Automatic Process Guidance for User Interaction Sequencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In computer systems, particularly in industrial and automotive applications, it is challenging to ensure that new or inexperienced users interact correctly with the system, as they may not follow the required sequence of interactions to operate machinery safely and efficiently.
Innovation Solution
A system that senses user interactions and records tasks, allowing for playback and test generation, enabling automatic control of the system based on recorded interactions, and providing a tutorial mode for learning the correct sequence of operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user interacts with a complex computer system without guidance, then the system can be operated, but the user may not follow the correct sequence of interactions leading to errors or unsafe operations
Solution Approach 1:
The system records a correct sequence of user interactions (task recording) before the user needs to operate the system. This pre-recorded guidance is then played back to the user, providing step-by-step instructions on the correct interaction sequence, ensuring reliable operation without requiring the user to memorize complex procedures
Solution Approach 2:
The system provides feedback to the user by comparing their actual interactions with the recorded correct sequence. When deviations are detected, the system can alert the user or guide them back to the correct path, ensuring that interactions follow the required sequence for safe and correct system operation
2Reliability
If the system provides detailed guidance for correct interactions, then user correctness is improved, but the system complexity increases
Solution Approach 1:
Instead of creating a complex guidance system from scratch, the system copies the correct user interaction sequence by recording it during a demonstration or first-time setup. This recorded interaction sequence serves as the guidance template, simplifying the system architecture while ensuring correct user behavior
Solution Approach 2:
The system automatically generates its own guidance materials by recording actual user interactions during initial setup or demonstration. This self-service approach eliminates the need for manual creation of complex guidance systems, reducing development complexity while maintaining high reliability
3Ease of operation
If the system records and plays back user interactions, then learning is enhanced, but the time required for training increases
Solution Approach 1:
The correct interaction sequence is recorded and stored before the user needs to learn the system. This pre-prepared guidance can be quickly played back during training, reducing the time required compared to real-time instruction while maintaining ease of learning through visual and auditory guidance
Solution Approach 2:
The system allows users to review the recorded interactions at their own pace, with the ability to pause, rewind, and replay specific sections. This periodic review mechanism enhances learning efficiency by allowing users to focus on difficult areas without time pressure
