Responsive Wearable Technology

Posted on Feb 5, 2014

I first tried a lot of different circuit combinations with alligator clips and different interactions with code. For example, I could have them turn on individually and sequentially (A, B, C) or have them turn on sequentially but stay lit (A, AB, ABC). I tried blinking lights as well, but it didn`t seem appropriate for the scale` concept. I planne

d my circuit out so that there would be no over laps. But just to be absolutely certain, I used electrical tape to hide the circuits. It`s not the prettiest, but it`s the fastest way to prevent short circuiting. I actually had no clue how I would attach the FSR. A needle wouldn`t go through it. So I used fabric glue instead, which worked surprisingly well. Attaching conductive thread to it was a bit of a challenge too since they were so close together. The form factor of the FSR is not the best choice for what I wanted to achieve because it requires that the contents in the bag be concentrated right ON the sensor. It would be ideal if the sensor ran along the entire bottom of the bag so that the measurement of the weight is evenly distributed. Originally, putting the sensor on the shoulder strap was an option, but because the bag I used had a skinny strap, I decided to put the FSR on the bottom of the bag instead. But in hindsight, I think the values would have read much better on the shoulder since the pressure would be more even and stable compared to random objects shuffling inside a bag. Since applying pressure to the bottom of the bag with fingers also worked, a change of concept could be a discrete signal for a friend to leave a party early where the meter would indicate the urgency of leaving
