KINECT Games Only 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 Control

Motion recognition, Getting joint coordinates 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 DESCRIPTION Background | 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 seconds At the corner Can not stomp During defense mode Summon monsters until death Divide into lot of monsters when it stomped Basic monster Pass through waypoint Moving at the back when it stomped Become slower and slower until min speed

Demonstration

TECHNICAL ACHIEVEMENT Motion Recognition | KINECT development | Synchronization

Motion Recognition x y Same magnitude NO! a a a !a a z

KINECT do not use Cartesian Coordinates Motion Recognition

Finding the origin and up vector Motion Recognition Up vector Origin

Using Inner product with two vectors Motion Recognition Up vector Origin Inner product with [Vector from origin to foot] and [Up vector] Inner product with [Vector from origin to foot] and [Up vector] from origin to foot

KINECT development itself FROM SCRATCH No IDE, tools, references, etc. Synchronization With KINECT thread and game thread For solving performance problem Other Difficulties
