Intention
Give people a sense of smell dysfunction (anosmia, parosmia) in order to make them empathic to these patients and raise more concerns about olfactory dysfunction.
Project
The project form is an olfactory testing machine placed on a table in the restaurant waiting area. Before customers have dinner, they may be curious and have a try.
The machine releases one odor per question to ask the user to distinguish. While the final odor is a mixed scent to give the user a feeling of parosmia.
See pictures on slides.

Interview
Doctor Lu is using olfactory testing and MRI in his study. I interviewed him to get more understanding of odor and olfactory.
Olfactory dysfunction is related to neurodegenerative diseases. There are many ways to assess this kind of disease in general: Scale, PET/MRI, Structural MRI and olfactory testing. The scale is too subjective. PET/MRI has radiation. Structural MRI is too late to show the disease. In comparison, the olfactory testing is a better choice.
Specifically, the olfactory testing has these advantages: The machine is relatively small and portable. Which makes it suitable for mass screening. Besides, olfactory dysfunction is an early objective indicator of diseases. Because the olfactory cortex is connected to older, subconscious portions of the brain.
Talking about the relationship between olfactory and Covid-19, Dr. Lu was not surprised by the symptom. As he said, the virus might invade the brain and cause frontal lobe damage. Flu also has similar symptoms. However, he agreed that olfactory symptoms are easy to ignore. Since it is not as noticeable as visual or auditory. This is one of the reasons why he included olfaction in his study.

Prototypes
Form Decision
The most challenging part was deciding on the form. For the experience “smell distortion”, the basic form is releasing the odor which is not expected.
But it is so weird to release the wrong odor directly to the user. So I had been trying to think of a more natural form for days.
As the link shows: https://miro.com/app/board/uXjVPGOhG4A=/?moveToWidget=3458764539274013960&cot=14
I came up with 15 forms in the end. Some were fleeting thoughts. Some seemed rational, so I made prototypes to do user testing.
The form No.3, a simple “fruit matrix”. Same fruits a line with different scents. This is the simplest one of these forms. I thought it was clear too. But after the user testing, it was still confusing.
The form No.13, a box with a screen, a camera and odor vent. The idea was “mixing” the use’s expression with an orange scent. I did a user testing of this prototype. It seemed like they were too complex. An iteration was keeping only two expressions.
Then I did another user testing with my friend, who is a UX/UI designer. The testing itself was fair. After that, we had a chat. Because she’s a designer, she was interested in this class. I gave her some project examples. And she gave me an idea: If it was not clear to represent olfactory dysfunction, I could try to make the user feel that smelling is easy. Sounds like a contrasting. But the form was still hard to decide. We continued our chat on some other topics. Then, I got an inspiration suddenly. Why not make it just an olfactory test and put a turning point at the end? This makes it easy for users to go along the process and give the user the feeling of odor dysfunction.
The interesting thing is that it is the original form I took. Except the last question. It’s like a cycle and I return to the start point. However, I learned a lot during the process.

There is an art form called “Olfactory Art”.
