Wearable tech is getting to be a big thing. But how we interface with this gear is still a bit of a work in progress. To explore this space, Bruce Land’s microcontroller course students came up with an acoustic interface to assist with navigation while walking. With style, of course.
Bruce, from the Cornell University School of Electrical and Computer Engineering, has been burning up the Hackaday tips line with his students’ final projects. Here’s the overview page for the Sound Navigation Hat. It uses a PIC32 with GPS and compass. A lot of time was spent figuring out how to properly retrieve and parse the GPS data, but for us the interesting bits on that page are how the directional sound was put together.
