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.

Method for quickly recovering from task interruption

One embodiment of the present invention provides a system for estimating a number of stress factors related to a worker. During operation, the system records a sequence of work steps of the worker for a predetermined period of time, and extracts a number of temporal patterns (T-patterns) from the sequence of work steps. Based on the extracted T-patterns, the system calculates T-pattern statistics, and applies a classification method on the calculated T-pattern statistics to produce a classification result. The system then estimates one or more of the stress factors based on the classification result.
