Protophone

A day and half super rapid prototyping of software and hardware

We divided our concur by hardware and software - where I was in charge of software. The hardware will emit an ascii character via serial port triggered by keypads, and the software will receive it and play audio navigation tree according to the input signal. The software was all built in Processing. One of interesting needs for this software was that researchers by themselves needed to be able to update audio files / phone trees based on what they would find out onsite. So, I externalized all navigation tree structure and audio file references as a separate .json file so that they can “program” their navigation tree onsite without having to update the software itself in code.
