basic arduino sound sensor system.
prototype: frustration makes use of sound sensors to pick up sound, convert it into movement, while also sending signals into the arduino to be used in a p5.js sketch. to start, i first set up a basic sound-sensor system.
tests on different forms
i came up with two different approaches for the prototype: hopelessness. the wired one was to be worn, and would be able to pick up the most subconscious expressions. the windmill required the user to be more proactive and required a bit of sound monitoring. there are issues with both- the wired one would pick up unwanted noises as well, and the windmill might not be the most accurate in the collecting of data, and strayed a little further away from the original concept of monitoring subconscious actions.
after some feedback and thinking, i will proceed on with the wearable prototype. it is a bit closer to what i wanted of collecting subconscious actions.
base structure of the prototype.
when the sound sensor was attached on the wired prototype, it wouldn't hold up such that the sound sensor is posititioned at the mouth any more. i had to create and structure that would make use of other body parts to keep the sound sensor at where it should be.
base structure with different forms and materials.
got my brother to help me test this out. the structure holds, but is very hard to put on. i realised this might be an issue with future iterations. the sound sensor might be in the right position, but the individual might not be able to put it on comfortably. this iteration is more comfortable to wear though, in comparison to the 1st and 2nd which relied on the prototype being hooked on the ears. this was also able to pick up sound better.
sketching out a proper structure.
i had a bit of trouble trying to envision out what the prototype should resemble. using both blue modelling foam and sketches, the structure of the prototype was slowly developed.
in order to solve the issue of the prototype being difficult to put on, i came up with the idea of making the mouthpiece area detachable. the area where it detaches could be connected with a bendable wire so it is adjustable as well.
blue foam model to be 3d printed.
i had a bit of trouble trying to envision out what the prototype should resemble. using both blue modelling foam and sketches, the structure of the prototype was slowly developed. the next step was to finalise the dimensions and send it out for printing.
after a pathetic attempt at 3d modeeling, i got my friend jordan to help with the modelling and 3d printing.
thankfully, this was quite straightforward to understand, and he gave me a lot of advice on the structural strength as well. he also helped me film a timelapse :')
magnet was too weak to hold its structure.
making the detachable component stronger.
i had failed to consider the characteristics of the material in the last iteration. the magnet and wire are delicate parts, and to build on that, i had to use design the plastic component such that it was stronger and could hold its structure. the detachable component was now longer, and had a little latching system so that it would hold the sound sensor in place.
final prototype-hoplessness! 3d print credit: my friend jordan! model: medha!
