The majority of the time during the third week of the SMARTER RET program was spent reading current research articles on augmented reality. Specifically, we focused on reading research regarding mobile implementation of AR as well as AR implemented within a learning environment. We were able to observe a swarm robot project which uses AR built into a mobile phone app to identify the location and orientation of robots. In addition to spending time reading articles, we also began to work through several basic Arduino projects to become familiar with the programming language, as our schools have several Arduino kits already. Phil had the idea to create a sensor that could interface with the Arduino, and this resulted in background work on conductivity sensors. He was able to write code that displayed the voltage passing through a diy conductivity sensor, and created the prototype circuitry on a breadboard connected to the Arduino Uno provided by NYU Poly. Julian spent time working with Android Studio, which culminated in the creation of an app that allows the user to remotely control a dc servomotor.
