This document serves as a manual for the UNIPEN visualization and manipulation tool upWorks; a tool which enables you to process on-line handwritten data coming from XY digitizers or pen computers. The software as such is not intended for handling off-line (i.e., optically scanned) handwriting data. You can start the UNIPEN software by typing 'upWorks filename' on the command line. The input file must be in the UNIPEN data format. For example:
upworks data/test.dat
When you have started the application, you will see the main screen. This screen might look like:
The menu structure will always consist of (minimally) the items File and Options. The other - rightmost - menu items that you see are generated by the hierarchy which is defined in the UNIPEN data file. For example, the UNIPEN data file may contain the next statement:
The hierarchy one can define is indefinite and dependent on the
user.
Alternatively, one could create a hierarchy like:
The elements
within the hierarchy are called .SEGMENTs in the UNIPEN file format and jargon
(often pronounced as 'dot-segments').
The menu bar or menu structure always exists in the items File and Options.
The other menu
items you see are generated by the hierarchy which is defined in the UNIPEN data
file (see above).
The Menu page gives an overview of the main
menu structure of the main screen
The main screen depicts all segments at a certain hierarchy level. The hierarchy level is shown in the menu bar. Below follows a description of possible actions by means of:
mouse buttons
Note that there is only one segment viewer, but
it will be visible to the user with a window name which depends on the selected
hierarchy level. In this introduction we only discuss the segment viewer in the
disguise of a word viewer. Using the segment
viewer gives you the possibility of a more detailed evaluation of the UNIPEN
segments.There are two possibilities to pop up a segment viewer. The first is by
selecting a segment in the main screen with the
mouse pointer and push the middle mouse button and
the second is by means of the menu. If you place the mouse pointer on one of the
hierarchical segment items in the menu bar you'll be prompted to make a
selection. You can make a selection by double clicking a list item in the
selection window. The corresponding segment viewer
will then be popped up.
The segment viewer in UNIPEN is divided in
a left part and a right part. When you take a close look, you'll see that the
segment viewer is a pane window. The left part of a segment viewer gives you
information about the contents of the segments and enables you to pop up the
segment manipulator for segmentation and labeling
functions. These functions enable you to edit the data files and change the
hierarchy. The right part of the window contains parameters which give you
information about the left part of the window.
Actions you can perform by means of:
mouse buttons
The Parameters page gives an
overview of all parameters and how to modify their values. Furthermore this page
describes the different signal types.
The segment manipulator page
describes the segment manipulator with which you may
enter new .SEGMENTs or modify and adjust existing .SEGMENTs.
