Inspiration
Google Glass is one of the android device. By saying "OK glass", you can wake up your glass in anytime and any position without using your hand. So why not make a voice calculator app for Google Glass that can calculate numbers for you instantly.
This app is using Google's built-in voice recognition engine to record user input. I simply used data extraction to convert user's "string" input into numbers and operators. The app will process the calculation and out put the result. User can wake up the voice calculator by saying "Ok Google, Calculate ......"
This is my first time programming an android app. I start from "Hello World" program into voice command and voice input. It teaches me a lot about programming for a wearable device. I'm going to refine this voice calculator and learn more about programming mobile devices. The future voice calculator will be more powerful and can even graph user's input function as a graphic calculator.
