Managing Activities with TV-ACTA: TaskVista and Activity- Centered Task Assistant

We have developed a prototype to-do list called TaskVista that enables a user to create to-do items by typing or by drag-and-drop of files or email messages. TaskVista allows the user to promote items into Activities in our Activity- Centered Task Assistant (ACTA). Activities are pre- structured containers that are created inside the email folder hierarchy to support PIM. Specialized subfolders called Components within each ACTA Activity automatically organize and present information appropriately for aspects of the activity at hand. ACTA is designed to create a more efficient PIM environment with the ultimate goal of providing context metadata for machine learning and automation techniques.
