Scaffolding: Progress Review - Team 8

The custom controller we settled on for the project was our treasure map design, which we made to expand upon the concept of the video game "Hidden Folks." Since the purpose of the is to explore the maps and find certain objects/people, we decided to use the classic "X" marks the spot treasure map. Since the game itself has quite a simple interface and controls, our team decided to create a visually immersive controller, using a similar art style to that of the game while also adding our own spin to it.

The control features two cylinders on each side, simultaneously representing a rolled-up scroll and providing sturdy handles for each hand. There is an "X" button in the center map portion of it, using a light sensor that maps to either "on" or "off" to select something within the game. There are two buttons for the "up" and "down" controls, and a touchpad that serves as the "left" and "right" controls as well.
