Device development requires knowledge and expertise in various fields including Computer Science (programming etc) and Electrical Engineering. To develop a device from scratch, I recommend you start off with a bunch of buttons and a micro controller. Learn how to program microcontrollers and if you find it too difficult, start off with other programming languages on the computer.
