I have presented my thesis idea few times. There were some questions that I got from my audience. Here are my answers to make them clear.
I will be measuring changes in body during the day, and I will be correlating this with emotional changes. I can not estimate exact emotion, but I can say, calm, normal, anxious/stresses/anger/happy(these four are almost the same data, because Galvanic Skin Response shows change in your bodies resistance according to amount of sweating)
I realized, there are sometimes that I cannot control changes in my emotions and loose my temper. After realizing this, I start controlling myself. Whenever I realize there is a change in my emotion, I try to calm down and thing about it again. This helps me to realize if I am doing something wrong or right. So, as a start I see this thing as a screen for myself to realize my feelings and control them. As a start, I am doing this project for myself.
Later on I have different ideas to implement by using the same idea. For example, knowing what effects me in New York, or a driver feelings screen or a genre visualizer.
I will be using galvanic skin response to see reactions of your body. You can figure out emotional changes by looking at to resistance between two points on the body. This is effected by the level of sweating.
Also, I want to use heart rate monitor, because seeing changes in the heart rate might be useful or, it might help me to figure out if the changes in galvanic skin response is because of a physical activity.
I will not be using EEG, because EEG interferes with galvanic skin response and even a little movement can effect EEG data. I am designing this product for people to wear in their daily life. So, they will be moving.
I will be using some sort of abstract shapes. Using hight or graphical elements doesn’t seem so well. I am sensing if there is any change in the emotions, not exactly what you are feeling, and also cumulative data. So, using color code seems easy and meaningful for now. Or another option can be using abstract shapes like, if shape has sharp edges that means danger etc.
If you don’t want to make this data public (let’s say you are in a grocery store), you can turn it off or unattached the screen. Another option might be having a headphone system, so, you can hear it but people cannot. So, you will be still aware of it and have a chance to change it.
Other possible scenarios
Maybe, some sort of screen for traffic. This can be for personal awareness or for public awareness.
Mapping emotional changes during a movie and instead of calling a genre for the movie calling something related to graphics or colors.
