Electronic Device Guidance Video Control for Step Completion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guidance videos for electronic devices, such as printers, are repetitive and lack flexibility, leading to user confusion and inefficiency, especially when users pause and restart them, as they cannot easily distinguish completed steps from remaining steps.
Innovation Solution
The electronic device allows users to pause and restart guidance videos, adjusting the reproduction speed based on the user's progress and completion of tasks, using internal sensors to determine the user's job status and adjusting the video playback accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guidance video is repeatedly displayed to ensure user understanding, then the completeness of information delivery is improved, but the user confusion and inefficiency increase due to inability to distinguish completed steps from remaining steps
Solution Approach 1:
The guidance video is divided into multiple steps, and the system tracks which steps have been completed by the user. When the video is restarted, only the remaining steps are displayed, eliminating redundancy and confusion about completed versus remaining steps.
Solution Approach 2:
The system uses sensors to detect user actions (such as cover opening/closing) and updates the guidance video playback accordingly. This feedback mechanism allows the system to remember what the user has already done and adjust the video playback to show only what remains, preventing confusion.
2Productivity
If the guidance video is displayed at normal speed continuously, then the information is delivered efficiently, but the user cannot pause to perform tasks and restart at convenient timing
Solution Approach 1:
The guidance video playback is made dynamic, allowing users to pause and restart at any time. The system adapts the playback by detecting user actions and adjusting the video restart point, combining the benefits of efficient information delivery with user flexibility.
Solution Approach 2:
The system automatically detects user actions through sensors and determines when to restart the guidance video, eliminating the need for manual intervention while providing convenient timing for users to perform tasks.
3Reliability
If the guidance video is restarted from the beginning, then all steps are reviewed, but the user cannot easily distinguish which steps have been completed and which remain
Solution Approach 1:
The guidance video is segmented into discrete steps with clear completion criteria. The system tracks progress through these segments and only displays remaining steps upon restart, maintaining clear distinction between completed and remaining steps while reviewing necessary information.
Solution Approach 2:
The system extracts and removes completed steps from the guidance video playback upon restart, presenting only the remaining steps to the user. This extraction eliminates confusion about which steps have been completed while ensuring all necessary information is still reviewed.

AI summary
An electronic device includes: a display unit configured to display a guidance video indicating contents of a job; a reception unit configured to receive from a user an instruction to pause the guidance video reproduced on the display unit and an instruction to restart the paused guidance video; and a control unit configured to execute control to change a reproduction speed of the restarted guidance video in a case where the instruction to restart the paused guidance video is received.
