Task Interruption Recovery System Using Visual Activity Replay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern workers face difficulties in remembering the stage of a task or activity after interruptions, leading to decreased productivity due to the need for manual task management and time-consuming reorientation upon returning to tasks.
Innovation Solution
A system that records user activities, detects interruptions, and presents a visual representation of pre-interruption activities, including screenshots or a replay of significant events, to assist in task recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual task management is used, then the system complexity is low, but the productivity decreases due to time-consuming reorientation after interruptions
Solution Approach 1:
The system records user activities in advance before interruptions occur. When an interruption is detected, the pre-recorded activity data is immediately available for presentation, eliminating the need for real-time data collection and reducing reorientation time after interruptions
Solution Approach 2:
The system creates visual copies (screenshots) of the user's desktop state at specific moments. These copied visual representations are stored and later presented to help users quickly recover their task context without manually recalling or searching for task information
2Loss of time
If activity recording and visual presentation systems are implemented, then the productivity improves by reducing reorientation time, but the device complexity increases
Solution Approach 1:
The system extracts only the most relevant visual information (key screenshots representing significant task states) from the continuous activity stream. By selecting and presenting only essential visual cues rather than complete activity logs, the system reduces reorientation time while minimizing the complexity of data management and presentation

AI summary
One embodiment of the present invention provides a system for assisting a user in recovering from a task interruption. During operation, the system records the user's activity while the user is performing a task, and detects an interruption to the task. Upon the detection of the interruption, the system transfers to a storage the recorded user activities during a predetermined time period before the interruption. The system presents a visual representation of the recorded activities to the user, thereby assisting the user in recovering from the task interruption.
