Game Introduction

JUSTIFICATION FOR PROJECT

Market Analysis | Value Proposition | Prospective User

Functional Game

Ant Buster

Fastest selling consumer electronics de-vice

KINECT breaks Guinness recordKINECT Sells 10 Million Systems, Tops iPhone and iPad

KINECT GamesOnly 25 KINECT software, none of similar game.

Ant Buster

Value Proposition Helpful solution for parents

Prospective User For everyone, especially younger people

REQUIREMENT ANALYSIS

I/O Processing | Screen Transition | Game Logic Con-trol

Motion recognition, Getting joint coordi-nates

Input Processing

Graphic & sound information sent to user

Output Processing

User can switch between screens

Screen Transition

Game ≒ Set of rules ≒ Set of game logic

Game Logic Control

Motion recognition rate

Response time

GAME DESCRIPTIONBackground | Rule | Stages | Monsters

Background

Rule Bakery Bakery has constant HP Monster Approach to the Bakery Fixed Number of monsters

Game Clear Survive! kill every enemies Game Fail Bakery is siege by enemies

Stages

Monsters

Waiting few secondsAt the corner

Can not stompDuring defense mode

Summon monstersuntil death

Divide into lot of mon-sterswhen it stomped

Basic monster

Pass through way-point

Moving at the backwhen it stomped

Become slower and slower until min speed
