Time-Machine Computing

Imagine that your computer has a dial for time-traveling. With such a computer, when you create a document you can simply leave it on the desktop. You can also remove documents at any time. If you later need to refer the previously created information, you can time-travel to the day when that document was on the desktop. You might also see other related information that were simultaneously placed on the computer screen, and these items would help you to recall the activity context at that time. We named such time-centric approach Time-Machine Computing , or TMC.

  2. 2. Problems with current desktop environments <ul><li>Folder Hierarchies </li></ul><ul><ul><li>Naming, classification of files/folders are not trivial. </li></ul></ul><ul><ul><li>Difficult to manage many overlapped windows </li></ul></ul>
  3. 3. Reality is …
  4. 4. Problems with current desktop environments <ul><li>Folder Hierarchies </li></ul><ul><li>Single Desktop Approach ? </li></ul><ul><ul><li>Simple, items are always there and visible. </li></ul></ul><ul><ul><li>Items represent activity status, and act as reminders </li></ul></ul><ul><ul><ul><li>e.g., Digital “PostIt” notes on the desktop </li></ul></ul></ul><ul><ul><li>Spatial layout of information </li></ul></ul><ul><ul><ul><li>(Pile [Mander et al. CHI’92] , Group) </li></ul></ul></ul><ul><ul><li>Does not scale </li></ul></ul>
