Runners aid (Posture Sensor) workshop #3

The world of sensors and feedback

For this assignment. We were given a choice of making sensors or to try out existing sensors like heart rate monitor, EMG sensors to select and experiment with keeping in mind the idea of self reflection or self expression.

I tried out the the EMG sensor with my class Nick. From my understanding of the sensor  senses muscle activation. You can then use it to connect to the arduino to get value mapped to sensor value by using a simple serialInputOutput code from sketch examples.

Testing out the the emg sensor. The EMG sensors uses a surface which acts like a bandage on the skin. The accuracy of the reading go down for more than a couple uses.

1)How could your design follow the design recommendations? 1) Instead of representing numbers, represent through materials and aesthetic visuals

 

Thee posture sensor is used for “running in the dark”it not only activates light. This helps the runner maintain a steady speed while keeping them safe. This falls under the idea of biofeedback, using the bodies momentum.

2)Instead of designing for affect-as-information, design for affect-as-interaction. Treat the biofeedback as a prompt for social interaction or personal self-reflection.

I see this sensor as being more of an interaction with the surrounding. Night runs are a great time for reflection and solitary activity. Sometimes, due to some areas not having enough light runners are put in harm’s way from vehicles and unlit paths. I can also see the device having two lights. One to illuminate the path, and one which maybe is connected to a heart sensor.

3) Have enough ambiguity that the individual must interpret what the visualization means for themselves.

4) When designing, constantly reflect on how you are making meaning for the individual through your designs. Could you be insinuating that something is negative, unhealthy, etc. ?

5) Reflect on the authority you are giving to the biofeedback device. How could you transfer this authority to the individual instead?

6) Instead of focusing on self improvement

Testing 

Testing out to see the sensor worked. For this I powered the two conductive materials and grounded the metal piece to achieve the led to go off and on. This is a way to switch the circuit on and off.

Using the same principle of circuit connections, I then proceeded to light two LEDS.
