This document discusses the game Dance Dance Revolution (DDR). It provides an overview of how DDR works, including that players step on arrows on a dance pad as they scroll up the screen in time with music. It notes DDR can be a form of physical activity and some schools and universities have incorporated it into physical education programs. The document also outlines the technical components of DDR, including infrared sensors to detect foot placement, a control unit to manage the game and scoring, and how music and arrows are represented visually and synchronized during play.

2. Introduction to DDR
 Foot – eye coordination
 Hit arrows when they
match up on screen
 We use IR sensors
 One song, 4 difficulty
levels

3.  Dance Dance Revolution has a history of helping
students lose weight.
 Games are on the rise and this is one way that we
as physical educators can get the students moving .
 Let’s get the students in shape and have fun doing
Dance Dance revolution?
 Dance Dance Revolution provides very good
exercise, and even has an exercise program within
the game that tells you how many calories you
burn per song, and how long you work out.

location of foot to be
found
 Hardware:
-Sharp GP2Y0D02YK IR

10. Control Unit
 Two main functions:
– Game mode
– Scoring
 Game mode:
– Sends a 2-bit signal to
determine mode
 Scoring:
– Calculates score based
on how close arrows are
when position is reached
– Accuracy level displayed
during game, overall
score given at end.

11. Audio
 Audio Playback
– Song stored in ZBT memory
– Played through speakers using AC’97 codec
 Representation of song as arrows
– Row of arrows represented as a 4-bit number
– Each row corresponds to a beat of the song
– [left arrow, up arrow, down arrow, right arrow]
– If arrow represented by a 1, then it will appear in
the row

2 1000

12.  DDR is basically a dancing game. You select a song, and
then arrows pop up on the screen while the song plays.
The object of the game is to step on the arrows on your
dance pad (which corresponds to the game), as they
move down/up the screen. There are not really any rules
for this game-just try your best to step on the arrows,
and you’ll get better in time.

13.  Many schools use DDR as a physical education activity in
gym,and in Norway.
 Caltech allows its students to use DDR to fulfill part of its
physical education requirement, as students may design
their own fitness program.
 University of kansas (KU) has a class for Dance Dance
Revolution open for students to take as a 1 credit hour
course.

14.  Facilitates self-awareness
 Enhances self-esteem
 Reduces anxiety
 Encourages reminiscing
 Maintains and/or increases mobility
