explores the problems and possibilities of computer-controlled scent
output. I begin with a thorough literature review of how we smell
and how scents are categorized. I look at applications of aroma
through the ages, with particular emphasis on the role of scent
in information display in a variety of media. I then present and
discuss several projects I have built to explore the use of computer-controlled
olfactory display, and some pilot studies of issues related to such
display. </font></p>

quantify human physical limitations on olfactory input, and conclude
that olfactory display must rely on differences between smell, and
not differences in intensity of the same smell. I propose a theoretical
framework for scent in human-computer interactions, and develop concepts
of olfactory icons and �smicons�. I further conclude that scent is
better suited for display of slowly changing, continuous information
than discrete events. I conclude with my predictions for the prospects
for symbolic, computer-controlled, olfactory display. </font></td></tr>
