Today felt like a lot was accomplished. We finished our DIY garments and wearables and planned activities for the next two days where we will be workshopping at the Siobhan Davies studios with two dancers. We also spent time collecting data from our commercial biosensing products and started our professional documentation process with the lovely Dann Emmons.
The bluetooth module on the breath (stretch) sensor.
This morning, Kate spent time still trying to get the serial data sent via bluetooth from the breath sensor to be read by Processing. It never happened but a USB version does work. When plugged in, Processing takes the serial data from the crotched sensor and then sends this vis OSC to the xOSC and the buzzer garment. A bit more tweaking of the limits of the serial numbers to trigger the buzzers and we will have one DIY garment on one dancer talking to another DIY garment on another dancer.
Here is the wireless buzzer garment and the plugged in stretch sensor.
We spent time this afternoon also collecting data from both the OMsignal shirt and the Polar belt. We created reports of respiratory rate, heart rate and calories burned. This data could possibly be used to create an array for the buzzers, with higher numbers vibrating the left arm and lower numbers vibrating the right (for example). We also plan on using these commercial sensors tomorrow when we work with the dancers and explore research questions in terms of data collection ethics and identity.
One thing that didn’t happen in Day 4 was the connection of Camille’s little muscle wire actuator to a sensor.
So for Day 5, (though she’s wasn’t feeling well), Camille connected a pressure sensor to the neck piece and connected the buzzer to the stroke sensor.
and reconnected the neck band to the 3.7 Lipo battery. The pressure sensor is very simple conductive fabric separated by foam and connect to (+) and (-) reconfigured jumper wires to have a more solid connection for the very sensitive and subtle muscle wire (like a delicate flower) 😉
The rest of the we worked with the OM Signal and Pulsar to get data for Processing with the dancers tomorrow. Camille had a conversation with the makers of OM Signal who said they would try get us the raw data to work with as Kate mentions above, to then find a way to work with it in real time with the dancers.
Pictures of that to come from our documenter Dann Emmons.
