Where is my data ?
3
Data Mountain is a novel user interface for
document management designed specifically to take
advantage of human spatial memory
4
As the page being dragged, other page move out of
the way so the page being moved is not occluded
5
Data mountain is 3 D document management systems

• Allows users to place the document at arbitrary
  location
• Allows users to informally arrange their space in
  a very personal way
• 3 D perception is used to allow for
  representation of the large number of the web
  page thumbnails with minimal cognitive load
• User can place web page (or document) anywhere on
  the mountain
• when a page is being moved, other pages are moved
  out of the way
• Page title are displayed whenever the mouse moves
  over the page
• Because of using spatial memory, make it easier
  to find document in the information workspace.

User Study

• Hypothesis the effectiveness and usability of
  the Data Mountain depends in part of the transfer
  of real world spatial memory to a virtual
  environment.
• Method
• Subject 32 experienced IE4 users participated
• Equipment The study run on high end Pentium
  machines, 100 web pages were used
• Procedure participated device in 3 groups
• 1. Users stored and retrieved web page using the
  standard IE4
• 2. Users using Data Mountain (DM1)
• 3. Users using Data Mountain 2 (DM2), which
  incorporated design changes suggested from DM1

10
Examples of the four cueing conditions used in
the study
11
Four main dependent variables were used in this
study

• Web page retrieval time
• The number of incorrect page selected prior to
  finding the correct page
• Number of trail for which the participant failed
  to retrieve the correct page within the
  two-minute deadline
• The participants s subjective ratings of the
  software

Future work

• Solve the problems
• Two pages can end up in the same location
• More attributes
• Additional area explore further
• The relative contributions of this successful
  study of the various components ( 3D, audio,
  title display, page avoidance )
• and etc.
