For this assignment I decided to use capacitive touch sensors to respond to different kinds of physical interactions. I envision the project to allow the user experience physical interactions like a game with different kinds of physical interactions getting different levels of responses. The response will be in the form of a sound or specific tune. For instance, the sound played when the user hugs someone compared to the one after a handshake contains more excitement. I think this project would be a small easy way to spread happiness.
To prototype this project, I created a capacitive touch sensor using aluminum foil. I also use the CapacitiveSensor library available on the Arduino website to make this sensor. I play a certain frequency when the sensor is not engaged and a different one when it is. This proof of concept can be extended to have more number of sensors and different tunes to create the project imagined.
It will be interesting to find ways to incorporate this into the clothing of the user. I also think I will enjoy coming up with the different tunes that play in response to different stimuli.
