When a user is engaged in sensemaking using a media, the user's work
involves navigating to previously visited view places in the workspace.
To achieve this, a workspace is navigated by obtaining a history list
that may include a degree of interest and/or location information related
to previous view places, and navigating the workspace based on the
history list. The workspace may be further navigated by retrieving the
location information related to one of the previous view places from the
history list, and displaying the previous places based on the location
information. The history list may be constructed by detecting an activity
in a current view place, determining a degree of interest of the current
view place based on the activity, and storing the degree of interest and
the location information.
