The Integrated Interactive Visualizer Video Instructional System

in development by
M. Chan M.I.E.E.,
J. Ho,
E. F. James M.A. D. de IIIeC
and M. Sherk Ph.D.

This multimedia system allows for:

i) management of text

- explanations on screen of teaching points,
- integrated exercises with automatically presented right and
wrong answer messages
- record keeping of student performance
- short video dialogues to give "live" examples of grammatical
structures explained in the on-screen textual presentation.

ii) computer generated sound (digital sound) for presenting
grammatical structures to be repeated orally as well as
pronunciation drills to be completed

iii) visualized intonation contours - those very important
features which make or break effective linguistic
communication. Presentation of intonation (speech melody)
contours accompanying basic sentence types. These structures
are presented "aurally" as well as "visually" on the monitor
in the form of snake-like lines . These visualisations are
supplemented by the display of the sentence being drilled
(at the top of the monitor screen) as well as the graphic
display of individual syllables along the intonation
contour. The visualised intonation contour of the model
sentence appears -- in real time -- on the top half of the
screen and the instantaneous visualisation of the student's
imitation (as he/she is saying it) appears on the lower half
of the screen. This permits an instant visual comparison and
subsequent correction since as soon as the student repeats
an imitation, his/her first imitation is automatically
erased and the new one is again instantaneously traced on
the screen to permit further comparison and correction.
It can be seen then that the computer terminal becomes an
individual multi-media learning laboratory.

An article, describing the system much more, fully is to appear
in IRAL in 1993. For preprints please contact: Prof. E.F. James,
