approach 1:
The patent replaces indirect assessment methods (exam questions) with direct observation through motion sensors. The motion sensor directly detects the viewer's physical movements and programs the terminal to capture motion data that proves actual program viewing, providing reliable verification of viewing behavior rather than relying on potentially fabricated exam answers.
Solution Approach 2:
The motion sensor acts as an intermediary between the viewer and the authentication system. It captures objective motion data that serves as proof of viewing, bridging the gap between the viewer's actions and the system's verification capability. This intermediary provides reliable evidence of actual viewing that cannot be faked like exam answers.
