AirRacquet System – Team Innovation 2/16
Introduction
Purpose: Gesture based racquet game with intuitive interface
Design: Iterative, user centered, changes motivated by feedback
Scope: Entertainment, training, research
AirRacquet System – Team Innovation 3/16
Conventional Systems
Improvement has been made in graphics and flexibility
User interface has remained static
User is more of puppet-master than player
AirRacquet System – Team Innovation 4/16
Benefits of AirRacquet
User is immersed into the environment
Gestures provide natural mapping to actual game play
AirRacquet System – Team Innovation 5/16
Design GoalsTypical User: Over the age of 12, familiar with ping-
pong, no knowledge of supported gestures needed
Focused on: Conceptual Model Feedback: Visual and audio Natural Mapping: Gestures and ball behavior Visibility: Menus and Game setting

Paper PrototypeFeedback
Possibility of error in menu selection
Unclear vocabulary
Improvements
Addition of deliberate selection gesture
Addition of “Add Default Setting”
Change of the word “Gravity” to “Bounciness”
AirRacquet System – Team Innovation 9/16
Initial Prototype Ball size varies
with proximity Racquet moves
with the position of the hand
Score displayed Help figure and
messages displayed
AirRacquet System – Team Innovation 10/16
Initial Prototype – Feedback
Strengths
Good visibility of the menu depth
Easy to grab the game concept
Game Weakness
Difficult to hit the ball Distracting instructions
flashing on the net Lack of feedback
during game play Pause state unclear

Alpha system
Options menu simplified
Start game in Main Menu
Feedback about winning and losing points
AirRacquet System – Team Innovation 13/16
Beta System
Pause figure moved Pause gesture changed Visibility: Colors modified How to: Audio added Gestures incorporated
Hitting/Clicking Selecting (Menu mode) Moving around (Game
mode)

HCI Principles
User centric approach Iterative design Importance of conceptual model Perception of system Feedback Natural mappings Gestures
AirRacquet System – Team Innovation 15/16
Future Improvements
Haptic feedback – ball impact on paddle
Network functionality – 2 player mode
Improved gesture recognition Rendering of the game setting
AirRacquet System – Team Innovation 16/16
Conclusion
User centered design Iterative Systems must incorporate proper
conceptual model Importance of natural mapping Importance of evaluating the user and the
environment first
