Beep Ball

A Wiimote-Powered Game For Blind Children

What is Beep Ball?

A sport designed specifically for the blind Similar to baseball Batter, fielders blindfolded Ball beeps for audio cues http://www.nbba.org/

Domain

Wiimote Challenges

Team OS choices: two Mac users, one Windows user No Wiimote API supports both these platforms, in any language Solution: develop a wrapper for other APIs!

Enough Complaining:

Design

Gameplay

MVC design pattern Many controllers; all managed by central gameplay logic Fielders, ball, player Multiple controllers and carefully-planned design allow quick substitutions For AI fielders or batters, just swap in a new controller

Interface and menus

Player accounts - selected and/or created at startup “No account” option available for quick play Option to record name for selection menu Tracks high scores, difficulty preferences

Interface and customization

Two types of difficulty: fielder skill and batting forgiveness Standard menu structure conventions Up/Down to select; menu items read aloud Left for more information on selected menu item Right to select/toggle

Issues

The Wiimote, obviously Fine-tuning gesture recognition Rest of API for game is very stable Fill-in-the-blank development once Wiimote is done
