Reviving SkiFree Game with BordFree

Overview

The BordFree is a revived version of the Microsoft hit SkiFree with an innovative tilt-control system.

Explanation

During the game, the user is placed in the boots of a snowboarder that steers its way in a ski slope. A color TV scrolling from bottom to top provides the capability for BordFree players to see their character while the user sees the obstacles which will slow down the speed of the user when hit. Based on the total distance traveled, the purpose of the game is to obtain high score before the Pacman eats the character. The number of on-screen obstacles was limited to 10 The movement ability of the character will range from diagonal in each direction to fully forward motion.

A Freeboard represents the control interface for the BordFree where the user stands. It is made from a 6-wheeled skateboard where sideways tilting is allowed. The player can see their movement in the change of direction of the character by shifting their weight in order to tilt the board. using an accelerometer attached to the FreeBord, the ATmega32 microcontroller monitors the tilt. The images are stored as a buffer by using external SRAM.
