Instead of using an app, what if you could send a signal to eye-contact someone you are interested in talking to, in a social setting, even from afar? I’m not proposing a different way to start a date. I’m exploring a new usage of Bluetooth in the field of human interactions. When I found out that Intel Curie modules can be assigned to act as central and peripheral BLE devices, I immediately wanted to make these glasses. (Learn more about CurieBLE from here.) Thanks to a tutorial on Adafruit, the reference framework of a 3D printed LCD glass is readily available. What I added onto the Adafruit tutorial are the BLE control (instead of a switch control) of two pieces of glasses at the same time, with one being the master and the other being the slave, and redesigned 3D printed frames.”
