Abstract

A method of retrieving the current task after dealing with a pop-up notification within the same application is proposed. When a notification is pushed, a detective module detects whether the current task is interrupted or not. If the current task is interrupted, its interface along with the shortest route is stored as a snapshot. The shortest route to the current task works as a shortcut, which can be computed by analyzing the user behavior. The user can quickly and easily go back to the interrupted task by calling the snapshot.

A method for task retrieval after interruption within an application on touch devices

Mobile phone or other touch devices are commonly used and almost become necessities of our daily life.There are many pop-up notifications pushed by various applications, such as an update notification. The problem is how to retrieve a previous task after dealing with a pop-up notification in the same application.

Take an example as an illustration. Suppose that the user is reading an article when a notification of the same application pops up.If the user quits the current task and deals with the incoming notification, the user might need to cross many levels to go back to the article that the user previously read. To some extent, it is time-consuming and not user-friendly. The existing methods allow the retrieval of the task that belongs to another application. That is, the task retrieval can happen only between applications rather than withinone application. Users cannot quickly go back to their previous task after dealing with the notification by using the existing methods. This disclosure provides a method to easily return to the previous articleafter dealing with the pop-up notification within one application.

In this disclosure, a method of retrieving previous tasks by using a snapshot collection is proposed.

When a notification is pushed, a detective module determines whether the current task is interrupted or not. If the current task is interrupted, its interface is stored as a snapshot, which can be called later. During this process, the user behaviors are analyzed,and the shortest route (shortcut) to the current task is computed and stored along with the task interface. When the user calls the stored snapshot, the task interface where the user quits the task is displayedby using the shortest route.

All the stored snapshots are organized in a tree mapping format. See figure 6 for how the snapshot collection is organized. Once the user returns to the previous task, no matter by using this mechanism or by launching the task again in an ordinary way, the stored snapshot will be deleted. Users can assign a certain size of memory to store these snapshots. When the storage area is full, the earliest snapshot is removed to save space for new snapshots. All snapshots are stored chronologically.

By using this method, users can quickly go back tothe previous task after dealing with the pop-up notification from the same application. This disclosure has the following advantages:


·

·

·

It is a stand-alone mechanism that can be used on any touch devices and is independent of applications.

This method makes retrieving the previous task after dealing with the notification within one application more easily and quickly.

The snapshot collection is created automatically and it is shown as a small icon at the top of the screen, which will not affect user experience.
