I came up with the current concept and made the first prototype, which involves two force sensing resistors: one is for switching on and off of the system, and the other one is for flip back and forth between the inaudible version and audible version of the audio assets. Later on, I decided to simplify the system by deleting the switch function. This way the accessibility of the device is increased, and the idea of the "ever presence of audio memories in the environment" is enhanced.
Is this a good/useful/informative piece of content to include in the project? Have your say!
