What does it mean to lack certain senses in the virtual
environment? Thinking of smell, it led me to the inevitable: scratch and sniff
technology.
I discovered a couple of
examples where this technology was used for educational purposes. In
1987, the Baltimore Gas and Electric Company sent scratch and sniff cards to
customers to teach about natural gas leaks. On the back of the brochure
was a drawing of a red flame and the words: ''Scratch
this flame with your fingernail. Sniff it. Let your family sniff it and be sure
everyone recognizes the odor.'' Unfortunately,
the smell penetrated the envelopes without ever being scratched, leading to a
lot of false alarms by customers.
In Northern Ireland, there was a card distributed by police
that smelled like cannabis. It came with other telltale signs of what to
look for with marijuana grow-ops, in order to get the public to help identify
these operations.
London's Odette Toilette is
a "purveyor of olfactory adventures," offering "adventures which range from education and
communication workshops for groups in the fragrance industry, through to
corporate entertainment for people who want to offer their team or clients
something unusual."
Then, there was the 1960 Scent of Mystery which tried to incorporate aromas into theatres with "Smell-O-Vision." It released 30 different scents in the air in conjunction with the movie. Needless to say, it didn't make it as a part of our ongoing movie experience.
These experiments with smell do bring up interesting questions around the issue of senses and how they connect to learning in the virtual environment. Are there ways online educators can capture and capitalize on students' senses in order to create increased engagement and learning?
