Assignment2: Expressive Wearable

Concept: “Warm company” is a scarf that can shine at night. It usually looks like the same as ordinary scarves, but once people wrap their mouths with it, it will emit yellow light when they feel the heat exhaled by people.

Objective: My wearable is inspired by the feeling of “loneliness”. When I walk alone on a snowy night in Toronto and see couples or a group of friends walking together on the street, sometimes I feel very lonely. I think there are many people like me who choose to walk home quietly after work or after a party. Although I don’t always have the idea of “I’m lonely by myself”, once I do, I often feel depressed all night. So my wearable is to bring a little comfort to everyone who has to walk alone at this time. Whenever they look down, they can see their scarves glowing yellow. Hope that on every cold night, even if there is no one beside them, these warm lights can always accompany them.



I got an electric shock the first time I tried. I was scared.%e8%a1%a8%e6%83%85%e5%8c%851



On the second try, the circuit was improved and safe.%e8%a1%a8%e6%83%852

Reflections & Next Steps:

This assignment is like a demo of my designed wearable. It seems that my design is feasible. I only connected five light bulbs on one side of the scarf in this assignment, but I may connect more light bulbs in the future which are enough to circle around the bottom of the scarf. In addition, a heat sensor needs to be installed on the top of the scarf, that is, the side close to the neck, to meet my original design idea of turning on the light bulb by sensing the heat emitted by people’s breathing.

Assignment1: Speculative Wearable

Concept: My wearable is a black mini earring that can detect how long you’re watching the screen with the blue laser emitted by the screen. Once it’s over 3 hours, the device will make a slight sound to remind you that you should give your eyes and body a break. You just need to press the glass gently to stop the sound.

Objective: My wearable is meant to remind people balancing their work time and rest time reasonably. Even if our work and study situation forces us to use computers for long periods  every day, we should stay away from electronic devices for a while. This is to protect our physical health, especially the eyes’ health. In addition, sometimes we feel tired but embarrassed to say it to others. The sound of the earring will make others realize that you have been working for a long time, you need a rest.
