Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple cameras are used to capture teaching audio and video streams for real-time evaluation, then measurement precision of student learning status is improved, but device complexity and hardware costs increase
Solution Approach 1:
The patent uses digital object manipulation data as a virtual copy/representation of student learning status, replacing the need for multiple physical cameras. Instead of capturing real-world video streams from multiple angles, the system creates and analyzes digital trajectories of manipulated objects, achieving assessment accuracy through data representation rather than physical observation.
Solution Approach 2:
The patent replaces the mechanical camera-based observation system with a computational data processing system. Rather than using cameras to physically capture and analyze student actions, the system substitutes mechanical optical devices with software-based trajectory analysis of digital objects, eliminating hardware complexity while maintaining measurement capability.
2Ease of operation
If traditional two-dimensional video teaching is used, then ease of operation is maintained, but teaching imagery and interactivity are insufficient
Solution Approach 1:
The patent transitions from two-dimensional video teaching to three-dimensional digital object manipulation. By adding the spatial dimension and enabling students to interact with 3D objects, the system enriches teaching imagery and interactivity while maintaining ease of operation through familiar digital interface interactions.
Solution Approach 2:
The system enables students to independently manipulate digital objects and generate their own learning trajectories without requiring complex teacher control or additional hardware setup. This self-service approach maintains ease of operation while significantly improving teaching imagery through active student engagement with 3D objects.
3Device complexity
If one-way video teaching is used, then device complexity is reduced, but interactivity and learning feedback immediacy deteriorate
Solution Approach 1:
The patent implements immediate feedback by automatically analyzing student manipulation trajectories of digital objects and providing real-time learning status information to teachers. This feedback mechanism is built into the core data processing flow, allowing the system to maintain simplicity while dramatically improving learning feedback efficiency through automated trajectory analysis.

AI summary
The present disclosure proposes a method and system of remote operation feedback. The method of remote operation feedback includes: using pieces of training data of a manipulated digital object to perform training to generate a script model, wherein each of the pieces training data includes a training trajectory of the manipulated digital object controlled across degrees of freedom and a corresponding default trajectory type, obtaining pending trajectories of the manipulated digital object controlled across the degrees of freedom from authorized devices by granting the authorized devices to manipulate the manipulated digital object according to an authorization granted command from an authorizing device, inputting the pending trajectories into the script model respectively to obtain concluded trajectory types, outputting at least one animation script to the authorizing device according to the concluded trajectory types and the manipulated digital object when triggered by an authorization revocation command from the authorizing device.
