The thoughtfulness of this project is appealing as an object identification device. Though it is difficult to consider a realistic application for this, it is intriguing to imagine a world physically marked with identification that you can hear, feel, and see. The requirement of a haptic interaction with an object in order to get feedback from the audio effect is the true function that entices me.
Interact with one thing, produce a resulting sound from it, then that sound is heard. The indirect relationship between the “input” object and the direct input to the program is where I find inspiration.
